I also want to add to the list LG Gram 16" 2021 .
It was driving me crazy!!!
Battery drainage , unwanted CPU usage ( thus system heating up ) and generally not what I used to know what suspend / sleep is, from my older machines. I paid 1370 euros and I thought that my machine was broken before I find out after hours of reading and searching that this is a "modern" sleep!
No go for me at all. I hate it , I do not want it and thank God I found a DELL forum with other people having the same issues .
Also there is a fix in one of their posts that I applied and after some tests, on my one month old laptop , it seems that it works now like it should! This fix is more or less what fluXion posted here!
This should be escalated in tech news...
It should be optional , not shoving us "features" down our throat.
Thank you.
