I got my surface book a few days ago. I haven't noticed any issues mentioned in this forum yet. But I encountered strange behavior with mine. While I am actually using a surface book, I don't hear much of fan noise. It rarely comes on. However, when I tried to recharge it with a lid closed, surface book gets really hot and fan comes on. It keeps happening since yesterday. Do you have any suggestion? Once I open it, a fan stops. Thanks, guys.
