Hello Guys,
i got a faulty Lenovo S531 with a burned KB9012. I changed the KB9012, flashed the right Bios/EC File on it but he want turn on. I also changed the DC Board. When i press the power button, the fan starts to spin for 1 sec and then stops, also the keyboard light flashes on but immediately turns off. I couldnt find any schematic for this board. Does anyone have some information where i could begin to solve this problem? Or does somebody know from other Lenovo Boards what it could be? This Board has fixed soldered CPU and RAM, maybe my start problem could be a sign for a faulty CPU / RAM?
