Microsoft finally fixes disappearing GPU issue on Surface Book 2, and CPU throttling issue

[zanderthunder]

 

For months, Microsoft has been blocking the Windows 10 May 2019 Update, or version 1903, on its own Surface Book 2 PCs. The reason was due to a known issue where the dedicated GPU driver would disappear from the Device Manager, leaving users to Intel's integrated graphics.

 

After the PC was blocked from installing the update since July, and it's been broken since May, it's finally getting fixed. Microsoft is pushing out a series of firmware updates that will fix that issue, among a couple of others.

 

Here's the full changelog:

 

Windows Update History Name	Device Manager Name
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.

The updates rolling out are for anyone that's running the Windows 10 April 2018 Update (version 1803) or later. After you install them, you should likely be offered Windows 10 version 1903.

 

It's possible that the feature update is still blocked for now, since it's still listed as a known issue that's being investigated on Microsoft's Dashboard for version 1903. This probably just hasn't been updated today, and should reflect the fix later on today or early next week.

The block on Surface Book 2 installing Windows 10 version 1903 has been lifted

 

 

Back in July, Microsoft stopped offering the Windows 10 May 2019 Update (version 1903) to its own Surface Book 2 PCs, due to an issue that caused the Device Manager to stop recognizing the dedicated GPU. In fact, the issue started up back in May, but it took until October to finally fix it with a firmware update.

 

At the time, the Windows 10 version 1903 known issues page, said that the block from upgrading to version 1903 would be lifted in the coming weeks. It's been 10 days since the fix was released, and the page now says that the "safeguard hold has been removed". It still might take up to 48 hours before you're offered the feature update.

 

Some users are already reporting receiving the update:

 

The news comes as the Windows 10 November 2019 is right around the corner. The good news is that Windows 10 version 1909 is just version 1903 with an enablement package to set up some minor new features. There shouldn't be any compatibility issues with this new update.

 

Thanks to Dr. Robert for the tip!
