I am almost exclusively running unplugged, and if I am plugged in I am actively working on my SP7, so, every time it has happened has been on battery power. But that is not to say, it can't happen plugged in, I just haven't had a chance to test it yet.
May do so later today.
The customer service person I am working with is having me do a full thumbdrive factory reinstall of everything next, having already done a system reset and it not helping. I am suspecting it will not work. But will post an update here when I get the chance
to go thru the steps.
It is all somewhat annoying, because this computer is so new, and it works while I am using it, but I know it will turn into a bigger problem if I don't address it, all these system restores are aggravating, I have set up a new computer 3 times already in
1 week of owning the thing. And I just got a new desktop a few months ago as well, so I am tired of installing my software. But I will get to it later on today when I get out of work. And update what progress I have if any.
