When once again you turn on your laptop and the keyboard suddenly stops working - this looks like a serious problem. After all, on such a technique, in contrast to desktop computers, all components are connected together, they are not so easy to turn off or change.
First of all, you need to decide: the entire input panel or individual keys do not work
Therefore, before getting rid of the failed component, we should find out: why does the keyboard on the laptop not work? There are several answers to this question and there are many options for solving a similar problem. Let's learn about them so that we can try to figure out the problem and fix it ourselves.
Why do we immediately pay attention to external problems? Because one of the most common causes of a non-working keyboard on a laptop is dirt, dust or liquid, and also problems with the cable, which will be discussed a little later. Naturally, if you poured a cup of coffee on the keys, you will immediately guess why the device stopped working.
If liquid gets in, you need to take immediate action: unplug the device from power, disconnect the battery and turn the laptop over so that the liquid flows out. Then try disassembling the device, put it in a dry place to dry. By the way, this process takes quite a long time, so you will have to wait a week or even two until all the components return to normal. Only after that you will know whether your laptop is still working or not.
Even if you haven’t spilled or spilled anything on the keyboard, over time, dust, dirt particles, and other things accumulate under its buttons, which can disable the device.
The only sure way out of the situation is to check the cleanliness of the laptop inside, clean the keyboard. To do this, follow these guidelines:
- Disconnect the input device from the laptop (look for the instructions that came with the technique to learn how to do this). Most often, this element is attached to the latches that are located on top of both sides of it - pry them off, after which you can remove the keyboard. If they are missing, most likely you will have to open the laptop case.
- Disconnect the cable by moving the black frame on top, check the contacts for damage. If you notice that something is wrong, this is the reason why the input tool does not work.
- If everything is in order with the cable, wipe it along with the keys with an eraser. The contacts of the loop can be wiped with a cotton swab lightly moistened with alcohol.
- After cleaning the part, install it in starting position, check the functionality.
Checking if the keyboard is enabled
Why are the buttons on the laptop keyboard not working? In the case when you are sure that it is safe and sound, it is worth checking it through the system and find out if this equipment is turned on.
No matter how strange it may seem, many can accidentally turn it off without noticing it. If the buttons on the laptop do not work for you - exactly the part where the numbers are located, you just need to hold down the Fn + Num Lock combination.
Did not help? Then it's worth checking why the keyboard does not work on Windows laptop- it is likely that this is just a system problem.
Checking the system for problems
To check if the keyboard has failed completely or if it does not function only when Windows, do the following:
- If in a safe Windows mode the input device is working - it means that there are problems with the drivers in the work of the software, they should be reinstalled.
- If there is no response in this mode, but the keyboard functions in the BIOS, then the problem lies in the system itself - apparently, you will have to change it.
Reinstalling drivers
So, if you have determined that the keyboard and buttons do not work only in software, and they react to touches in this way, you should reinstall the drivers so that it resumes its functioning.
To do this, follow these guidelines:
- Load the laptop into normal mode Windows to find and download drivers.
- To enter the name of your equipment, prompt in search line without keys, use on-screen keyboard- it is located in the "Start" menu, "Accessibility" section.
- Another input method is by connecting another keyboard via USB, if available.
- To download the appropriate drivers, use the search by specifying the name of your component, or install a utility on Windows that will automatically determine which drivers you need. By the way, similar applications can independently download and install software for a separate component, the most popular of them are Slim Drivers, driver pack solution.
In the case when the installation of the drivers did not bring the desired result, try changing Windows to a newer version.
If all the above tips did not help you, most likely the keyboard is really out of order. Contact specialists who can check it and make sure that it is not working. In this case, you will have to buy and install a new component for the laptop (in principle, you can do it yourself).
Now you will know what to do if the keyboard does not work, you can check it yourself and try to troubleshoot.
Why the keyboard does not work: the main causes, symptoms, ways to fix it.
Keyboard failure symptoms
To fix the problem, you need to establish its cause, which means, to figure out why the keyboard on the laptop does not work: due to mechanical impact or spilled liquid, after visiting questionable sites or installing new software. Or maybe the malfunctions began to appear suddenly, without any reason. .
Also should be checked individual buttons on the keyboard do not work or it is completely out of order, and if so, has it stopped working in operating system Or in the BIOS too.
Symptoms of a broken keyboard:
spilled liquid
Water, tea, coffee, soup, alcohol got on the keyboard
If you spill any liquid on the keyboard, switch off immediately laptop: by holding the power button for a few seconds or simply removing the battery. At the same time, try to hold it so that the liquid does not seep under the keyboard, inside the computer. This may cause a malfunction of the motherboard and other components. 
After turning off, blot the keyboard with a dry cloth and disconnect it from the laptop. This is done quite simply: it is enough to press something thin on the latches located above or on the sides Their location varies depending on the manufacturer and laptop model..
be careful: a thin cable connects the keyboard to the computer, try not to damage it with an awkward movement. Now you need to wipe the keyboard with an alcohol wipe and leave to dry. You can speed up this process with a hair dryer, but only with cold air.
When the keyboard and laptop are completely dry, put it back in and try turning it on. There is a possibility that now everything will become as before, however, if any malfunctions appear, there is only one way out: replacement with a new one. If the laptop has stopped turning on at all or is unstable, feel free to take it to the workshop. With such breakdowns, a simple user cannot cope on his own.
Some buttons on the keyboard do not work
Keys do not respond to pressing, or print the wrong characters
If without visible reasons some buttons on the keyboard do not work, while others continue to operate, then you should check, firstly, if you have Num Lock turned off. If this is the problem, then the numbers are on the right 
on the keyboard will not work, instead the computer will see the arrows .
Find to the left of them (in the upper right part of the keyboard) the "Num Lock" button and press it. On some laptop models, you need to press one of the hot keys (F3, F11, etc.) along with the function (fn) key.
If a other buttons stopped working, check to see if dust has accumulated under them, which prevents them from being pressed. AT this case you should either blow the keyboard thoroughly with a special can that can be bought at the store, or remove the keys by gently prying them with something thin (for example, a screwdriver) and wipe the keyboard manually.
All keyboard not working
None of the keyboard keys respond to pressing.
If for no apparent reason the keyboard on the laptop does not work at all, try rebooting it and entering the BIOS. If before Windows boot the keyboard works, which means that the problem is in the system, and you do not have to spend money on a replacement.
Most likely, your computer got a virus that removed or damaged the corresponding driver, which was the reason why the keyboard does not work. Perform a full scan with your antivirus, and when you finish treatment, update the keyboard driver manually by installing it from the disk that came with the laptop, 
or automatically: by allowing the system to download it from the Internet.
In the first case, you just need to insert the disc into the drive and follow the instructions of the installer. In the second - right-click on the shortcut "Computer", select "Properties", in the window that opens in the left upper corner click on "device manager". In the manager, find the line "Keyboard", open it and you will see the corresponding device. Double-click on it with the left mouse button, or right-click and select the "Properties" option. In the new window, open the Driver tab and click Update.
If this does not help (no virus was found or the system did not find a more suitable driver, and the keyboard still does not work), you should try to restore or reinstall Windows.
In case even Keyboard not working in BIOS on a laptop, the easiest way is to take it to the workshop, especially if you have never repaired computers yourself and have no idea how this is done. Not only because by acting randomly, you can damage your laptop even more, but also because not every store can find exactly the keyboard that your laptop needs. In our workshop, we will select the necessary device ourselves and install it correctly.
However, if along with the keyboard you have touchpad not working and USB inputs, then be prepared for the worst: this is a clear sign of a motherboard malfunction. Its repair or replacement requires much more time and money, and here you certainly cannot do without the help of professionals.
Most laptop users face a variety of problems that make it difficult to work with a computer. Alone problems can be solved independently without certain knowledge and skills, while others, on the contrary, can be resolved subject to the availability of certain skills. In this case, we will find out why the laptop keyboard does not work. And if the keyboard on the laptop does not work, what should I do?
As in any desktop computer with the Windows operating system, problems with the functionality of the laptop may appear at the most inopportune moment. To solve the problem working with a laptop is a little more difficult than troubleshooting the keyboard of such a computer. AT regular computer this element, if necessary, can be easily disconnected or replaced in extreme cases with a new one. With an hp laptop, such manipulations cannot be performed. Here the monitor and keyboard are one.
And it is possible to solve such a problem with the operation of an hp laptop. The main thing is to know exactly why the keyboard stopped working, and how to fix it correctly. problems that have arisen. Let's turn our attention to several common causes of broken keyboards on laptops. After discussing each reason, we will look at how to fix the situation.
Loop wire oxidation
In some cases, oxidation of the loop wires may occur. If the mouse and touchpad work without interruption, check the condition of the cable. To do this, you have to disassemble the laptop case. You can read about how the case is disassembled on the website of the manufacturer of your device. After you have properly disassembled the case, pull out the cable. Next, it is necessary study in detail. Check the cable for obvious damage, signs of short circuit, oxidation. It's possible that your laptop's cable just came loose. This may have happened when moving the computer.
If there are no damages or malfunctions on the cable, we recommend that before returning to the case (and before Windows startup) wipe it with cotton wool with alcohol. Then the loop can be put in place. However, the housing should be fully assembled only after alcohol dries well.
When you assemble the laptop, we advise you to turn it on and test the keyboard again. Run Windows system. If it worked properly, as before - did you manage to fix the problem.
Battery
Sometimes problems in the operation of this element Asus laptop may arise due to incorrect work battery. Problems occur both when a Windows laptop is connected to the network, and when it is discharged. In such cases, due to communication with the battery, the keyboard simply stops working. Solving the problem is very simple. You need to remove the battery and without it connect the laptop to the network. If the keyboard began to work in the usual mode - battery problems. In some situations, batteries need to be replaced.
Motherboard
In some cases, the failure of such an important element of the laptop is closely related to the occurrence of malfunctions. The successful functioning of the motherboard is a guarantee of the successful operation of not only the keyboard, but also Wi-Fi and even USB ports.
If the failure is related to motherboard, serious action needs to be taken. You cannot correct the situation on your own. You need to seek help from service center. In the center, specialists will try to repair your keyboard (and motherboard computer). But there are times when even experienced professionals are powerless against breakage. In such circumstances, the owner will have to buy a new computer.
Drivers
The operation of computer equipment is constantly monitored by special programs. Such special programs are called drivers. However, these programs are as imperfect as the electronic device itself. Therefore, at times drivers may fail. In some situations, this happens after it has been updated. How to be in that case?
To identify the problem with the drivers, you should enter the BIOS. This system can only be accessed using the keyboard. You won't be able to log in with the mouse. If the control arrows work in this system, the cause of the malfunction lies in the previously installed driver. To further confirm your assumptions, turn on the operating system in safe mode. The keyboard should work properly in this mode. If the keyboard in safe mode works without any interruptions, this proves once again that everything problems come from drivers.
What to do with a faulty driver? You need to download a new, working driver for your electronic device. New driver must match your operating system. Thus, it is possible to adjust the operation of the keyboard.
Another of the most common reasons for interruptions in the operation of the keyboard is the ingress of liquid on its surface. This can happen if there was tea or coffee next to the laptop. When working at a computer, you can accidentally push the cup with your hand and all the liquid often gets on the computer. In such cases, it is necessary to act quickly and clearly. Especially if the spilled liquid was tea with sugar or lemonade. Here's what to do first:
Presence of dust or dirt
Things as simple as dirt or dust can interfere with the normal operation of a laptop. Dust is not easy to deal with. You have to disassemble the keyboard. Then, using cotton wool and alcohol, gently wipe the blockages and those places where dust has accumulated. When the laptop is dry, assemble the keyboard and test the keyboard.
When all buttons don't work
In some cases, individual buttons on the keyboard may stop working. In others, the entire keyboard may be faulty. This makes it impossible to print. Why? All problems with the keyboard appear due to a virus that got into the driver (and the Windows system). A virus can remove or corrupt drivers. The virus must be fought. It needs to be removed. You can do this in two ways:
- run a full scan of your computer installed antivirus. The scan should detect viruses and destroy them;
- if the check does not help, you will have to update the driver. To do this, run the following commands:
- click on the shortcut "Computer";
- right-click select "Properties" ==>> "Device Manager";
- then find the line "Keyboard";
- then select the "Properties"==>>"Driver"==>>"Update" option.
If the keyboard does not work after updating the driver, you may need to update the entire operating system.
If your keyboard has stopped working, it does not mean that the entire laptop is broken. Quite often, the problem can still be solved:
- Open Device Manager on your computer. Click on the "Keyboards" sub-item and check if the keyboard is activated.
- Another possible cause the problem is the driver, which maybe you should update. To do this, download the appropriate software from the manufacturer's website and install it. Or update the driver through the "Device Manager", specifying the location of the downloaded software.
- Sometimes a simple restart of the laptop can help. Turn off the laptop, remove the battery and unplug the power cord. Then press the power button several times, then connect all of the above components back. Try turning your laptop back on.
- If water gets into the keyboard, the malfunction can be serious. In this case, seek help from specialists.
If problems with the keyboard could not be resolved, you can connect an external one. For those who actively use the keys (for example, gamers), we advise you to pay attention to game models- as a rule, they have a large resource. The cost of gaming keyboards - from 800 rubles. Here are just a couple of suitable models.
Sometimes users encounter such a problem that part of the keyboard on their laptop does not work for them. In principle, it happens that the entire keyboard does not work at once, but then, most likely, it just needs to be replaced. But if only a part of the buttons ceases to function, everything is somewhat more complicated.
We will consider everything that can be done in this case on our own, without the involvement of specialists.
Simple ways to solve the problem
It is not always necessary to do something complicated in order to restore the functionality of a part of the keyboard. Often the problem is solved quite simply. So from the very beginning, do this:
1.Try pressing the Fn and Num Lock keys. It is possible that pressing one of them blocked some buttons on the keyboard.
2. Hold Fn and press Num Lock, then release both buttons. In some cases, this simple method allows you to start the full operation of the keyboard.
3. Take a brush and go over all the buttons with it. It is possible that some dust has accumulated under one of the buttons. If possible, take a vacuum cleaner as well. On the Internet you can find special vacuum cleaners for small keyboards.

4. Restart your computer. In some cases, there may be some minor bug in the system that prevents certain buttons from working.
In most cases, the problem will be minor and can be fixed with one of these steps. If nothing works, go to the next step.
Fixing a software bug
It is possible that the problem is in the incorrect operation of some programs or services. To check this option and fix the problem, you must do the following:
1. Boot from safe mode without drivers. To do this, restart your computer and immediately start pressing the F8 button. Select "Safe Mode" from the boot options.
Note: Depending on the system configuration, the button for selecting the download mode may differ. So try using all the buttons from F1 to F12 if pressing F8 doesn't help. As a result, a window similar to the one shown in Figure 2 should appear.
System Boot Mode Options
2. Try to create some kind of document and use all the buttons from the keyboard. You need to check not only those buttons that previously refused to work, but also all the rest! If the matter is really software failure, the set of non-working keys may change with each new start.
So, if all the buttons work well, then the problem is really in the operating system. The most likely solution to the problem lies in updating the drivers. It's best to do it in a standard way:
- open the "Start" menu (Windows), then "Control Panel", find "Device Manager" there;
Device Manager in Control Panel
- open the "Keyboards" item;
- usually there is only one keyboard, right-click on it and select "Update drivers ..." (if there are several keyboards, which is very unlikely, do the same with all);
- select " Automatic search…»;
- wait until the drivers are found on the Internet, they will be installed automatically.
Updating drivers in the standard Windows way
You can also download and install DriverPack program solution. It allows you to scan your entire computer for the latest available drivers. If the keyboard has incorrect (roughly speaking "broken") or outdated drivers, you can easily update them. The use of this program is as follows:
- download the program (here is the link);
- install it and run it;
- an automatic scan will occur, after which just click on the "Update all" button.
Driver Pack Solution window
Scan the system with your antivirus and remove any viruses found. Also, you can use special utilities, such as Kaspersky Virus Removal Tool or Malwarebytes Anti-Malware Free.
If updating and scanning your drivers doesn't help, try rolling back your system to a point where everything was working fine.
To do this, you need to do this:
- open the "Start" menu, then "All Programs", "Accessories";
- then go to the “System Tools” section and click on the “System Restore” item;
System Restore item in the Start menu
- in the window that opens, click "Next";
- then select the desired restore point, and they are sorted here by date and time (you need to choose the one that most closely matches the time when everything was fine);
Selecting a restore point for system rollback
- click "Next" and then "Finish".
In principle, you can also reinstall the drivers and roll back the system in cases where the keyboard also does not work correctly in safe mode. But in this case, the likelihood that it will help is very small. Most likely, the problem is already mechanical, not software, and it needs to be solved by physical intervention in the computer device.
Fixing a physical glitch
In this case, you will have to disassemble the keyboard and gradually look at what could have failed there. To do this, follow these steps (it is very important to follow exactly this order in which all actions will be listed below):
1. Turn off the laptop and remove the battery from it.
2. Take a flathead screwdriver and carefully pry out all the latches on the plate that holds the keyboard. If you do not see any latches on your laptop, you should pick up the instructions and read what is written there about the keyboard device and how it is removed. In any case, some attachment mechanisms must be present.
The process of opening the latches of the keyboard plate
The keyboard plate is attached to the laptop itself with a cable. You will see it right away.
3. So, if there are obvious damages on it, you just need to remove the cable and replace it with a new one. To do this, take an old cable, go to the nearest electronics store and buy the same one.
Keyboard cable
4. If the cable is not damaged, it still needs to be removed. At the same time, the train cannot be taken for conductors in any case! You can take only those plastic parts with which it is attached to other parts of the laptop. For clarity, figure 10 shows those parts that can be taken and those that cannot be taken. True, keyboards usually use slightly different cables.
5. In the same place, under the keyboard plate, you can find the microcontroller. Its necessary dry and try to draw out the dust with a vacuum cleaner.
It is quite difficult to explain how to find this very microcontroller. To put it simply, this is exactly the device to which the cable is attached. Just in case, when removing the keyboard, go through all the controllers that you see. Nothing more can be done on your own without special knowledge. Again, if you see obvious damage on the microcontroller, it is better to replace it.
Laptop with keyboard removed
6. If everything is fine with the cable, you will have to disconnect the keys and clean them. Usually, the button can be removed in the standard way - pry with the same flat screwdriver. Start with problem buttons. If you see damage under them, replace the elements with which the button is attached to the laptop.
The process of removing buttons from the keyboard
7. Try using the keyboard again.
If the problem persists, remove all buttons and remove the aluminum plate that is under them. Usually she also has special mounts that are removed quite easily. But under it is hidden a polyethylene board with drawn tracks.
Inspect it for obvious damage - if there is, there are two options: draw new tracks or buy a new board. In any case, go over the board with a vacuum cleaner.
To check the integrity of the tracks, use the tester.

To draw tracks, use a kit for repairing car rear window heating filaments (that's what it's called).
If all else fails, your best bet is to send your computer in for repair.
The video below clearly shows the process of disassembling the laptop keyboard.
