I agree that this entire procedure is unnecessarily complex, unless you’d like to disassemble your entire laptop for the sheer fun of it. The point of all the disassembly is to avoid damage to other components from the adhesive remover. So what I did was not to pry at all, no leverage whatsoever, no strain on the battery cells. Instead, I simply slid the provided plastic scraper cards underneath the batteries from every side possible to begin removing the adhesive. Then I put one drop of the remover on each side of the card at the front edge so it was barely wet, slid it in and worked it deeper bit by bit…. When I got near the speakers, I pulled the screws, lifted them slightly, and wedged one of the picks under the long arm coming off each speaker to give it a few mm clearance from the case, so no remover/alcohol could wick underneath. That worked well for me; the hardest part was getting all the old adhesive off the case, which just took some careful soaking. Good luck! .

Yeah. And if you've overheated your Dremel to the point where it quits running, the brushes may be melted in place. Disassemble the two halves of the case, and push against the brushes from the inside, using the armature. After they pop free, you'll probably find that your switch has melted as well. Return the whole thing to Dremel, and if they can't fix it cheaply, they'll give you a good deal on an upgrade to a newer model. Cheers!
