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?
