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.
