Troubleshooting and Maintenance
Getting Assistance for Your Notebook
The hard drive's reported capacity is less than its actual size
• The hard disk drive is preconfigured to allocate some space to diagnostic software,
which is used in support and service of your notebook. This part of the hard drive is
unavailable for other uses, and so is not included in the capacity of the hard drive as
reported by Windows (My Computer, Properties).

Heat problems

Keep in mind that your notebook normally gets warm during routine operation. Charging
the battery and running games and other programs that drive CPU usage toward 100%
can further increase the notebook's temperature.
If the notebook gets warmer than usual
• Always set the notebook on a firm, flat surface, so that air can flow freely around and
underneath it.
• Make sure the air vents on the right side and back of the notebook are clear.
• Make sure the fan is working properly. If needed, test the fan's operation—see
"Testing the Hardware" on page 119.

Infrared Problems

If you have problems with infrared communication
• Make sure the line between the two infrared ports is not blocked, and that the ports
face each other as squarely as possible. The ports should be no more than 1 meter
apart, with no obstructions between them. Sunlight, heat from nearby equipment, and
other sources of infrared radiation can also cause transmission errors.
• Make sure only one application is using the infrared port.

Keyboard and pointing device problems

If the pointer is difficult to control
• Adjust the pointer controls: click Start, Control Panel, Printers and Other Hardware,
Mouse.
