Power Light
State
Description
Off
Power is off, light is blank.
Blinking Amber
Initial state of light at power up.
Indicates system has power, but the POWER_GOOD signal is not yet active.
If the Hard Drive light is off, it is probable that the power supply needs to be replaced.
If the Hard Drive light on, it is probable that an onboard regulator or VRM has failed. Look at the diagnostic lights for further information.
Solid Amber
Second state of the light at power up. Indicates the POWER_GOOD signal is active and it is probable that the power supply is fine. Look at
the diagnostic lights for further information.
Blinking Green
System is in a low power state, either S1 or S3. Look at the diagnostic lights to determine which state the system is in.
Solid Green
System is in S0 state, the normal power state of a functioning machine.
The BIOS will turn the light to this state to indicate it has started fetching op-codes.

Light Pattern
Problem Description
Suggested Resolution
The computer is in a normal off
condition or a possible pre-BIOS
failure has occurred.
The diagnostic lights are not lit
after the computer successfully
boots to the operating system.
lPlug the computer into a working electrical outlet.
lIf the problem persists, contact Dell.
A possible processor failure has
occurred.
lReseat the processor (see Processor information for your computer).
lIf the problem persists, contact Dell.
Memory modules are detected, but
a memory failure has occurred.
lIf two or more memory modules are installed, remove the modules, then reinstall one module
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.
lIf available, install working memory of the same type into your computer.
lIf the problem persists, contact Dell.
A possible graphics card failure has
occurred.
lReseat any installed graphics cards.
lIf available, install a working graphics card into your computer.
lIf the problem persists, contact Dell .
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.
lIf two or more memory modules are installed, remove the modules, then reinstall one module
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.
lIf available, install working memory of the same type into your computer.
lIf the problem persists, contact Dell.
Memory modules are detected, but
a memory configuration or
compatibility error has occurred.
lEnsure that no special requirements for memory module/connector placement exist.
lEnsure that the memory you are using is supported by your computer (see the Specifications
section for your computer).
lIf the problem persists, contact Dell.
A possible expansion card failure
has occurred.
lDetermine if a conflict exists by removing an expansion card (not a graphics card) and
restarting the computer.
lIf the problem persists, reinstall the card you removed, then remove a different card and
restart the computer.
lRepeat this process for each expansion card installed. If the computer starts normally,
troubleshoot the last card removed from the computer for resource conflicts.
lIf the problem persists, contact Dell.
Another failure has occurred.
lEnsure that all hard drive and optical drive cables are properly connected to the system
board .
l If there is an error message on the 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
optical drive), check system setup to ensure the boot sequence is correct for the devices
installed on your computer.
lIf the problem persists, contact Dell.

WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best
practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.
CAUTION: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is
not covered by your warranty.
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal
surface, such as a connector on the back of the computer.
CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal
mounting bracket. Hold a component such as a processor by its edges, not by its pins.
CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors with locking
tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented
and aligned.
NOTE: The color of your computer and certain components may appear differently than shown in this document.
CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the cable from the network device.
CAUTION: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back
of the computer. While you work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal
components.
CAUTION: To avoid losing data, save and close all open files and exit all open programs before you turn off your computer.
Click Start® Turn Off Computer® Turn Off.
The computer turns off after the operating system shutdown process is complete.
2. Ensure that the computer and all attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut
down your operating system, press and hold the power button for about 6 seconds to turn them off.
After Working Inside Your Computer
After you complete any replacement procedure, ensure you connect any external devices, cards, and cables before turning on your computer.
1. Replace the cover.
2. Connect any telephone or network cables to your computer.
3. Connect your computer and all attached devices to their electrical outlets.
4. Turn on your computer.
5. Verify that the computer works correctly by running the Dell Diagnostics.
