ThinkPad Power LED blink code

Axel Braun
Morning all,

I recently organized a Car adapter (12V input, 20V 4,5A output) for my T520.

If the T520 is connected to a power landline, the LEP is steady on while
charging. (ThinkPad not running, Sleep mode)

If connected to the Car adapter, the power LED blinks 3x short, 1x long.
(Yes, thats 'V' in Morse Code).
Anyone an idea what that should tell me?
