Purchased a brand-new ASUS X570 F motherboard with CPU, Memory etc. all new.
My problem is the system, while in stand-by will randomly turn on for a few minutes and turn itself back off. Even if it comes out of standby and I start using it browsing the web, watching video etc. it will still go back to standby after that same five minutes. I tried disabling WOL to no avail, what gives?
This one took a bit more research and will require trying several things to see what helps. The first thing to do is to use the PowerShell in admin mode and type "powercfg -lastwake". This will show you what is making your computer come out of sleep mode, results will show everything from power button to the actual device ID like a keyboard or mouse.
Another option is to unplug the mouse and keyboard when you put the machine to sleep to see if these devices are getting vibrations, especially the mouse, causing the wake situation.
It's also important to note that some installed security software will wake your machine to check for updates. It's worth a try to enable hibernation and put the computer in deep sleep.
