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 logic board. (Refer to the Take Apart chapter 

for instructions on how to remove the logic board.)

3 Using a small flat-blade screwdriver, pry open the latch 

at the end of the battery holder and lift off the battery 

holder cover.

4 Remove the battery from its holder.
