Linux laptop that sleeps (S2 vs. S0ix) (self.linux)

This is my one deal killer for Linux on the Desktop. I have a stack of laptops with Linux installed (mostly Fedora). They are all Dell Latitudes. My main two are a Gen 12 i7 and a Gen 8 i5. I'd rather use the Gen 12 i7 (it also has more RAM and storage). However, the i7 doesn't have S2 sleep, only S0ix. When I shut the lid, it will lose about 40%-50% battery over an 8 hour period. The Gen 8 i5 does have S2 and sleeps okay with it. I only get a 10% drop in battery over the same period.

I hear that this is some Microsoft-Dell shenanigans to "better" support Win10/11. But is there a lightweight 14" or 15" laptop out there that will run Linux well and sleep without draining the battery so much? Would and AMD system work better than Intel?

I see all the complaints about sleep but there has to be something better than 40%-50% drop on the nightly that would require me to keep it on power just to have a fresh laptop when I need it.

My x1 carbon on mint seems to go for weeks while suspended.

My X1 Carbon does now. But it used to drain to empty after a day or two even if it was turned all the way off. Drove me crazy.

The problem ended up being the always-on USB setting in the BIOS. For some reason, even with nothing connected, that would drain the battery until it was completely flat. Once I turned that off, it'll sleep for weeks like you said.

OP, maybe check the BIOS settings for "Always on USB" or similar and disable that?
