The keyboard is an integral part of any computer, including a laptop. The correct operation of this device ensures the operability of the entire PC, because when the keys are malfunctioning, many options on computers become unavailable. Although, you can turn on the on-screen keyboard and control the PC with the mouse, but it is not very convenient, and complicates the work with the computer.

If this device on a regular computer does not meet the necessary requirements, then you can easily replace it with another one, since the connection and configuration process is very simple. It is enough to connect the new device to the USB connector, and the system itself will install the necessary drivers, and the keyboard will immediately be ready for use. With a laptop, everything is not so simple, because the keys there are built into the case, and the replacement process is akin to a medium-complexity repair.
There are malfunctions of various kinds, and with some of them it is not necessary to disassemble the design of the laptop. In order to choose a suitable repair, it is necessary to diagnose the problem itself. There are several reasons why the keyboard does not work.
- Software crash. If nothing happens when you press the keys, or the reaction does not correspond to the press of a button, there may be a problem with the settings. In order to check or fix this malfunction you need to go in BIOS. If you can control the keyboard in the BIOS system, then the problem is a software failure of the operating system.
ATTENTION. To enter BIOS, you need to press the DEL key during boot, when the line “Press DEL to enter SETUP” appears. An alternative way would be to press F1–3 or F10–12. Also, on some models in the BIOS, the Esc button comes out.
- Problems with the loop. Typically, such a malfunction is observed during prolonged use or severe physical damage. In order to check the integrity of the cable, you have to disassemble the laptop.
ATTENTION. After the device is disassembled, it is not subject to warranty repair. Warranty service may come in handy if the violation of the integrity of the loop is a factory defect.
- Malfunctioning drivers or software. There is a separate driver for each connected device. If for some reason it cannot function, normal operation of the device becomes more difficult. Usually, software problems occur when an unsuccessful attempt to update, or when installing them manually. To check the operability of the drivers, just go to the BIOS. If the arrows work fine in this system, then the problem is precisely in the software. Also, an alternative way to check is to boot Windows in safe mode. If the keyboard works fine in this mode, then the problem is with the software or drivers. To fix this problem, it is enough to manually download the latest software from the official website of the device manufacturer.
- Faulty contacts. Typically, this problem occurs due to external influences. Contact disruption can be caused by spilled liquids or physical damage. Typically, a malfunction of the contacting surfaces results in poor performance of some keys. To check the correct operation of the buttons, you can use special services to check the keyboard.
Programs for checking a laptop keyboard
In order to check the buttons of the laptop for performance, there are many different programs. The most popular of them: KeyboardTest.
This utility allows you to check the performance of not only the keys, but also the indicators on the keyboard. The program has a list of the most popular devices, as well as a constructor, so that the user can assemble his device close to the existing model. KeyboardTest also allows you to test a computer mouse, testing it for the speed of the sensor, the accuracy of determining the coordinates and the response speed of the buttons.
Online services for checking keyboard operation
Among online services, Key-Test should be highlighted. This service allows you to check all the main buttons. For correct operation, it is better to use the English layout.
The check is a virtual keyboard displayed on the screen where the pressed key is highlighted. If it works properly, it is marked in white, if there is any malfunction in red.
