Diagnostic Beep Codes
321722-001
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.
