Today, after a week or two of light use (which is quite nice), I had to charge my Surface Book, so I plugged in the cable and put the computer to sleep by pressing the power button. A minute or two after that, the fans started to spin very fast. I touched the computer and noticed it was very hot. The weird thing is that if I exit sleep mode, or if I unplug the charging coord the temperture goes down quickly so the fans stop spinning but the second I plug the charger and put it to sleep it gets hot again and triggers the fans. I tried rebooting the computer but the problem was still there. I have no antivirus and no apps were running. Also, that's with the stable Windows 10 release and every updates installed, I'm not running insider builds. I had a big Windows cumulative update today so maybe that's what made the problem start (there was an update for the "Intel CSI2 Host Controller" among all updates) ? Anyone noticed the same problem ?
