Microsoft this week shipped new firmware updates for Surface Pro (2017 and LTE) and the first generation Surface Book. It also issued a new version of the Surface Dock Updater software utility.

“We’ve released new driver and firmware updates for Surface Pro (Model 1796), Surface Pro with LTE Advanced (Model 1807) and Surface Book devices with Windows 10 Version 1703 (Creators Update) or above,” Microsoft’s Brandon Records explains. “On Surface Pro and Surface Pro with LTE Advanced devices, these updates include new Surface System Aggregator firmware. On Surface Book devices these updates include new drivers for Surface Integration and Surface Embedded Controller Firmware. These updates improve system stability and on Surface Book devices provide improved battery reliability.”

Here’s what’s new.

Surface Pro (LTE, model 1807)

Surface – Firmware – 233.2102.1.0. Surface System Aggregator Firmware – Firmware 233.2102.1.0 improves system stability.

Surface Pro (2017, model 1796)

Surface – Firmware – 233.2099.256.0. Surface System Aggregator Firmware – Firmware 233.2099.256.0 improves system stability.

Surface – System – 1.1.339.1. Surface Integration – System device 1.1.339.1 improves battery stability.

Surface Dock Updater

The Surface Dock Updater is made available via a multi-file download that Microsoft calls Surface Tools for IT. You can select which files you want to download; the update is named SurfaceDockUpdater_v2.12.136.0.msi.

“This new update includes fixes for external display stability issues when Surface Dock is used with Surface Book devices and includes firmware updates for both the Surface Dock main chipset and DisplayPort,” Records writes. “The updates provided by Surface Dock Updater v2.12.136.0 apply to Surface Dock only when used with Surface Book or Surface Book 2 and do not apply to scenarios where Surface Dock is used with other Surface devices. Surface Dock Updater firmware updates are cumulative. Updating a Surface Dock that has not yet been updated with v2.9.136.0 will provide the improvements of the earlier release in addition to those in v2.12.136.0.”

Improvements include:

Surface Dock Main Chipset Unit (MCU) Firmware v049E4970 improves display stability for external displays when used with Surface Book.

Surface Dock DisplayPort Firmware v049E3D71 improves display stability for external displays when used with Surface Book.
