|Hi M, |
have you done anything (spilt liquid?) that may have caused this. You have not advised the model number which may have helped.
Below are suggestions in the order I would attempt:-
a) using a can of compressed air (available here in the UK in cheapo shops such as Poundstore) try blowing out any muck that may be under the keys concerned.
b) remove and reinstall keyboard. Disturbing cures many faults!
c) obtain and fit new oem keyboard which will be much cheaper than manufacturers one.
Please advise back on progress.
Good Luck - Keep us posted.
