Yes, it does. In fact, this is really the way I can still use it. When it is running, it will rarely charge. If I unplug either the a/c at the mains, or at the computer, it will show a charge for a few seconds, and then quit.

When I shut it off, it may or may not start to charge. I sometimes have to recycle it many times to get it to stay charging. It does not seem to be a loose connection at power jack however.
