I still see the comparison with the network manager - if people switch
places, they most likely switch networks, too.

I still claim that a pop-up is a too agressive solution for this duplicated
and rather informational type of notification. What does a user do when he
wants to check the battery state? He looks at the icon. What would the user
do when he wants to check whether his battery is not used anymore? I believe
he would check the battery icon - the same thing he does when he check the
battery state. But every user doesn't need to be informed about it. There
are some cases when a user wants to be really sure - he can check it like he
checks the energy level of the battery.

Pop-ups should be reserved for events every single user needs to be informed
about. I don't think removing the power cord (most likely he did that
himself, after all) makes the cut.
