Solved! Go to Solution.
The battery (it is yellow and rectangulat) from SBC board (that one where the network cable is connected) is drained and must be replace.
I dont have a video, but is simple to remove the board. Just loosen the 2 thumscrews (upper and lower), one thumbscrew at the handle and pull out the board.
