My laptop keyboard (Asus ROG G750JH) is not working properly. When I press a key, most of them don't do anything, some of them send the wrong characters, some a few lines, eg: 65s073, but there are some that open a webpage (for some reason several buttons work as CapsLock). Updating drivers does not help, I don't know if it is a windows error. I wanted to try booting a linux from a pendrive, but I can not open the bios because the external keypad will receive power as windows starts.
