Windows PC wakes up from hibernation randomly (probably due to windows fileshare)

Hi,

I have three PCs. The main one (which I'm talking about) uses Windows, another Windows too. And the third one has dual boot - Windows and Linux.
On the main PC I have Win file share set up. Other PC's have the shared folders mounted.
Now what's the problem - when I put the main PC to sleep while any of the other PC's are still running (tried several times for both Win and Linux), the main PC randomly wakes up.
Tried powercfg /lastwake - it said it was my Ethernet card.
When I put the main PC to sleep after I shut down others, it doesn't wake up.
Is there a way to fix this without disabling WOL?

Hi @PetrKrautwurst-1866

Thank you for contacting Microsoft Open specification Support. After reviewing your question, it appeared your question does not fall under protocols guidelines outlined here https://aka.ms/openspecs. I will remove [openspecs-windows-filesharing]

Never-the-less, I found a following post that might help you find out what is causing it, Windows 10 randomly waking from hibernation. You can update this post with the Power Troubleshooter Result if need further assistance.

Hi @HungChunYu-3579

Thank you for your reply.
Unfortunately this doesn't solve my problem. I need WOL to work and the solution disables it too.

Were you able to identify which process/device is waking your computer?

Here is another post that might help, including not disabling WOL.

A bit late (forgot to reply here), but the "Only allow a magic packet to wake the computer" worked for me.
