hi guys. right heres the story. I was installing magic keys into the slimline earlier and trying to sort out Tool C. i could get it working but had to fiddle about to get it to stay. then all of a sudden it wouldn't power up.red light comes out, when pressed it stays green for a second and then goes back to red..... I opened it up and looked ok. only thing i could see was near where tool C needs to go, just under the mother board cover was a small component and on the silver of it there was a light mark which is obviously made being touched by the tool c when trying to get it right. what's the story here? I'm really pissed about this cos i was just planning on opening it up and taping the switch but thought I'd have 'one more go'. seems this one more go has cost me lots! I think the important thing is that it does try to power up. nothing wrong with the switch or anything.
