I've got a bit of a problem. My laptop, nearing the end of its 5-year guarantee, has sporadic re-booting issues. It seems to re-boot when nudged, bumped, the screen is moved and sometimes just when you touch it around the mousepad.
The problem is, it doesn't do it all of the time so it would probably be hard to prove. When it's happening, it does it lots. But when it's not it can go for a week without doing it.
What would I do when ringing up about it? I can just see them sending it straight back and saying its "fixed". :-(
