I have a fairly recent laptop. It works really well, except that the screws in it keep dropping out. This must be because I have taken it apart to mend or upgrade it that many times, that the teeth have worn down.
It's not the part of the screw which fits into the screwdriver, it's the tooth spiralled along the shaft of the screw which is worn, or the corresponding groove in the hole in the laptop. What can I do, that the laptop screws will stay screwed in and not drop out like this?
