Battery status lights
If the computer is connected to an electrical outlet, the battery light operates as follows:
- Alternately blinking amber light and white light
- An unauthenticated or unsupported non-Dell AC adapter is attached to your laptop. Replug battery connector, replace battery if the issue recurs.
- Alternately blinking amber light with steady white light
- Temporary battery failure with AC adapter present. Replug battery connector, replace battery if the issue recurs.
- Constantly blinking amber light
- Fatal battery failure with AC adapter present. Fatal battery, replace the battery.
- Light off
- Battery in full charge mode with AC adapter present.
- White light on
- Battery in charge mode with AC adapter present.
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:
| Blinking pattern | Problem Description | Suggested Resolution | |
|---|---|---|---|
| Amber | White | ||
| 2 | 1 | processor | processor failure |
| 2 | 2 | system board, BIOS ROM | system board, covers BIOS corruption or ROM error |
| 2 | 3 | memory | no memory/no RAM detected |
| 2 | 4 | memory | memory failure/RAM failure |
| 2 | 5 | memory | invalid memory installed |
| 2 | 6 | system board; chipset | system board/ chipset error |
| 2 | 7 | display | display failure |
| 3 | 1 | RTC power failure | coin-cell battery failure |
