Unable to display sleep or activate screen saver

[larrikinaus]

I have an ASUS Z97 Pro Wifi AC motherboard.

I am running 10.11.5 El Capitan.

Under Energy Saver, I have the display sleep set to 15 minutes but the display is never put to sleep. Nor is the screen saver activated after 10 mins.

This shows up in console, not sure if its related:

kernel[0] <Notice>: [HID] [ATC] AppleDeviceManagementHIDEventServicerocessWakeReason Wake reason: Button (0x03)

I've googled that message but cannot find anything relevant - very little information available.

Kext patches installed are the USB Series 7,8,9, USB Expansion patch, and the BT / WIFI patches. I have also installed sensors patch so I can monitor hardware. I use an iMac 14,2 profile.

Any ideas on what I can do to troubleshoot this please?

I should add that when I ran a Mac Pro 3,1 SMBios profile, Energy Saver did work. It was when I changed to the iMac 14,2 profile that it stopped. I don't want to go back to a Mac Pro 3,1 SMBios profile given the amount of people who told me I should change, and also due to impending Sierra not supporting Mac Pro 3,1.

I can't explain why, but I am delighted to say that this problem as been fixed by following this guide to fix iMessage. Clearly it has had something to do with fixing my energy saving as well!!!
