The power and battery status light indicates the power and battery status of the computer. These are the power states:
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 may blink amber or white according to pre-defined "beep codes" indicating various 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.
