NUC10i7FNB HDMI does not power up from sleep



my NUC doesn't reactivate the HDMI-Output after Windows 10 (20H2) suspend it by power saving settings.

The NUC is still operating, connecting via Remote is possible, but no more HDMI-Output.
The only way to get back a HDMI-Signal is sending to PowerSaveMode and restart from there with the powerbutton. A very unhappy workaraound.

Driver is actual :

Monitor is an HP27zn (2560x1440) which is runnig fine with other older NUCs

Thanks for any helpfull hint!

Hi Michael,

The default sleep mode in NUC FN is Modern Standby.  In my opinion, this mode is still not functioning well (I don't know if is from Intel or Microsoft  problem). Any way you may try to change the sleep mode to Legacy S3 Standby and see if this problem persists. In order to change the sleep mode without  corrupting Windows installation follow my instructions:

1. Prepare full backup image of your drive to be safe in case that something goes wrong.

2. While in Windows click on Windows key + R. Run msconfig command.  In the Boot tab enable SAFE boot. 

3. Reboot your NUC and while you see the Intel NUC logo, click on F2 to enter BIOS.

4. While in BIOS, click on Power tab and then on Secondary Power settings.

5. Set Sleep Type support to Legacy S3 Standby.

6. Click on F10, confirmed by "Yes" to save settings and exit to Windows.

7. While in Windows click on Windows key + R. Run msconfig command.  In the Boot tab uncheck the SAFE boot and reboot NUC.

8. Check how does it works. In the same way you may change the sleep mode back to Modern Standby if it doesn't helps.

Hi Leon

thanks for your reply!

The Bios is configured as S3 Legacy Standby so this problem seems to have an other reason.

The display was shut down after xx minutes by Windows Power Plan.
I've stoped the energy saving mode of the Display, to make sure that the problem is on the NUC side.

Today most times when WIN shut down the HDMI it will awake after about 3-5 sec. after keyboard or mouse action. But some times (and to often) nothing happens - although the system is running!

Hello mdPCP,  


Thank you for posting on the Intel® communities.   

In order to help you further, please try the following:

1. If using Windows® Operating Systems, check the Power Options on Power Options/Plan settings on Control Panel.

2. Check the Power Settings/Eco Mode on the TV/Monitor. For instructions on how to check these settings, contact the TV/Monitor manufacturer.

3. Load defaults settings in the NUC's BIOS:

- Press F2 during boot to enter BIOS Setup.

- Press F9 to set defaults.

- Press F10 to save and exit BIOS

4. If loading defaults BIOS does not help, check the power sleep states on the NUC.

Go to the BIOS and check the following settings:

- Advanced > Devices > Onboard Devices > Auto Turn On TV > Select "From S3/S4/S5 Boot".

TV turns on when Intel® NUC is powered on or resumes from S3/S4/S5 state.

- Advanced > Power > Secondary Power Settings (Right Section) > Deep S4/S5 > Select Disabled.

Disable to allow to wake up from other methods besides the power button.

- Advanced > Power > Secondary Power Settings (Right Section) > USB S4/S5 Power > Enabled.

Enable the USB Port power in S4/S5 state.

- Advanced > Power > Secondary Power Settings (Right Section) > Wake on USB from S5 > Enabled.

Enable Wake on USB from S5 state.

5. Check correct voltage memory: Use the correct voltage memory modules for your Intel NUC. To find the memory requirement for your Intel NUC, go to System Memory Information for Intel® NUC Products


6. Try to update the firmware for the HDMI.

7. If none of the above steps solve the issue, check that the NUC has the latest BIOS or try a BIOS recovery
