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. (See Take 

Apart for instructions on how to remove the battery.)

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. 

Make sure the battery is installed in the correct +/- 

direction.
