Hello,
I don't know if this has always been the case, and I've never noticed it before, but my surface book seems to be draining it's battery whist completely shut down.
I only just started taking notice because I thought it was my 'Surface Dock' not charging. I updated the dock to the latest firmware and thought that the end of the problems, but, alas no.
I jave got to do some more test but on first glance I think I might be loosing substantially more charge (whilst shutdown) thanĀ the reported 5-6% mentioned in some posts.
I have read through most post, and a few external links, am I right in thinking there is, as yet, not solution to this problem?
Thanks all
