Beep symptoms

See > No Beep symptoms

Beep symptoms are short tones or a series of short tones separated by pauses (intervals without sound).
See the following examples.

Note: One beep after successfully completing POST indicates the system is functioning properly.

Beeps	Description
1-2-3	° One beep
	° A pause (or break)
	° Two beeps
	° A pause (or break)
