If your computer makes one or two short beeps while starting, and Windows still opens, the
computer is indicating normal BIOS startup was successful. If your computer does not start, a
more serious hardware issue is likely occurring. Listen for beeps and look at the Light Emitting
Diodes (LEDs) near the Caps Lock key, the Num Lock key, the battery, and the AC Adapter to
help determine troubleshooting steps. This support document contains information that can
help you learn more about the issue and how to resolve the problem.
