Power Problems

Basic Checks:

• Test the electrical outlet: ensure that the electrical outlet is working by

testing it with another device such as a lamp.

• Connect the computer power cable directly to an electrical outlet:

bypass power protection devices, power strips, and extension cords to

verify that the computer turns on.

• Check for interference: electrical appliances on the same circuit or

operating in close proximity to the computer can cause interference.

If the problem still exists after you complete the basic checks, fill out the

Diagnostics Checklist as you perform the following steps:

1 Turn off the computer and devices, and disconnect them from their

electrical outlets.

2 If you are using a surge protector, remove it.

3 Make sure the power cable is firmly connected to the computer, and

then verify that the power cable is directly connected to the electrical

outlet.

4 Turn on the computer.

Does the power light on the front of the computer light up?

Yes. The problem is resolved.

No. The computer may be defective. Contact Dell for technical

assistance.

Video and Monitor Problems

Basic Checks:

• If the monitor power light does not light, check the power connection.

• If the external monitor is blank, the computer may be in suspend or

hibernate mode. To resume normal operation, press the power button.
