Hi all, i recently got my macbook back after having the top case replaced. My battery does not appear to hold any charge at all anymore. I've charged the battery up but as soon as i remove the power cable the battery completely drains straight away. There is a green light that flashes on the back of the battery when the power cable is connected, does this mean there's an issue with the battery or just that the battery is charging? Does anyone know what the issue would be with my battery not holding charge? Considering it was very good before i sent macbook off to get fixed i find it hard to believe the battery would suddenly become a dud in the space of 5 days. Any info appreciated.
