•Solid Amber — The system board cannot start initialization. There may be a problem with either the system board or power supply.

•Blinking Amber — The computer has detected an error during POST. The light will flash along with the three BIOS beep codes to indicate the error.

•Blinking White — The computer is in sleep state. Press a key on the keyboard, move the mouse, or press the power button to resume to normal operation.

•Solid White — The computer is fully functional and is in S0 (ON) state
