My hp85 has a problem. It turns on, and it passes its self test. However, after ~1-2min it turns off and then back on again and hangs. If I tap on the corner (near the power switch) it will come back on. It of course sounds like some kind of intermitancy. I think I've traced the problem to a bad power switch. When I test the continuity across the switch in its "on" position, my meter reads closed for a while and then reads open.
Any thoughts? It seems like a high quality switch but I suppose it could certainly be to blame.
