What r the causes for non functioning of some keys of keyboard of computer?
Underneath the keys there a small clips which are slightly springy. Sometimes these get dislodged slightly or blocked with dirt and prevent the connection when pressed. To test this you could take out one of the keys and ensure it is correct underneath. If you are unsure of how it should be, first remove a key that is working. Please do this carefully and one at a time. to remove a key simply use a small object to slide underneath it an ‘Flip it out’. when finished locate it back in the correct position and press down gently until it clicks into place.
