Macbook Pro Battery not recognized even after replacement
I purchased my MBP in late 2011. a couple weeks ago my battery stopped being recognized and i went to the genius bar. they wanted me to pay $129 for a battery replacement but i instead purchased my battery from amazon. same EXACT battery. and it still doesn't work. any suggestions?
MacBook Pro (13-inch Late 2011), Mac OS X (10.7.4)
