I know the above has been discussed, I started syncing just a little bit ago with 92% on the battery meter, when it was done "long backup time" it was at 100%, so it must be charging despite the message next to the battery.
Why would it say not charging next to the battery icon? Perhaps it was a slow charge, later this evening, when I sync again I will leave it. It probably won't help to do a screen shot, but i will do one anyways.
Hmmmm charged/sync'd from a desktop powered USB hub while I was using the desktop... Said not charging but ended up charging. I will check later tonight, maybe it was a fluke.
