B.1 Dell Optiplex® XE hardware common error indications
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.
