A technician boots a desktop computer and hears a single, short beep. What does this typically indicate?
The motherboard has a critical error.
A memory module has failed.
The video card is not detected.
The system has successfully completed the POST.
A single, short beep during the Power-On Self-Test (POST) typically signifies a successful test, meaning the system's core hardware is functioning correctly. While specific beep codes can vary between BIOS/UEFI manufacturers, a single short beep is the most common signal for a healthy boot. Other beep patterns, such as multiple short beeps or a combination of long and short beeps, usually indicate specific hardware failures like issues with RAM, the video card, or the motherboard. Technicians should consult the motherboard's manual for precise beep code interpretations when troubleshooting.
