This is the second machine I've seen in a week with the same problem, or at least very similar.
The one on my bench presently is an Elitebook 850 G8, the one I replaced a system board on was an Elitebook 845 G7. As soon as any type of power is connected, either battery or AC adapter, the charger LED will turn on white, but blink amber simultaneously. I believe it blinks 10 times. I have been unable to find any documentation for this specific error. This persists even if I remove connections from the system board to any other hardware aside from whichever power I am connecting. Even trying to power on with no RAM gives this error, will not beep/blink to indicate the system does not detect RAM. I do not even need to indicate power on for this to occur. As soon as there is enough contact with whichever connector to transmit the necessary power, it starts.
I have even tried running a BIOS recovery to no avail. This 850 G8 on my bench seems as though it will try to power, keyboard backlight will come up, Caps lock LED will light steady, no blink codes. It's under warranty, so ultimately it's probably going to get a new system board, but I want to know what this error is.
