Sleep mode has issues. It can wake up and do updates whenever.

If you really want it off, turn it off.

Of course sleep mode might still be worth it. But it's not real sleep like it used to be. It kinda annoys me how often my computer will wake up randomly. And with ssd it's not as big of a deal for desktop.

My greatest annoyance isnt that it can wake whenever, but it  doesn't turn on the fans when awoken this way. So the goddamn laptop overheats and does a restart. I just want old sleep mode back, hibernate is unstable so I've stopped trying to use that instead :(
