Dreaming of an Affordable Surface Book 2 Laptop

Our national nightmare is (probably) over: After many long months, Microsoft has finally fixed a Windows 10 version 1903 blocking issue for Surface Book 2. The fix is part of a series of firmware updates that the software giant released just today.

Microsoft details the following updates for any Surface Book 2 running Windows 10 version 1803 or newer:

Surface – System – 1.75.139.0. Surface Base 2 Firmware Update – Firmware 1.75.139.0 improves battery stability.

Surface – Firmware – 182.1004.139.0. Surface System Aggregator – Firmware 182.1004.139.0 resolves an issue where the CPU will throttle down to .4GHz, and improves battery stability.

Surface – Firmware – 389.2837.768.0. Surface UEFI – Firmware 389.2837.768.0 resolves an issue where the display adapter disappears from Device Manager.

That last one, I believe, is the issue that blocked Surface Book 2 owners from getting Windows 10 version 1903. I will test this theory when I install the updates later today.
