The power and battery-status light blinks amber along with beep codes indicating
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.
