My Macbook hasn't been able to be charged for a while now. Basically if you take the battery out while the computer is running and its plugged in, it will shut off but in a few seconds it lets me power it on without the battery in it.. So normally i just put the battery back in and leave it plugged in so the battery keeps its charge. It's been at 37% for a few weeks and will not charge up, it just looses power if disconected from the power cord. So when i go to system profiler it says, AC Charger Information: Connected: Yes Charging: No Anyone know how i could go about fixing this?
