I have observed something strange recently and I have absolutely no idea if this has been true in past firmware revisions or is related to the power drain issue. When I powered off my n800 last night because the battery was low I had the alarm set. Typically, I wake up 5 minutes before the stupid thing goes off so I didn't worry about it. This morning I woke up as usual and at about 2 minutes before the alarm was set to go off, the N800 actually switched itself on (from a power off state) and the alarm sounded (although not the music file I had previously set). I wonder if the power issue was somehow related to the machine trying to save enough power to allow something like this to happen. And if this is well known or has already been reported than I apologize for wasting your time=)
