Basics Resetting the Logic Board - 24
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.
