Hard disk drive problems
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 computer. 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).
If the computer’s hard drive doesn’t spin
•
Make sure the computer has power. If necessary, connect the AC adapter, making
sure it is plugged into a power source and into the rear of the computer.
If the hard disk makes a buzzing or whining noise
•
Back up the drive immediately.
•
Check for alternate noise sources, such as the fan or a PC card drive.
If files are corrupted
•
Run the virus-scanning program.
•
Check your disk using error-checking (open My Computer, select the disk you want
to scan, click File, click Properties, select the Tools tab, and click Check Now).
•
Test the hard disk drive with diagnostics. See “Testing Hardware Operation” on
page 111.
•
If necessary, format the hard disk and reinstall the original factory software—see “To
recover the factory installation of your hard disk” on page 113.
Heat problems
Your computer normally gets warm during routine operation.
If the computer gets abnormally hot
•
Always set the computer on a flat, firm surface, so that air can flow freely around and
underneath it.
•
Make sure the air vents are clear.
