Troubleshooting and Maintenance Troubleshooting Your Computer If the hard disk makes a buzzing or whining noise • Back up the drive immediately. • See whether the noise is coming from elsewhere, such as from the fan or a PC Card drive. If files are corrupted • Open My Computer, select the disk you want to scan, click File, Properties, and use the Tools tab. • Run the virus-scanning program. See "To protect against viruses" on page 42. • Test the hard disk drive with the e-Diagtools diagnostics. See "Testing the Hardware" on page 146. • If necessary, you can format the hard disk and reinstall the original factory software. See "To recover the factory installation of your hard disk" on page 154. 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 right side 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 its right side, beneath the volume control.) The ports should be no more than 1 meter apart. 130 Corporate Evaluator's Guide
