Yes, I saw both of those. But I offered the gui version in case that
helped.
Configuring through the GUI worked. I didn't consider it as a "Power"
option when I first looked because it's not a laptop, but should have.
Thanks for your help - I'd be interested in knowing how the eventual
command the GUI uses and how it differs from what we tried previously.
