I have been a user of this feature for some years but am struggling to get the behaviour I want with tmy MSI H610-mDDR4.
I have recently changed the intergrated LAN adapter power management setting of the above from on to off. This change was to try and control the behaviour of the PC in that it was wakingup throughout the day and night for no reason - I had tried all of the usual tricks and even with the lan disconnected it would wake up and once the sleep timer expired it would sleep again. Fast start up, timers, usb powwer management settings....no effect. I turned off "allow the computer to switch this device off" in the belief that the other options (only allow a magic packet to wake) would exercise control. However the LAN port had no power under this setting and would not wake from magic packet.
I see a setting in BIOS/Advanced/ wake up event which offers a choice of bios or OS - can anyone explain the function of this setting ?
thanks
I've answered my own question - Wake Events by OS control will disable PCI-E (lan) wake up so back to drawing board and experiments with existing settings.

Is there a "wake on pattern match" option? If so make sure it's disabled. On my system, if that's enabled I get the same behavior you describe above.

Resolved "spurious" wake ups. Because I use the PC as a HTPC, it has to perform wake-ups to record programmes.
The on-board "clock" wakes the system up to check the time as it can drift away from reality - and potentially miss a recording event.
It then goes back to sleep after the "sleep after" time has expired - all good for me now
