So…I currently use a surface pro 7+ for everyday and all of a sudden my keyboard stopped working (For context here’s a few things that are normal): Surface turns onSurface reaches login screenSurface logs in and is on home screenSurface is in UEFI biosSurface is in Advanced startup options. In none of these scenarios does the keyboard work. No lights are on. No signs of life. However after a reset of windows it does work but then small things do trigger it to stop working again. I have tried literally everything from cleaning the contacts to even (repeatedly) turn on and off the type cover port in the UEFI bios with absolutely 0 luck at all. Pls help as this is a machine used on an everyday basis. Thanks.
Plugin the external keyboard to check whether the fault is in the keyboard or something else. As you said after windows reset it works, which means there might be some software glitch. Try to update or restore the updated driver for the keyboard. Sometimes keyboard gets turned off from bios too. You should also check from there.
