Description
This test case measures energy consumed by you system while in active idle with deactivated tuned (e.g. the default setting).
This test targets laptop users or users with wattmeter.
This test will take approx. 15 minutes.
If you do not have laptop (or PC with wattmeter) or if you do not have enough time feel free to skip this test. In this case please leave the corresponding column in the results table blank.
If you complete this test, please also complete the Tuned powersave idle test.
Setup
- Check that you have pm-test-day package installed:
$ rpm -q pm-test-day
For better results disable screensaver, screen dimming/turning off, transition to sleep mode and cron service:
- Disable screensaver (if applicable).
- Disable sleep mode, in Gnome 3:
$ gnome-control-center power
- In "On battery power", "Suspend when inactive for:" select "Don't suspend".
- Disable LCD power savings, in Gnome 3:
$ gnome-control-center screen
- Uncheck "Dim screen to save power".
- Set "Turn off after" to max. value.
- Disable cron:
# systemctl stop crond.service
- Disable user PM via gconf (and save previous settings), it needs to be run under user who is logged into desktop:
$ pmtd-pm-user-settings saveoff
- After the test it is possible to restore the previous settings by using the restore parameter instead of saveoff.
How to test
This test needs to be run on battery (laptops) or with connected external wattmeter. In case you have laptop and also use external wattmeter please disconnect battery.
If you are running on battery, please recharge your battery to full capacity before running this test .
If it complains that the test cannot be run on your computer, use external wattmeter or skip this test.
If the screen blanks during the measurement, unblank it by e.g. mouse movement.
- Disable tuned by:
# systemctl stop tuned.service
- Run the following command:
# pmtd-measure-idle
- Do not touch your computer until the test completes (cca. 15 minutes).
- Write the output to the results table.
Expected Results
- Energy consumed during the test is written to the stdout.
Results can be in mAh or mWh.
