What can be cooked from squid: quick and tasty

Owners of laptops and computers often collide. When turned on, the logo of the motherboard manufacturer is displayed and nothing else happens. Then, if you wait a few minutes, the error ““ will often appear.

In this article, we will tell you why this happens and what you can try to do yourself to solve this problem.

Why it happens?

The fact is that at the initial start-up stage, when you just turned on the laptop and its logo is displayed on the screen, testing of the main components, as well as connected devices, takes place. The BIOS sends a request to devices and receives a response from them. If everything goes well, then the operating system is further turned on and started. In cases when the logo hangs on the screen for a long time (20 seconds or more), this means that there are problems with some of the surveyed devices. The BIOS just doesn't get a response from them.

Eliminating the problem

It consists in finding a device or internal component due to which the hang occurs. From experience we can say that very often the hard drive is the culprit. Especially if the hovering on the logo of the laptop manufacturer is accompanied by a distinct one.

Pin nick inside the hard drive board

To check this, it is enough to disconnect the hard drive and try to start the laptop without it. There is no hang on the logo - it means the hard drive is the culprit. But this does not mean that it needs to be thrown away and urgently run for a new one. It often helps on it.

If removing the hard drive did not affect the situation in any way, then the problem is not in it.

Removing the hard drive from the laptop

The next step is to remove the battery from the laptop for a few minutes. Also, it will not be superfluous to disconnect the internal battery. To do this, you need to remove the back cover.

After several minutes of inactivity without a battery, we put everything in place and try to turn it on.

There are quite a few cases when the keyboard hangs up because of the keyboard, which was once filled with liquid. Therefore, if you yourself can turn off the keyboard and start the laptop without it, then this option is definitely worth trying.

Disable keyboard in laptop for testing

Further, if there is no result, you should check the DVD drive. We are trying to extract it. Most laptops do this very easily. You just need to unscrew one bolt on the back side near the drive and pull it out, prying it with something thin.

The last thing you can try at home to solve this problem is to remove the RAM, wipe the contacts on it and reinstall it.

To extract the memory, we spread the metal latches to the sides

All other options are associated with serious interference with the motherboard. You may have to flash the BIOS or even change bridges (north, south). Therefore, if all of the above did not help you and your laptop still freezes when turned on on the manufacturer's logo, then it is better to take it to a specialized service.

"A-Iceberg" - 27 years with you. 5,500,000 million completed repairs.

If the laptop turns off and does not turn on, then often all standard attempts to start it do not bring the desired result. At the same time, there is no reaction to pressing the power button, the screen does not light up, all the lights are off (in some cases the battery indicator is on), the cooler operation noise is not heard, and the BIOS sound signals do not sound, accompanied by which the operating system usually starts. The presence of the above symptoms is a compelling reason to contact a specialist.

The engineers of the A-Iceberg Service Center promptly eliminate breakdowns of any level of complexity in one visit, regardless of the brand and model of the laptop. All work is done at home using modern equipment and high-quality consumables.

Why does my laptop not turn on after a sudden shutdown?

If the laptop turns off and does not turn on, the wizard decides what to do and how to diagnose according to the generally accepted algorithm for eliminating the causes of the following malfunctions:

• lack of voltage in the mains or violation of the integrity of the power cord
• breakdown of the power supply
• breakdown of the power connector
• battery failure
• short circuit of the microcircuits of the north and south bridges of the motherboard, malfunction of the controller of its power supply
• BIOS crashes

Specialists of the A-Aiseberg Service Center will carry out detailed diagnostics of the hardware and system parts of the laptop, repair or replace the power connector, power supply, battery and motherboard. All defective components are replaced with original certified spare parts.

How to troubleshoot

1. The disconnection of the device could be triggered by power surges or a discharge of the battery due to the lack of its power supply. Plug the laptop into a different outlet, or use a multimeter to measure the line voltage. If the value is below 190 V or above 250 V, then the problem is found. The power cable or wiring from the power supply to the power adapter may be damaged. In this case, the wizard will replace the power cord and worn out wiring.

2. If the indicator of the power adapter is off, and when a known good secondary power supply is connected, the laptop turns on, then the power supply needs to be repaired or replaced. Based on the cause of the breakdown, the master will replace the mains fuse, disk thermistor, power transistors or diodes of the diode bridge (they could be open or short circuit). In most cases, the breakdown is provoked by the swelling or oxidation of the capacitors, the replacement of which brings the power supply back to life.

3. If the power connector is faulty, then it is simply impossible to charge the battery or work from the mains. It is impractical to repair the connector, so the wizard will replace it by following these steps:

• disassembling the laptop with removing the motherboard
• unsoldering the board power connector using a hot air soldering station
• removal of old solder with a braid
• soldering the new connector into the pins of the motherboard using high quality gel flux
• cleaning contacts from flux residues
• assembling the laptop in reverse order

Advice! To prevent sparks from wearing out the power plug, plug the power cord into the power outlet only after connecting the plug to the power plug.

Note! Long-term operation of a device with a faulty power connector can cause burnout of a part of the motherboard and its power circuit.

4. Try removing the battery and connecting the laptop directly to the mains. If the device turns on, then the reason lies in the breakdown of the battery. The master will repair it, which consists in replacing batteries, temperature sensors and a temperature fuse that opens when overheated. If the laptop turns off when the battery is 60-65% charged, then you need to calibrate it.

5. A short circuit of the microcircuits of one of the bridges of the motherboard or a breakdown of the controller of its power supply can provoke an abrupt shutdown of the laptop. The device will not turn on until a specialist replaces the damaged electronic components of the chips on the north and south bridges.

6. The only non-hardware reason for the spontaneous shutdown of the laptop and its subsequent refusal to turn on is the presence of BIOS errors. The BIOS update procedure consists in installing a new firmware (compatible with the motherboard model) using a special utility. This will help eliminate critical errors and significantly improve the performance of your laptop.

Carefully! An unprofessional BIOS update (incorrect installation or incorrectly selected firmware version) often provokes a breakdown of the motherboard.

Why you can't do without the help of a master

Only an experienced specialist will be able to perform high-quality laptop repair and replacement of its spare parts without damaging the expensive electronics hardware. Self-elimination of malfunctions in most cases provokes a final loss of performance of the device or failure of its main components.

Professional repairs carried out in strict accordance with the manufacturer's recommendations will guarantee long-term and trouble-free operation of your equipment. Trust the specialists of the A-Iceberg Service Center, and today your laptop will be fully functional. A warranty card is issued to confirm the quality of the repair. Leave applications online on the website or by phone

Still, a person is so used to computers that he cannot live without them. It is scary to imagine a situation when you are left without an Internet connection, your favorite toy, office applications or cards. The material about typical breakdowns was being prepared for a long time, and at last it was ripe 🙂 Well, how matured… the editorial beech broke. What to do? You can immediately rush to the service, hoping for a quick and high-quality repair. And you can "screw up" a little yourself.

It is not so easy with beeches, due to their design features - there are enough problems. But the main malfunctions of the laptop are typical, which allows you to determine the approximate cost of repairs before going to the service. And this is not the only point. Breaks, as a rule, are the same. Moreover, users account for 95% of the causes of breakdowns. The rest of the interest is marriage and force majeure. Build quality, brand and cost don't matter. But the correct operation ... Let's talk about it today.

Why the laptop doesn't work

There is a lot of talk about quality. But here's the thing ... any brand has successful models, average and outright failures. Naturally, the coolest beechs cost a lot of money. But choosing a brand is not realistic. Remember "Yabloko" - expensive, fault-tolerant, "reinforced concrete" equipment, which nevertheless fails. Accidentally pushed a beech off the table, a hand twitched with a mug of coffee 🙂 did not notice the typewriter on the couch or forgot the USB flash drive on the keyboard - but you never know reasons to mess up.

Why the screen does not work on a laptop

You think this is a strange question. Nothing like this. When buying a beech, smartphone or tablet, know that the most delicate part about it is the screen. In expensive models, this is not so categorical. But in low-cost technology, a breakdown of the matrix can make you turn gray. Half the cost of new beech, sometimes more. How does it feel? So the screen can be called the most vulnerable part of the beech. So, just a moment of attention 🙂 we will figure out how to protect ourselves from such a disaster.

IMPORTANT! Use the services of official services. Yes, it is more expensive than that of unofficial private traders. But the spare parts are probably branded, and not only the direct contractor, but also the brand as a whole, is responsible for the quality of the repair. There should not be any problems with the search - every large city - read, regional center - has representative offices of large firms. You can do it easier, go to the offsites and find an address, for example, CANON or Samsung.

How does it usually happen? There are actually few reasons, and they all relate, if I may say so, to popular laptop malfunctions.

• Accidentally pressed on the screen. There are several options. The beech does not have to be open. Breakdowns can also occur with closed appliances. So we leave the laptop where we cannot accidentally sit on it or drop it, for example, a vase.
• The lid was closed or opened abruptly, especially around one corner. As a result, the matrix may crack or the loop may come off.
• Forgot a USB flash drive, pen or other trifle on the keyboard. In this case, the screen will definitely crack or crack.
• The last type of reasons is associated with a factory defect or wear and tear of components. For example, cloudiness of the matrix or the appearance of dead pixels, abrasion or fracture of the loops.

Replacing a broken screen for popular models takes place at a time. The fact is that spare parts are constantly in stock. But for top-end or exclusive beeches, you will have to wait for delivery from the company. In any case, repairs are real, albeit expensive. So let's try to get by without these problems. What should be done to make the LCD matrix live for a long time and delight us with the picture? Not so much:

• Try to work at your laptop on a desk or other designated work area. Putting the equipment on your knees, the back of a sofa or a kitchen table, you increase the risk of breakage;
• Open and close the lid without sudden movements, taking the middle. Neatness has never harmed anyone yet 🙂 The hinges themselves rarely break, but you can easily pull out the fasteners.
• Before closing the laptop, take a close look at the keyboard and surface. We remove unnecessary items. Haste and carelessness again. Be careful not to change the screen.
• Make it a rule to do an annual inspection of the beech. This is useful for more than just loops and cables. Prevention will show whether it is necessary to replace the thermal paste, remove dust and dirt. In general, the right thing.

Why the keyboard does not work on a laptop

The keyboard and touchpad are ahead of the rest in terms of the frequency of calls. Individual keys fail, the entire keyboard fails, the touchpad stops responding adequately to touches. Like most laptop breakdowns, the main reason is careless handling. The probability of a factory defect tends to zero, but coffee, tea, juices or mineral water are the absolute leaders. In most cases, it is sufficient to replace the "broken" parts.

• Broken buttons change quickly, and for a penny cost. If the mechanism is "crushed", either we change the keyboard completely, or use it without several buttons.

INTERESTING. The first laptop, called the Grid Compass, was commissioned by NASA in 1982. The device ran on a processor with a frequent 8 megahertz and 340 kilobytes of RAM. The first Shuttles were equipped with these devices. Laptop computers ran on the same hardware as their desktop counterparts until 1990. In the early nineties, Intel began producing processors for mobile technology.

• A small spill will make it easy to replace the keyboard. If you react quickly. Often, liquid will spill onto the motherboard. In this case, it is impossible to determine the extent of damage without careful examination and testing.

The worst in terms of repair is the case with super thin models - the keyboard is built into the front cover. Accordingly, the cost of the spare part is quite high. And for replacement, you will have to completely disassemble the beech. In most models, the keyboard can be easily changed without disassembly. Unscrew at most 2-3 bolts and unscrew the fasteners. The situation with the touchpad is more complicated, you cannot do without disassembly.

Why isn't the touchpad working on my laptop? Only a strong blow or ingress of liquid can damage the control element. Well, there are no complex microcircuits or super complex designs there 🙂 But for the thinnest tracks and loops, a drop of water is enough ... and now the user is uselessly running his finger over the surface. Overly emotional players often push the touchpad in the places corresponding to the mouse buttons.

IMPORTANT! If liquid gets on the surface of the laptop, no matter how much, quickly turn off the power, remove the battery, and take the device to a service center. Lack of power will stop galvanic corrosion and prevent damage from spreading. It will not work to remove the liquid on your own - with a hairdryer, drying on batteries. Only make it worse.

If the keyboard is out of order without a spill, then you can replace it yourself. We buy the necessary model, carefully take out the "broken" one and insert a new one. Naturally, on the switched off device 🙂 But we still recommend contacting specialized organizations. Pay extra pennies for the operation itself, but you will receive a guarantee for work. You don't have to "bite your elbows" if something happens.

Why laptop is slow

Brakes and friezes are common in any computer, especially beech. The internal organization of mobile technology allows dust to quickly accumulate and hinder the outflow of heat. This primarily applies to active cooling systems. The cooler drives the outside air through the cooling system, naturally along with dust. The worst of all is in the summer or during renovations. Beech clogs faster in smokers 🙂

The second problem is pets. With short-haired individuals, for example, Siamese or dachshunds, there are fewer problems. But long hair appears not only on sofas and clothes. The fan quickly becomes clogged with woolen balls. It is not difficult to understand that the problem with the beech is not difficult. It's not just about software inhibition. When overheating, the temperature is felt through the plastic of the case. It is enough to touch with your hand.

Another symptom is fan acceleration. The smart system increases the speed in an attempt to cool the processor and graphics card. Therefore, the cooling operation becomes much noisier. You just need to pay attention to this. The result of overheating is at least an unexpected shutdown of the laptop. In the most advanced cases, processors, video cards, motherboard chips "burn out" and for some reason the Internet does not work on a laptop.

ADVICE. If you can't do preventive maintenance, take your laptop to service at the first symptoms of overheating. A typical misconception - it is enough to vacuum the disassembled beech - often ends up with broken off capacitors, short circuits or poor-quality removal of contaminants.

Simply removing debris from the fan is not enough. Dust accumulates over the entire inner surface. The high temperature causes the thermal paste to dry out. In general, it is necessary to solve overheating in a complex way: removing dust, replacing thermal paste, checking contacts for oxidation. It is almost impossible to do this at home. Especially for a layman. Let's repeat - the price of service is differently lower than the problems caused by "crazy" pens.

The main malfunctions of the laptop. Power problems

Often people turn to the service with the words “the laptop does not turn on”. There may be several options. There are problems with the motherboard, and the "dead" battery, and problems with external power supply. Cases of defects in batteries are very rare. As a rule, problems appear when using a non-native memory or storage with a full discharge. Remember, any battery is limited in the number of charge-discharge cycles.

Gradually, the resource is depleted, and after a couple of years, the battery must be replaced. In budget models, it is easy to replace the battery yourself. The main thing is to buy the right battery. We take out the old one, carry it to the store. The labeling seller will select the desired model. Can be ordered online. In this case, please state the brand of the laptop and the battery parameters accurately. Super thin beeches are trickier. Built-in battery - provide a replacement to the specialists.

The standard charger can "fly out" due to voltage problems, but more often the reason is our inaccuracy. Try not to bend or kink the cable, check the tightness of the contact in the socket and laptop socket. Do not let your pets play with the charger 🙂 If the power supply fails, try to replace it with a similar one. You can use universal models, but you have to accurately observe the current parameters.

Why does the microphone not work on a laptop

The last common problem is connector problems. Look at your beech carefully. Depending on the model, along the perimeter there are microphone and headphone jacks, a twisted pair connector, several USB ports, hdmi and other communications. What breaks most often? That's right, what we use daily and hourly. According to service statistics, the largest number of breakdowns occurs in the usb connectors and the headphone jack.

If the microphone, headphones, or usb are located directly on the board, repairs are more difficult and expensive. In the case of a daisy-chain connection, replacement is quick and cheaper. In the first case, you will have to not only change, but also solder. In the second case, a simple replacement. In the case of sound, the situation is more complicated. Why doesn't sound work on my laptop? If you use external speakers, the 3.5-inch or usb connector is out of order. If you can't hear the native speakers, you will have to look for the reason.

INTERESTING. A separate class is stripped laptops called "off-road vehicles". Such models are being developed specifically for use in extreme conditions. There are models for tourists 🙂 But the "SUV" is rather a powerful computer for working in aggressive environments - strong dust, harmful gases, possible emissions of chemicals, high temperatures, and so on.

You should be careful with the connectors anyway. Whether you use a USB modem for the Internet in the country, whether you connect external speakers or a mouse - check the condition of the plug on the device and the power requirements. Sometimes there are models of external hard drives that need to be connected with two cables. One is not enough to spin the disc. A crooked plug and high demands can lead to serious breakdowns.

You won't be able to figure out the ports on your own, don't even try. Such problems are rectified only at service centers. The user is left with one, but very important thing - to properly operate the laptop and respond promptly to emerging problems. As with the disease 🙂 noticed on time, faster and cheaper cured. And questions like "Why doesn't the mouse work on the laptop?" will not arise.

Good luck for this. Read "BEARDS", be aware of all the interesting things!

There can be a lot of reasons why the built-in screen on a laptop does not turn on. If the monitor does not light up, this does not mean that the computer has become unusable. Novice PC users immediately turn to specialists for help, but in reality, most black screen problems can be solved on their own. Initially, in any case, you need to reset the hardware settings and only then start troubleshooting yourself.

The main causes of failure

In total, there are several dozen breakdowns that can lead to malfunction of the laptop screen. For convenience, they can be divided into several groups:

• Malfunctioning battery or charger.
• Problems in the hardware configuration of the laptop.
• Memory failure - falling out of the socket.
• Broken loop of the screen, backlight or matrix.
• Malfunctioning or breakdown of the video card.
• Damage to the motherboard due to overheating or damage.

Not all breakdowns and malfunctioning of laptop elements can be fixed by a PC user, some problems can only be solved by a specialist in a service center. What are the ways to troubleshoot at home, you need to disassemble in detail.

The most serious and common problem is the malfunctioning of the video card. To understand if the video card is functioning properly, you need to install an additional external monitor. If it does not work, then the graphics adapter is faulty.

If manipulations with hardware settings and BIOS firmware do not help, and all cables and components are installed correctly, you need to seek repair help

It is not recommended to independently manipulate the replacement of components on a laptop without certain knowledge in the field of electronics and skills in working with a computer. If the problems cannot be solved without interfering with the internal parts, then it is better not to risk it and seek help from a repair specialist. If you independently carry out irrecoverable manipulations that will lead to fatal breakdowns, then the costs will be more than for repairs. In this case, you will need to purchase a new device.

Display analysis

If there are concerns that the reasons for the dark screen are related to its malfunctioning, then you should first check if the video card and motherboard are working.

To do this, an external display is connected to the laptop using an HDMI or VGA connector. If the external monitor turns on after booting up the computer, then the problem is in the screen or backlight loop, or in the display itself.

It is important to start turning on the laptop after the external monitor is connected to the connector. Also use the keyboard shortcut to switch between monitors. In ASUS and many other models, these are Fn and F8.

More often, breakdowns are not related to the video card - to check this, connect a separate monitor

Further in this article, all the steps for eliminating hardware settings and recommendations for working with various applications can be carried out with a non-working display - by connecting an external screen via the VGA / HDMI port.

Before starting to manipulate the details of the computer, you need to carry out a standard reset of the hardware settings of the device. In most cases, this will fix the black screen problem.

The hardware reset is performed as follows:

1. The laptop is disconnected from the mains.
2. The battery is removed from the device.
3. The power button is held down for 25 seconds.
4. The device battery is reinserted.
5. The charger is connected.
6. The laptop can be turned on.

After resetting the hardware settings, if the laptop boots, it will ask you to select the type of startup of the operating system - you need to select "Normal Windows startup". But problems are also associated with the BIOS, which can be reset just as easily. If updating its drivers and resetting with the option does not help, then you will need to disassemble the laptop.

Solving problems related to settings in BIOS

Resetting the BIOS settings will help if manipulations were carried out in the BIOS before the display malfunctioned. Using the keyboard, resetting is done in two ways, the first using the keys:

1. After turning on the laptop, the "DEL (Delete)" key is pressed.
2. The settings are reset by pressing "F9".
3. The configuration is saved with the "F10" key.
4. The laptop restarts.

If you do not press any button in time or do everything quickly, the BIOS settings may not be reset, and this will not be reflected on the display due to its malfunction. In this case, removing the CMOS battery will help, which allows you to store the BIOS settings even when the computer is turned off.

To reset the settings, you need to remove and reinsert the CMOS battery

Troubleshooting possible RAM problems

After the scheduled cleaning of the laptop from dust, it may happen that no lights turn on and the display does not work. This usually happens if the RAM bar was installed incorrectly. There may be problems both with RAM and with the operation of other loops - in any case, you will need to disassemble the device and check if everything is connected correctly. To do this, the laptop is simply disassembled and all elements inside the computer are checked for connections.

A failure in the operation of the RAM can occur after a liquid spilled on the keyboard or due to high humidity. In order to solve problems with the RAM slats, you need to take the following steps:

After that, all the parts are assembled back and the bolts are screwed into place. If the procedure for detaching and reinstalling the brackets did not help, then there may be problems with other parts of the computer. Most often, loop breaks, short circuits or backlight breaks occur - in any of these cases, you need to contact a laptop repair specialist at a service center for help.

Installing the current BIOS version

If the external monitor is working properly, but the display of the laptop itself is not working, while resetting the hardware settings and returning to the factory BIOS options did not help, then installing a fresh version of the BIOS can help.

There are several ways to update the BIOS:

• Using the "MS-DOS" mode.
• Through the operating system.
• Without entering DOS and running Microsoft Windows

The easiest way to download BIOS updates is by using dedicated software. But it would be right to visit the manufacturer's official website on your own and download updates on it.

Even a novice PC user can quickly update BIOS with Everest

In any case, before installing a new version of the BIOS, you need to make a backup copy of the operating system or save the access point. If you do not do this, it is possible that a complete reinstallation of Microsoft Windows will be required due to the fact that all operating system settings are lost.

If the display has a black background with a cursor

If the computer or its components overheat, the screen may turn off completely, or the image may disappear partially. Most often, such failures occur when the video card overheats. In this case, a complete shutdown of the device and its cooling will help.

It is necessary to constantly check the temperature of devices inside the computer, to avoid troubles, use the free application "Priform Speccy".

The temperature of the video card is listed in the "Graphics Devices" section.

In the same utility, you can find out the temperature of other devices, overheating of which may cause problems with the display:

• The CPU may overheat cause the monitor to turn on and off abruptly.
• If the system board overheats, there may be malfunctions in all elements of the computer.
• If the hard drive overheats, there will be problems with applications and files on the laptop.

After a configuration failure or a malfunction occurs in the laptop, the only way to restore the functionality to breakdowns is to perform a secure computer boot procedure.

Secure boot procedure

It happens that the computer automatically reboots after turning on and its monitor does not work. In this case, you need to perform a secure boot, as follows:

1. When the device starts to boot, you enter the "Additional boot options" - the "F8" button (in some laptops this is the DEL button or various key combinations, it is better to look for information about the motherboard on the Internet).
2. Additional boot options select one of three safe mode flavors to start.
3. After that, you will enter the operating system through safe mode.

You should choose the mode that is more convenient to work with - if you do not know which one is suitable in your case, you can first try the standard "Safe Mode"

Safe mode can be started in other ways, for example, through the applications "cmd" and "msconfig". Both utilities can be launched by entering their name in the search bar of the Start menu.

In safe startup mode, the following settings must be made in the computer:

• The device turns on.
• When Windows is fully loaded, the Control Panel opens.
• The "System" is launched in the "Control Panel".
• Next, "Advanced system settings" opens.
• In this window, you need to run "Advanced", and then "Startup and Recovery".
• Here go to the parameters and uncheck the "Reboot automatically" box, after which the settings are saved.

This procedure will allow the next time the computer is turned off, an error of the form "0x000000000 NO_DEVUCE_BOOT" will be displayed on the computer screen. How to fix a certain type of error can be found on the official Windows website or in other reference books on the Internet.

Safe Mode Failure Remediation Procedure

If, after starting the laptop in safe mode, the computer still automatically restarts, then you need to perform a "System Restore". To do this, immediately after the computer starts booting, you need to press the "F8" button. After that, in the operating system recovery menu, you need to select the OS version to which it is convenient to return: you need to select that period of time when the display functioned correctly.

If it turned out to start the operating system and the monitor started working, then you need to update the video card drivers and BIOS. Even with a properly functioning screen, you need to update the drivers constantly, with a frequency of at least a month. It is better to set up automatic driver updates to avoid problems with their work.

If the problem is caused by malicious applications

The cursor on a black background can be either an indicator of a hard disk malfunction or a consequence of changes in the work of malicious viruses

If the laptop display malfunctions due to harm caused by viruses or malicious utilities, you need to check for their presence with an activated antivirus program. If removing the malware does not help, you need to perform a system restore or a complete reinstallation of Windows.

Troubleshooting a crash using bootable external media

On computers with Windows versions "8" and "10", system recovery can only be performed using a bootable USB flash drive.

The procedure for troubleshooting a crash using a bootable removable media is as follows:

Other types of recovery using a bootable flash drive can also help, for example, "Startup Repair" is convenient if there are no up-to-date OS restore points

Solving other black laptop screen problems

If all the above methods of fixing the malfunctions did not bring the desired result, the only way to fix the problems of the non-working screen would be to contact the service center to a specialist. The master solves such questions in a couple of working days, if the repair office has the necessary components. In other cases, repairs may take several business days.

Problems can be in any of the parts of the laptop, only a specialist can determine which component has ceased to function

If the monitor stops starting when you turn on the laptop, you need to check the operation of the computer by connecting an additional external monitor. If it works, then you can try to reset the hardware settings, change the settings in safe mode, install the drivers, and try to fix the problem in other ways. If it does not function, then the problem is a malfunction of the video card. Most often, problems with a black laptop screen are solved by resetting the hardware settings. If none of the above helps in fixing the problem, then the only way is to contact the service center for help from a computer repair specialist.

An attempt to connect to a Wi-Fi network can lead to the laptop finding a network, connecting to it, but not being able to use the Internet. If the laptop notices the lack of Internet access when the network is connected, it will warn you about this with an icon in the form of a yellow triangle next to the connected Wi-Fi icon.

Reasons for the lack of internet

The cause of the problem lies either in the router, or in the Internet connection, or in the laptop itself, so the methods described below will help you solve it in all cases. Perhaps the Internet itself does not work due to problems on the operator's side, or a failure occurred in the router that allowed the loss of the network, or the laptop incorrectly recognized and used the network.

The list of possible reasons is wide, it is necessary to narrow it down. First of all, take another device, for example, a phone or tablet, and try using it to access the Internet through the same Wi-Fi network. If you can do this, then the problem is exclusively in the laptop.

The laptop reports that there is no internet access

If the Internet is not available on other devices, then you need to understand if the reason is in the Internet cable or router. To find out, you need to try using the Internet connection directly through your laptop. Remove the modem or cable from the router and plug it into the port of the device, connect and check if there is Internet access. If the answer is no, then the problem is in the modem itself, the wire, or on the operator's side. In any case, the way out of the situation is to contact the support service of the company that provides you with the Internet. Their contact numbers are on the official website.

If the direct connection gave a positive result, then it remains to blame the router, so you must use the instructions associated with it.

Solving the problem on the laptop side

If, in the course of the above instructions for identifying the cause of the breakdown, you learned that the network does not work exclusively on a laptop, then sequentially use all the methods below. One of them will most likely give you back access to the Wi-Fi network.

Reconnection

Open the network control panel, disconnect from Wi-Fi and reconnect. Perhaps this time the laptop will be able to correctly configure all the network parameters, and Internet access will return.

Disconnect from the network and reconnect to it

Reboot

Restart the laptop, during this process all processes on the system will restart. Re-enabling them will cause the hung elements to start working.

Restart your computer

Deactivating antivirus

Every modern antivirus has a built-in Firewall (firewall), which ensures security when working on the Internet.
