It has been a few days since my last post and I continue to have problems with the camera. After a period of inactivity, the Surface will not unlock using Windows hello. It just refuses to wake up or even give you the option to use a password/pin. If you disconnect it from the dock you can sometimes git it to log back on but at other times you either have to hard boot or it just restarts. Just this morning after jut 10 minutes of inactivity the screen would not unlock and then it blue screened with stop code error - iacamera65,sys failed. This all points to an issue with the camera but the drivers/firmware are all up to date.
