Microsoft has released a firmware upgrade for the Surface 3 that I am currently installing. I am hoping that the upgrade addresses a power issue I have where typically when there is about 20% of battery life left the Surface wants to forget that the type cover is attached, spitting out a USB device error.

Ok, it downloaded/installed some software, rebooted, and then blue-screened. It rebooted again, and now is installing a system update, which I assume is the firmware update.

The Surface 3 rebooted. All is well so far. After completing the update, my Surface 3 says that a driver update for the Intel HD Graphics was installed, and a System Firmware update from 8/8/2016 was installed. Interestingly, a System Hardware update dated 2/4/2016 was installed on 8/3/2016.
