Surface Pro 4 and Surface Book take a long time to wake after February 2016 Windows updates are applied


After you apply the February 2016 Windows updates to a Surface Pro 4 or Surface Book, the device does not wake from sleep or it displays a blank screen after it wakes from sleep.

Customers may also see poor power performance or other symptoms after the updates are applied.

When this problem occurs, you see one or more of the following items in Device Manager marked by yellow exclamation points:

  • Surface Embedded Controller Firmware
  • Surface Management Engine
  • Surface System Aggregator Firmware
  • Surface UEFI


This problem can occur because an issue has prevented the firmware from updating successfully in the past.


To fix this problem, remove the failed firmware installation from Device Manager, and then manually reapply the latest firmware. To do this, follow these steps:

  1. Download the .msi file that contains the latest device firmware from the following Microsoft Download Center website.

  2. For each item that's listed in Device Manager as a failed device, uninstall the driver, and delete the driver files when you're prompted. Don't restart the computer yet.
  3. Run the .msi file that you downloaded in step 1 to reapply the latest device firmware.
  4. Restart the computer.

After you complete these steps, you should see the following firmware versions listed in Device Manager.
