@morr22066: thanks for the hints!

I just bought a used n810 and have found the charger jack is unreliable.

I downloaded the service manual (thanks for the pointer). The process of replacing the jack looks intricate.

Removing the jack is step 21 in the disassembly process. Can some of the earlier steps be skipped?

Besides the Torx screwdriver, what other tools did you use? Did you have an SS-93 as used in disassembly steps 4, 9, 12, 13, 16, 17, 19, 25, 29, and 31?

Each screw that you remove is supposed to be discarded and replaced with new ones. Any idea why? Did you do that? Where would you get those screws?
