Keyboard stopped working on my Acer Aspire 7 A715-75G laptop. The keyboard does not work even in BIOS, while the laptop power button works.
When I turn on the laptop on the keyboard, the backlight lights up for about 3 seconds, then it goes out and when I press any key nothing happens. If you go into BIOS on a laptop, then the keyboard does not work there either.
The drivers are installed and in the Device Manager everything is written as "installed and does not require updating." All other functions of the laptop work. For example, if you connect a keyboard via USB.
The main question is the matter in the keyboard, or maybe something else? And if someone knows, can you tell me what other methods for checking the keyboard are?
