well after months of my 2007 macbook pro giving me trouble with charging it finally died completely. nothing. ordered a new battery so i could start it up and get the model number and order a new I/O Power Board. am i wrong in figuring im going to need these numbers or is just knowing that its a 2007 enough to order a board, by the way the problem started with me having to wiggle the power corn at the connection to get it to charge, got worse over time. even replaced the charger.
