Thanks for sharing your experiences with the recent, 4/19/2016, Surface updates. Please continue to provide this feedback - let us know if the updates helped address your concerns and challenges with waking your Surface.
Hi All,
We released an update on 2/17/2016 that addresses this issue.
We recommend that you install this update to keep your Surface performing its best. You can get updates now by checking Settings> Update & security> Windows Update.
To confirm the updates are installed, check Settings> Update & security> Windows Update> Advanced options> View your update history. If you locate updates with the status of "Requires restart to finish installing", please Restart (don't Shutdown) your Surface.
Example of update with status "Requires a restart to finish installing."

In certain instances the 1/27/2016 update did not install completely and is now causing the 2/17/2016 update to fail. To confirm the 2/17/2016 update successfully and completely installed, and to repair it if it did not please follow these steps.
1. Enter the words Device Manager into the search box on the taskbar, then select Device Manager from the list of results.
2. Expand the Firmware section.
a. If the items here do not have exclamation marks, the 2/17/2016 update is properly installed.
b. If the items here have an exclamation mark (see image below), please manually reinstall the 2/17/2016 update.
