The keyboard on the laptop works, what to press. The keyboard does not work on the laptop: the main causes of the problem

Computers are devices that help us organize our activities and leisure time. The breakdown or malfunction of a certain system component is a completely acceptable and common occurrence in the operation of any personal computer(PC).

Faults are conventionally divided into two classes: hardware failures and software failures. Hardware-type malfunctions imply a breakdown of the physical components of the system. In some cases, software glitches can cause problems with the physical components of a personal computer.

The main reasons for laptop instability

Laptop is unified system all computer elements. Due to its compactness, it can be easily transported from place to place. This is why such computers are more likely to be damaged. You should know the basic rules for using laptops and possible breakdowns if these rules are not followed:

1. Do not turn on your laptop immediately after bringing it in from the cold. Motherboard and CPU may fail due to sudden temperature changes.
2. The most sensitive and breakage-prone element of a computer is the screen. The matrix should not give in to pressure. Before closing the laptop lid, make sure that there are no foreign objects left on the keyboard.
3. The hard drive is subject to various types of vibrations and magnetism. Do not keep magnets near your laptop. Should be done periodically backups all hard drives.
4. Much attention should be paid to the laptop battery. Replacing such a part is quite expensive, so you should follow the basic rules for safely charging a laptop battery. If possible, connect to electrical network. Once a week, after charging the battery halfway, place it in a cool place for a few hours. This will extend her life by a quarter.
5. Always disconnect the Internet cable from your laptop during severe thunderstorms.
6. Avoid overheating your laptop. This may lead to unstable work programs and CPU failure.
7. Do not keep liquid near your laptop. If water gets on one component, there is a high risk of flooding another element. For example, if water gets on the keyboard, the processor, speakers, touchpad and motherboard may also be flooded.

Why don't the keys on my laptop work? Common causes of breakdowns

On laptops, the keyboard fails quite often. Quite common reasons for this are listed below:

• Outdated or uninstalled drivers.
• Computer virus or other spyware.
• Large accumulation of dust inside the keyboard.

• Sudden change in laptop temperature.
• Failure directly on the motherboard.
• Malfunctions in the operation of individual keys caused by mechanical damage.
• Storing a laptop in an area that is too humid.
• Incorrect BIOS operation.

All of the above causes of breakdowns can be eliminated yourself, or you can contact a service center. If you urgently need to use the keyboard, but the one built into the laptop is still faulty, then you can use virtual keyboard. You can enable it by going to the control panel. In the menu item called Accessibility, you can connect a virtual keyboard. When the keyboard on your laptop does not work, you can use an external portable laser or USB keyboard for a while.

If you notice a laptop failure and the device is still under warranty, take advantage of it. In this case, professionals will repair the laptop, minimizing the risk of another similar problem.

If absolutely all the keys on the laptop stop working, then the first thing you need to check is the presence latest version installed drivers input devices. To do this, go to the official website of your computer manufacturer and download the software from the Drivers section. To do this, you need to specify the device model and the version of the operating system installed on it. After specifying this information, you can select the type of device for which you need to download a driver (audio, graphics, input devices, camera, and so on). Install the downloaded software and restart your computer. If the problem was in the drivers, then after a reboot everything will work stably.

Problems with any component of your computer may be the result of downloaded spyware. software or your computer is infected with a virus. Install or update an existing one antivirus program and scan your system for threats. Remove any viruses found and restart your computer. In some cases, the antivirus is not able to remove malware and you may need to reinstall the operating system. It is imperative to do this because the virus not only disrupts the operation of laptop components, it can steal your personal data, passwords and bank card numbers.

Damage to the cable that connects the keyboard to the motherboard. Such a breakdown requires physical intervention in the system. You should disassemble the laptop components in a specialized workshop, since at home there is a risk of losing tiny parts, without which the laptop will not be able to function in the future. The breakdown can be corrected by replacing the damaged cable.

Sometimes there are glitches in BIOS operation or Basic Input-Output Computer System cause I/O devices to malfunction. You can easily fix this problem even without special equipment repair skills. In the first five seconds of turning on the computer, call up the BIOS menu by pressing Delete keys(Del) or F2 (BIOS enable keys on laptops different models may differ). If the computer recognizes the button press and the BIOS turns on, then you can safely restart the computer again. Everything should work.

The key on the laptop does not work. How to clean and replace keys yourself

A large accumulation of dust inside the keyboard can cause individual keys to not work. Thoroughly cleaning the dirty keyboard with a brush may solve the problem.

The first step is to detach the keyboard from the laptop. There are several options for mounting the keyboard. To remove the keyboard follow the instructions:

1. Turn off the device and remove the battery to prevent it from turning on unexpectedly.
2. Using special plastic squeezers (they can be purchased at any service center or hardware store), open the keyboard mount. If there is no plastic wringer, you can use a regular one. plastic card, which is available in every wallet.

1. You can read about the location of the mounts on the computer manufacturer's website.
2. After unpinning, disconnect the cable from motherboard and gently clean the keyboard with a brush. Try not to use detergents.
3. After completing the cleaning procedures, reinstall the keyboard in its original location.

If a key on a laptop does not work, then it is not necessary to detach the entire keyboard. You just need to remove the individual key and replace it. Separating the key is quite simple: you just need to carefully pry it off with pliers or tweezers. Then you should clean the area underneath. There is a special mechanism under the button. Under no circumstances should it be filled with glue or water.

Liquid spilled on the laptop keyboard

If liquid gets on your laptop keys, you should immediately follow these steps:

1. Disable your laptop computer from the power source.
2. Remove the battery.
3. Turn the computer upside down with the keyboard facing down before the water reaches electrical contacts and motherboard.
4. In this state, the laptop needs to be dried for at least two days. It should be noted that in no case should you subject your laptop to heat treatment: dry it with a hairdryer or using a warm radiator, and so on. This method can damage contacts and important microcircuits inside the device.
5. For best effect Unhook the keyboard, and attach a natural cloth to the laptop, which should still be upside down, with a handful of rice hidden inside. Rice can absorb moisture very quickly.

If possible, contact the laptop manufacturer's service center for repair of flooded keys. The above drying methods may not be helpful. If too much water has been spilled on your computer large number liquids.

After installing the new Windows, some users received complaints about problems with the keyboard. This kind of trouble can happen for a number of reasons. Let's look at why the keyboard on a laptop does not work in Windows 10 and what to do about it.

Causes of the problem and how to fix it

All problems with non-working keyboard can be divided into two categories: hardware and software. Even if the breakdown occurred after reinstalling the OS - physical damage it is possible. Let's take a closer look at the reasons.

Hardware problem

Think carefully, have you spilled any liquid on your laptop in the recent past? If your answer is “Yes,” everything fell into place. “It can’t be, I quickly turned off the car and dried it,” you might think. But the problem is that the oxidation process does not occur immediately and after some time it can reach microcontrollers or other important parts. Therefore, in this situation, it is recommended to replace the qwerty device.

If the keyboard has not taken a bath, the problem may be hidden in the connection connector. Considering that it is built-in in laptops, this mainly happens with individual devices connected to a desktop PC via USB and PS/2. Among them:

• oxidation or damage to the loop;
• poor contact due to wear of port parts;
• burnout of conductors due to a voltage surge or short circuit.

IN in this case you need to reconnect the device to another connector, clean the contacts and, if you have the appropriate experience, disassemble the device and carefully check the internal condition. If you find yourself in a similar situation with a laptop, find instructions for disassembling it and reconnect the connector to the cable. But if you are afraid to do this or lack experience, contact the service center.

Driver corruption

There are situations when driver installation ends with errors. However, the user is not always aware of this fact. Therefore you need to delete the existing one digital signature and replace with a new one. To do this:

1. Open “This PC” – “System Properties”.
   
   
2. In the new window, find and click on the “Device Manager” button.
   
   
3. Find the “Keyboard” subsection and expand it.
4. Right-click on the device and select “Delete”.
   
   
5. Restart your computer.

After turning on the PC will automatically install the device driver. If for some reason this does not happen, visit the official website of the laptop or keyboard manufacturer and download the required digital signature from the corresponding page.

Changing BIOS Settings

This next reason, which causes the keyboard to malfunction. For use this method need to:

Attention! IN BIOS keyboard should work even without drivers. Otherwise, return to the “Hardware problem” item.

Virus activity

In some cases, this situation arises due to the activity virus programs on the computer. To diagnose and remove them you need:

If this method does not help, you should definitely seek help from specialists. The problem can be quite serious.

Using the on-screen keyboard

Yes, the keyboard doesn't work, but you still need to type somehow. This is where the mouse and on-screen keyboard come to the rescue. To enable the feature, do the following:

That's all. Now you know why the keyboard on a laptop does not work and what to do in these cases. If you lack the proper experience, do not risk disassembling and repairing devices yourself - this may damage them forever.

A non-working keyboard is always a problem. It's one thing if you have desktop computer: went to the nearest store and bought new keyboard. But what to do if the keyboard on your laptop doesn’t work? The problem is not typical and it can be solved in different ways depending on what caused it: starting from mechanical faults and ending with absence necessary drivers in the operating system.

Causes of failure

It cannot be said that the keys on HP-branded laptops function better than those on ASUS. Everything depends not only on specific model, its cost, but also because of exactly how you use the keyboard - after all, you can spill your morning coffee on it, and then be indignant at why it stopped working after a week or a month.

Why might the keyboard stop working?

In other words, if you want to save not only money, but also gain useful experience, it makes sense to “sweat” on restoring your performance.

Software failure

How do you know if it's a software glitch or not? Everything is quite simple, we need to get to the BIOS. Turn off your laptop, press the power button once and launch the BIOS by pressing one of next keys: ESC, Delete, F1, F8, F12 or F2. How do you know which one is right for your case? There are several options here:

1. Read the instructions for the laptop that came with it;
2. Try all the options one by one;
3. Be careful and when you start the laptop, read the very bottom line, it will say which button is responsible for exiting to the BIOS. For example, in the case of laptops ASUS– this is F2 or ESC.

Now let's figure out how to get into safe mode. In fact, there is nothing complicated about this - everything can be solved in just a few clicks:


Now try to check the functionality of the keyboard, if it starts to function normally - the problem is only in the drivers. If he continues to plot, then the problem is in the OS itself - probably some kind of failure has occurred and you will need to reinstalling Windows.

How to boot in normal mode

Driver failure

So, you need to find either DriverPack Solution, or Slim Drivers - these are programs with huge sets of drivers, which are called for every taste and color. There will probably be some for your laptop model. Install them, restart the computer and, if the problem has resolved, continue using the laptop. If the problem persists and the keyboard works in the BIOS, you will have to go to extreme measures- reinstall operating system.

Oxidation of contacts on the cable

There is no way to do this without disassembling the laptop. There are only two options - try to repair it yourself or immediately take it to a service center. If you are confident in your skills and have the necessary screwdrivers, then you can try to do without service center. In addition, this is quite possible, provided that you do everything exactly according to the instructions taken on the Internet. It is enough to visit the same YouTube video service and see how your laptop model is disassembled.

If the problem is really in the contacts, then you just need to clean them (with a cotton swab dipped in alcohol). Literally an hour of work and the keyboard on the laptop will work as before again. If the contacts are damaged and not oxidized, you will have to replace the cable and run around the shops looking for it.

As you can see, almost any problem can be solved at home. If you doubt your abilities, it’s better not to take risks and take your laptop to a workshop.

User question...

Hello.

Help with one problem. Out of the blue the keyboard on my Lenovo laptop B70-80. The laptop did not hit, did not flood, did not hit - just after turning it on, it did not respond to pressing some keys. What can be done?

Good day!

What is good in this regard regular computer- that's how it is quick change one keyboard to another. Unfortunately, this procedure cannot be accomplished so quickly on a laptop.

In general, for the keyboard to stop working for no reason is an extremely rare case. Most often, the user guesses what the reason is (and sometimes remains silent). For example, quite often the keyboard is flooded with tea, water, juice; mechanical damage etc.

In this article, I will look at the main reasons why the keyboard fails to work, and what can be done to restore the device’s functionality. So...

The keyboard on the laptop failed: reasons

What can be done to temporarily correct the situation?

I would like to start the article with what temporary measures can be taken in order to at least somehow type some characters and press the necessary keys (which may be needed in the process of restoring functionality).

1. Method No. 1- connect a USB keyboard. So that any modern laptop has several USB ports. By the way, if the USB ports also do not work, then this is a rather bad sign and may indicate a faulty motherboard. fee;
2. Method No. 2- call on-screen keyboard. It is located in the section: Control Panel/Accessibility/Center special features (see screenshot below).

1) User inattention/ignorance

No matter how funny it may sound, very often the keyboard “does not work” due to the user’s ignorance. For example, how many times have people complained to me that the numbers on the keyboard are broken, that dates cannot be entered, etc. - but the fact is that the numeric keypad works when the key is pressed Num Luck(by the way, there is often an LED on it or above it).

So, if this key is not pressed, when you try to enter numbers from the numeric keypad, your cursor will jump, move, and not respond at all.

If your numbers don't work, be sure to pay attention to this key!

Note: some laptop models include numeric keypad only by pressing the key combination: Fn+ Num Lock.

By the way, one more point: regarding the function keys (F1, F2, F,3... F12). On modern laptops In order for any of these keys to work, you also need to press the FN key. Usually, this moment is configured in the BIOS.

The screenshot below shows the "Advanced" section Dell laptop- in the "Function Key Behavior" item - it is possible to choose how they will work function keys: in multimedia buttons mode (volume down/increase, brightness, etc.), or in mode normal functions(refresh the page, call for help, etc.).

I won’t go into detail here on how to enter the BIOS and how to configure it, but I will provide a couple of links to articles from which you can glean this information:

1. how to enter BIOS -
2. buttons to enter BIOS for different manufacturers laptops -
3. how to reset BIOS settings -

2) Debris under/between the keys

Dust, dirt, crumbs love to accumulate under the keys of the keyboard, and in general, the keyboard gets greasy over time from greasy hands and fingers, even for fairly neat users. Over time, some of the keys (usually starting with 1-2) stop responding normally, and you have to press and press hard on them.

An article about how to clean your laptop/PC from dust. Link to the section of the article about how to clean the keyboard from crumbs, greasy marks and dust -

There are three ways to clean the keyboard (in my opinion):

1. use special A USB vacuum cleaner that can accurately and carefully collect most of the crumbs from the surface of the keyboard;
2. use special Velcro, which when you press them fill the plane of the keyboard, and when you unhook them, all the dust and dirt remains on them;
3. You can blow off the keyboard using a regular vacuum cleaner (especially if it has a reverse mode), and then gently wipe it with a damp cloth soaked in soapy water.

3) Software failure, error loading OS

If not a single key on your keyboard works at all (and you didn’t flood it, didn’t knock, etc.), then I hasten to assure you that in more than half of the cases the software is to blame. For example, a driver conflict might occur during the loading stage of your OS, or you might have picked up some kind of virus, etc.

The easiest and surest way is to try rebooting your laptop first. It would be a good idea to try entering the BIOS (how to do this, see this article:).

Note: if your keyboard works in the BIOS (and the fact that you entered it already indicates this) - then the problem is probably in the software. In case of hardware problems, the keyboard will not work anywhere: neither in the BIOS, nor in Windows, nor in any other OS!

If after rebooting the laptop the keyboard does not work again (and the keyboard worked in the BIOS), try rolling back the system to the state when it worked. Below is a link to an article on restoring Windows.

How to restore Windows 10 -

If recovery doesn't help (or you don't have control points for recovery) you can try. I also recommend paying attention to the drivers, more about them below...

4) Problem with drivers

In general, usually, keyboard drivers are installed automatically when Windows installations. But sometimes the following problems occur with them:

• Some laptops have several standard keyboard with additional functions - and for her full-fledged work specials required drivers. If they are absent, the keyboard may not work in full mode;
• There could be a driver failure/conflict in the system. This often happens with USB drivers, TV tuner drivers, audio drivers, etc.;
• The keyboard drivers themselves may have been damaged.

- programs for working with drivers: search, update, removal:

5) Acidification of the keyboard cable contacts // damage to the cable

If the previous steps did not help, and the laptop keyboard also does not respond to any of your presses, I recommend checking the cable. The following usually happens to him:

1. if you disassembled the laptop and disconnected/connected the keyboard, it is quite possible that the cable could simply not be inserted tightly into the socket. If this is the case, try reconnecting the keyboard;
2. it is also often damaged when the laptop is not carefully disassembled (the wires in the cable are quite thin and can be broken with one careless movement);
3. the contacts of the cable, or the socket in which it “sits” could oxidize over time and not give good contact. Try to gently wipe them with an eraser (as a rule, the contacts begin to become lighter even by eye, which means you have removed the oxidized coating).

IMPORTANT! On some laptop models, it is far from easy to remove the keyboard: to do this, you may sometimes need to disassemble the entire device to the ground! In general, it is usually enough to unfasten several latches with a screwdriver (see photo above) and lift the keyboard plane.

By the way, if your laptop is under warranty, use the service center. Your independent disassembly (including disconnecting only the keyboard) will almost certainly cause a refusal of warranty service!

6) Keyboard flooded with liquid

Some experts brought up interesting statistics: every 50th mug over a laptop tips over on it. In this case, it is the keyboard that suffers first of all. By the way, from my own experience I will say that in case of any spill, the keyboard suffers 100%, but the rest of the devices (under it) still have a chance to remain dry: it all depends on the speed of the user’s reaction after the incident, and the amount of liquid spilled.

In general, liquid is different. Liquids containing salt or sugar are especially dangerous for iron: tea, juice, lemonade, etc. When such a liquid gets on the contacts and metal parts of the boards, the process of oxidation and corrosion begins, which destroys (in some cases not immediately, but surely) iron.

What to do if your laptop is flooded:

1. turn off the laptop: you can immediately disconnect the power supply and remove the battery as soon as possible (the sooner the better);
2. then turn the device over so that liquid begins to flow out of it;
3. dry the device for several days (before this, the device simply will not dry). Do not use hair dryers, heaters, or other similar devices for drying;
4. It is highly advisable to disassemble the device and see how far the liquid has penetrated. In general, of course, if you have never done this yourself, I recommend showing the device to a service center: because even if your device works after drying, the remaining liquid (especially if it was aggressive: juice, beer, tea, etc.) will slowly and surely destroy your iron from the inside, causing corrosion and oxidation.

7) Mechanical damage

In general, according to by and large, there is nothing to break in the keyboard, and as a rule, the breakdown is associated with damage to a specific key (i.e., 1-2 keys will no longer be pressed). Usually, this happens if something fell on the laptop keyboard, or you accidentally touched the device (this, for example, could happen on the road, when moving the device).

In some cases, when the contacts on the keyboard board are damaged (or the button is “clamped”), the keyboard may not respond to pressing other keys and may not behave stable. By the way, you can find out if you have any key pressed if you open some text editor: Word, notepad, etc.

Button "a" is frozen

By the way, if 1-2 keys do not work for you, then you can reassign to others and use the keyboard for a while (or maybe this time will be long?!).

Help! How to reassign one key to another (for those who cannot press a button on the keyboard) -

8) What about the laptop battery?

And the last thing I would like to dwell on in this article. In general, this is quite rare, but I still encountered it on one “no name” Chinese laptop: the keyboard on it stopped working if the battery was discharged and below a certain minimum of 7%, apparently some kind of software was working (I hope such software will not become popular?) .

This concludes my opus, for additions on the topic - thank you in advance. Good luck!

A keyboard is a set of in a certain order keys that allow you to control a particular device, which in our case is a laptop. In addition, the keyboard is one of the main information input devices. Of course, it is not required for tablets and smartphones, but it is impossible to fully use a PC or the same laptop without it.

I have already talked about why maybe. Today we'll talk about the laptop keyboard.

Software glitch

It’s worth starting with the most common problem that you can solve on your own. In this case, I want to look at a software glitch.

What does it look like? You just turn on your laptop after being idle for a while and realize that the keyboard is not working. The first thing you need to do is not to panic, as some people like to do. It is quite possible that the problem is trivial and can be solved in one minute.

The first thing you need to do is restart your laptop. You can do this with your mouse or . We reboot the device or, if desired, turn it off and turn it on again. I assure you that after a reboot, the keyboard will work again at 60%. It's all about something software glitch, which may have occurred during the loading stage of the operating system. If this method helped you, then you don’t even have to read the rest of the article.

If it doesn’t help, then we reboot the device again and as soon as it starts to boot, we try. To do this you need to click on TAB key, and if that doesn’t help, then go to F10 or DEL. One of these options should definitely work. If you managed to do this, then the keyboard physically works and this indicates that the problem is 99% not mechanical.

You need to exit the BIOS and boot the device. Most likely the keyboard won't work, but don't worry, we'll try to get it to work. To do this, it will be necessary at the time when it was in working order. I have already told you how to do this on the pages of the site. Rollback to more early date should help.

In some cases, you can reinstall the operating system, but this, you understand, is not the most pleasant process, along with which, by the way, you can delete important information.

About drivers

Some device problems are directly related to drivers. They may, for example, be completely absent or damaged. In cases with a laptop at the moment very relevant, since almost every component needs to install its own driver.

Find the name of your laptop model on the case, then go to the manufacturer’s website and find drivers for the specified model. Among them there should definitely be drivers for the keyboard. Download them and install them. It is very likely that after this procedure the keyboard will work.

The problem is in the hardware

If none of the above helps, then the problem may be related to the hardware. Most often the loop suffers. As the guys who have already disassembled laptops assure, getting to the cable is not a problem, and besides, you can find manuals on the Internet on how to do this. But before you start disassembling your device, remember whether it is covered by warranty. If yes, then you can’t disassemble it! Take the laptop to the store where you bought it along with the receipt and give it for repair (free, of course). In some cases, it is easier for stores to exchange a laptop for a new one rather than repair it.

Let's say that you disassembled the case and got to the cable. What's next? And then you need to carefully inspect it for oxidation or damage. If there are no external signs of damage, then wipe it with an eraser. I do not recommend using alcohol or other liquids, as this can have a detrimental effect on the performance of the cable.

Assemble the laptop, turn it on and check the keyboard.

Dirt and dust

In no case do we forget about dirt and dust, which really like to accumulate under the keys. Oddly enough, the keyboard may not work precisely for this reason. What to do? As one option, you can remove all the keys (some models allow you to do this easily), remove all the dirt and wipe the contacts with an eraser. If it is impossible to carry out this procedure, then you will have to disassemble the device to get to the keyboard, and this is not so easy to do, since you will have to disassemble a good half of the laptop.

If the keyboard does not work due to spilled liquid

To be honest, the laptop seems to attract liquids to itself, because almost every one of us who has this device, invariably spilled one liquid or another on him. If for normal computer keyboard This most often ends asymptomatically, but for a laptop this is almost a fatal case.

If you spill something on the keyboard, you urgently need to turn off the laptop, remove the battery from it and turn the gadget over so that the liquid flows out of it.

Afterwards you need to disassemble the device. Whether it's worth doing this if it's under warranty is up to you to decide, but it's definitely not warranty case, so no one will repair your laptop for free.

If you do disassemble the device, then place it in a dry place. It is best to dry at room temperature without using “air” equipment in the form of a hairdryer. You need to dry the laptop for at least one to two weeks - be patient. Only after this can you assemble it and turn it on.

Mechanical problems

Mechanical problems are usually caused by the laptop being dropped or something heavy falling on it. In this case, one or several buttons may not work. Less often - the entire keyboard. Most likely, only replacing it will help, and doing it yourself is not so easy, so I recommend turning to a specialized service for help.

The same applies to those cases when the keyboard does not show any signs of life at all, no matter what you do with it.
