CPU interrupts. There are timer interrupts that can be used for this. In hibernate, only a tiny fraction of the CPU is changing the transistor states. A transistor only uses power when it changes state; i.e. “off” or Hibernate. Transistor state changes when you cycle the clock on a CPU. Anyways, set the register for the timer interrupt and signal the CPU for Hibernate. The timer circuit is still listening to the clock while the rest of the CPU stops listening to the clock. Each clock cycle you subtract one from the register. When the register reaches zero, the timer interrupt wakes the rest of the CPU. Just like moving your mouse or pressing the power button; they signal an interrupt which wakes the CPU.
Yeah, update arriving part is not necessary but it wakes the PC up, checks for updates and install them if there are any, does this every night. And if you disabled auto-sleep it just stays like that until you interfere.
Windows wakes up from hibernate? How tf is that happening? Also how tf it knows when to update when its hibernated/sleeping?
Better always keep a gun next to your bed if you use Windows.
Good thing i don’t

There is a thing called wake timers on Windows. There is also Wake-on-LAN but not sure if that’s enabled on default or not.
So they don’t wake when new update arrives but only for prescheduled previously downloaded update?

Shit its wake to check for updates🤦♂ So it happens even if there is no update… Thats so fucked up
from what i understood it wakes up randomly to check for updates, then goes back to sleep. or maybe it just stays on? im not sure
