Usually, when the keys on your keyboard don't work, it is due to a mechanical failure. If so, the keyboard needs to be replaced. However, sometimes broken keys can be fixed. Some of the remedies are explained in the following sections. Note. Following are the steps to troubleshoot keyboard issues with some keys working.

If the function keys do not work

If the numeric keypad keys do not work

If all else fails, replace the keyboard. If all of the previous suggestions have been completed and one or more keys are still not working, it is likely that the keyboard is defective and needs to be replaced.

Testing the keyboard via BIOS

First of all, see how the keyboard behaves when you turn on the laptop. Try to go to BIOS. When starting the laptop, immediately start pressing the Delete or F2 key (depending on motherboard). If the entrance to the BIOS is completed, then the keyboard is working. You can walk through the BIOS menu and make sure that everything is in order with the keyboard.

There are many factors associated with this issue. So, first restart your laptop and check whether the keyboard is working or not, if not, then follow the tips. Recover Your System: System Restore - The best way solve keyboard software problems. If it doesn't work, then follow the prompts. Check if your drivers are up to date or not. If not, please update your drivers first and then restart and check if your keyboard works.

Causes of laptop keyboard breakage

After updating your keyboard drivers and still your keyboard is not working, then do simple steps... Watch the video below for a better understanding. The above steps work for you if your laptop has a software problem. If your keyboard has a hardware problem, contact a technician or your laptop. If the above steps don't work for you, contact your laptop technician and have them check your laptop for any hardware issues.

Faulty keyboard

If in BIOS keyboard also does not work, that is, the likelihood that it is completely out of order, but not a fact. Think, was it such that the keyboard was poured with tea or beer for a couple of days? And if the keyboard worked in the BIOS, then this is most likely a software malfunction and you need to solve it through Windows.

One moment that you type on your computer keyboard, as usual, suddenly a key is pressed or a character is missing on the screen. Perhaps you have a bunch of keys that suddenly stop working. Laptops and desktop keyboards can stop functioning for a number of reasons, most of which can be fixed through troubleshooting. Knowing how to fix some keyboard keys that are not working can save you time and money on buying a new keyboard.

Original keyboard

Disconnect and reconnect your computer keyboard, and then restart your computer. Sometimes a bad connection can cause the keys to not work on your keyboard. Update the device driver for your keyboard by going to your keyboard manufacturer's website and then download and install latest driver corresponding to the brand and model number of your keyboard.

Reinstalling drivers

Click on the Computer section and open Properties. Next go to Device Manager.

Find the Keyboards section and delete everything under a clean one.

Align any curved pins you can find using a ballpoint pen carefully. You must replace the keyboard if you see broken pins. Try validating your keys with another application, such as another word processing program.

Disable the standard desktop keyboard, then click on the key that doesn't work. Slide the car key or flat head screwdriver. Screw in a screwdriver or car key until the keyboard pops out. Use a damp cloth, damp cotton swabs or compressed air to remove dust, hair and food crumbs on a turnkey basis. Use only water or rubbing alcohol to moisten cloth and cotton swabs - other cleaners can damage the plastic on your computer.

The driver will be removed! Now restart your laptop and check if the keyboard is working.

System Restore

It happens that some programs or we ourselves messed up in the system, installed something wrong, or, on the contrary, deleted important files and Windows now does not work stably. The keyboard on the laptop may also not work because of this. I suggest doing a system restore!

Place and press down on the key to snap it into place. Repeat this for all keys to clear them underneath if necessary. Turn off your laptop, then use a Phillips screwdriver or knife at a key angle while gently stroking the key. You will hear a click when the key is released.

Remove the key holder remaining on your laptop using a knife or screwdriver at an angle, then push it out with a gentle swirl. Remove the strip by pulling it after insertion with a screwdriver or knife under the panel. Clean cotton swabs or a soft cloth dampened with water or alcohol under the keys of the laptop. You can also use compressed air to remove dust, hair, and other debris.

Open Start - Control Panel... Select the icon display type Small icons and find the Recovery program.

Replace the laptop keys by placing the key lock in the desired position. If you cannot remember the position, copy the other lock position by deleting the other key. Insert the keyboard into the retainer, then place the key on the retainer while pressing down on the key. You should hear a click in place. the laptop onto the space slot, then secure it in place.

If your portable computer will not turn on, it may be damaged and needs to be repaired. For a while, however, the problem isn't with your computer - it's your power source. In other cases, the battery is discharged. Finally, it might just be that your computer is fine, but it just doesn't respond to the power button.

We carry out Launching System Restore.

We select a restore point for about the date when the keyboard worked and click Next.

A rollback will be performed and the laptop will reboot!

Just because you think your computer's battery is charged doesn't mean it really is. It is possible that your plug slipped out of the wall or out of your computer while it was supposed to be charging. On the other hand, many computers don't actually turn off when you turn them off and continue to draw power from the battery.

Fixing a dead battery is easy to do. Connect your computer to a power source, wait a few minutes, and then turn it on. If it works, the problem is with the battery. Sometimes the terminals for your laptop's battery get dusty or dirty and it doesn't make contact. If this happens, your computer won't run on battery power and won't turn on if you don't have one. Remove the battery to fix the problem.

In any case, for now, the text can be typed using virtual keyboard or as it is also called.

Open the search bar and enter a query (or Start - Specialist. possibilities-). Run the found program.

Remove the battery by flipping the computer to open it, and locate the spring-loaded switch that holds it. Hold the switch and lift the battery or slide it out. The terminals will be in a small block somewhere on the battery that matches the metal ribs or contacts on your computer. Use compressed air to clean them and wipe the computer contacts with a soft cloth.

Insert the battery, wait a minute or so, and then try turning on the computer. If your laptop does not start due to a dead battery and the battery does not charge, you can turn off the power. To test the power supply, connect it to your computer and check to see if the battery indicator comes on. If this happens, the power supply may not be a problem.

Now we can type text with it. For example, I opened a notepad, put the mouse cursor and began to click on the letters of the on-screen keyboard with the mouse. Typing went.

You can also do with the Yandex search bar.

Operating system error

If not, make sure your power supply's power cord is tight — sometimes the cord from the wall to the power supply gets loose. If the cord is tight, try a power supply with another compatible computer, or try a different power supply with your computer - they are not that expensive to buy. If you find out that your power supply is the problem, you will have to either buy a new one or replace it under your laptop's warranty.

If your laptop does not respond to a button press or anything else, it may happen that it is locked. Most laptop power doesn't look like a wall switch. It can physically turn off the power, but it also sends commands, including a command to sleep or wake up. Sometimes you need to really restart your computer to get the power button to work.

But I must tell you that not some sites already have their own screen keyboard... On home page Yandex it is to the right of the form.

Click there and such a beautiful keyboard is launched.

Naturally, it will only work on Yandex, to enter a query into the search bar.

Power off your computer and remove it using the above procedure. Hold the power button with your finger for at least 30 seconds, but you can also hold it down if you like. Two minutes is probably more than enough, and five minutes is definitely more than enough. This will eliminate any saved board on your computer.

Release the power button and power on your computer again. You don't need a battery yet. Wait a minute or so, then press and hold the power button to turn it on. Found function keys not working on your laptop? Just follow the verified fixes in this guide.

By the way, Google also has its own screen, so if your keyboard does not work on your laptop, then at least you can find something on the Internet and type text into your notebook.

Connecting a USB keyboard

If it was not possible to restore the keyboard built into the laptop, then you can connect an external one. Yes Yes exactly! Keyboards that are designed for computers will easily fit into laptops as well. The main thing is to choose USB keyboard, because hardly any laptop today has a PS / 2 port. But there is a USB connector on any laptop.

Most laptops have separate hard drives. Visit your laptop manufacturer's website, go to the driver download center and find your laptop model. If you are not tech savvy, we highly recommend using - an extremely useful driver tool. It can help you scan for drivers with problems and update them automatically. It can suggest the latest drivers for you.

Then find your laptop model. How annoying it is when your left button mouse stops working? You change batteries, bang them on your desk a few times, and curse the gods of technology - but it's useless. All you can do to get it working again is restart your computer.

That's all. I hope by some of the options you managed to solve the issue with the keyboard. See you in new lessons!

Sometimes users are faced with such a problem that part of the keyboard on a 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.

If you are in the middle of something and you have a lot open windows, this is very frustrating. You lose concentration and have to spend 10 minutes waiting for everything to end and reboot. It doesn't have to be this way. There are steps you can take to left click again.

With this handy guide, you'll be an expert in no time. It has become the central hub for launching applications and managing your system again. There is no one-time solution. A whole gospel of things could go wrong. Here are a number of fixes that worked for most users.

We will consider everything that can only 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 difficult in order to restore the functionality of a part of the keyboard. Quite often the problem is solved quite simply. So from the beginning, do this:

The application will ask you for new data and username to login. If it still doesn't work, you can skip the first fix. Try copying all user data to a new profile. To complete this process, you will need at least three profiles on your computer.

Fix 3: Remove recently installed apps and drivers

Then you need to run the checker system files... This can take a long time, so be patient. Likewise, automatic program updates may have caused the problem. Uninstall all apps you recently installed, all apps you recently got automatic updates and any apps you no longer use. Restart your computer and check if the problem is resolved.

1.Try pressing the Fn and Num lock... It is possible that pressing one of them blocked some of the 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 keyboard operation.

3. Take a brush and run it over all the buttons. It is quite possible that some kind of dust has accumulated under one of the buttons. Bring a vacuum cleaner if possible. 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 corrected by one of these actions. If all else fails, proceed to the next step.

Fixing a software glitch

It is possible that the problem is wrong work some programs or services. To check this option and fix the problem, you need to do the following:

1. Boot from safe mode without drivers. To do this, restart your computer and immediately start pressing the F8 button. Among the boot options, select "Safe Mode".

Note: Depending on the system configuration, the button for selecting the boot mode may differ. So try using all keys F1 through 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 all the rest! If it really is software glitch, the set of disabled keys may change with each new start.

So, if all the buttons work well, then the problem really is operating system... The most likely solution to the problem lies in updating the drivers. The best way to do this is 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, click on it right click mouse and select the item "Update drivers ..." (if there are several keyboards, which is very unlikely, do the same with all);
select the item " 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 the program DriverPack Solution... It allows you to scan your entire computer for the latest available drivers. If the keyboard has incorrect (roughly "broken") or irrelevant drivers, you can easily remove them. Using this program looks like this:

download the program (here is the link);
install it and run;
an automatic scan will take place, after which just click on the "Update All" button.

DriverPack Solution Window

Scan the system with your antivirus and remove any detected viruses. And also for this 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 your system back to a point where everything worked well.

To do this, you need to do the following:

open the "Start" menu, then "All programs", "Accessories";
then go to the "System" section and click on the "System Restore" item;

The "System Restore" item in the "Start" menu

in the window that opens, click "Next";
then select the desired restore point, and here they are sorted 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 reinstall the drivers and roll back the system even in cases where in safe mode the keyboard does not work properly either. 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 failure

In this case, you will have to disassemble the keyboard and look step by step what could be out of order there. To do this, follow these steps (it is very important to adhere to the order in which all the steps will be listed below):

1. Turn off the laptop and remove the battery from the laptop.

2. Take a flat-blade screwdriver and gently slide out all the latches on the plate that holds the keyboard. If you do not see any latches on your laptop, you should take the instructions in hand and read what it says about the keyboard device and how it is removed. In any case, some kind of fastening mechanisms must be present.

4. If the ribbon cable is not damaged, it must still be removed. In this case, the loop should not be taken by the conductors in any case! Only handle the plastic parts that attach it to other parts of the laptop. For clarity, Figure 10 shows the parts that you can tackle and those that you cannot tackle. True, in keyboards, several different loops are usually used.

5. In the same place, under the keyboard plate, you can find a microcontroller. It is necessary dry and try to draw out the dust using a vacuum cleaner.

Explaining how to find this very microcontroller is quite difficult. To put it simply, this is exactly the device to which the loop is attached. Just in case, when removing the keyboard, go through all the controllers you see. You can't do anything on your own without special knowledge. Again, if you see obvious damage on the microcontroller, it is best to replace it.

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 off with the same flat screwdriver. Start with the problematic buttons. If you see damage underneath, replace the parts that secure the button 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 underneath. Usually she also has special mounts that can be removed quite easily. But under it is a plastic board with painted paths.

Examine it for any obvious damage - if any, there are two options: draw new tracks or buy a new board. Either way, vacuum the board over the board.

Use a tester to check the integrity of the tracks.

To draw the tracks, use the car rear window heating thread repair kit (that's what it's called).

If all else fails, your best bet is to have your computer repaired.
