Green keys are recognized when hit, mainly focused on the alphabet section. What would be the best way to clean a laptop keyboard without damaging the keys in any way?
I think it depends how the keys are affixed. But the old standby canned air. Did you try a Live Distro to make sure it's not a software problem?
I just had a problem with some keys not being recognized in games, and the culprit turned out to be Ghostpress anti-keylogger from schiffer.tech... do you have that or similar software?
I recently reinsalled Windows, it was happening before that and has been for a while, use a USB keyboard to type now. Don't have it installed this time.
