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?
