Yesterday everything was fine with the battery in my MacBook Air 13'' 2012 (2 years old). It was lasting for 4-5 hours like new. Today, all of a sudden, the battery has stopped charging at all (I have only 40% left). While the power cable is plugged in, its LED doesn't indicate any colour. I rebooted the system, no difference. In System Info I have:
Cycle Count: 409 Condition: Service Battery
I heard that the lifetime of the battery should be 1000 cycles. I didn't update any software recently.
Does it all mean that the battery is dead? Or maybe there is a way to conquer it? Thank you!
