Hard drive problems

If the notebook hard drive doesn’t spin

•Make sure the notebook has power. If necessary, connect the AC adapter, and make sure it is fully plugged into a power source and into the back of the notebook.

•Remove and reinsert the hard drive.

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, and the disk you want to scan. Select File > Properties. Select the Check Now box under the Error-checking section of the Tools tab.

•Run the virus-scanning program.

•If necessary, you can format the hard disk and reinstall the original factory software using the QuickRestore System Recovery CD.

Heat problems

Your notebook normally gets warm during routine operation.

If the notebook gets abnormally hot

•Always set the notebook 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 notebook are clear.

•Keep in mind that games and other programs that drive CPU usage toward 100 percent can increase the notebook temperature.
