The power and battery-status light may blink amber or white according to pre-defined "beep codes" indicating various failures.
For example, the power and battery-status light blinks amber two times followed by a pause, and then blinks white three times
followed by a pause. This 2, 3 pattern continues until the computer is turned off, indicating no memory or RAM is detected.
The following table shows different power and battery-status light patterns and associated problems.
NOTE: The following diagnostic light codes and recommended solutions are intended for Dell service technicians to
troubleshoot problems. You should only perform troubleshooting and repairs as authorized or directed by the Dell technical
assistance team. Damage due to servicing that is not authorized by Dell is not covered by your warranty.
