My dad has a PMG4 MDD Dual 1.25Ghz.

Whenever he puts it to sleep, it won't wake up again without being restarted.

This problem persists with a fresh user, with no firewire or USB devices attached, with the standard configuration of RAM and with a clean install of 10.3 or 10.4.

As I type this I'm wondering could it possibly be the ATI card thats in a PCI slot. Its being used to drive a second monitor.

Or should he reset the PMU?

Or has anyone else any suggestions?

It will not hurt to start to reset the PMU, and check the battery too. While everything should work with it being dead, I have seen a dead battery cause erratic problems, short of not being able to retain the date.

Negative on the Applecare, its out of warranty.

I'll get him to reset the pmu and see if that helps.

I doubt its the battery, the clock is fine.
