- If the voltage is correct, replace the subcard.
- If the problem is not corrected, replace the system board.
- If the problem is not corrected, go to 'Undetermined Problems'.
- If the voltage is not correct, go to the next step.
Unplug the AC Adapter cable from the ac power outlet and wait
five minutes or longer to allow the over-voltage protection circuit
to be fully discharged and initialized.
Plug the AC Adapter cable into the ac power outlet.
Measure the output voltage of the AC Adapter.
If the voltage is still not correct, replace the AC Adapter.
