The Microsoft Surface Dock engineering team will soon be rolling out firmware support for Surface Pro X to enable users of the 2-in-1 device to directly run Microsoft Surface Dock Firmware Update. Currently, to update the firmware on Surface Dock, commercial customers can use any supported Surface device including Surface Pro 3, Surface Pro 4, Surface Pro (5th Gen), Surface Pro 6, Surface Pro 7, Surface Laptop, Surface Laptop 2, Surface Laptop 3, Surface Book, Surface Book 2, and Surface Go. The most recent Surface Dock firmware released in October 2019 added support for Surface Pro 7 and Surface Laptop 3.
At this time, running Microsoft Surface Dock Firmware Update on Surface Pro X generates the following error message: “This installation package is not supported by this processor type. Contact your product vendor.”
Upon conclusion of additional engineering work required to enable updating of ARM64 processor-based components, a new version of Microsoft Surface Dock Firmware Update will be released within the coming weeks. In the interim, Surface Dock will still run with Surface Pro X .
