We encountered an error while trying to save the changes. We've made a note of it, and we'll fix the problem as soon as possible.
...It's almost exactly the same as our old, "lesser" MacBook Unibody.
The battery compartment is identical to the one we uncovered in the MacBook Pro 17" Teardown. We'll venture a guess that it looks the same in the updated 15" Pro as well.
Remove two tri-wing screws and the battery is suddenly replaceable. The sticker comes right off, just as in the 17" Pro -- because it's adhered to just the battery and midwall, not to the optical drive.
