Hopefully Apple will release a nice update next month as my 2012 Macbook Pro needs replacing. I know Apple now solder Ram and SSD but do they also solder the battery in place and if so what happens when the battery starts to not hold charge as well or begins to fail? If they are like previous Macbook batteries after a few years they will probably need replacing but how do you do that? Does it have to go back to Apple for replacement? Pro machines are used constantly and being able to replace a battery without waiting days for a repair centre is important.
