Diagnostic LED
This section details the diagnostic features of the battery LED in a laptop.
Instead of beep codes errors are indicated via the bicolor Battery Charge LED. A specic blink pattern is followed by ashing a pattern of
ashes in green, followed by white. The pattern then repeats.
NOTE
: The diagnostic pattern will consist of a two digit number being represented by a rst group of LED blinks (1 through 9) in
green, followed by a 1.5 second pause with the LED o, and then a second group of LED blinks (1 through 9) in white. This is
then followed by a 3 second pause, with the LED o, before repeating over again. Each LED blink takes 0.5 seconds.
The system will not shutdown when displaying the Diagnostic Error Codes. Diagnostic Error Codes will always supersede any other use of
the LED. For instance, on laptops, battery codes for Low Battery or Battery Failure situations will not be displayed when Diagnostic Error
Codes are being displayed:
