I have a HP dv6t that's about 2 years old now, and it kept randomly shutting off. Well, I thought it was some massive fan and/or battery issue, but it seems like it's some other bizarre problem.... I just figured out that if I tilt the screen back too far (somewhere past 90 degrees), it'll just power off, and get stuck in an on-off cycle until I reduce the angle of the tilt. Anyone have any idea at all what could be causing this? (willing to open it up myself, but I've got a stripped screw so I'd have to deal with that too)
