Glad to hear it's working well!

I can't remember if I ever shared this bug I've experienced with the WD15. I've found that when I unplug my laptop (closed, as it always is when docked), it seems that the XPS 13 doesn't go to sleep properly. I'll throw it in my bag and when I pull it out later it's burning up and the battery is dead. What I have to do instead is unplug it, wait a few seconds, open the screen, then close the screen again. Then I can safely put it in my bag. It's annoying but not terrible.
