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.
If the following beep codes occur, have the computer serviced.
Beep code Probable cause
1–1–3 CMOS write/read failure
1–1–4 BIOS ROM checksum failure
1–2–1 Programmable interval timer test failure
1–2–2 DMA initialization failure
1–2–3 DMA page register write/read test failure
1–2–4 RAM refresh verification failure
1–3–1 RAM test failure
