I didn’t make this post because I have a problem with my mini PC.
When I just got it I noticed it would automatically wake up a few minutes after putting it in sleep mode.
By using the hardware button to put the PC in sleepmode instead of using the sleep button on the Windows startmenu I get the desired behavior from the PC, it goes to sleep and doesn’t wake up by its self.
I read multiple posts from users wondering why their PCs would wake up/ fans starting to spin without any user input, so I though this post might be useful for some.
