Forget the Genius Bar, infuse your MacBook Pro with new life while enabling the system to accept other upgrades by replacing the logic board with an Apple A1226 Intel (820-2101-A) logic board. Apple's patented term, 'logic board,' is the same thing as a more generic motherboard. Think of the logic board as the backbone of the Mac's system. It connects all the peripherals and different components, and it can make a significant impact on the system's performance. Other upgrades to consider include installing a faster processor, faster graphics card, increasing the system's memory, and using more external peripherals such as FireWire.
