Note that I log a= ll events and have an extra output for the THM event so the output is a bit noisier that necessary.

There doesn't seem to be any apparent pattern that would provoke this. All I can tell is that the power profile seems to switch itself back from "performance" to "low-power" after some time. It can take anywhere from 5 t= o 70 seconds for this to happen. It also looks like the "balanced" profile seems to stick but I need to veri= fy this better. --=20 You may reply to this email to add a comment.
