Hey I opened up my N800, took the power connector port off and rebent the metal connector plates to fix my own. I guess after having the N800 fall off the edge of the couch while being charged enough times it just became too loose. The power connector is a tiny black box that can slip out from the case.

Maybe this is something you can fix on your own? I don't know what condition the kickstand is in but maybe there's another solution there.
