Thanks, downloading it now... swupdate.jpg
Done and installed. The serial connection shows a little less spurious activity, but unplugging it is the only way to check the battery life since it is also a charging cable. My ONLY reason to download any update is battery life. Nothing else matters whatsoever. So I am hoping for the best and expecting to be somewhat disappointed.
