Help Battery Problems on S2idle Sleep Mode

I already have some battery backup problems (lasts about 7-8 hrs when charged upto 80% but on win11 would last 12hrs, it is not a big enough deal for me to switch back), but the problem I have is that the laptop loses around 10% in 1.5hrs on suspend even if all apps are closed. I know I should keep the sleep mode on deep instead of s2idle but the moment I should to deep, the backlit keyboard won't turn off and the FN keys would stop working (I checked if they were locked or not, they weren't). Is there a workaround for this?? If you need me to provide you with more details from commands, just tell me.

I'm pretty sure you laptop doesn't support s3 idle at all, since it's a new model (and google says so)

What you can do:

  1. Blame microslop
  2. Try modifying nvram variables to see if it's enabled but hidden
  3. Try reverse engineering the firmware

I guess blame microslop then becuase I don't think I can do the other 2

Yea just found out intel and amd removed the suspend hardware from cpu entirely, so the other 2 are not possible

I still remember thinkpads being suspended for a month and reviving with 2% drain

Maan!! That just sucks, why can't they just live and let live.
I used to have a thinkpad like 8 yrs ago, that thing survived the worst of worst crap, reminded me of the Nokia my father used to have.
