Quick question: how do I figure out if the malfunction is really caused by the physical keyboard and not some soft/hardware issue that has nothing to do with the keys themselves?
Unless there’s liquid damage and it’s certain rows of keys not working at all it’s unlikely that you’d have that sort of partial failure of your keyboard. Even in that case it’s still usually the keyboard. If certain keys only work with excess pressure that’s pretty much 100% a hardware failure of the keyboard itself.
