I have become owner of used laptop HP 2510p. Raw of keys was not working at all: 9 O L . I've ordered and replaced with new one, but problem didnt change a bit these keys still not working. Can anyone suggest where to look? Thank you.
Sounds like the keyboard encoder circuit could be defective, in which case, you may need a new motherboard. Check to see if the keyboard connects to a smaller board that is on the motherboard, or does it connect directly to the motherboard?
So.. noone? There is no spare motherboard to test if this one is broken. It is not windows issue, cuz the same situation can be seen in DOS mode. Bios update didnt help either.
Yep, extrenal and virtual keyboards working just fine. I've just checked circuits and wires - everything looks fine here too.. Im starting to believe that it could be motherborad chip, but maybe anyone would give me another idea to check.
