Surface Laptop 3 15 gets a firmware update to improve battery life

If you've got the 15-inch flavor of the Surface Laptop 3, it's time to check for updates. Microsoft has new firmware rolling out for the device, specifically for the AMD-powered one. If you've got the Intel-powered Surface Laptop 3 15 for Business, or the Intel-powered Surface Laptop 13.5, there are no updates for you.

There's only one update and only one change, but it's a good one. This update is meant to improve system stability and battery life. Here's the changelog:

Windows Update History Name Device Manager Name Version and Update
Surface – Firmware - 1.2238.140.0 Surface UEFI – Firmware


  • improves system stability and battery life.

As usual, you can grab today's update from Windows Update, and it's available for all AMD-powered Surface Laptop 3 units with Windows 10 version 1903 or later, and since it shipped with version 1903, that's all of them. You can also download and install the firmware package manually if you want, and you can grab that here.
