MacBook keeps shutting down
I have a MacBook Pro 15" 2011, I have a couple of problems with it:
When I connect the MagSafe power adapters cable I have to hold the power button while I connect it for around 5 seconds then it turns on and if I just connect it and press the power button once or if I leave and leave the MagSafe on the computer it doesn't turn on.
If I turned it on, but when it does turn on it turns on once with a black screen then it will turn off then turn on a couple seconds later and the Apple logo will pop up and the bar will start too load and about halfway it shuts off then turn back on and go through the same problem overtime I've tried every reset even with the battery off and the MagSafe connected so I'm not sure if its the battery or motherboard or what.
Please help thank you
Is this a good question?
