POST beep codes
One beep and the appearance of text on the monitor indicate successful
completion of POST. More than one beep indicates that POST detected an
error.
Beep codes are sounded in a series of two or three sets of beeps. The
duration of each beep is constant, but the length of the pause between the
beeps varies. For example, a 1–2–4 beep code sounds like one beep, a
pause, two consecutive beeps, another pause, and four more consecutive
beeps.
It is possible to misinterpret beep codes if you do not understand exactly
how they work. Keeping in mind that POST beep codes vary in the length
of the pause, and not the duration of the beep tones, will help you to
distinguish the beeps.
For the following beep codes, the numbers indicate the sequence and
number of beeps. For example, a “2–3–2” error symptom (a burst of two
beeps, three beeps, then two beeps) indicates a memory module problem.
