Personally I've disabled pstate driver from kernel command line. Events like suspend, lid close and restart completely changes the behavior.
While working on battery I sometimes will close the lid and when I open back CPU is at 4Ghz and battery gets drained in 30mins. Not to mention the heating. *It simply doesn't work.* The acpi driver is much better and battery life is great too. No lid/suspend issue so far. I'm on Ubuntu 20.04 stock kernel: Linux Predator-300 5.4.0-40-lowlatency #44-Ubuntu SMP PREEMPT Tue Jun 23 01:32:24 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838141 Title: intel_pstate not working.
