Hi, Pietro.. I don't have a direct answer, but one thought occurred to
me. Do you have a way to boot again from either of the other releases
again to see if it goes back to your ~4 hour expectation?

That's all I got, grin. It would have to be almost exactly the same as
before. In other words, it's.... well, on second thought, I don't

Can anyone present a test screnario where the power usage would be at
least somewhat similar without having to undo a new installation? What
I'm imagining is testing via a memory stick'ish or external hard drive
situation. Not scientific, but it might yield something of possible
use, anyway... Or not. :)
