i bought a wireless keyboard off craigslist, little did I know, it is a broken one. somehow, the battery terminal snapped off. I am trying to solder it back on, however, i am having a bit of an issue with the disassembly. i followed the guide at iFixit.com Link. But i am stuck on step number 7. Doesn't matter how i poke at the battery terminal, it just refuses to come out. Any ideas on how to approach this?
