Diagnostics
Instead of beep codes, errors are indicated by the bicolor Battery Charge/Status LED. A specific blink pattern is followed by
flashing a pattern of flashes in amber, followed by white.
The diagnostic pattern consists 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 1.5 seconds.
The system will not shut down 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.
