To perform the power supply self-test:
1 Turn your computer off and disconnect the computer from the electrical outlet.
2 Disconnect the DC power supply connectors from the system board and all internal devices. The procedure for disconnecting the power supply cables depends on the form factor of your computer:
• For the mini tower, see "Power Supply" on page 79
• For the desktop, see "Power Supply" on page 155
• For the small form factor, see "Power Supply" on page 219
3 Connect your computer to a working electrical outlet.
4 Press and hold the power supply test button.
– If the test LED illuminates, the power supply is functioning properly. Connect the DC power
supply connector to the system board, and then perform the test again. Continue to connect
devices (one at a time) and perform the self-test until the test LED fails to illuminate and a faulty
device is identified. Replace the defective device/part or contact Dell (see "Contacting Dell" on
page 370).
– If the test LED does not illuminate, the power supply is defective. Replace the power supply or
contact Dell (see "Contacting Dell" on page 370).
