Battery not being detected
My Macbook was running fine and then I put windows 10 on it and i didn't want it so i went back to mac and then It started not to get detected anymore.. I plug it in and turn it on and then remove the power cable and it stays on but it wont start without the power cable and it will have an X where the battery is?...... how do I fix this? do I have to download something or what? PLEASE HELP
