Beep Codes
Your computer might emit a series of beeps during start-up if the monitor cannot display errors or
problems. This series of beeps, called a beep code, identifies a problem. One possible beep code
(code 1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you
that the computer encountered a memory problem.
If your computer beeps during start-up:
1
Write down the beep code.

See "Dell Diagnostics" on page 30 to identify a more serious cause.

Using Microsoft Windows XP System Restore
The Microsoft Windows XP operating system provides System Restore to allow you to return your
computer to an earlier operating state (without affecting data files) if changes to the hardware, software,
or other system settings have left the computer in an undesirable operating state. See the Windows Help
and Support Center for information on using System Restore. To access the Windows Help and Support
Center, see "Windows Help and Support Center" on page 7.
NOTICE: Make regular backups of your data files. System Restore does not monitor your data files or recover them.
