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. 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. Chapter 6. Troubleshooting 75
