IF THE POWER LIGHT IS OFF The computer is either turned off or is not receiving power.

Reseat the power cable into both the power connector on the back of the computer and the electrical outlet.

If the computer is plugged into a power strip, ensure that the power strip is plugged into an electrical outlet and that the power strip is turned on.

Ensure that the electrical outlet is working by testing it with another device, such as a lamp.

Bypass power protection devices, power strips, and power extension cables to verify that the computer turns on.

Ensure that the main power cable is securely connected to the system board (see page 77).

Ensure that the front panel cable is securely connected to the system board (see page 77).

If the problem persists, contact Dell (see page 113).

IF THE POWER LIGHT IS STEADY AMBER The computer is receiving electrical power, but an internal power problem might exist.

Ensure that the microprocessor power cable is securely connected to the system board (see page 77).

Remove and then reinstall the memory modules (see page 95).

Remove and then reinstall any cards (see page 78)

If the problem persists, contact Dell (see page 113).

IF THE POWER LIGHT IS BLINKING AMBER A device might be malfunctioning or incorrectly installed.

Ensure that the main power cable is securely connected to the system board (see page 77).

If the problem persists, contact Dell (see page 113).

ELIMINATE INTER FERENCE Electrical appliances on the same circuit or operating near the computer can cause interference. Other causes of interference are:

Power extension cables

Keyboard and mouse extension cables

Too many devices on a power strip

Multiple power strips connected to the same electrical outlet
