What model of ThinkPad do you have ?
I have a T14 G3.
It's a fairly recent model (February 2022), I can't say if it's not
supported by thinkpad_acpi yet, but trying good old acpi_call may be
worth it. Bear in mind that I'm only the package maintainer, not the
main developer, so I'm really not sure if it's the cause of the problem.
Maybe the natacpi driver doesn't work and you need another one.
I don't know how to switch to another driver. Would you be able to point
me to documentation on how to do that?
Make sure you install the kernel headers package matching your kernel
(probably linux-headers-amd64), and then install acpi-call-dkms. It
should build the module automatically. Then try to load it :
$ sudo modprobe acpi_call
...and tell TLP to use it by disabling natacpi (which supersedes
tpacpi-bat). To do so, change the value of the NATACPI_ENABLE to 0 in
tlp.conf. Restart tlp, and see if it solves your problem.
If loading the module says something like "Operation not permitted", it
means secure boot is enabled and you have to create a key pair, enroll
it in the MOK (machine owner keys), and sign the module with it. It's
far outside of the scope of TLP, so in the meantime, for the purpose of
testing, just reboot into BIOS and disable secure boot.
