  • Be sure to watch the wattage. I believe you need an 85W, not this 45W you asked the question on. It may work for a short time, but what will end up happening is you will actually slowly drain and kill your battery. I couldn't figure out why my MBP was killing batteries so quickly, about 2-3 months on average and then would also not run with the chord in -battery out- at all, until we figured out it was the underpowered power adapter. Each device uses a specific power adapter.
