Getting kind of desperate here, I am not expecting someone to know whats up, but i am looking for some ideas what might be causing this.
I went through 30+ forum posts with issues about PC waking up randomly, nothing helped. I narrowed it down that the wake up is probably cause by some kind of scheduler, tried deleting some, didn't help.
What i tried:
Disconnecting LAN and ALL USBs when my PC was sleeping.
Disconnecting Audio IN/OUT (LeL right?).
Disconnected monitor etc etc, my PC was purely clean except for power.
Checking out BIOS if there is an option to disable waking up (there is about USB and I have it disabled).
Disabled any option for any USB device to wake up PC.
Disabled possibility for PC to receive 'wake up requests' or w/e is it called, its in Power management advanced options.
Set some kind of weird 'Calm time' for whole day and every day (its a Win8 option, I randomly found it so I gave it a shot)
Deleted Win8 time scheduler.
Deleted some other random schedules, which ran at some point during/in between wake ups.
What I know:
Windows 8 'wake up reason' doesn't show a freaking sh*t, way to make a feature which actually doesn't work, it says "Unknown reason" (I think it also said somewhere BIOS clock synchronization, or something like that, but I figured it happens WHEN the PC wakes up and that it doesn't wake my PC); checked it in CMD as well as event viewer both said Unknown reason (no shiet when it's the same except graphical ^^)
Wakes up happen +- every 15 minute, sometimes 16 mins/14 mins, but its pretty much 15 mins, it just takes PC longer to boot up i think.
What am I looking for:
ANY POSSIBLE IDEA, I don't know what to do seriously
Decent event viewer, not the Windows poor one AND/OR somehow be able to check which event was run the first before wake up (meaning it woke up my PC)
EDIT:Also, i never really tested when the PC wake ups happen, but i know it stops at 22:00 and the wakes up happen BEFORE this time then it starts again sometime around 5:00. So luckily I can get some sleep, but it's pretty annoying when I go to sleep earlier than 22:00 lol
EDIT2:One more thing, I also would like to know some active forum which might be able to help me, never really posted anything like this so if anyone knows some good forum for this I would be glad for the info.
