Resetting the Logic Board
Resetting the logic board can resolve many system problems 
(refer to “Symptom Charts” for examples). Whenever you 
have a unit that fails to power up, you should follow this 
procedure before replacing any modules. 
1 Unplug the computer.
2 Remove the battery from the logic board.
3 Disconnect the power supply cable from the logic board 
and then press the Power On button. (See “Logic Board 
Diagram” later in this chapter to locate the Power On 
button.)
4 Wait at least 10 minutes before replacing the battery. 
5 Make sure the battery is installed in the correct +/- 
direction.
