Dell XPS 210 - Manual (Page 51)

To help you troubleshoot a problem, your computer has four lights labeled 1, 2, 3, and 4 on the front panel (see Front View ). When the computer starts
normally, the lights flash before turning off. If the computer malfunctions, the sequence of the lights identify the problem.
Beep Codes
Your computer may 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. For example, beep code 1-3-1 (one possible beep code) 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.
NOTE: After the computer completes POST, all four lights turn off before booting to the operating system.
Light Pattern Problem Description Suggested Resolution
The computer is in a normal off
condition or a possible pre-BIOS
failure has occurred. l Plug the computer into a working electrical outlet (see "Power Problems" in your Owner's
Manual).
l If the problem persists, contact Dell (see "Contacting Dell" in your Owner's Manual).
A possible processor failure has
occurred. Contact Dell (see "Contacting Dell" in your Owner's Manual).
Memory modules are detected,
but a memory failure has
occurred. l If two or more memory modules are installed, remove the modules (see Removing Memory ), then
reinstall one module (see Installing Memory ) and restart the computer. If the computer starts
normally, continue to install additional memory modules (one at a time) until you have identified a
faulty module or reinstalled all modules without error.
l If available, install properly working memory of the same type into your computer (see Installing
Memory ).
l If the problem persists, contact Dell (see "Contacting Dell" in your Owner's Manual).
A possible graphics card failure
has occurred. l Reseat any installed graphics cards (see Cards ).
l If available, install a working graphics card into your computer.
l If the problem persists or the computer has integrated graphics, contact Dell (see "Contacting
Dell" in your Owner's Manual).
A possible floppy drive or hard
drive failure has occurred. Reseat all power and data cables.
A possible USB failure has
occurred. Reinstall all USB devices and check all cable connections.
No memory modules are
detected. l If two or more memory modules are installed, remove the modules (see Removing Memory ), then
reinstall one module (see Installing Memory ) and restart the computer. If the computer starts
normally, continue to install additional memory modules (one at a time) until you have identified a
faulty module or reinstalled all modules without error.
l If available, install properly working memory of the same type into your computer (see Installing
Memory ).
l If the problem persists, contact Dell (see "Contacting Dell" in your Owner's Manual).
Memory modules are detected,
but a memory configuration or
compatibility error has occurred. l Ensure that no special requirements for memory module/connector placement exist (see
Memory ).
l Ensure that the memory you are using is supported by your computer (see Memory ).
l If the problem persists, contact Dell (see "Contacting Dell" in your Owner's Manual).
A possible expansion card failure
has occurred. 1. Determine if a conflict exists by removing an expansion card (not a graphics card) and restarting
the computer (see Cards ).
2. If the problem persists, reinstall the card that you removed, then remove a different card and
restart the computer.
3. Repeat this process for each expansion card installed. If the computer starts normally,
troubleshoot the last card removed from the computer for resource conflicts (see "Resolving
Software and Hardware Incompatibilities" in your Owner's Manual).
4. If the problem persists, contact Dell (see "Contacting Dell" in your Owner's Manual).
Another failure has occurred. l Ensure that all hard drive and CD/DVD drive cables are properly connected to the system board
(see System Board Components ).
l If there is an error message on your screen identifying a problem with a device (such as the
floppy drive or hard drive), check the device to make sure it is functioning properly.
l If the operating system is attempting to boot from a device (such as the floppy drive or hard
drive), check system setup (see System Setup ) to make sure the boot sequence is correct for the
devices installed on your computer.
l If the problem persists, contact Dell (see "Contacting Dell" in your Owner's Manual).
