Dock Works!!!!
OK very interesting update. The first time, when both dock and tablet were at 100%, the dock began to charge the tablet once it reached about 70%. Then when the dock was depleated, the keyboad did not work anymore. I also said when I undocked it and reconnected the keyboard had 7% left for some reason and continued to work. I just assumed it would stop working again as it drained. So I charged it all back up and ran the tablet for a little last night. Reached 70%, dock started charging the tablet and after the dock depleated to about 75%, I shut off the tablet for the night. I did not however plug it in. I noticed the dock was still charging the tablet so I assumed he dock would be dead the next morning. I didn't turn on the tablet untill now, (doing a ton of research at work on the dell venue.) I turned on the tablet and noticed the dock was at 0% BUT it is still working. I'm typing all of this right now using the dock and its at 0%. I don't know why it stoped working when it reached 0 yesterday but this is great news.
My new experiment will be to start all over again at 100%,, let the dock deplete, see if it stops working again and if it does, undock and redock to see if it continues to work. If not maybe just a reset will let it work again at 0%. If this is the case then I would consider the tablet not defective with the 2013.11 batch. The black squares I only noticed once in Chrome. I'm going to monitor the flickering. These issues have nothing to do with the dock.
