Is this something that's fixable on a laptop? What could be causing it?
(It's a Sony VAIO VGN FS Six40...aha...had to type six...sorta amusing... Anyways...I got it two years ago.
If you think you know what you are doing, try taking off the top of the keys and see if there is something in the way of the contact.

Also, try pressing the key without the top. If it still doesn't work, definitely have some licensed shop see it.
you will be able to use those keys right now but i'd think getting it fixed would be better option.
