 Power Button Light Codes
The diagnostic lights give much more information about the system state, but legacy power light states are also supported in your computer. The power light
states are shown in following table.
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.

 Beep Codes
If the monitor cannot display error messages during the POST, the computer may emit a series of beeps that identifies the problem or that can help you
identify a faulty component or assembly. The following table lists the beep codes that may be generated during the POST. Most beep codes indicate a fatal
error that prevents the computer from completing the boot routine until the indicated condition is corrected.

Light Pattern 

Problem Description

Suggested Resolution

The computer is in a normal off
condition or a possible pre-BIOS
failure has occurred.

l
l

 Plug the computer into a working electrical outlet.
 If the problem persists, contact Dell.

The diagnostic lights are not lit
after the computer successfully
boots to the operating system.
A possible processor failure has
occurred.

l

Memory modules are detected, but
a memory failure has occurred.

l

l

l
l

A possible graphics card failure has
occurred.

l
l
l

A possible floppy drive or hard
drive failure has occurred.

 Reseat the processor (see Processor information for your computer).
 If the problem persists, contact Dell.

 If 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.
 If available, install working memory of the same type into your computer.
 If the problem persists, contact Dell.

 Reseat any installed graphics cards.
 If available, install a working graphics card into your computer.
 If the problem persists, contact Dell .

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

l
l

Memory modules are detected, but
a memory configuration or
compatibility error has occurred.

l
l
l

A possible expansion card failure
has occurred.

l
l
l
l

Another failure has occurred.

l
l

 If 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.
 If available, install working memory of the same type into your computer.
 If the problem persists, contact Dell.

 Ensure that no special requirements for memory module/connector placement exist.
 Ensure that the memory you are using is supported by your computer (see the Specifications
section for your computer).
 If the problem persists, contact Dell.

 Determine if a conflict exists by removing an expansion card (not a graphics card) and
restarting the computer.
 If the problem persists, reinstall the card you removed, then remove a different card and
restart the computer.
 Repeat this process for each expansion card installed. If the computer starts normally,
troubleshoot the last card removed from the computer for resource conflicts.
 If the problem persists, contact Dell.

 Ensure that all hard drive and optical drive cables are properly connected to the system
board .
  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
l
l

You have performed the steps in Working on Your Computer.
You have read the safety information that shipped with your computer.
A component can be replaced or—purchased separately—installed by performing the removal procedure in reverse order.
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.

To avoid damaging your computer, perform the following steps before you begin working inside the computer.
1.
2.

Ensure that your work surface is flat and clean to prevent the cover from being scratched.
Turn off your computer (see Turning Off Your Computer).

3.
4.
5.
6.

Disconnect all network cables from the computer.
Disconnect your computer and all attached devices from their electrical outlets.
Press and hold the power button while the computer is unplugged to ground the system board.
Remove the cover.
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.
