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.

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.
