Assembled laptop keyboard does not work. The keyboard does not work on the laptop. What to do? Symptoms of a broken keyboard

A laptop is a compact mobile device that is the best choice for surfing the web, performing work tasks, watching movies, etc. Today we will consider one of the fairly common cases - when the keyboard does not work on a laptop.

In this article, we will consider the main reasons that can affect the inoperability of the keyboard on a laptop, and, accordingly, how to solve them.

Reason 1: factory defect

Let's start with perhaps the simplest reason for the inoperability of the keyboard, when you bought a brand new laptop in the store, brought it home, but when you start the keyboard completely refuses to work. In this case, it is likely that your laptop has a factory defect, therefore, without wasting time, we go with all the complete set of the laptop and a check to the store at the place of purchase, where you must either return the money for the goods, or make an exchange for a working model.

Reason 2: system failure

The next most simple reason for the keyboard inoperability is a system failure. As a result of a system failure, users, without bothering to restart the PC, immediately contact the service center, although the way to solve the problem is extremely simple.

Reboot the system using the mouse (the "Start" - "Restart" button) or hold down the power key on the laptop and hold it until the laptop is suddenly turned off. Then try turning on the laptop and booting normally by checking the keyboard health status.

Reason 3: combustion of the microcircuit

Now let's move on to much more unpleasant reasons for the inoperability of the laptop keyboard. First, be sure to check the status of the USB ports and touchpad. If they do not work, there is nothing left for you to do but contact the service center.

Reason 4: the problem is in the loop

If the keyboard suddenly, for no apparent reason, stopped working, but the USB ports and keyboard continue to function normally on the laptop, the problem is probably in the cable, which could accidentally come off or be damaged (especially if the laptop was opened before).

If you have some experience, open your laptop, we are specifically interested in the keyboard cable. Make sure the cable is free of oxidation and any other types of damage that will require replacement. In simpler cases, the cable could simply move away from the connection connector, and therefore all you have to do is connect the cable and assemble the laptop.

Reason 5: failure

Typically, the hardware laptop keyboard stops working for the most popular reason - it was flooded with liquid. The problem is that if you accidentally spill liquid on the laptop keyboard, it seems that everything has dried out, after that the keyboard may still work normally for a while, but as a result, the day may still come when it will completely refuse to function.

As a temporary solution to the problem, connect a separate keyboard. But still, you should not postpone a visit to the service center, where they can diagnose the cause of the breakdown and, quite possibly, return your laptop to normal performance.

Reason 6: drivers

We are smoothly moving from hardware causes of keyboard problems to software ones.

If you are sure that the keyboard could not fail in any way due to hardware reasons, it is high time to check for the presence of keyboard drivers. To do this, open the menu "Control Panel" , set the mode in the upper right corner of the screen "Small icons" and then go to section "System" .

In the left pane of the window, go to the section "Device Manager" .

In the window that opens, expand the item "Keyboards" and check if this item contains the name of your keyboard. If your item has a yellow icon with exclamation mark or there is no keyboard name at all, respectively, the problem is really in the drivers, so your next task is to install drivers for your laptop keyboard.

How and where to find required drivers, previously described on our website.

After installing the drivers, be sure to restart your computer.

Reason 7: computer viruses

If the problem is not in the drivers, you should suspect the action of viruses on the computer. To check the likelihood of this reason, be sure to perform a deep scan on your computer using your antivirus or a special healing utility Dr.Web CureIt.

After removing all viruses, be sure to restart your computer.

Reason 8: features of your laptop

Quite a ridiculous move on the part of laptop manufacturers, but it still occurs. The fact is that laptops under Windows control are generally disappointing with long battery life. As a result, some laptop manufacturers have decided to optimize performance by shutting down certain devices when the battery is low.

In this case, try connecting your laptop to the network and testing the keyboard to see if it works. If it works successfully, try to find a utility from the manufacturer on your computer, through which, most likely, you can control such a function.

If you are still at a loss to solve problems related to the inoperability of the laptop keyboard, as a temporary solution, you can use standard application The On-Screen Keyboard, which is available on every Windows computer, or connect a separate USB or Bluetooth keyboard.

Laptop keyboard not working? This is not to say that this is a typical situation for modern technology, this is a rather rare breakdown of laptops. And if in the case of a PC it is not even possible to understand the cause of the breakdown, simply replacing one keyboard with another, then in the case of a laptop, things are much more complicated, because its keyboard is an integral part of a single integral design. What are the reasons for the breakdown of the laptop keyboard, what consequences can be expected, how to get out of the situation when you urgently need to enter text on a laptop with a non-working one - we will consider all these questions below.

1. Is there a blacklist of laptop models prone to keyboard breakage?

Before proceeding to the direct consideration of the problem of a laptop keyboard breakdown itself, a few words about whether it is possible to prevent the occurrence of such a situation. Is there such a blacklist of laptops - specific models, products of a particular manufacturer, which in practice would prove their tendency to breakdown of the keyboard? No. On the market computer technology there are no such models for which, in practice, a tendency to this particular breakdown would be observed. Any laptop keyboard from any manufacturer can fail. And this applies to how flagship models, and budget.

2. Possible reasons for laptop keyboard failure

Before taking your laptop to a service center, you can try to figure out for yourself why the laptop keyboard does not work. And if it is a software glitch or keyboard loop issues, your attempts may be successful and you will save money on the services of the service center. So let's get started.

2.1. Software glitch

The reason for the failure of the laptop keyboard may be due to errors in the operation of the operating room itself Windows systems... Typically, this happens in the event of a driver failure. You can check this in the BIOS. To exit to BIOS, restart the laptop and hold down the Del key. In some laptop models, the F1 or F2 buttons may be used to exit the BIOS. This point can be clarified in the instructions of the laptop manufacturer. If in the very BIOS keyboard works, you can boot Windows in safe mode to further test if the keyboard works without drivers and with minimal system services.

You can get into the safe mode of Windows XP, Vista, 7 by pressing the F8 key, which must be held down while the system boots. The boot mode selection menu will appear, where you must select to boot in safe mode without drivers. In the case of Windows 8 / 8.1, the exit to the safe mode of the system is somewhat different, some preliminary system settings... Walk the path:

"Control Panel" - "Administration" - "System Configuration".

In the "Downloads" tab, set the value "Safe Mode", click "Apply", "OK" and reboot. After rebooting, you will be taken to Safe Mode.

You can return the settings to their former state in the same way, by removing the "Safe Mode" value.

So, you've entered Windows Safe Mode. Check the laptop keyboard is working. If the laptop keyboard works in safe mode, then the problem lies in the operation of the drivers. If the keyboard is safe Windows mode does not work, while the BIOS responds to data input, most likely the problem is in the operating system.

After returning to normal mode Windows work carry out work on installing or updating drivers.

Download and install driverpack. This is a special type software, designed to select drivers for specific hardware components computer device... Having scanned the laptop and determined the drivers necessary for installation, the driverpacks automatically remove their installers from their database and carry out the installation. Driverpacks on the Internet can be found in the image of a DVD with the available driver base, but it is much easier to quickly download and install the driverpack software client, which after scanning will download from the Internet only the necessary drivers in the most recent, up-to-date version.

DriverPack Solution, Slim Drivers- the client programs of these drayverpak on the Internet can be downloaded absolutely free of charge. These are the two leaders among drayverpacks, they are popular among users because of the free and regularly updated database of drivers. Scan the laptop using driverpack and install (or update) the drivers indicated by the program.

You can install or update drivers without resorting to driverpacks. Download them manually from the official website of the manufacturer of your laptop model.

If working on installing or updating laptop drivers does not solve the problem with the keyboard not working, you can try reinstalling Windows itself. For example, Windows XP - today it is already an outdated operating system, and possibly with Windows installation 7 or 8 / 8.1, the keyboard not working problem will go away.

2.2. Pressed or oxidized contacts of the keyboard loop

If you have been using a laptop for a long time, it is possible that the problem of the non-working keyboard lies in the oxidized or wrung-out contacts of its cable. To test this option and try to solve the problem, the laptop will have to be disassembled. If this is the first time you disassemble a laptop on your own, use its manufacturer's instructions. Instructions for many device models can be downloaded on the Internet in electronic form, in particular, on the official website of the same manufacturer. You can also watch video tutorials on how to properly disassemble a laptop on YouTube or other resources.

Having reached the keyboard cable, disconnect it by pushing it out of the connector and carefully examine it. If you see obvious damage during inspection, therefore, this is the reason for the non-working laptop keyboard. And you can solve it by replacing the train.

If everything is in order with the keyboard cable, wipe its contacts with an ear stick moistened with alcohol, or use a regular eraser. After cleaning, plug the keyboard cable back in and test.

2.3. Failure of the microcontroller or liquid spilled on the laptop

If the reason for the non-working laptop keyboard is a burned-out microcontroller or spilled liquid, then you cannot do without the services of a service center. It is impossible to thoroughly determine which hardware components of the laptop are out of order, and you cannot re-solder them at home (of course, if you are not an expert).

During a spillage of liquid on a laptop, if it gets on the board, over time it leads to oxidation of the contacts. As a result, the keyboard is completely out of order. If you accidentally spill liquid on your laptop, unplug it immediately, remove the battery and dry your hair with a hair dryer. If the hair dryer model has a cold air button, use only cold air. This is necessary in order, if not to prevent, then at least to slow down the process of oxidation of contacts, microcircuits and boards.

3. You urgently need to enter text on a laptop with a non-working keyboard - what to do?

The laptop keyboard does not work, and you urgently need to send a message. Or even to download the same driver pack from the Internet, you need to enter its name into the search engine. How to be in such a situation?

3.1. Windows virtual keyboard

Windows OS has built-in functionality that emulates a physical keyboard - this is the standard On-Screen Keyboard application. Click the "Start" button, select " Special abilities", And here -" On-screen keyboard ".

Click the desired keys to enter characters. On-screen Windows keyboard implemented the "Options" button, when you press it, you can make some settings to customize the application for yourself.

OS Windows 8 / 8.1, except standard application On-Screen Keyboard has an alternative in a slightly different format. This is a dedicated touch keyboard for tablets and laptops with touch screen- a smoothly sliding window with large buttons so that it is convenient to get on them with your finger. If your laptop is running Windows 8 / 8.1, on the panel Windows tasks bring up the content menu and select "Properties".

The "Properties of the taskbar" menu will open, go to the "Toolbars" tab and check the box next to the "Touch keyboard" option.

3.2. USB keyboard

When it comes to typing a speed test, of course, you can't do a lot with the on-screen keyboard. A physical USB keyboard can be connected via the laptop's USB port.

3.3. Bluetooth keyboard

Bluetooth keyboard - a physical keyboard that can be connected to a laptop via bluetooth module... Almost all modern laptop models are equipped with this module.

Over the short, and maybe long life of your laptop, you could come across several reasons for the failure of various hardware nodes. Let's consider several reasons why laptop keyboard malfunctions (keyboard stopped working) and how to fix it.

Driver problem

In most cases, this problem is solved as follows: upon reboot, we go into the BIOS of the device. Depending on which device model you have, you will need to press the DEL or F2 key. If you manage to enter the BIOS, you will see a blue or gray screen.

Try using the arrows on the keyboard to navigate the menu. When you exit, press F10 and the Y button, then Enter. If everything worked out, then before booting Windows 7 or XP, hold down the F8 key and select "Safe Mode".

This is necessary so that unnecessary services are not loaded, which can interfere with the operation of the keyboard. If the device is running Windows 8, then we will need to do one manipulation in order to boot into "Safe Mode".
To do this, go to Start Control Panel Administration System Configuration, go to the Boot tab and put a tick on Safe Mode, then click the Apply button and restart the computer.

If, after doing all these manipulations, the keyboard works, then the problem was in incorrect work drivers. That is, a normal software failure. If the device works in BIOS, but not in the operating system, then most likely the problem lies in the operating system itself. It is advisable to reinstall Windows.

If you have windows 8 - you have the opportunity to use onscreen keyboard.

To enter characters with faulty device Windows developers have come up with On-Screen Keyboard. To use it, you need to go to Start Accessibility, then select On-Screen Keyboard and thus launch the keyboard, it will appear on your screen. With the mouse, you will be able to enter characters. You may need this option for solving the problem in any of the extreme cases (for example, the deadlines for the delivery of some documents are on fire).

Problem with the keyboard loop.

This problem is related to the age of the laptop and the frequency of its use, as well as, of course, the "habitat". If the laptop operates in a dusty atmosphere and has not been cleaned for a long time internal parts, then it may be necessary to further disassemble the device and thoroughly clean all contacts and connectors. internal devices... Having disassembled the device, pay attention to the keyboard connection cable itself and to the connector, if the latter is clogged with dust, carefully clean it. If the problem is with the loop, then you should contact the service center of the manufacturer of your device, where the breakdown will be fixed.

Flooded keyboard

AND last problem spilled liquid (tea or coffee, for example) on the keyboard. In this case, the keyboard microcontroller may be damaged and you will have to contact the service center.

Consider the option when the controller most likely remained in working condition... We disassemble our laptop, disconnect the battery, remove bottom panel and thoroughly dry the motherboard and keyboard cable contacts with a hairdryer. After complete drying, we assemble the device and try to work.

Hello dear readers of my blog! Today we will talk about why the keyboard on a laptop does not work, what to do in this situation, what may be the causes of the problems. I will cover the most common problems and their solutions. If none of the following list still helps you, then it seems that you cannot do without the services of a master here. But let's not worry ahead of time and begin to consider possible problems.

I'll start with the simplest option. If you bought a laptop quite recently and there is still a guarantee for it, then it makes sense to use it now. Perhaps you have a factory defect and therefore the keyboard on the laptop does not work. Sometimes users think that it is better to contact their person, who, in their opinion, is better versed in the computer than someone else. This is not necessary, if your person does not make a computer or laptop and at the same time breaks the seals on it, then you will not be able to apply for a guarantee, you will have to pay for it.

When the keyboard works properly, but for some reason you cannot work with it in the system itself, then a failure may have occurred. This is one of the most common problems, because of which people immediately run to specialists, and they then rip off huge amounts of money from them. It is very easy to check whether it is a failure or not.

Attention! If the laptop is flooded with liquid, then do not follow the instructions below, read the entire article!

It is enough to reboot the laptop and, when it is turned on, enter the BIOS. To do this, press the Delete or F2 key when turning it on. If you see a window with English letters on a blue or gray background, then you have entered the BIOS.

The computer recognized the button presses, which means that now we just need to exit the BIOS and reboot the system. After that, everything should work. If your keyboard did not work, but then you were able to enter the BIOS, it means that the keyboard is working. We need to figure it out further.

If you failed to enter the BIOS, then we will have to deal with a relatively difficult task, namely, disassembling the laptop. Do not worry ahead of time, because in fact it is not that difficult. For your safety net, it is better to find instructions, because different models understand in different ways. In Google, we type the model of our laptop and assign the words: "How to disassemble" or vice versa "Assembly diagram". Be sure you will find what you are looking for. Carefully, strictly following the instructions, we take out the keyboard. If this is not in the diagram, make a request on how to disassemble the keyboard, here I will not dwell in detail. Once the procedure is complete, carefully examine the train. It is possible that it is he who is to blame for this problem.

If he was in perfect order, then very carefully vacuum the whole thing from dust and debris, this can also be the cause of the malfunction. I recently witnessed a very dirty keyboard and the end result - it didn't work. When the sanitary procedures were done, everything worked 😉.

Another possible problem can be considered the fact that you are very long time kept the laptop in the heat, for example, in the summer, and then brought it to an air-conditioned office. Or, conversely, from a cold environment to a hot one. In this case, the contacts, to put it mildly, can temporarily jam, but keyword- temporarily. If you brought it home from a cold street, be sure to let the laptop warm up, so to speak. In this situation, never turn on the laptop, let its components warm to room temperature in the off state for half an hour. Everything will work.

By the way, when you are sitting at home, working on a laptop and decided to go out with it in the winter, then turn it off in advance 15 minutes before going out.

Users often enjoy drinking tea or coffee directly over their laptop. In this case, I can give some recommendations. Turn off the laptop, if it turns off for a long time, then we do an emergency shutdown, remove the battery, turn it over and drain the remaining liquid. Be sure to disconnect the power from the laptop.

To repair the keyboard, as I said above, you need to remove and clean it. But it is possible that the track or part of the tracks can be damaged, in which case they will need to be restored. On this occasion, you can watch a video, for example, on YouTube, but users who know little about this are better off not meddling.

If the liquid gets not only on the keyboard, but also on the motherboard, then everything can be more serious here, and in this situation, you can invest a lot of money in repairing a laptop.

By the way, the same situation is with cell phones... Recently, my wife bought her phone for a while, accidentally dropped it into the water. After which the buttons did not react, and after a while nothing was visible, only a white screen was shown. In this case, you can dry it a LITTLE with a hair dryer, but not for long, then wait 5-8 hours, after which the phone can work. If there is no hair dryer, then put it on the windowsill where there is the sun and let it lie down. If you bathed it in winter, you can put it under the battery, don't put it directly on it!

What to do for those who have not been helped by any of my advice. Unfortunately, luck is not on your side today and you have two options. Either we completely change the keyboard (it is not recommended to do it yourself for those who do not understand this at all), or you still have to carry a laptop with a faulty keyboard to a service center, and there professionals will conduct detailed diagnostics and identify the problem. But I sincerely hope that many of you will never finish reading the article to this point, because you will find a solution to your problem from the list above.

As you understand, you need to be patient to figure out the problem and find out why the keyboard on the laptop does not work.

I have everything, I wish you good luck and see you soon!

Hello.

The laptop keyboard stops working as often as the keyboard on a regular desktop computer. True, if the keyboard of an ordinary PC can be easily and quickly disconnected and a new one connected (at least for testing), then with a laptop it is somewhat more difficult ...

In general, there are many reasons why the keyboard on a laptop does not work. In this short article, I want to take a look at the most common ones.

1. Fault setting ...

If the keyboard suddenly stops working without any serious reasons(for example, dropping a device) - the first thing I recommend doing is to check whether it "does not work completely" or only in Windows?

The fact is that some viruses and especially drivers (for example, on Bluetooth), if they fail, can disable the touchpad and keyboard. Most quick way check it out - go to the BIOS.

How to enter BIOS (enter keys) -

If you entered the BIOS and the keys work there - this is most likely the cause of the malfunction in Windows. In this case, you can try booting into Safe Mode (or with help) and check if the keyboard works. If it works - the reason is in Windows 99.99%! In this case, one of the most simple options solutions to the problem are reinstalling windows(or search for a faulty driver, you can find out in device manager).

Device Manager: no drivers available.

If you are not logged into BIOS - the keyboard does not work completely and this is not a driver or Windows crash. In this case, I recommend trying to connect to USB port mouse and keyboard and see how they work. If they also do not work, the problem may be in the burnt chip on the mat. board (you can't do without a service center).

2. The problem with the drivers.

As I said above, this is a very popular reason for keyboard failure. It occurs in most cases due to USB and Bluetooth drivers. To solve it: you can roll back the system (restore) if there are restore checkpoints; remove faulty drivers; reinstall Windows.

1. System Restore

Go to the control panel and start recovery (in Windows 8/7: Control Panel \ All Control Panel Items \ Recovery).

2. Removing / installing drivers

I have some good articles about this on my blog. I will give links to them here. In general, you need to: remove completely faulty drivers, and then download the drivers from the official website of the device manufacturer.

3. Reinstall Windows

Reinstalling Windows 7 instead of Windows 8:

3. Is the battery OK ...

The fact is that some laptop models, due to the specific design, may not work correctly with the battery. Those. if it is connected to a laptop and is discharged (or simply does not work), then the keyboard may stop working. This can be easily verified by disconnecting the laptop battery and plugging it in.

Notebook: bottom view (green arrow points to a place under the battery).

4. Is the train ok ...

If the touchpad on the laptop works, the connected keyboard and mouse to USB also work - maybe it's a cable: it could just move away (either due to loose contact, or when moving the device). Also, the cable from the keyboard could be incorrectly connected if you recently removed the keyboard (for example, when cleaning the laptop, and indeed when disassembling the device).

A fracture (bend) of the train is also not excluded (this may be due to bad design laptop.

Laptop keyboard: ribbon cable for connecting to the device.

Important! To remove * the keyboard from the laptop, pay attention to its outline: there will be small latches on the top and bottom (sometimes on the left and right) sides. It is convenient to pry them off with a regular screwdriver, and then carefully remove the keyboard. You need to act slowly, the train in some models is thin enough and damaging it is a very simple matter. If you have never disassembled your laptop before, you should probably contact a service center.

* By the way, in some laptop models it is not so easy to remove the keyboard, you must first unscrew the additional mount.

5. If several keys do not work

If dust (or small particles, crumbs) gets under the keys, they may stop working. Enough common reason inoperability individual keys on keyboard. The fight against this scourge is simple: to clean the dust and not take the device to the kitchen (as many people like to do ...).

6. Flooded keyboard

If a liquid containing sugar or salt (for example, tea or lemonade, juice) is spilled on the keyboard surface, the process of corrosion will begin. By the way, because of this, not only the keyboard may fail, but also motherboard and other laptop devices.

Actions when flooding:

Disconnect from the power supply completely and as quickly as possible (remove the battery from the device case, disconnect the power supply);
Turn the device over: so that all the liquid flows out;
Do not turn on the device until it is completely dry (usually 1-2 days).
It is advisable to show the device in service center... The fact is that even if the device works after switching on, the corrosion process that could begin is not excluded. And soon, the laptop may fail (especially if "aggressive" liquids have been spilled: coffee or tea with sugar, Coca-Cola, Pepsi, juices, etc.).

6. Interim measures

In my opinion there are 2 effective ways temporary solution to the problem.

1) Connecting an additional keyboard to the USB port (if, of course, they work).

2) Enabling the on-screen keyboard (it will especially help out if 1-2 keys do not work for you, which you need to press from time to time).

How do I enable the onscreen keyboard? Go to " Control Panel \ Accessibility \ Accessibility“Then turn it on.

Good luck!
