Hi Mike, Wonder if it is your motherboard battery that has gone flat. I know that if this battery goes the machine may not boot at all.
Can you remember if your date and time was being kept accurately last time the machine booted? If you have had to reset the time and date a few times this would indicate the RAM battery going flat. Sorry can't help you with opening the iMac, I have no experience with this particular model but go to the following Apple link for instructions: http://manuals.info.apple.com/en_US/imacG5_allModels_BackupBattery.pdf Best of luck, Philippe Chaperon 2009/5/27 Mike Murray <[email protected]>: > Hi all > > Our sole remaining G5 iMac in the fleet has decided to play up. > > This morning when trying to wake it up as normal the screen remained black > and the fans started to roar.
