Is there an application that would apply power-saving options when switching to battery mode?

Hi All,

I have been toying around with powertop, and there were quite a few 
suggestions that it made regarding power saving. Now, I was wondering if 
we have a Utility / process in F7 that would trigger these changes 
everytime the laptop switched to battery modes... just like the user 
sessions option, with the difference that these sessions apply to 
battery mode as compared to ac-power mode.

Another question that I had was, is the hci_usb module (loaded as part 
of the bluetooth services) meant for USB bluetooth dongles? If that is 
the case, is there someway that I can turn it off altogether? The reason 
I ask is because, everytime I try to unload the module, i get a FATAL: 
module still in use. Now I have turned off bluetooth services, and yet I 
see this issue. Any hints on how this can be accomplished?

thanks,
Rogue
