MacBook Pro [15", mid 2010] battery not holding a charge
My MacBook Pro won't hold a charge. It only works with the magnetic cord connected. The power light won't turn orange, only green. At this point is it worth it to travel to an Apple store to have the battery replaced or attempt to buy one online and install it myself [I’m pretty handy]. I don't use it very often but I don't want to destroy it either. The hardware and battery information is as follows:
