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