When static, the power and battery-charge status light indicates the power mode that your computer is in. When blinking in different patterns, the power and battery-charge status light indicates the respective issues that your computer is encountering.
Static power and battery-charge status light
Power and battery-charge status light | Status of computer |
---|---|
Solid white |
|
Amber |
The computer is running on battery and the battery has less than five percent charge. |
Off |
The computer is in sleep state, hibernation, or turned off. |
Blinking power and battery-charge status light
The power and battery-status light blinks alternately between amber and off to indicate issues that your computer is encountering.
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 the different power and battery-status light patterns and the associated issues.
