Great instructions.
Now to find a M6091 main battery.
does a lubricant help reduce the tension on the screen mounts. ? I read these easily break.

I lubricated my screen hinges some years ago. It did help, but I should probably do it again. I think I used a very thin silicone or aromatics WD-40 type of spray, and carefully attempted to pry open the gap of the hinge to facilitate the ingress of the lube, maybe using an Opinel knife or a Stanley blade. Apologies for flaky memory. My hinges are still a dangerously weak point, and I always open the laptop carefully and slowly with two hands. Good luck.
