Awesome, thanks. My BIOS upgrades are such a mess. I get notified that I have them.... but they always fail. I haven't dug into the logs to see why. This is honestly the most lazy I've ever been with a Linux install in 20 years, mostly because everything is working "well enough" that I haven't spent time tweaking it. Better battery life/cooler bottom does sound like something I should strive for though.
- Force deep sleep mode, as s2idle doesn't work.
- Set the ASPM policy. To anything. Basically the default doesn't work. (I went with 'powersave', obviously.)
- Run powertop --auto-tune on boot.
- Set the cool-bottom thermal profile, but that's just to make it work as a lap top.
- Run a BIOS upgrade. :V
(fwupdmgr did the whole job for me~)
