Microsoft is working to resolve CPU throttling on the company's latest Surface devices, and owners also complain about Wi-Fi issues. A Microsoft spokesman said in a statement in TechRepublic “Some customers are reporting scenarios on Surface Books that are slowing down the CPU. "We're trying to fix it quickly with a firmware update."
According to various complaints about Redit, CPU throttling seems to affect both Surface Book 2 and Surface Pro 6. As the processor shrinks to 400 MHz, the cause of the problem is not immediately apparent. TechRepublic reported that throttling appears to be locked by the Intel CPU flag accidentally, causing the throttle because it thinks the CPU is at thermal limits.
The latest firmware update from Microsoft, along with CPU issues, caused some Wi-Fi issues. Surface Book and Surface Pro 6 owners have complained about the Microsoft support forum that the latest Marvel Wi-Fi driver that came with Microsoft's Surface firmware update on August 1st says that the device cannot connect to some 5GHz wireless networks. You've encountered these issues on your Surface Pro 6 device, and it's likely a problem with a specific router combination.
You can roll back the driver if there's a Wi-Fi issue on your Surface device since the update earlier this month. Restore access to your 5 GHz network in Device Manager. One of our Microsoft volunteers claimed that the company was "updating." I've requested feedback on a Wi-Fi issue.
Some weeks after Microsoft stopped releasing the Windows 10 May 2019 update for Surface Book 2 devices, the latest issue occurs. The owner reported a problem with the Nvidia GPU disconnection, and Microsoft is now working on a fix to make the update available again. Microsoft's Surface devices have been highly reliable in recent years due to a wide range of issues with the first Surface Book and Surface Pro 4 in 2016.This has caused consumer reports for all Surface hardware. The "recommended" badge has been removed. Restored after one year.
