- The updates largely focus on battery improvements and fixes for major CPU and GPU issues with Surface Book 2.
Several Surface devices have firmware updates that improve battery life or battery stability. The Surface Book 2 (opens in new tab), Surface Pro 6 (opens in new tab), Surface Laptop 2 (opens in new tab), Surface Pro (5th Gen), Surface Laptop, and Surface Pro 4 all have firmware updates. The updates generally improve battery life or battery stability, but the Surface Book 2 updates in particular correct some major issues related to CPU throttling and the GPU going missing from Device Manager.
The Surface Book 2 has the longest list of changes.
- Surface Base 2 Firmware Update – Firmware
- 22.214.171.124 improves battery stability.
- Surface System Aggregator – Firmware
- 182.1004.139.0 resolves an issue where the CPU will throttle down to .4GHz, and improves battery stability.
- Surface UEFI – Firmware
- 389.2837.768.0 resolves an issue where the display adapter disappears from Device Manager.
The Surface Pro 6, Laptop 2, Laptop, Pro 5, and Pro 4 have all received updates that help improve battery life. Each carries a different version number, but they are nearly all updates to the Surface System Aggregator. The only exception is the Surface Pro 4, which improves battery life with an update to its Surface Embedded Controller firmware.
The firmware updates are available for devices running Windows 10 April 2018 Update, version 1803, or greater. You can find the full list of release notes for each device at the Surface Update History (opens in new tab) site.

I hope I can connect to my 5G Wi-Fi at home now without the wireless stack completely crashing after 5 minutes of use!
Battery improvements are always welcome!
Might be time to buy a Surface Book 2??
Can I now install version 1903 (May 2019 update)??
I have Surface book 2 (i7,512 ssd,1050) with all NEW firmware install BUT again nothing about 1903.
Shame Microsoft for your machine.
On my SB2 this morning it says it's not ready for 1903. As for the firmware update, I haven't seen these issues, but I'll take the update!
The great irony is that for me, my SB2 was stable, now, after the updates, it's crashing, blue screening (particularly when engaging the dGPU) and the battery life seems to have gone down.
No love for Surface Book 1? My battery No. 1 will not charge beyond 50% for the last couple of weeks and even though there are a good few people saying they have the same or similar problems there is no statement from Microsoft nor has anyone posted a fix or workaround.
