MAC - Bring A MAC Back From The Dead

Like many users, you may leave your Power Mac Dual G4 on indefinitely. However, an event such as a thunderstorm may shut it off for you. When you try to start it back up, you may notice that the button lights up when you press it, but then goes dim and nothing happens. A power outage can cause this sort of behavior.

Perform the following steps to reset your Mac:

  1. Unplug the power cable and all USB/FireWire drives and connections aside from the keyboard and mouse.
  2. Hold down the power button for 3 seconds to fully discharge any power on the logic board.
  3. Plug the power cable back in.
  4. Remove the lithium battery from the CPU.
  5. Reboot your computer.

The next time you shut down (without nature's help), you can put the battery back in.
