Creating System Restore Points

The Operating System CD may be required for these actions. However, procedures will vary.

For best results, attempt to recover optimal notebook functionality by using the following procedures in the order described here.

Safeguarding Your Data

Software or devices added to the notebook can cause your system to become unstable. To safeguard your documents, store personal files in the My Documents folder and periodically create a backup copy of My Documents. Setting System Restore points is also recommended.

Your notebook sets System Restore points (benchmarks) daily as you change your personal settings. The notebook may also set restore points when you add new software or devices. You should periodically set personal restore points when the notebook is functioning at optimal performance and before installing new software or devices. This enables you to return to a previous configuration restore point if you encounter problems.

To set a system restore point:

1.Select Start > Help & Support. Select the task Use Tools to view your computer information and diagnose problems. Select System Restore. A System Restore window opens.

2.Follow the on-screen directions for setting a restore point.
