Well, you don't need to remove the power for running "acpi -V", it's just
a requirement for powertop to make an estimation :-)

It can be. I find the "acpi" command not to be 100% reliable. Moreover,
when you run it on desktops in barely outputs useful data:
sm01@stt008:~$ acpi -V
Cooling 0: Processor 0 of 10
Cooling 1: Processor 0 of 10
Cooling 2: Processor 0 of 10
Cooling 3: Processor 0 of 10
Which says nothing.

Looks right. Are you still receiving the error?

Well, let's see. Of course both outputs differ, that's normal because
they're different utilities focused for a different usage. The acpi
command is just an approach to the status of the battery and some acpi
stuff while powertop is a more complete tool that helps you to save
energy and money, it scans your system energy usage and makes nice
reports and recommendations on how to save a bunch of watts :-)

I wouldn't worry about that. Should I have to trust one of them I'd go
for the GNOME applet :-)
