What Does a Continuous Beep Mean On a Computer?įor instance, a short single beep may be normal for some computers as they boot. Each error has its beep code, which also varies from BIOS to BIOS. If the POST finds everything OK, the OS boot process begins however, if the connected hardware is faulty, defected, or not found, the BIOS displays an error message/code stating the issue with a series of coded beeps. The POST checks the necessary hardware such as a processor, RAM, disk drive, and others before booting the OS. POST or Power-On Self-Test is a diagnostic testing sequence that system BIOS (Basic Input Output System) runs as soon as you power on a PC or laptop.
