Computer keyboard failure "this is a problem that we often encounter. This phenomenon is generally due to dirt on the circuit board or conductive plastic, which makes it impossible to connect the two normally. Other factors are also possible, such as damage to the keyboard plug, faulty wiring, damage to the motherboard, malfunctioning of the CPU, etc., but they are not the main causes. Therefore, we only need to carry out descaling work.
Causes and Solutions of Notebook Keyboard failure

In the case of determining that there is no fault in the laptop hardware:
There are two operations ：
3. One： turn off the computer, unplug the power supply and remove the battery, and then install it in a few minutes. Turn it on again to see if the fault is eliminated. That's how I did it last time.
4. Second： if the above 3 methods do not work, I recommend you simply reinstall, you can use U disk to start to back up the data you want, after starting with U disk, your keyboard will be good.
