Thinkpad T495

[LuMiWa]

Hi!

I have installed FreeBSD-13.0-RELEASE on Thinkpad T495 and I have a
problem with very fast battery draining. I bought used laptop but on
Windows 10 were not battery problem, than I wipe them and installed
FreeBSD-13-RC5 which was good too but now on RELEASE is battery
problem. I have the same settings as I had on RC5.

CPU information

Machine class:	amd64
CPU Model:	AMD Ryzen 5 PRO 3500U w/ Radeon Vega Mobile Gfx

In /boot/loader.conf I have:
security.bsd.allow_destructive_dtrace=0
cuse_load="YES"
amdtemp_load="YES"
# acpi_ibm_load="YES"
cpuctl_load="YES"
loader_logo="beastie"
cc_cubic_load="YES"
# machdep.hyperthreading_allowed="0"

If I load acpi_ibm than I got a message: driver bug: Unable to set
devclass (class: ppc devname: (unknown))

Sometimes when I boot a laptop I got acpi_ec0: no response to 0x 84
acpi_ec0: GPE query filed: AE-NO-HARDWARE RESPONSE

I do not know what information will be helpful.

Thank you.
