#474724 - 02/24/08 04:18 PM Mini Wont power up [Re: MacLovin]
owaring Registered: 02/24/08 Posts: 3	For an unknown reason my mini has stopped booting up, I have tried 2 power supplies, and even metered them and all is good. I have tried both methods of resetting the PMU (internal and external) I have checked the internal 5a Fuse (its good!) Short of looking for another logic board or even mini, i wondered if any body had any other ideas? Many thanks

Then try disconnecting everything from the board except RAM and testing. Don't run it without the fan for too long or it'll fry. I have seen other parts including the fan cause startup failure and other odd symptoms. You might also check the fan for obstructions. I had one where a loose screw got into the fan and jammed it completely. It wouldn't start. Or maybe it was randomly shutting down. I forget.
