My lenovo g500 is at 62% but once I remove the adapter, it goes off. Please can u help me. Ac adapter works perfectly but once I remove the adapter, I can't on the laptop while battery is connected. It all started when I had power failure and my laptop went off even though the power was at 74% at the time. Now it won't even turn on while on battery but once I connect the ac adapter, it powers buy shows battery is charging but goes off again once I take out adapter. Please I really need your help.
