Diagnostic LED
This section details the diagnostic features of the battery LED in a notebook.
Instead of beep codes errors are indicated via the bicolor Battery Charge LED. A specific blink pattern is followed by flashing a
pattern of flashes in amber, followed by white. The pattern then repeats.
NOTE:
The diagnostic pattern will consist of a two digit number being represented by a first group of LED blinks (1 through
9) in amber, followed by a 1.5 second pause with the LED off, and then a second group of LED blinks (1 through 9) in white.
This is then followed by a three second pause, with the LED off, 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 Notebooks, battery codes for Low Battery or Battery Failure situations will not be
displayed when Diagnostic Error Codes are being displayed:
