Brand new 8920, Win 10 Pro + creators update. DIdn't test it prior to creators. Checked all the settings in control panel -> power options, they seem to be set correctly for my wanted time out. The display will go to sleep, and the screen saver password will lock as well after X amount of time. But the system itself won't spin down the disks and sleep no matter what time length I set it to. I can't seem to find any application that would be keeping it on. Also weird is that I can force sleep by manually selecting sleep from Start button -> shut down -> sleep, which works fine. Event Viewer isn't really providing anything useful.

Thanks Dell folks.
