Surface Pro 3 Gets A Second Firmware Update for September

With just a day left in the month, Microsoft has quietly squeaked out a second set of firmware updates for Surface Pro 3, improving … well, something. It’s not clear, as Microsoft has yet to actually document this update for some reason.

UPDATE: Now we know what changed:

Surface Pro System Aggregator Firmware update (v3.9.650.0) improves booting time experience and enhances the system reliability while docked.

Wireless Network Controller and Bluetooth driver update (v15.68.9030.41) improves the wireless network connectivity and stability.

Surface Integration driver update (v2.0.1209.0) ensures when using a custom power plan that the selected plan will not revert to the default balanced power plan when installing a Windows Update.

Microsoft Docking Station Audio Device driver update (v1.31.35.10) improves audio experience when no external speakers are connected to a Surface Pro 3 Docking Station so that Surface Pro 3 internal speakers are used.

Management Engine Interface driver update (v11.0.0.1157) improves the system stability.

You may recall that Surface Pro 3 was the only Surface tablet to get a firmware update this month, and that it only received a single update, for USB 3.0 card reader. (If not, check out Only Surface Pro 3 Gets a September 2015 Firmware Update).

With regards to today’s update, it’s described as System Firmware Update – 9/29/2015, and comes with no further documentation beyond “These updates are released by PC manufacturers to help improve the stability and performance of PC hardware.” I don’t know if it’s Windows 10 specific, or if you’ll get it with Windows 8.1 as well. According to a Windows Central reader, it includes updates to the “Intel MEI, Surface Integrator, WiFi and Bluetooth drivers, and System Aggregator Firmware.”

Should Microsoft actually explain itself, I’ll update this post. Until then I remain in the dark like everyone else, sorry.
