Question

Basic input/output services (BIOS) Power-On Self-Test (POST) beep codes have been standardized so that if the computer emits a continuous beep (like a siren) upon startup, you know that the computer is reporting what condition?

Answer 1

A continuous beep sound during startup indicates a failed Power-On Self-Test (POST) in the computer. This usually points to a significant hardware problem.

Step-by-step explanation:

When a computer emits a continuous beep sound upon startup, it indicates that the Power-On Self-Test (POST) has failed. The POST is a series of diagnostic tests performed by the Basic Input/Output System (BIOS) to check if the computer's hardware is functioning properly.

A continuous beep usually suggests a significant hardware issue, such as a faulty memory module or a problem with the graphics card.
