Battery problem has been solved. I had 1 critical issue and 2 minimal ones on battery life. First and worst was pidgin. The software is very aggressive when the net goes down. RTComm beta is more 'quiet'. I use it ever 'on' autoconnecting when network is up. Pidgin, apparently, don't like this approach. Gnotifier also seems to be a battery eater, much less than pidgin. Last problem in my home network. I have 2 apple ap in a wds network (concrete building). If the tablet is left in the middle between the two ap, this seems to hamper battery life. No special ideas on the why. Just noticed it. I'm now happy again, with ca. 4 days standby with moderate use. I was just willing to share my findings in case someone else is hit, many thanks for your support in debug this. Tx, gt ps: the last strange thing is that the battery applet says: '8 days', goes down one day per day up to 4 and, then, the day after is empty. Not a big problem, in reality. Battery indicators are, in my experience, not more reliable in other cases (phones or notebook).
