See "To protect against viruses" on page 41. • Test the hard disk drive with the e-Diagtools diagnostics. See "Testing the Hardware" on page 115. • If necessary, you can format the hard disk and reinstall the original factory software.

Infrared Problems By default, the infrared port is not enabled, so you must enable it before you can use it. If you have problems with infrared communications • Make sure the line between the two infrared ports is not blocked, and that the ports face each other as squarely as possible. (The computer's infrared port is located on the front of the computer.) The ports should be no more than 1 meter apart. • Check settings in the Device Manager: 1. Click Start, Control Panel, Performance and Maintenance, System. 2. On the Hardware tab, click Device Manager and expand the infrared devices.

Heat Problems
Your computer normally gets warm during routine operation.
If the computer gets abnormally hot
•
Always set the computer on a flat surface, so that air can flow freely around and
underneath it.
•
Make sure the air vents on the bottom and sides of the computer are clear.
•
Keep in mind that games and other programs that drive CPU usage toward 100% can
increase the computer’s temperature.
Infrared Problems
By default, the infrared port is not enabled, so you must enable it before you can use it.
If you have problems with infrared communications
•
Make sure the line between the two infrared ports is not blocked, and that the ports
face each other as squarely as possible. (The computer’s infrared port is located on
the front of the computer.) The ports should be no more than 1 meter apart.
•
Check settings in the Device Manager:
1.
Click Start, Control Panel, Performance and Maintenance, System.
2.
On the Hardware tab, click Device Manager and expand the infrared devices.
Double-click the infrared port and make sure that the device is enabled.
