Why the keyboard doesn't work: main reasons, symptoms, solutions.

Signs of a keyboard malfunction

To fix the problem, you need to establish its cause, which means figure out why the keyboard on the laptop does not work: due to mechanical impact or spilled liquid, after visiting dubious sites or installing new software. Or maybe malfunctions began to appear suddenly, without any reason .

Also should be checked don't work separate buttons on the keyboard or has it completely failed, and if so, has it stopped working in the operating system or in the BIOS too.

Symptoms of a broken keyboard:

Spilled liquid

The keyboard has been exposed to water, tea, coffee, soup, alcohol

If you spill any liquid on the keyboard, turn off immediately laptop: holding down 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 leak under the keyboard, into the computer. This may cause a malfunction 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: just press something thin onto the latches located on top or sides of it Their location varies depending on the manufacturer and laptop model..

Be careful: the keyboard is connected to the computer by a thin cable, try not to damage it with an awkward movement. Now you need to wipe the keyboard with an alcohol wipe and leave it to dry. You can speed up this process with a hairdryer, but only with cold air.

When the keyboard and laptop are completely dry, put it back and try turning it on. There is a possibility that now everything will be the same as before, but if any malfunctions appear, there is only one way out: replacing it with a new one. If the laptop stops turning on at all or is unstable, feel free to take it to the workshop. With such breakdowns to a simple user can't handle it on your own.

Some buttons on the keyboard do not work

The keys do not respond to pressing or print the wrong characters

If without visible reasons If any buttons on the keyboard do not work, while others continue to work, then you should check, firstly, whether your Num Lock. If this is the problem, then the numbers are on the right
will not work on the keyboard, the computer will see arrows instead . Find the “Num Lock” button to the left of them (in the upper right part of the keyboard) and press it. On some laptop models, you need to press one of the hot keys (F3, F11, etc.) together with the function (fn) key.

If other buttons stopped working, check to see if there is any dust underneath them that is preventing them from being pressed. IN in this case You should either thoroughly blow out the keyboard with a special can, which you can buy in a store, or remove the keys, carefully pry them off with something thin (for example, a screwdriver) and wipe the keyboard manually.

The whole keyboard doesn't work

Not a single key on the keyboard responds to presses.

If for no apparent reason the keyboard on your laptop does not work at all, try rebooting it and entering the BIOS. If before loading Windows keyboard If it works, it means the problem is in the system, and you won’t have to spend money on a replacement.

Most likely, a virus has appeared on your computer, which has removed or the corresponding driver has become corrupted, which is the reason why the keyboard does not work. Swipe full check using your antivirus, and after finishing 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 installer's instructions. In the second - click right click on the “Computer” shortcut, select “Properties”, in the window that opens on the left top corner Click on “Device Manager”. In the manager, find the “Keyboard” line, open it and see the corresponding device. Double-click on it with the left mouse button, or right-click and select the “Properties” option. In a new window, open the “Driver” tab and click “Update”.

If this does not help (no virus was detected or the system did not find more suitable driver, and the keyboard still does not work), you should try restoring or reinstalling Windows.

Even if Keyboard doesn't work in BIOS on a laptop, the easiest way is to take it to a workshop, especially if you have never repaired computers yourself and have no idea how to do it. Not only because by acting at random, you can damage your laptop even more, but also because not every store will be able to find exactly the keyboard that your laptop needs. In our workshop we will select required device ourselves and install it correctly.

However, if along with the keyboard you have touchpad doesn't work and USB inputs, then be prepared for the worst: this is a clear sign of a faulty motherboard. Its repair or replacement requires much more time and money, and this certainly cannot be done without the help of professionals.
