Amber LED State Description

3,6 possible system board resource and/or hardware failure

3,7 some other failure with messages on screen

Beep Code

The computer can emit a series of beeps during start-up if the display does not show errors or

problems. These series of beeps, called beep codes, identify various problems. The delay between each

beep is 300 ms, the delay between each set of beeps is 3 sec, and the beep sound lasts 300 ms. After

each beep and each set of beeps, the BIOS should detect if the user presses the power button. If so,

BIOS will jump out from looping and execute the normal shutdown process and power system.

Code 1-3-2

Cause Memory failure

NOTE: 1. If the system is attached with an internal speaker we can hear the beep sound directly.

NOTE: 2. If the system does have an internal speaker, connect an external speaker to line out

connection to hear the beep sound.

NOTE: User can also check the power LED behavior instead of the beep code for troubleshooting

purpose.
