Floppy Drive

NOTICE:

Do not attempt to clean drive heads with a swab. The heads may become misaligned and prevent the drive from operating.

Clean your floppy drive using a commercially available cleaning kit. These kits contain pretreated floppy disks to remove contaminants that accumulate during normal operation.

CDs and DVDs

NOTICE:

Always use compressed air to clean the lens in the CD/DVD drive, and follow the instructions that come with the compressed air. Never touch the lens in the drive.

1

Hold the disc by its outer edge. You can also touch the inside edge of the center hole.

NOTICE:

To prevent damaging the surface, do not wipe in a circular motion around the disc.

2

With a soft, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line from the center to the outer edge of the disc.

For stubborn dirt, try using water or a diluted solution of water and mild soap. You can also purchase commercial products that clean discs and provide some protection from dust, fingerprints, and scratches. Cleaning products for CDs are safe to use on DVDs.

Power Lights

CAUTION:

Before you begin any of the procedures in this section, follow the safety instructions in the

Product Information Guide

.

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 green and the computer is not responding, "Diagnostic

Lights" on page 26.

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

Quick Reference Guide

• 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" in your

User’s Guide

).

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

– 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" in your

User’s Guide

).

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

– Remove and then reinstall the memory modules (see "Removing the

Front Panel" in your

User’s Guide

).

– Remove and then reinstall any cards (see "Cards" in your

User’s Guide

).

• 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
