I'm not running on battery, but I also see those "failed to get cpufreq

Hi,
Just curious, is xen-acpi-processor module loaded in dom0 (lsmod /
modprobe xen-acpi-processor) and what does xenpm get-cpufreq-para
tell you?

Hi there
I've been using Qubes for about 18 months now, and it's great.
My only complaint is the poor battery life I get. I've followed
various recommendations within qubes-users about using powertop
and tlp, but nothing seems to address the rapid decline in power
I experience when running on battery.
Some system information:
Kernel Version Linux version 5.4.88-1.qubes.x86_64
System Name PurismLibrem 15 v44.0 (Pureboot)
CPU Information 2 Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz
OS Information Qubes release 4.0 (R4.0)
Probably the biggest clue I have received was from running tlp
stat, which suggests:
"Reconfigure your Linux kernel with PM_RUNTIME=y to reduce your
laptop's power consumption."
This seems to be reinforced by the following output from powertop:

Looking at
https://github.com/QubesOS/qubes-linux-kernel/blob/master/config-base
<https://github.com/QubesOS/qubes-linux-kernel/blob/master/config-base>,
I can see CONFIG_PM_RUNTIME is absent from the config. I'm
willing to try recompiling the Linux kernel for Qubes with
PM_RUNTIME=y, but my understanding is that I would need to set
up a VM running Fedora 25. Before I head down that rabbit hole,
I wanted to ask if anyone had experienced similar problems and
tried this solution. Further, is there a reason that flag is not
currently included in the base config?
Thanks in advance,
Jonathan
