Good luck if you can, on some new motherboards you cannot disable S0x in the BIOS and cannot enable S3 as it does not exist anymore.
You can only use this "S0 idle" which is like your cellphone sleeping, meaning everything runs and/or is somewhat disabled in background. Instead of the BIOS disabling things, it's the OS and the applications and drivers that have to take steps to go sleeping but it's way from perfect and takes power anyway.
Problem is with laptop. A laptop in S3 (suspend to RAM) can last a few days, a laptop in S0 idle will last a few hours.
So if I have my laptop in bed at night and then close the laptop lid to go to sleep and wake up, the reason the battery is fucking dead is because the laptop never actually "sleeps" - it just enters a lower power state while still draining battery relatively aggressively?
If it does not support anymore S3 mode, yes 😕
The insane thing is that it was working a few weeks ago but then it randomly went away. Like the computer would go to sleep like normal (S3) and then I'd wake up to at least 80 percent battery. Now? All I have is hibernate. Man, as bad as Windows is and always has been, I can't believe it's somehow getting worse with time.
Some BIOS updates remove the S3 option so that's possible. It's also possible that Modern Standby was working before and something changed which broke sleep for you. You can run a Sleep Study (instructions on the web) to see how your computer has been sleeping but it sucks that you'd have to resort to that.
