As a result, users who have a dedicated GPU have been stuck on 1809 even as 1909 is in the final stages of prep for its release. This, of course, means an inability to get the latest security and OS features but is better than having a non-functioning graphics card. Thankfully, that’s no longer a compromise users need to make. As Thurrott reported on Friday, an update that fixes the issue is beginning to roll out to users. It appears to fix the issue once and for all while making additional improvements. Here are the changes you can expect:
“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.”
You can see the GPU fix under the Surface Firmware and UEFI upgrade, but also note the resolution of CPU throttling above. As we reported previously, this was caused by an Intel PROHOT flag, and Microsoft promised a fix in late September. Some users report that they got these fixes earlier via an Insider Slow Ring update. Generally, it’s vital Microsoft gets this out to Surface Book 2 users as quickly as possible, or it risks its own hardware being late to two feature updates. Issues like these often have to wait on a third-party for a resolution, which can take time. It’s not clear if that was the case here. Microsoft previously committed to update quality, but it’s clear there are still some issues if it can’t get a fix for its own hardware in a timely manner. Either way, you can grab the update via the usual channel, the Windows Update service. It’ll undoubtedly be a relief for those waiting on 1903’s Light Theme, sandbox functionality, or other features.
