     * One can monitor discharge rate of the battery of a system if no AC power is attached (upower -d).     * One can monitor discharge rate of the battery of a system if no AC power is attached (upower -d).
     * One could use an external power meter. The one I have can not be read digitally, so one has to run the system for some time and then read the consumption from the power meter display.     * One could use an external power meter.

-    * One could consider the whole computer as a system, and that the used electrical power is converted into thermal power. So if one has a sensor reading from the air coming into the system, and the air going out, one might be able to guess. Fan speed influences this. One could also consider the ThermalDesignPower of the CPU to verify if the computed consumption makes sense. Training sessions with/​without AC power connected?+    * One could consider the whole computer as a system, and that the used electrical power is converted into thermal power.
