Hi,
this battery drain bug has been pestering me since I did the first SSU (to version 30-2) on my N800. No similar symptoms before the upgrade. In order not to go insane because of the present unreliability of my N800 I'm trying hard to pin down the bug with a hardware current monitor attached to the battery. I posted a HOWTO guide on that topic in the hope that it may turn out helpful to "the IT community". See my post in the other battery thread:
