MDD G4 PMU Reset
I just had the power go out in my work, wghich has 150 Macs. All of them rebooted after losing power, except a majority of my MDD (Mirror Drive Door) G4s. They wouldn't reboot after the power outage. I had to press their PMU reset buttons manually on the motherboard. All of them booted fine after I did a PMU reset. Any ideas why?
