Maintenance ----------------------------------------------------------------------------------

An important part of owning your computer is maintenance. With proper care, you can avoid common problems. The following sections provide information that can help you to keep your computer running smoothly.

General tips for maintenance

1Check the capacity of your hard disk drive from time to time. If the hard disk drive gets too full, Windows® will slow down and might produce errors.

2Empty your recycle bin on a regular basis.

3Use the Microsoft Disk Defragmenter on your hard disk drive on a regular basis to improve data seek and read time.

•To free up disk space, uninstall unused application programs.

•Clean out your Inbox, Sent, and Trash folders from your e-mail client program.

•At least once a week, make a point to back up your data. If critical data is present, it is a good idea to perform a daily backup. Lenovo has many backup options available for your computer. CD-RW drives or CD-RW/DVD drives are available for most computers.

•Use or schedule System Restore to take a system snapshot periodically.
