First of all: I could not find info about the NUC's front LEDs behavior meaning it entered in 'Sleep Mode':
- Blue Frame and OnOff On;
- Blue Frame on; OnOff Blinking Blue;
- or Blue Frame off; OnOff blinking amber ?
Another: when plugged, but off, the LED is a steady amber; shouldn't it be also OFF?
Obs.: I also have a Intel Compute Stick STK2m3W64CC (I deeply regret this line discontinued) and the LED goes blinking amber, when in Sleep Mode; and off, when OFF.
I have a backlighted keyboard (Kinesis Gaming Freestyle Edge) attached to the NUC
When I go: Start Button > Power > Sleep, just the Monitor is turned off; the keyboard's LEDs are still on; NUC's lights all on (sometimes, OnOff blinking). And it 'wakes up' almost instantly (that's a good thing)
I ran a 'energy report' by typing "powercfg -energy" into the command prompt (at administrator level).
Attached is the energy-report.pdf, showing some issues that may be causing the not-sleeping.
- Power & Sleep are configured to NEVER (like both my other Win 10 computers, with no sleep issues)
- All drivers dutifully updated
And please clarify the expected LEDs behavior.
UPDATE (I couldn't stop tinkering...) : it was 'Intel Ready Mode' that was preventing the Sleep. Once I disabled it, my NUC managed to sleep, as expected (with a blinking amber LED, as should)
But I will look into this brand-new app I didn't know about, and bundled installed and enabled -- 'https://www.intel.com/content/www/us/en/architecture-and-technology/intel-ready-mode-technology.html Intel Ready Mode' -- later. Good to know.
(I considered deleting this topic, but I think this information could benefit other users with the same problem)
Anyway: if some new app -- that radically modifies a computer expected behavior ! -- is pre-installed and running in the background, It would be advisable to notify the user about this new feature!
Thank you for posting on the Intel ® communities.
I would like to thank you for leaving a feedback about this situation. This could be pretty helpful for other community members that may be experiencing a situation like this.
