7 Interpreting system validation diagnostic

front panel LEDs and audible codes

During the system validation phase that occurs at system startup, the BIOS validates the functionality of the

following subsystems and conditions:

●

AC adapter

●

System board power

●

Processor failure

●

BIOS corruption

●

Memory failure

●

Graphics failure

●

System board failure

●

BIOS authentication failure

If an error is detected, specic patterns of long and short blinks, accompanied by long and short beeps (where

applicable) are used to identify the error. These patterns will make up a two part code:

●

Major – the category of the error

●

Minor – the specic error within the category

NOTE: Single beep/blink codes are not used.

Number of long beeps/blinks Error category

1 Not used

2 BIOS

3 Hardware

4 Thermal

5 System board

Patterns of blink/beep codes are determined by using the following parameters:

●

1 second pause occurs after the last major blink.

●

2 second pause occurs after the last minor blink.

●

Beep error code sequences occur for the rst 5 iterations of the pattern and then stop.

●

Blink error code sequences continue until the computer is unplugged or the power button is pressed.

NOTE: Not all diagnostic lights and audible codes are available on all models.
