Computers that the ACPI does not support S3
by mishehu from LinuxQuestions.org on (#5J5E0)
Have any of you encountered any systems out there that don't support S3 mode for sleep? I have an Asus Zenbook UX425IA, and unfortunately even with the most recent UEFI BIOS version (build 309) it still lacks support for S3. It kernel 5.12.x reports "ACPI: (supports S0 S4 S5)" mode. Thus when it goes to sleep, it's not really all the way asleep and is still generating substantial battery drain for something that's supposed to be sleeping, as well as heat. About 2 of 3 times it won't even wake properly from sleep then, and I have to force it to power down. A lot of searches online turned up that it's most likely using S0 mode instead, and that this is a result of some stupid new "enhanced" sleep mode for Windows.
My question is this: if you've got a machine like this, how are you handling getting the machine to sleep? As it's a notebook, I want it to sleep frequently as I'm taking it places, and don't want to have to constantly restart or even have to monkey around with hibernate.
