Hello all, I need some help, I have a 11 inch MacBook Air, and it’s not starting up at all, have a new cable, tried different plug sockets, and it’s been on charge since about 5pm and the light is still Amber, do you think there’s something wrong with the battery? I’m trying to pin point it but i have a sneaky suspicion might be battery? Even when it’s plugged in it won’t switch on. The last time it was working properly it was working perfect, next thing I knew it just didn’t work? Thank you!
