I have a Windows dual boot, and Windows did install some updates, and Lenovo site indicates that the latest BIOS version was released mid November, so that could be it.
running sleepgraph crashes the computer same way deep sleep does 😖
Yeah, if the bracket is on deep, it crashes and enter the BIOS recovery thingy. If it’s s2idle, it does what it says on the tin.
No, hibernation saves state to disk, and turns the computer off, drawing no power. Deep sleep is what was for me just sleep until recently: it uses power to keep data in ram, so it’s faster to wake up than hibernation. The amount of power used is really small, so unless you don’t use your lap top for a couple of days, it won’t deplete the battery. New hardware has this new “S2 Idle” state, that is basically an “On” state minus the screen and it’s OS’s job to try to use as little power as possible usually by telling each and every device to chill as much as possible (this is my understanding, but don’t quote me on this). On Windows, with the first party device drivers, this sorta works OK + OS drops to deep sleep or hibernation depending on battery or something.
It’s 2021 Lenovo ThinkBoot 15 G2 Intl with Intel i3-1115G4, 8GB onboard ram, integrated GPU and two NVME slots.

So… Bios update broke deep sleep, because fuck you, that’s why?
Vucic literally spent a year illegally registering people from outside of Belgrade (including Serbs from Bosnia and Croatia) to Belgrade addresses and bussed them on the election day to vote, just so he could narrowly win local elections. That is the main outrage. These protests aren’t even organized by opposition parties, people are just that pissed.
Gasp Don’t remind me how old I’m getting. Joel’s blog was really big deal, upto ~15 years ago when he stopped blogging. He and Jeff Atwood created Stack Overflow.
I mean, yeah, but that’s on the level of “because they’re eucaryote” like us and all plants and animals, as opposed to bacteria which are procaryote. It’s not really some freakish similarities.
