Hard disk drive problems

If the notebook's hard drive doesn't spin
• Make sure the notebook has power. If necessary, connect the AC adapter, and make
sure it is plugged securely into a power source and into the back of the notebook.
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 the fan.
If files are corrupted
• Run the Norton AntiVirus program—see "To protect against viruses" on page 41.
• Check the hard disk: open My Computer, select the disk you want to scan, then click
File, Properties, and use the Tools tab.
• Test the hard disk drive with the e-DiagTools diagnostics—see "Testing the
Hardware" on page 100.
• If necessary, format the hard disk and reinstall the original factory software—see "To
recover the factory installation of your hard disk" on page 104.
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 for 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 abnormally hot
• Provide adequate ventilation around the notebook. Make sure there is adequate
clearance at the back of the notebook, so that its fan vent is not blocked.
