Maybe it was because the battery ran out. In my defense, it should've been put somewhere visible. In any case, suddenly keys won't work. I can't use the left shift, D, Z, V, N, L and who knows what else.
I've done a virus scan and a malware scan and both turned out fine.
The only other options I can think of right now are looking for a way to boot in safe mode, finding where the screws are in this thing, or wait for tomorrow to get some compressed air, even though the odds of all those keys getting jammed up by magic flying crumbs seems extremely thin.
On a side note, a few weeks before, it would suddenly get stuck on random when I type. Something would turn into sssssssssommeeeeeethiiiiiiiiiiiiiiiiiiiing. It's even worse when you try to correcr it, you'd sometimes end up deleting everything before that word.
Edit: Did a run on keyboardtester.com
The faulty keys make a symmetrical layout with the keyboard. "D K Z V N ." and the up and right arrow key.
That can't be a coincidence. Aliens?
