System diagnostic lights
Power and battery-status light
Indicates the power and battery-charge status.
Solid white —Power adapter is connected and the battery has more than 5% charge.
Amber —Computer is running on battery and the battery has less than 5% charge.
Off
● Power adapter is connected, and the battery is fully charged.
● Computer is running on battery, and the battery has more than 5% charge.
● Computer is in sleep state, hibernation, or turned off.
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.
The following table shows different power and battery-status light patterns and associated problems.
