Hi Linus,

Thanks for the info.

If it's as bad as you suspect (i.e. replacing the CPU) that sounds like a
pretty expensive repair; maybe nearly as much as a new unit! That's a
major drag. :(

As you may recall, I am actually a (very part time) developer myself.
What would be involved with writing the manual procedure that you
suggested? Is it just a matter of creating a menu item and tweaking a bit
somewhere to activate charging or is there something more complex
involved?

If you want to post your reply to the developers list to discuss the
coding please do; I'm on both lists.

Thanks again,
