MacBook Pro 6,2 won't run off of a fully charged replacement battery.

I replaced the battery in my 2010 UNibody 15" Macbook pro. The replacement battery has fully charged, but the computer won't fun off of the battery.

When it's plugged in, the batter indicator lights as well as apps like Battery Monitor show a full charge and perfect battery health. However, as soon as I unplug the power cable, the computer shuts down, just as if i didn't have a battery in the machine.

I've tried both an SMC reset as well as a PRAM reset. No joy - any suggestions?

Answer this question I have this problem too

Is this a good question?

Sadly, your systems power logic on the main logic board is having problems switching between the two power sources. One of the MOSFETs has failed and will need to be replaced. This often happens in this series.

Time to find someone with good micro soldering skills to fix your logic board.

So, i guess i'm basically looking at a motherboard replacement? So, even though it was able to CHARGE my battery, it's unable to USE the power from the battery?

No, you need to get your logic board fixed, not replaced.
