Interpreting POST Diagnostic Front Panel LEDs and
Audible Codes
This section covers the front panel LED codes as well as the audible codes that may occur before or
during POST that do not necessarily have an error code or text message associated with them.
WARNING! When the computer is plugged into an AC power source, voltage is always applied to
the system board. To reduce the risk of personal injury from electrical shock and/or hot surfaces, be
sure to disconnect the power cord from the wall outlet and allow the internal system components to
cool before touching.
NOTE: If you see flashing LEDs on a PS/2 keyboard, look for flashing LEDs on the front panel of
the computer and refer to the following table to determine the front panel LED codes.
Recommended actions in the following table are listed in the order in which they should be
performed.
Not all diagnostic lights and audible codes are available on all models.
Table B-2 Diagnostic Front Panel LEDs and Audible Codes
Activity Blinks Possible Cause Recommended Action
Red Power LED flashes
two times, once every
second, followed by a two
second pause. Beeps stop
after fifth iteration but
LEDs continue until
problem is solved.
2 Processor thermal protection
activated:
A fan may be blocked or not
turning.
OR
The heat sink/fan assembly
is not properly attached to
the processor.
1. Ensure that the computer air vents are not
blocked and the processor cooling fan is running.
2. Open hood, press power button, and see if the
processor fan spins. If the processor fan is not
spinning, make sure the fan's cable is plugged
onto the system board header.
3. If fan is plugged in, but is not spinning, then
replace heat sink/fan assembly.
4. Contact an authorized reseller or service
provider.
Red Power LED flashes
three times, once every
second, followed by a two
second pause. Beeps stop
after fifth iteration but
LEDs continue until
problem is solved.
3 Processor not installed (not
an indicator of bad
processor).
1. Check to see that the processor is present.
2. Reseat the processor.
