Resurrected my laptop!! but some keyboard-hangover bits

Laura Arjona Reina at

Last Christmas my laptop harddisk began to fail, and it seems I broke the keyboard when replacing the disk. After trying many times to solve the problem, I took the laptop to a repair shop, and now I took back repaired #oleole!!

Well, almost repaired. They cleaned well everything and repaired some keys connectors (they said), and everything seemed to work again, so they didn't put a new keyboard (would be more expensive). At home, TIL xev and I realized that some (very few) key combinations still don't work. Among the ones that I use frequently: Ctrl+Z, Ctrl+X, Ctrl+C #grr! (neither left or right ctrl with those keys give output in xev, while pressing the ctrl keys alone or the letters, there's output). Another example: Ctrl+Alt+F2 switches to tty2, Ctrl+Alt+F3 nothing happens, Ctrl+Alt+F4 switches to tty4.

I don't use the Super (former Windows) key, so I remapped it to be the left Ctrl (TIL xmodmap, later I'll see how to do something similar with the non-graphical mode.

Being the fact that what fails is "some key combinations", but not the keys alone, I'm not sure if this is a problem beyond the keyboard (motherboard? connector?) and so, giving more money to get the keyboard changed would only postpone the problem.

Tomorrow I'll try to talk with the technician that repaired my keyboard, and probably I'll leave it there some more days to see if they can do anything. But tonight I'll enjoy my computer again! With a fresh Debian stable minimalist install, XFCE, iceweasel and pumpa of course :)

aether, RuiSeabra likes this.

Great luck there!

i had a similar problem with my laptop a couple of times. re-flashing the 3rd-party modified bios i was using did the trick each time. (the mod is to diable the wifi card whitelist in that proprietary p.o.s.)

my theory is that there was either a rootkit installed by the modder, the bios creators, or by an os-level rootkit. as the buggy bios rootkit runs for a while, it may hit a corruption bug and partly over-write the bios while saving key strokes in the free space there. ;-)

granted, it could just be that proprietary software is already a total pile of crap. good luck with your computer! :-)
