Microsoft has finally patched an issue that some Surface Book 2 users have been facing over the last few months in which the processor would throttle at 0.4 GHz.
The company has released firmware updates for that issue, as well as a problem in which the GPU disappeared from the device manager.
The full changelog is available here (opens in new tab), and you can download the firmware here (opens in new tab). The firmware updates are for Surface Book 2 with Windows 10 1803.
An additional firmware update has been released to improve battery stability.
In theory, the GPU issue being solved should allow Surface Book 2 owners to finally upgrade to the latest version of Windows 10 (opens in new tab), version 1903, though we'll see what happens once a critical mass of Surface Book 2 owners get the new firmware.
