Computer wakes up seconds after it enters sleep mode.

Recently, whenever I put my computer into sleep mode it will turn on shortly after. Most times, I can hear my computer turn on as I am walking away. I know there may be similar posts, but none of them have solved my specific problem. I have already disabled the LAN setting "Wake on magic packet" and when I do the /lastwake command, it returns as an unknown type. I do not believe it is a wake timer, or an anti-virus scan as it will happen during any time of the day. Any help identifying what this unknown type is would be greatly appreciated, I hate having to turn my computer off after each use lol.

Can you tell us what kind of system you have...

Sorry, i'm running a CyberPower custom desktop with Windows 10 home, AMD FX 8320 CPU, Gigagbyte base board, 16GB ram, and GTX 1060 card. I recently upgraded to the GTX card, and replaced the power supply as well, perhaps this has something to do with the computer waking up?

ok give me a little bit to do some research and ill get back to you

ok so go ahead and put your computer to sleep and let it wake its self up

then right after it wakes up run cmd and type
powercfg -lastwake

make sure you run cmd as admin

actually if you go to your start menu and type in "event viewer" and open that you can probably see whats been waking up your computer in there

Thavks, I'll check as soon as I get back home, had to run my sister to work.

just got home. Put my computer to sleep and it woke up in about 30 seconds. running the lastwake command still shows the unknown culprit. However, a whole list has appeared in event finder, what do you make of this? Seems to be something with the power supply if i had to take a guess

You have not enabled power management relating to power saving or the settings, being set for suspend or sleep mode.

In the bios you will have a set of modes in the section of it listed for power or power management.

Acpi inside there are settings we call S or sleep state modes.
