Battery not charging on old non-unibody
Hi,
Just inherited an old MacBook Pro 15" non-unibody (A1211) from a friend. The original battery had stopped working, so I received it without one. Bought a cheapo on Amazon and it powered up, but when plugged in it displayed "not charging" by the battery life. Returned it and bought another less-cheap one. Same result. Friend says he never had that issue but that it did sit unused for about a year before I got it. Assuming it's computer-based at this point, and not two bad batteries in a row. I believe the charger is a non-Apple model, but again, worked fine before. Any ideas?
Thanks!
Update (12/18/2016)
I've also noticed that plugging/unplugging the charger results in brightening/dimming of the display, so it seems to at least recognize the charger...not sure if this helps anyone diagnose.
Any way to confirm that the charger is working properly? As I mentioned, it *was* working when it was put on the shelf a few years ago.
Is this a good question?
