So, I have a pretty new laptop, and one of its quirks is that, at random times (though typically in the middle of the night), it seems to wake up from sleep mode, churn a bit, and then go back into sleep mode. I write "seems" because its fans are very loud, so it's obvious when it's not asleep, but during the time it is "on", I can't see anything on the screen.
I have researched the problem somewhat, and could only find similar issues; nothing identical. In those cases, it appeared that certain devices could be responsible. Nothing is plugged into my computer during this behavior, but I nonetheless disabled every device's permission to wake the computer through the device manager. This included disabling the magic packet wake for the network (despite its only having a wireless connection). Using "powercfg /lastwake" gives an empty wake history. But, I also went through all the tasks and checked if they would wake the computer. None appeared to.
The problem persisted, so, after some more research, I found this, and executed it for all power schemes on the computer. The problem persists.
