Diagnostic LED
Occasionally the computer may indicate bicolor flashes on Battery Charge LED. A specific blink pattern, flashing a pattern of
amber, followed by white, and then the same pattern repeats.
NOTE: The diagnostic pattern consists of a two-digit number that is represented by a first group of amber LED blinks (1
through 9), followed by a 1.5-second pause with the LED off, and then a second group of LED blinks (1 through 9) in white.
Followed by a three-second pause, with the LED off, before repeating over again. Each LED blink takes 0.5 s.
The system does not shut down when displaying the Diagnostic Error Codes. Diagnostic Error Codes supersedes any other use
of the LED. For instance, on laptops, battery codes for Low Battery or Battery Failure situations are not displayed when the
Diagnostic Error Codes are being displayed:
