Hybrid sleep missing after Windows 10 anniversary update  

Have tried everything.

Please see http://windowsreport.com/hybrid-slee...ersary-update/.

Have tried what is on site and still do not see hybrid sleep as shown in screen capture above by philc43.

Anybody have any other ideas?

I think it is because you have the Surface Pro 4 which uses leading edge technology for the sleep states and I believe no longer uses the hybrid sleep mode. The Surface is in a class of devices that uses Modern Standby rather than traditional S1- S3 Sleep modes.

The W10 AU has no doubt improved the handling of these power states for your device.
