funny, I never had this issue myself.

In case it's useful to anyone, I am using the patch attached on my
laptops; it tells estd to switch from the aggressive to the smooth
frequency-switching strategy whenever the AC adapter is disconnected or
connected, accordingly.

The relevant lines should then be uncommented of course (the ones
invoking "pkill").
