General tips for maintenance

1 Check 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 Diskeeper Lite or 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.

Note:

You might also want to look for application program duplication or overlapping versions.

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 and CD- RW/DVD drives are available for most computers and are easily installed.

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

Note:

Always take a system snapshot before installing new drivers, updating software, or installing new software.

Update device drivers and BIOS when needed.
