A couple days ago, my notebook keyboard suddenly stopped responding to ANY input at all. Tried pressing every key and combination I could see, but no reaction. The mouse was working and the PC showed no other strange behaviour. I pressed the power button to put it to sleep, and then woke it up. The keyboard worked fine. This problem kept repeating and became increasingly frequent over the span of a few days. Now it's reached the stage where only a full restart will fix the problem, and that doesn't work every time.
I took the whole system apart and checked the wires, made sure everything was connected properly, and gave everything a clean and refitting just to make sure - no solution there. I also uninstalled the two keyboard drivers that were installed, and reinstalled them - no solution there, either. Nothing I've done seems to have affected the keyboard at all.
Sometimes, the Caps Lock light flashes slowly after starting up - I can only assume it's trying to tell me something, but I can't figure it out. I'm running Windows 10 on a 64bit system. Can anyone think of any possible solutions? Thanks in advance!
