Thanks, you gave me the courage to fiddle with it more. I didn't dare continue the disassembly, but got it back together by opening the case halfway, so that the hinges lined up again, put in the screws, then closed it.

Would really like to see this part of the disassembly guide (steps 24-25) completed so that it shows the full set of steps. There were two little pieces on top of the hinges with screws also that had to come off, that are not shown in the disassembly at all. And the cable leading to the display is in the way of everything, with no explanation of how to lift it away safely.

Finally, I also didn't remove the motherboard, since the various little cable connectors have different locking mechanisms and it's hard to know where to spudge safely. Would appreciate more explanation there too.
