my laps some keys not working

if your lap keys not working, try to clean it in keyboard cleaning brush..some times dust will block the keys functioning ..
Try taking a look at the retainer clip under the key, or the rubber center piece, its one of more the pieces are broken then it will not make contact to the base of the keyboard and therefore it will not work, if there is cold season and you are not using the laptop regularly ..The problem could be on the keyboard itself. You will have to replace the keyboard to make all the keys to function. Once replaced they'll all be back to normal. it will cost 1200rs here .. Hope this helps and have a good one!
