Surface Pro X day-one firmware updates improve stability

Yesterday, Microsoft released the Surface Pro X, the first Surface device running Windows 10 on an ARM chipset, specifically the Microsoft SQ1, which is a slightly customized version of the Snapdragon 8cx. Now, the company has added the Pro X to the Surface update history page, along with the first list of firmware updates for it.

The updates are available for those running Windows 10 version 1903 or later, and they'll show up as a single update in Windows Update, which is somewhat unusual. This might be because ARM chipsets usually include many of the hardware components the device runs on, so a single update package can deliver updates to multiple components. Here's what's new:

Microsoft Corporation – System Hardware Update – 11/05/2019

Device Manager Name

Surface UEFI– Firmware

  • 3.444.140.0 improves system stability.

Surface System Aggregator – Firmware

  • 14.57.139.0 improves battery performance.

Surface Pro X Integration – System devices

  • 20.63.139.0 improves stability when in hibernation.

Microsoft SQ1 Adreno 685 GPU – Display Adapters

  • 26.18.800.0 improves system stability.

Surface Pro X Power Engine Plug-in Device

  • 1.0.0800.0 improves system stability.

The updates focus mostly on improving stability and battery performance, which is usually the case with firmware updates. One interesting tidbit is that the changelog indicates the Microsoft SQ1 chipset has an Adreno 685 GPU, where the Snapdragon 8cx has an Adreno 680. This is similar to how the "Surface Edition" Ryzen processors in the Surface Laptop 3 have slightly different GPUs from the regular versions of the same processors.

If you're one of the early adopters of the Surface Pro X, you'll want to check Windows Update to get the latest updates and get the best experience.
