It has 86 charge cycles and is 22 months old. When i plug the adapter in it says not charging. There is a green light however. I check the battery status and it says Condition : Replace Now. But this seems weird because a normal battery lasts 400 cycles at least. I'm not very sure what the problem is, the battery or the charger? And if it's the charger, would changing a whole new adapter work? Thanks.
