Diagnostic Beep Codes

The Power-On Self-Test (POST) is a series of diagnostic tests that runs automatically when the computer is powered on. If the POST detects an error, this causes an audible beep code to sound. The POST beep codes are not necessarily accompanied by an associated, visible error code or text message.

The following table shows the POST beep codes, their meanings, and the recommended actions for solving the problem.
