I don't understand the details of the behaviour it seems an issue with
power-profiles-daemon. And yes if the profile fails to change the
settings should display the error but it's not clear to me if the
service fails or if the action doesn't reflect as you expect. The
mentioned ticket seems to discuss details on how the profile impacts
performance exactly on some lenovo laptops and also suggests there might
be firmware issues on some of those machines

Title:
Power settings have no effect and offer nonexisting options
Status in power-profiles-daemon package in Ubuntu:
New
Bug description:
The "power" area of the settings offer three options:
powersave, balanced, and performance.
As per cpufreq-info "balanced" is not a valid option.
Also changing to any of the two really existing options does not
change cpu frequency in a visible way.
Maybe there is a connection between this and the bug i reported about
the matching indicator:
https://bugs.launchpad.net/ubuntu/+source/indicator-
cpufreq/+bug/1977659
I *can* actually switch between the values using the studio-controls
application. changing values there leads to visible changes in
cpufreq-info output and /proc/cpuinfo data shown.
