Hi there, I am planning to get a new MacBook Pro 13" model. I have some questions to ask regarding long hours of usage. Right now, with my current PC laptop, I am able to remove the battery to run it on AC mode so I can leave it on for hours without having to charge the battery. As with the new MBP, the battery are in-built and if I wanna run it on AC mode, it will inevitably charge the battery. I know the old MacBook Pro allows you to pluck out the battery so you can run it on AC mode. Any solutions for this? Please advise.
