Hey guys,
First of all, sorry for my poor English as I am from Hong Kong.
I wish my answer can still help someone who is encountering the problem as above including myself.
I had the exactly same issue as written above. Tried all means suggested by other people (reset SMC, changed new battery blah blah blah, I even '''replaced''' the ''logic board'') but with '''NO''' success. Lucky enough, I have another identical Macbook Pro (A1286, 15" late 2011), so I can exchange parts to see where goes wrong.
Eventually, it's the problem of Battery Indicator Lights (on the left hand side of MBP). I replaced a new one and now, my battery is BACK.
If you are not sure which part I am mentioning, it's here:

I wish this helps!
