A laptop is a real assistant in work and a convenient replacement for a computer, you need to work with it carefully and carefully, otherwise such equipment will not be able to serve the longest period. If you find that the keyboard on the laptop refused to work, do not rush to the service center for help, perhaps you can solve the problem yourself.
A broken keyboard on a laptop is a much more unpleasant problem than a similar incident on a regular computer, because in the first case we are talking about an integral part of a single unit, it cannot be simply disconnected by pulling out the connector and replaced with another. The good news is that a breakdown of this kind is a rather rare event, but if you are faced with it and want to know why this happened, you should familiarize yourself with the most likely causes of the malfunction.
Program crash
The operating system may have crashed and stopped responding to button presses. For example, drivers have failed. To check this version, restart the laptop, enter the BIOS while holding the Del key, if it does not work, try F1, F2. If the keyboard responds in the BIOS, boot the computer in Safe Mode so you can see if the keyboard works under these conditions or not.
Poor loop contact
If you work with the laptop for a long time, the problem may be associated with oxidation or the pressed contacts of the keyboard cable. You can only find out that the reason is really this if you disassemble the laptop. Examine the cable itself by disconnecting it. If you notice any obvious damage, it means that it is causing the keyboard breakdown. The problem is solved by replacing the loop. If everything is normal with him, the contacts should be wiped with alcohol, then put the cable back in place and test.
Broken microcontroller or water procedures
The keyboard may fail due to a burnt microcontroller or liquid flooding. In this case, only a specialist of the service center will come to your aid, you can determine the hardware parts that are out of order yourself, but it is very difficult to replace them. If liquid spilled on the laptop gets on the board, it will oxidize its contacts, in which case the keyboard will completely stop functioning.
After spilling liquid on the keyboard, quickly turn off the laptop, remove the battery and dry with a hair dryer on the minimum setting, preferably with cold air. This manipulation will prevent or slow down the oxidation process.
Handle your favorite technology with care, do not drink it with spilled coffee, do not drop or drum on the keyboard with your fingers as if you were in front of a mechanical typewriter, in gratitude the laptop will serve you much longer.
