Hi all,
I have a client's laptop in at the moment, and I've got a problem with the machine that I can't really explain. The laptop is a Compaq CQ57 which has definitely seen better days.
Part of the job involved giving the machine an internal clean out and performing a bit of a repair to a broken headphone jack, which necessitated removal of the keyboard (among other things). Something sticky appears to have found its way under the keyboard at some stage in the machine's history, and when I've lifted up the keyboard I've damaged the ribbon cable, and a number of keys didn't work.
That's my fault, so I organised a replacement keyboard, and everything seemed to be okay. I ran a full check of every key, and both the Alt and Alt Gr (it's a UK kbd) don't register, but all the other keys work fine.
I've put in another new keyboard, with exactly the same result. I've ruled out the OS - the keys don't work in any environment, right from power-on (including the bios). An external USB keyboard tests fine. I don't definitively know whether the alt keys worked when I first got the machine (the client doesn't recall any problems with the keyboard, but I've no way to know whether that's truthful or even whether he uses the alt keys much).
In my time with the machine, I have had the motherboard out of the machine, so I guess it's possible I've damaged the board in some way (although obviously all appropriate precautions were taken), but I find it hard to believe that only these two keys would exhibit problems. I've also updated the BIOS, but with no change to the problem.
Can anyone please think of anything I'm missing here? I'm a bit stumped on this one.
Thanks,
Michael
