I'm writing a tool to collect information about power consumption of notebooks. I need to measure the current power consumption, and I use Perfmon to do so. But I found a strange bug. Here is the typical graph of power consumption (this is "Power Meter" - "Power" - "_Total"):
Measurements are updated about once every 10-15 seconds.
But if the run Everest (or AIDA64) Power Management tab will be updating this more often, the results are more accurate:
Measurements are updated about once every 1-2 seconds.
I do not understand what happens when we run Everest. I really need to get accurate data. Do you have any ideas?
I would really appreciate any suggestions in this regard.
