Ok, HERE IS THE SOLUTION (waiting for the official fix): you have to restore the driver called "Surface Pen Setting".
This will fix the blue death screen and the Restart button (didn't test the battery yet).
About the Windows 10 refresh: God, it seems so hard! Is there an easy guide for dummies to follow?

"Thanks for all that have provided responses for this blue screen "DRIVER_POWER_STATE_failure" issue. With your help we were able to identify the source of the issue being the Surface Pen Settings driver (version 10.0.302.0 dated 10/22/2015) which was inadvertently being installed as part of the ?System Firmware Update ? 1/19/2016? or manually installed by some customers.
This driver is not intended for Surface Pro 3 and is no longer being offered as part of the update. If you had manually download and installed the Surface Pen Settings driver from the Surface Pro 4 Drivers page in an effort to enable Surface pen button customization through the Surface app on Surface Pro 3, you will need to roll back and remove the driver.
We are sorry for any confusion or inconvenience that this has caused.
[Update added 10/27/2016 by Jerry]
Today we re-released the Surface System Update from 1/19/2016. This update now includes a Surface Pen Settings driver (version 4.0.112.1 dated 1/23/2016). Installing the ?System Hardware Update ? 1/19/2016? will remove the 10.0.302.0 version of the Surface Pen Settings driver if it is installed on your Surface. The 10.0.302.0 version resulted in ?DRIVER_POWER_STATE_FAILURE? BSOD issue as well as Surface randomly waking from sleep and long boot times associated with this driver being installed. Installing the ?System Firmware Update ? 1/19/2016? or ?System Hardware Update ? 1/19/2016? and then restarting (not shutdown) Surface should resolve these issues if it was associated with the Surface Pen Settings driver.
Below are the manual steps to remove version 10.0.302.0 of the Surface Pen Settings driver on your Surface Pro 3, in the event you are unable to install the re-released version of ?System Firmware Update ? 1/19/2016? or ?System Hardware Update ? 1/19/2016?.
1.Restart (not shutdown) Surface.
2.Right click the Windows Start Menu icon and click Device Manager.
3.Click the arrow next to Human Interface Devices to expand that node.
4.Double-click on Surface Pen Settings.
5.Click on the Driver tab to view the version information.
6.If the version of the driver is 10.0.302.0, please click Uninstall.
7.In the Confirm Device Uninstall popup, check the box to "Delete the driver software for this device" and click OK.
8.Restart (not shutdown) Surface.
9.You should now have the Surface Pen Settings driver version 4.0.112.1 dated 3/30/2015. "
If you either roll back the Pen Settings driver or run the latest Firmware Update, your problem is fixed.
