Original Surface Book gets new firmware updates (October 2018) to support new battery limit feature

Microsoft is rolling out a number of new driver and firmware updates (October 2018) for the original Surface Book to support new battery limit feature and more.

Microsoft Surface Book Update

Recently, Microsoft has announced a new feature called “Battery Limit” for all recent Surface devices. The feature is an ideal power solution for Surface devices which are always connected to a dock or power supply. Last month, the company already released the firmware updates with the battery limit feature to  Surface Pro 3 and Surface Pro 4.

Yesterday, I’ve noticed my Surface Book also received a set of firmware updates, which aren’t listed on Surface Book Update History page yet. I have verified the updates, it does bring the “Battery Limit” support to my Surface Book as well.
