No Display: constantly goes to sleep except with external monitor
My MacBook (2,1, C2D 2.0) will not show the display on boot and immediately goes to sleep once the operating system is loaded. If I press the power button to wake it, I see the desktop perfectly for about one to three seconds and then back to sleep. If I have an external monitor attached the the mini-DVI port none of these problems occur- it works perfectly. I have another broken MacBook and I've tried connecting it's display and inverter with no change. I also tried swapping out the sleep sensor with no difference. Anyone have any more ideas before I accept that i now have a pancaked Mac Mini?
Is this a good question?
