The problem was that it always showed low battery. He took it to the Apple Store but it cost too much. They said it was the motherboard he asked me for help to buy a motherboard and replace it. We bought one but it still has the same problem I tried booting without it pressing keys and it boots without it. But the fan was working very fast processor heat a lot and also no integrated keyboard or trackpad work. Any help? Could it be that the Apple Store was wrong and it was not the motherboard?
