Interpreting POST diagnostic front panel lights and audible codes

This section identifies the front panel light codes as well as the audible codes that can occur before or during
POST that might not have an error code or text message associated with them.

CAUTION:

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 AC outlet and allow the internal system components to cool before touching.

NOTE:

If you see blinking lights on a PS/2 keyboard, look for blinking lights on the front panel of the computer

and see the following table to determine the front panel light 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.
