NUC8i7BEH BIOS 078 regresses to pre-073 monitor wake issues

[DElli23]

I installed the latest BIOS(078) and this has regressed the system to a pre-073 issue of the monitors not being able to wake up and requiring a system hard reset.

A downgrade to 077 does not fix the issue, I may have been on any BIOS between 073 and 077.

More than a little annoying.

I have tried various things that have been suggested before to no success. System was stable and functional before update and the BIOS was the only thing changes at that time.

HDMI firmware was already up to date.

As pre-077 BIOS downloads do not seem to be available does anyone have any suggestions other than format system and switch to Legacy Boot?

Hello DElli23

Thank you for posting in the Intel Community.

I would recommend trying these steps when an Intel NUC does not come back after going to sleep mode.

1- ​​​​​​If the issue occurred after any recent software, Operating System update, hardware or BIOS changes, try to undo those changes.

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

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

4- Load defaults settings in the NUC's BIOS:

a- Press F2 during boot to enter BIOS Setup.

b- Press F9 to set defaults.

c- Press F10 to save and exit BIOS.

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

Go to the BIOS and check the following settings:

a- 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.

b- Advance > Power > Secondary Power Settings (Right Section) > Deep S4/S5 > Select Disabled

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

c- Advance > Power > Secondary Power Settings (Right Section) > USB S4/S5 Power > Enabled

Enable the USB Port power in S4/S5 state.

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

Enable Wake on USB from S5 state.

For more information regarding Intel NUC's BIOS settings, please refer to BIOS Settings Glossary for Intel® NUC

6- 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

7- Check with the TV/monitor manufacturer for firmware updates that might help to solve the issue.

8- Test the NUC with minimal configuration by removing all non-necessary components like USB devices, external hard drives, adapters and use only wired mouse and keyboard. This may help to diagnose if the issue is related to a particular component connected to the NUC.

9- If using a graphics driver version higher than 25.20.100.6519, roll it back to this specific driver version. It has been reported that this driver version fixes wake up issues.

10- If none of the above steps solve the issue, make sure the NUC has the latest BIOS or try a BIOS recovery. 

NOTE: the BIOS options are the once on the Intel download center

1- ​​​​​​If the issue occurred after any recent software, Operating System update, hardware or BIOS changes, try to undo those changes.

Would do, but the earlier BIOS is not available to download any more.

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

And do? They are in a standard monitor off after X that was previously working.

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

None on these screens

4- Load defaults settings in the NUC's BIOS:

Done, no change.

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

Tried, no change.

6- 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

These are all at defaults and the memory is compatible.

7- Check with the TV/monitor manufacturer for firmware updates that might help to solve the issue.

N/A - These monitors are from before that was a concern.

8- Test the NUC with minimal configuration by removing all non-necessary components like USB devices, external hard drives, adapters and use only wired mouse and keyboard. This may help to diagnose if the issue is related to a particular component connected to the NUC.

Only has wired keyboard and wireless keyboard / mouse attached. Have checked without the wireless one. No change.

9- If using a graphics driver version higher than 25.20.100.6519, roll it back to this specific driver version. It has been reported that this driver version fixes wake up issues.

The suggested driver is not compatible with Win 10 1909.

10- If none of the above steps solve the issue, make sure the NUC has the latest BIOS or try a BIOS recovery. 

This was the cause of the problem in the first place.

I would also add, it is only the monitors sleeping. The unit itself is set to sleep well beyond the time set for the monitors to turn off.

More Details:

I have tried:

1) Different monitors.

2) Different cables, including HDMI converters

3) 1 and 2 monitors at a time.

4) Full power down and re-plug of the system.

5) Different peripherals

6) Re-flashing the hdmi Firmware

I have also found that it appears to be a whole system crash about 2 mins after the monitors go dark. Prior to that there is a lot of HDD access. I can not find anything useful in the Event log at these times.
