My G5 is not booting up and it sounds like an airplane taking off. I replaced the 3.6V battery, but it did not correct the problem. Any suggestions??
PowerMac
Try a Safe Mode boot (hold Shift while starting).
Remove and reinstall the RAM.
Resetting the Logic Board
Resetting the logic board can resolve many system problems. Whenever you have a
unit that fails to power up, you should follow this procedure
before replacing any modules.
1 Unplug the computer.
2 Press the Power On button on the front of the unit.
3 Open the side access panel.
4 Remove the battery from the logic board.
5 Wait at least 10 minutes before replacing the battery.
6 Make sure the battery is installed in the correct +/-
direction.
7 Reassemble the computer and test the unit.
Cheers, Tom 😉
I am having the same problem as you Sheba62. I have replaced the battery, and done a logic board reset (done twice. First time it worked about a month ago. Second time, today, failed), but to no avail. The computer still will not boot (no chime, fans accelerate faster after 10 or so seconds).
