From what we've seen in the movies, the entire planet seems to have landing pads and such throughout the upper levels. If they've got a sizable fraction of the planet's surface area usable as a spaceport, distributed throughout essentially the entire planet, any logistical problems would not come from getting things between the spaceports and where they are needed.
This strikes me as extraordinarily foolish. It's not that hard to have a hard shutdown mode in which most of those parasitic loads are gone and trigger it if the battery charge drops bellow a certain level. We've had that technology in laptops for quite a while. This is not a hard problem to solve, and it is obvious enough that it should have occurred to someone. Also, monitoring the current it is getting for charging and displaying a warning if it is insufficient and perhaps a projected charging time would be a good feature.
I suspect that any truly adequate automated essay grader would imply strong AI or at the very least some optimization process good enough that it might as well be strong AI.

Here's a heuristic: Questions of the form "I'm 17. Should I drop school for X?" should be answered in the negative for essentially all plausible values of X.
