Elitebook 820 G1

The laptop suddenly shuts down while in use and won't boot up again. Upon inserting the AC Adapter plug on the laptop it shows a series of blink codes right away even the power button is not pressed. The blink codes includes all LED lighting up then short Orange-White-Orange on AC Adapter/Battery Light LED. The code was different from what was posted on HP Website. https://www.youtube.com/watch?v=9aPz2GfWSgU
