Why the wireless keyboard does not work on the computer. What could be keyboard faults

Hello everyone.

Today I am writing an instruction for those who do not work the keyboard on the laptop. I will describe the reasons why it could happen how to try to solve this problem so that the keyboard earned, show a temporary solution, as you can do without a keyboard and give some tips.

Video: Keyboard does not work on a laptop

Test keyboard via bios

First of all, look at how the keyboard behaves when the laptop is turned on. Try to go to BIOS. When you start the laptop immediately start pressing the Delete or F2 key (depends on the motherboard). If the input into the BIOS is executed, then the keyboard is proper. You can like the BIOS menu and accurately make sure that everything is in order with the keyboard.

Keyboard fault

If the BIOS keyboard does not work either, that is, the likelihood that it completely failed, but not a fact. Think, and whether such a keyboard was filled with tea or beer a couple of days? And if the keyboard has been working in the BIOS, then it's most likely a software malfunction and you need to solve through Windows.

Reinstalling drivers

Click on the Computer section and open the properties. Next go B. Device Manager.

Find the keyboard section and delete everything under clean.

Driver will be removed! Now restart the laptop and check if the keyboard has earned.

System Restore

It happens that some programs or we ourselves ourselves in the system, installed something wrong, or vice versa deleted important files and Windows now works not stable. Do not work the keyboard on the laptop can also because of this. I propose to make the system restore!

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

Perform Running system recovery.

We choose the recovery point of about that date when the keyboard worked and click further.

A rollback will be completed and the laptop will reboot!

In any case, while the text can be typing using the virtual keyboard or as it is also called.

Open the search string and enter the request (or start - Specialist. capabilities -). Run the program found.

Now we can dial with her text. For example, I opened a notebook, put the mouse cursor and started pressing the screen of the on-screen keyboard. Set of text went.

You can also enroll with the search string of Yandex.

But I have to say that not some sites already have its own on-screen keyboard. On the main page Yandex is on the right of the form.

Click there and starts such a beautiful keyboard.

It is natural to work only on Yandex, to enter a query in the search string.

By the way, Google also has its own screen, so if you have a keyboard on your laptop, then at least to find something on the Internet and drive the text in a notebook, you will definitely.

Connecting usb keyboard

If it was not possible to restore the keyboard built into the laptop, then the external can be connected. Yes Yes exactly! Keyboards that are designed for computers will easily fit for laptops. The main thing to choose USB keyboardBecause it is unlikely to have a PS / 2 port on some laptop today. And here USB connector There is on any laptop.

That's all. I hope any of the options you managed to resolve the question with the keyboard. See you in new lessons!

In the process of working with a computer, many users have difficulty blocking when half the keyboard on the laptop does not work. Because the use of the keyboard allows you not to simply speed up the operations for the laptop, but also to facilitate the life of its owner, it is necessary to eliminate this problem as soon as possible.

Arising problems with the work of the keyboard

Among the main reasons why the keyboard can be opened, both technical problems and the influence of the human factor can be called. And if everything is clear with the first, and a private user can hardly affect the equipment of the equipment, then a frequent cause of the breakage is toasting keys.

If you pour the keyboard with a liquid, the process of corrosion arises, which displays contacts. To avoid breakage, you need to completely disable the battery and turn the laptop to the glass liquid, and then wipe the surface of the keys.

After a day after drying, the keyboard will have to earn, but if this did not happen, the equipment should be attributed to the service center.

Ways to force the keyboard to work

The keyboard may be blocked while pressing multiple keys. To unlock it, it is necessary to dial the Fn + Numlock commands or Fn + F7. This allows you to solve the problem of randomly blocking a fully sound keyboard.

The laptop keyboard may be inoperable if incompatibility with current drivers occurred. To eliminate the problem, it is recommended to return the system to previous state Through the control panel - all the control panel items are restored - start the system recovery. When the system returns to the recovery control point, the driver also goes to the previous compatible state.

You can also completely reinstall the operating system, or delete the drivers and download the original from the manufacturer's website.

How to avoid keyboard breakdown

If the keyboard continues to remain blocked, the equipment is worth passing into repair. A temporary solution can be to use the keyboard on the monitor screen.

In order for the laptop keyboard in good condition, it is necessary to regularly maintain its cleanliness, prevent the battery overheating and timely install the system updates.

Sometimes users encounter such a problem that they do not work part of the keyboard on the laptop.

In principle, it happens that the entire keyboard does not work immediately, but then, most likely, it just needs to be replaced. But if only part of the buttons stops functioning, everything is more complicated.

We will consider everything that can be done in this case independently, without the involvement of specialists.

Simple ways to solve the problem

Not always to restore performance, you need to do something complicated. Often the problem is solved quite simple.

Therefore, from the beginning, do this:

1. Try click on the Fn keys and Num Lock. 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, such a simple way allows you to start a full-fledged keyboard operation.

3. Take a brush and pass it on all buttons. It is possible that some dust accumulated under one of the buttons. If possible, take the vacuum cleaner. On the Internet you can find special vacuum cleaners for keyboard small size.

4. Restart the computer. In some cases, the system may have some minor bug that does not allow specific buttons.

In most cases, the problem will be insignificant, and it can be corrected using one of these actions. If nothing happens, go to the next step.

Fix the program failure

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

It is best to do this in the standard way:

open the Start menu (Windows), then "Control Panel", Find there "Device Manager";

Device Manager in Control Panel

open the keyboard item;
usually there is only one keyboard, click on it with the right mouse button and select item "Update drivers ..." (if there are several keyboards, which is very unlikely, do the same with everyone);
choose item « Automatic search…» ;
wait until the drivers are found on the Internet, their installation will occur in automatic mode.

Drivers standard update way of windows

And you can also download and install the program DriverPack Solution. It allows you to scan the entire computer for the presence of the latest drivers available.

If the keyboard has incorrect (roughly speaking "broken") or irrelevant drivers, you can easily bring them. The use of this program is as follows:

download the program (here is the link);
install it and run;
there will be automatic scanning, after which simply click on the "Update All" button.

Window DriverPack Solution

Read about other good similar utilities.

If the update and scanning of the drivers does not help, try to roll back the system until it worked well.

To do this, you need to do this:

open the "Start" menu, then "All Programs", "Standard";
after that, go to the "Service" section and click on the item "System Restore";

Item "Restore System" in the "Start" menu

in the window that opens, click "Next";
further select the desired recovery point, and they are sorted here by date and time (you need to choose the one that most accurately matches the time when everything was fine);

Choosing a recovery point for system rollback

click "Next" and then "Finish".

In principle, and roll back the system and in cases where safe mode The keyboard also works incorrectly.

But in this case, the probability that it will help, very small.

Most likely, the problem is already mechanical, and not software and solve it needs to be physically interfered with the computer.

Fix physical failure

In this case, it will have to look like a phasepan, what could fail there.

To do this, follow these steps (it is very important to adhere to just such a order in which all actions will be further listed):

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

2. Take a flat screwdriver and carefully push all the latches of the plate on which the keyboard holds. If you do not see any laptops on your laptop, you should take the instructions and read that it is written about the keyboard device and how it is extracted. In any case, some fastening mechanisms should be present.

The process of opening the keyboard plate latches

The keyboard plate is attached to the laptop itself using a loop. You will immediately see it.

3. So, if it is clear damage, the loop you need to just take out and replace the new one. To do this, take the old train, go to the nearest electronics store and buy the same.

4. If the loop is not damaged, it still needs to be removed. The cable at the same time to take the guides in no case! You can take only those plastic parts with which it is attached to. For clarity, in Figure 10 shows those parts for which you can also be taken and those for which it is impossible to take. True, there are usually several other loops in the keyboards.

5. In the same place, under the keyboard plate you can find a microcontroller. It is necessary dry and try to pull dust With the help of a vacuum cleaner.

Explain how to find this most microcontroller is quite difficult. If you just say, this is exactly the device to which the loop is mounted. Just in case, when removing the keyboard, pass through all the controllers that you will see. Alone without any special knowledge nothing will do anything else. Again, if you will see explicit damage on the microcontroller, it is better to replace it.

6. If everything is fine with the loop, you have to disconnect the keys and clean them. Usually, the button can be removed in the standard way - to pose the same flat screwdriver. Start with problem buttons. If you see damage under them, replace the items that the button is attached to the laptop.

7. Try to use the keyboard again.

If the problem has not disappeared, remove all the buttons and remove the aluminum plate that is under them. Usually, she also has special attachments that are removed quite easily.

But under it is hidden plastic board with drawn tracks.

Inspect it for obvious damage - if any, there are two options: draw new tracks or buy a new board. In any case, walk along the platform with a vacuum cleaner.

To check the integrity of the tracks, use the tester.

Part of the keyboard on a laptop does not work: what to do and how to fix - detailed guide

Hello.

The keyboard laptop stops working as often as the keyboard of the usual stationary computer. True, if the keyboard of the usual PC is easily and quickly, you can disconnect and connect a new one (at least for verification), then a laptop is somewhat more complicated ...

In general, the reasons for which the keyboard does not work on a laptop is quite a lot. In this small article I want to disassemble the most common.

1. Installation of malfunction ...

If the keyboard stopped working suddenly, without any serious causes (for example, a drop in the device) - then the first thing I recommend to do is check, "Is it completely not working" or only in Windows?

The fact is that some viruses and especially drivers (for example, on Bluetooth) in case of failure can lead to a touchpad and keyboard disconnection. Most fast way It is checked - go to the BIOS.

How to enter the BIOS (input keys) -

If you entered the BIOS and the keys there work - Most likely the cause of a fault in Windows. In this case, you can try to boot in safe mode (or with the help) and check if the keyboard works. If it works - the reason in Windows 99.99%! In this case, one of the simplest solutions to the problem is reinstalling Windows (or search for failure driver, you can learn in device Manager).

Device Manager: There are no drivers.

If you are not included in the BIOS - the keyboard does not work completely and the matter is not in the drivers or windows crashes. In this case I recommend trying to connect to USB port. Mouse and keyboard and look at their performance. If they also do not work - the problem may be in the burnt chip on the mat. Place (without a service center no longer do).

2. Problem with drivers.

As already said above - a very popular reason for the keyboard failure. It occurs in most cases due to drivers on USB and Bluetooth. To solve it: you can roll back the system (restore), if there is control Points restoration; remove failed drivers; Reinstall Windows.

1. Restoration of the system

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

2. Delete / install drivers

I have some good articles on this blog. I will give here links to them. In general, you need to: Delete fully crashed driver, and then download drivers from the official website of the device manufacturer.

3. Reinstalling Windows

Reinstalling Windows 7 instead of Windows 8:

3. Is the battery right ...

The fact is that some models of laptops due to a specific design may not work at all correctly with the battery. Those. If it is connected to a laptop and discharged (or just does not work) - then the keyboard can stop working. It is easy to check if you turn off the battery from the laptop and connect it to the network.

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

4. Is the train in order ...

If the touchpad on the laptop works, the connected keyboard and the mouse to USB also work - it is possible in the loop: it could simply move away (or because of non-dense contact, or when moving the device). Also, the cable from the keyboard could be incorrectly attached if you recently removed the keyboard (for example, when cleaning a laptop, and indeed when disassembling the device).

It is also not excluded and the fracture (inflection) of the loop (this may be due to the unsuccessful design of the laptop.

Laptop keyboard: Loop for connecting to the device.

Important! To remove * keyboard from a laptop, pay attention to its outline: from above and below (sometimes with the left and right) sides will be small latches. It is convenient to pry an ordinary screwdriver, and then carefully remove the keyboard. It is necessary to act without hurrying, the train in some models is quite thin and damage it is very simple. If I have never disassembled your laptop before, it is probably worth contacting the service center.

* By the way, in some models of laptops - it is not easy to remove the keyboard, you need to pre-unscrew the additional mount.

5. If several keys do not work

When dust (or small particles, crumbs) under the keys - they can stop hardware. Pretty frequent cause of the inoperability of individual keys on the keyboard. Fighting this attack is simple: produce cleaning from dust and not to take the device into the kitchen (as many people like to do ...).

6. Spilled keyboard

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

Action at the entity:

Disable from the power completely and as quickly as possible (remove the battery from the device housing, turn off the power supply);
Turn over the device: so that the liquid all flows down;
Do not include the device to complete drying (usually 1-2 days).
It is advisable to show the device in service center. The fact is that even if the device will work after switching on, the corrosion process is not excluded, which could begin. And in a short time, the laptop may fail (especially if there were "aggressive" fluid sheds: coffee or tea with sugar, coca-cola, pemps, juices, etc.).

6. Temporary measures

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

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

2) Turning on the on-screen keyboard (especially help you, if you do not work 1-2 keys that need to be pressed from time to time).

How to turn it on screen keyboard? Go to " Control Panel \\ Special Features \\ Special Features", Then turn it on.

Good luck!

Sometimes users encounter such a problem that they do not work part of the keyboard on the laptop. In principle, it happens that the entire keyboard does not work immediately, but then, most likely, it just needs to be replaced. But if only part of the buttons stops functioning, everything is more complicated.

We will consider everything that can be done in this case independently, without the involvement of specialists.

4. Restart the computer. In some cases, the system may have some minor bug that does not allow specific buttons.

In most cases, the problem will be insignificant, and it can be corrected using one of these actions. If nothing happens, go to the next step.

Fix the program failure

It is possible that the problem is in the wrong operation of some programs or services. To check this option and correct the problem, you must do the following:

1. Boot from under the secure mode without drivers. To do this, restart the computer and immediately start pressing the F8 button. Among the download options will select "Safe Mode".

Note: Depending on the system configuration, the button to select the download mode may differ. Therefore, try using all the buttons from F1 to F12, if pressing F8 does not help. As a result, such a window should appear as shown in Figure 2.

System loading mode selection options

2. Try to create some kind of document and use all the keyboard buttons. You need to check not only those buttons that previously refused to work, but all the others! If it really is in software failureThe set of broken keys can change each time a new start.

So, if all the buttons work well, then the problem is really in operating system. The most likely solution to the problem lies in updating drivers. It is best to do this in the standard way:

open the Start menu (Windows), then "Control Panel", find there "Device Manager";

Device Manager in Control Panel

open the keyboard item;
usually there is only one keyboard, click on it with the right mouse button and select the "Update Drivers ..." item (if there are several keyboards, which is very unlikely, do the same with everyone);

Scan the system with your antivirus and delete all detected viruses. And also for this you can use special utilitiessuch as Kaspersky Virus Removal Tool or MalwareBytes Anti-Malware Free.

If the update and scanning of the drivers does not help, try to roll back the system until it worked well.

To do this, you need to do this:

open the "Start" menu, then "All Programs", "Standard";
after that, go to the "Service" section and click on the "Restoration System" item;

Item "Restore System" in the "Start" menu

in the window that opens, click "Next";
further select the desired recovery point, and they are sorted here by date and time (you need to choose the one that most accurately matches the time when everything was fine);

Choosing a recovery point for system rollback

click "Next" and then "Finish".

In principle, reinstall the drivers and roll back the system can also be in cases where the keyboard is also incorrect in safe mode. But in this case, the probability that it will help, very small. Most likely, the problem is already mechanical, and not software and solve it needs to be physically interfered with the computer.
