Solid white – Power adapter is connected and the battery has more than 5 percentcharge.Amber – Computer is running on battery and the battery has less than 5 percentcharge.Off• Power adapter is connected and the battery is fully charged.• Computer is running on battery and the battery has more than 5 percent charge.• Computer is in sleep state, hibernation, or turned off.The power and battery-status light blinks amber along with beep codes indicatingfailures.For example, the power and battery-status light blinks amber two times followed by apause, and then blinks white three times followed by a pause. This 2,3 patterncontinues until the computer is turned off indicating no memory or RAM is detected.The following table shows different light patterns, what they indicate, and thesuggested solutions.Table 14.
