POST beep codes

A beep code is a combination of short or long beeps or series of short beeps that

are separated by pauses. For example, a “1-2-3” beep code is one short beep, a

pause, two short beeps, and pause, and three short beeps. A beep code indicates

that POST has detected a problem. If no beep code sounds, see “No-beep

symptoms” on page 152.

The following table describes the beep codes and suggested actions to correct the

detected problems.

A single problem might cause more than one error message. When this occurs,

correct the cause of the first error message. The other error messages usually will

not occur the next time POST runs.

Exception: If there are multiple error codes that indicate a microprocessor error,

the error might be in a microprocessor or in a microprocessor socket. See

“Microprocessor problems” on page 178 for information about diagnosing

microprocessor problems.

v Follow the suggested actions in the order in which they are listed in the Action column until the problem

is solved.

v See Chapter 3, “Parts listing, TD100 Types 6398, 6399, 6419, 6429, 4203, and 4206,” on page 25 to

determine which components are customer replaceable units (CRU) and which components are field

replaceable units (FRU).

v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a

trained service technician.
