Great tip. Powertop showed a number (eight, to be precise) of recommendations. For a while, I ran through a reboot, apply one or more changes, wait, repeat cycle with no luck. No, I didn't repeat that cycle 255 times. :-) But powertop --auto-tune worked wonders, and very quickly. This morning, there was another kernel update, to 6.10.2-arch1-1, and now my laptop is back to its older, cooler ways. Powertop shows that all tunable settings are "Good" (although there are still a bunch of Untunable Software Issues). Problem resolved, but not really solved. Thanks David, Ralf, and Ralph for your insights and your assistance. Regards, Dan
