I had originally posted this in the teardown thread, but given it doesn't get nearly as much traffic as this thread does, I'll try my luck here. I have one of these that had been left on overnight and was dead the next morning. It won't power up at all. I've tested the power supply and it's good. I even tested the power button and auto off switch with my multimeter and the continuity tested fine with pushing/switching each with the points i tested. I don't know enough about the power on circuit to really do anything there. I read over at headfi of some early ones having issues with the power on circuit. Is there a way to bypass this circuit and use a traditional power on switch to at least rule out anything thing being wrong with the rest of the unit?
