It's apparently been lingering from 51% to 70% from last night to this morning, but ever since installed snow leopard (clean install) I plug in my charger and it says "Not Charging". I installed all the updates software/firmware that I can, and nothing seemed to help.

Someone suggested I recalibrate my battery but I calibrate it at least every month and I just did it a few weeks ago. Also, how does one recalibrate a battery that wont charge?
It's a newish battery, and also there is no way I can afford a new one any time soon. My charger is fine, and I've never had any issues until I installed Snow Leopard last night.
