I looked into some more things to get this solved.
While the Setting application says my power mode - the one it keeps
getting back too despizte I chose another is "balanced", looking into
the system it tells mie it's on powersafe:
$ cat /sys/devices/system/cpu/*/cpufreq/scaling_governor
powersave
...
(repeated with one line like this for each cpu core i have)
Looking at cpufreq-info, it tells me there is not "balanced" option:
$ /usr/bin/cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpuf...@vger.kernel.org, please.
analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 4294.55 ms.
hardware limits: 800 MHz - 4.80 GHz
available cpufreq governors: performance, powersave
current policy: frequency should be within 800 MHz and 4.80 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency is 4.43 GHz.
So I wonder what the balanced option is about, if it's not reflected on the
system, but despite that the system keeps going back to it.
I read the ubuntu help pages about the power mode, and it says these
options in the setting application should do what they look like.
But I cant confirm this.
It ignores my choices, and reverts back to a setting that doesn't event seem to
be known to the system.
