Bought a replacement A1322 battery here on ifixit for my macbook pro, early 2011 model. I followed all instructions to install it.

I still have the same battery indicator in the menu bar that I had with the old battery: The icon shows the battery plugged in, with the words "(Not Charging)".

After reading a similar (though not identical) question and the answers that user got, I took the whole thing apart again, and checked: the connector is as tight as it should be, properly seated.

Also reset the PRAM and the System Management Controller (SMC). Still no battery charge.

The magsafe light is a steady green; no orange/red to indicate charging. The computer will not start without the magsafe power cord.

Any help will be very much appreciated!
