8.2 Blink and Beep Codes

Some system errors prevent the use of the video screen; instead, the system provides error information through blink

codes using LED lights. The LED light used depends on the system being a notebook or a desktop. The codes are presented

in a sequence. For desktop, this means red blinks followed by white blinks. Audible long and short beeps accompany red or

white blinks, respectively. The table below describes the meaning of critical blink codes.
