I lifted the battery out from the computer twice. Now what? I used the spudger and I can't bloody well remove screws that are already removed, can I? Reverse order my eye! Then I caught my dick in the fan. These instructions are impossibly difficult! Thanks a lot!!

Where do you purchase a replacement battery? And just what is a spudger anyway? It is not on your list of things to purchase so where do I get one?

You don’t really need a spudger. A guitar pick or even a flathead screwdriver (if you’re careful) can work, although in my personal experience just being careful while prying it out is perfectly fine. It’s used so you don’t rip off the little plastic clips that hold the bottom chassis together.
