Thank you for the extensive explanation!
Ok, at the end of each day I will give a look to "dmesg", just to be
sure that everything went fine.
I will also check for firmware updates before starting the tests.
A few questions/statements:
1) is it okay to run the tests with the power cord plugged? Or do I need
to use battery in order to trigger such kind of power saving features?
Running the tests with the power cord plugged in is fine, but to get
info on how much power this actually saves you need to be running on
battery since most laptops can only measure power-consumption while
running on battery. After getting the initial idle and idle power
consumption with the new med_power_with_dipm policy activated you
can run with the cord plugged in.
2) In your guide you specified "[...] on a clean Fedora". I
actually
cannot run a new Fedora installation on my SSDs, but I haven't messed up
with any kind of strange powersaving features, so it should be fine to
use my regular Fedora installation for the tests. Do you confirm?
Yes that is fine.
To be
sure, I will attach to test results e-mail, also:
- /etc/fstab
- /proc/cmdline
- # lshw
3) Since in these days I am not using much the Thinkpads, I think I will
run Phoronix suite in order to simulate machine activity
Among all Phoronix test suite tests, If you think that there are some
that best fit your case, please let me know. To read a list of disk
oriented benchmarks, you can do:
# dnf install phoronix-test-suite
$ phoronix-test-suite list-available-tests | grep Disk
Sounds good.

Hans
