NUC10i3FNK - Can't sleep with network cable plugged in -INCONSISTENT.

[entilza]

NUC10i3FNK - Does not sleep with network cable plugged in on first attempt. Sometimes works sometimes doesnt. Sreen goes blank all the time which is good but the device does not sleep.

On second attempt works.

Very inconsistent - I have 2 brand new NUC10i3FNK and I feel it has to do when network cable is plugged in.

On wifi it seems to be fine

Ok more info. I see the BIOS has "Modern Suspend" I have a feeling this is not working very well.

Unfortunately it says I have to re-install Windows if I change it. Wonderful after setting up 2 full NUCS I have to redo everything.

OK played with this some more. It seems the Modern suspend takes longer to operate.

However I also had issues when I try to sleep the computer from using tighvnc instead of being directly on pc. I'm not sure if it goes too fast or registeres the network connection and prevents sleep from activating.

It all seems related to network activity. This was never even noticed on the classic S3 suspend. So I am thinking this is some new behaviour.

Good news is by being left unattended it seems to go to sleep eventually.

Hello entilza

Thank you for posting on the Intel® communities.

In order to check this behavior further, could you please provide the following information?

1- Just to confirm, how many Intel® NUCs do you have experiencing this behavior?

2- Are you running any special network protocol on your environment? For instance network authentication or security protocols? Please provide details.

3- Since you mentioned that the system "by being left unattended it seems to go to sleep eventually." does this mean the issue only happens when you manually send the system to sleep?

4- Please provide details or screenshot of the changes you perform on the BIOS regarding "Modern Suspend".

5- By any chance and for testing purposes, have you tested with different network cables and/or different network devices?

Also, please run the Intel® System Support Utility (Intel® SSU) and attach the report to this thread to gather more details about your system.

1- Download the Intel® SSU and save the application on your computer.

https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-

2- Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".

3- To save your scan, click Next and click Save.

4- To attach a file, you must click the “Attach” option on the bottom left-hand corner of the response box.

Hey Andrew, Thanks for responding!

1. I have Two NUC10i3BNK that I felt were doing this.; It's very erratic. I thought just leaving them it was fine but what I noticed is occasionally the 'first' sleep command done even by clicking does not initiate. I get a black screen (monitor goes off) but a few times now the NUC never goes to sleep.

2. No special network, very basic. Ubiquiti switch/network. Simple stuff.

3. I was incorrect on this after more testing today

4. I just had the defaults "Modern"

5. I have not tested other network devices.

I wish I had more time on this but I am setting these up to go and I reverted back to "Legacy S3 suspend" And everything works as I expect. I did not re-install windows either it seemed to be ok.

Thanks for your response though, appreciate it.

Hello entilza

Thank you for your response and all the details provided.

We understand that the systems work fine after changing to "Legacy S3 suspend".

Also, we understand that you may not have time available to work on this further. We are wondering if the issue could be related to network packets being constantly sent through the NIC (network interface controller). Please let us know if you are able to provide us with the Intel SSU report so we can investigate this further.

Should you have additional inquiries, please do not hesitate to contact us back.
