This test case measures energy consumed by you system while in active idle with powersave tuned profile activated.

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.
- Enable tuned laptop-battery-powersave profile by:
# tuned-adm profile laptop-battery-powersave
- 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.
