This is essential to any operation involving removing the top case as it is attached to the battery's housing. Therefore, I need a way to release the battery or to remove the top case without removing the battery; I am willing to risk damage as the macbook is completely useless with the present hard drive.
Do you know a course of action that can allow me to proceed to get into my macbook?
p.s. As I am not under warranty, I can't involve Apple in this - I can't afford to pay someone £70 an hour, sadly. (by the way, I'm clearly in the wrong job).
