System diagnostic lights
Power status light: Indicates the power status.
Solid Amber – The computer is unable to boot to the operating system. This indicates that the power supply or another device in the
computer is failing.
Blinking Amber – The computer is unable to boot to the operating system. This indicates that the power supply is normal but another
device in the computer is failing or not installed properly.
NOTE: See the light patterns to determine the device that is failing.
Off – Computer is in hibernation or turned off.
The power status light blinks amber along with beep codes indicating failures.
For example, the power status light blinks amber two times followed by a pause, and then blinks white three times followed by a pause.
This 3,3 pattern continues until the computer is turned off indicating the Recovery image is not found.
The following table shows different light patterns what they indicate, and the suggested solutions:
