Troubleshooting

Tools

Power Lights

CAUTION: Before working inside your computer, read the safety information that

shipped with your computer. For additional safety best practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.

The power button light located on the front of the computer illuminates and blinks or remains solid to indicate different states:

• If the power light is blue and the computer is not responding, see "Beep Codes" on page 10.

• If the power light is blinking blue, the computer is in standby mode. Press a key on the keyboard, move the mouse, or press the power button to resume normal operation.

• 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.

– Bypass power protection devices, power strips, and power extension

cables to verify that the computer turns on properly.

– Ensure that the electrical outlet is working by testing it with another

device, such as a lamp.

– Ensure that the main power cable and front panel cable are securely

connected to the system board (see "System Board Components" on page 40).

• If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem may exist.

Troubleshooting 9

– Ensure that the voltage selection switch is set to match the AC power

at your location, if applicable.

– Ensure that the processor power cable is securely connected to the

system board (see "System Board Components" on page 40).

• If the power light is steady amber, a device may be malfunctioning or incorrectly installed.

– Remove and then reinstall the memory modules (see "Replacing or

Adding a Memory Module" on page 104).

– Remove and then reinstall any cards (see "PCI and PCI Express Cards"

on page 59).

• Eliminate interference. Some possible causes of interference are:

– Power, keyboard, and mouse extension cables

– Too many devices on a power strip

– Multiple power strips connected to the same electrical outlet

Beep Codes

Your computer may emit a series of beeps during start-up if the monitor cannot display errors or problems. For example, one possible beep code may consist of three short, repeated beeps indicating that the computer has encountered a possible system board failure.

If your computer emits a series of beeps during start-up:

Write down the beep code.

Run the Dell Diagnostics to further identify the problem. (see "Dell Diagnostics" on page 13).

• If two or more memory modules are installed, remove the modules (see "Replacing or Adding a Memory Module" on page 104), and then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error.

• If available, install working memory of the same type into your computer (see "Replacing or Adding a Memory Module" on page 104).

• If the problem persists, contact Dell (

"Contacting Dell" on page 137)

Contact Dell (see "Contacting Dell" on page 137).

• Ensure that no special requirements for memory module/connector placement exist (see "Replacing or Adding a Memory Module" on page 104).

• Ensure that the memory you are using is supported by your computer.

• If the problem persists, contact Dell

"Contacting Dell" on page 137).

• Replace the battery (see "Coin-Cell Battery" on page 117).

• If the problem persists, contact Dell
