Surface Pro 4 firmware update adds power control slider to the system tray

A new batch of firmware updates is currently rolling out to the Surface Pro 4. And while there's no comprehensive set of release notes from Microsoft on the Surface Update History page just yet, there is at least one big change that's immediately noticeable: the addition of a slider control in the power performance pop-up (via Reddit).

Power Control Slider

The slider is available by clicking on the battery icon in the system tray. From there, you can adjust the power mode by sliding between "Best performance" on the right or "Best battery life" on the left, with options in between. This is the same type of slider that is currently available on the new Surface Pro and Surface Laptop.

Aside from the power slider, here's a look at the updates that appear as available in Windows Update:

  • Surface driver update for Surface Management Engine
  • Surface driver update for Surface Embedded Controller Firmware
  • Surface driver update for Surface UEFI
  • Surface driver update for Surface Pen Pairing
  • Microsoft driver update for Surface Accessory Device
  • Marvell Semiconductor, Inc. driver update for Marvell AVASTAR Bluetooth Radio Adapter
  • Intel Corporation driver update for Intel(R) HD Graphics 520,
  • Marvell Semiconductor, Inc. driver update for Marvell AVASTAR Wireless-AC Network Controller
  • Intel(R) Corporation driver update for Intel(R) Display Audio and Surface driver update for Surface Integration

Once Microsoft updates the Surface Update History site with full release notes, we'll add them here. For now, if you have a Surface Pro 4, you should be able to grab the latest firmware from Windows Update now.

Thanks to Dn Bianco and Chris K. for the tips!
