I have a problem on my XP laptop that some of the keys on the keyboard are not working. E.g 13568&0 work but not 247&9, same sort of thing with the letters, O works but not P.
What I have tried so far:
Restore to an earlier point. (this did work the first time but when the problem returned shortly afterwards I tried the doing same with no success)
Checked the keyboard connection to the MB.
Uninstalled the keyboard driver. (Windows re-installs this automatically when you restart the PC)
Tried an exorcism to drive the demons out (no success)

Can anyone help please!

What brand and model?

How old is it? Is it still under warranty?

No specific brand (custom build for video editing)
4 years old, so no warranty

a bit more detail, by not working do you mean that the key does not type or that another key is in its place

any incident that you might remember that has caused this problem, have you banged the laptop at some point, one idea is that there is a tapelike cord under the keyboard which connects to the motherboard and this could be playing up, but that would be a repair shop workload not yours

if, and I don't thnk so, it is software then perhaps a repair with cd might work

btw exorcism is done by our clairvoyancy department(security), not in the goblin's lair(hardware)

Another thing to try is attaching an external keyboard to it, to see if you get the same behavior. That will tell you if it's particular to the laptop keyboard (wiring or key membranes), or if it's the controller.

Another possible cause of malfunctioning keys is liquid spill. Is there any indication on or around the keys that are acting up that liquid might have been spilled there?
