Windows 10: System returning from sleep three seconds after entering - why?

In the past month month, my computer, running 2004, has stopped its normal overnight behavior of entering sleep three hours after I restart it, then staying asleep until I wake in the morning, with waking from sleep on its own three seconds after entering sleep.

You can see this below from the event viewer:





The event above it, 107 (102), has the system resuming from sleep three seconds later.

Actually, before the event shown from 10/9, it hadn't entered sleep since 10/6, when it remained in sleep for three seconds.

And a look at the event log - which I swear used to go back more than a year but now only goes back three weeks - shows that if the system ever entered sleep during that time - most days it did - it would wake in three seconds, and then when I touched the computer (clicked or jiggled the mouse) hours later, Event ID 1, power troubleshooter, would say the computer has returned from a low power state.

Is this normal? I am 100% sure the computer would sleep - not sleep and wake, then return from a low-power state - at one time. How do I get the computer to actually sleep again, until I wake it hours later?

Computer wakes up seconds after it enters sleep mode.

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

This may happen due to its power plan. A power plan is a collection of hardware and system settings that manages how computers use and conserve power. For this, we suggest that you reset and restore power plans to its default. kindly follow these steps:
