Have you repaired it yourself at some stage?
It's quite common fuses to go in self-repaired consoles......don't ask me why.
Possibly static damage of some sort weakens the fuse itself? I really dunno.
Yeah, I'm assuming that's what it's related to. I never repaired anything inside, but I swapped out the plastic when my hinge broke sometime last year, which of course requires the top screen, speakers, and wireless card to be un and re-attached.
