Power Supply Shutdowns

Power Supply Shutdowns

If the power supply shuts down, or appears  to fail at power-on, you might have one of the following problems:

Unplug the power cord and wait two minutes before checking voltages to give the power supply capacitors time to discharge.

NOTE: Verify that the voltage-select switch (if applicable) is set for the correct voltage.

If the voltages are correct and the Symptom-to-FRU index does not solve the problem, go to Undetermined Problems on page 183 in the PS/2 Hardware Maintenance Manual.
