System diagnostic lights
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
The following table lists the status of your computer based on the power and battery-charge status light.
Table 19. Power and battery-charge status light
Power and battery-charge status light Status of computer
Solid white
● The power adapter is connected and the battery is fully
charged.
● The power adapter is connected and the battery has more
than five percent charge.
Amber The computer is running on battery and the battery has less
than five percent charge.

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.
