===Resetting the Logic Board===
 +
Resetting the logic board can resolve many system problems. Whenever you have a unit that fails to power up, you should follow this procedure before replacing any modules.
 +
# Unplug the computer.
 +
# Remove the logic board.
 +
# Using a small flat-blade screwdriver, pry open the latch at the end of the battery holder and lift off the battery holder cover.
 +
# Remove the battery from its holder.
 +
# Verify the power supply cable is disconnected from the logic board and then press the Power On button.
 +
# Wait at least 10 minutes before replacing the battery. Make sure the battery is installed in the correct +/- direction.
 +
# Reassemble the computer and test the unit.
 +

'''Note:''' This procedure resets the computer’s PRAM. Be sure to check the computer’s time/date and other system parameter settings afterwards.
