Beep Codes
When POST finds an error and cannot display a message, the computer's speaker emits a series of beeps to
indicate the error. For example, video failure or configuration error is indicated by a 1 - 2 beep code (a
burst of three beeps , one long beep followed by two short beeps).
The following table lists other fatal error and their associated beep codes.
Each code represents the number of short beeps that are grouped together.
Fatal errors (errors that lock up the computer) are generally the result of a failed main logic board or some
other add-on component (SIMM, BIOS, computer battery, etc.).
