Driver PatchDay - LOL I love it. One thing I have found useful is to REMOVE / REBOOT / REINSTALL / REBOOT / CHECK using the drivers from Download Surface Pro 4 Drivers and Firmware from Official Microsoft Download Center - However since I installed Windows 10 "Redstone" all my sleep / hibernation issues have melted away. I can close my screen cover, open it, store it, open it, almost ZERO battery usage etc - whilst in transit / storage. I was seriously bummed out since last December when I got my screaming beast of a tablet, and almost opted for a fruity PC - but since I hate Apples, I stuck it out, and it seems Microsoft (at least for my machine) has hammered out the Power Issues. Yay -
