    After reading several won't start post here, I still can't start the late 2004 Dual 2.0GHz G5 Powermac. When connecting to power indicator lite will flash once, then when I hit power button nothing. Tried holding button up to 20 seconds, still nothing. Replace battery hit button to reset, then apply power.
    (nothing) Pulled memory, no change. Reinstall memory in matched pairs, nothing. Reset PMU switch, nothing. Anybody have a new suggestion? Thanks

    Looks like dead PSU. Replace it. It could be pulled out from any AGP G5 that you have by the hand (easiest will be from single CPU version). Wattage don't matters.

    Thanks again 666 sheep (from an older post)
    I've also narrowed my display change sleep problem down to
    external speakers or ethernet (still working on that)
