Laptop keyboard problem

Sep 24, 2018
Hi all, I have quite a strange situation going on. One of the laptops is experiencing quite an interesting problem: the Backspace, "\", and Enter keys sometimes work, sometimes don't. I tried to remove the keys and touch them without the actual key caps, but it wouldn't work either.

Once you put it in the place and lock it, it stops working. It may or may not work, but most of the time it doesn't work, and when it works, it works only for a short period of time.

Any hint on where to look for the problem resolution will help.
