Microsoft surprised everyone the other day with a second Surface Pro 3 firmware update in September. Dubbed the September 29 release, the new firmware seems like a good one according to the changelog:
• 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 (v126.96.36.199) 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 (v188.8.131.527) improves the system stability.
Your Surface Pro 3 should have already received the update, but it never hurts to hit the “Check for updates” button to make sure. As always, you can head over to Settings > Update & Security > Windows Update, then click “Advanced options” and “View your update history” to check if the firmware update was successfully applied.
You can also check out Microsoft’s Surface Pro 3 downloads page to see if a firmware update is available for manual updating. As of now, it’s not, but Microsoft typically posts new firmware relatively soon after they’re available through Windows Update.Further reading: firmware update, Surface Pro 3
