The problem occured after I formated laptop battery with Lenovo Energy Management. After battery charged 100% it started discharging. It discharged completly and laptop died. Laptop stopped detecting charger. When I unplug the charger and plug it back in again, the laptop doesn't detect it (it keeps on draining the battery and does't prompt that a charger is connected). To make the charger work, I have to do following actions: OS shut down battery removed charger unplugged from laptop and wall socket charger plugged to wall socket charger plugged to the laptop power button pressed once (laptop boots up) after succesfull boot I can put back the battery That is motherboard problem and i live in Kazakhstan, Kazakhstan doesn't have lenovo support center. And where to buy Lenovo Y580's motherboard?
