Title:
  Laptop becomes very slow on Battery

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hello,

  I have a problem which I don't find a solution for it. And it only
  happens when the charger is disconnected. The problem is the fallowing
  :

  - When the charger is connected the OS is fast. 
  - But, when it isn't, then Ubuntu becomes impossible to use because of it slowness (taking up to 3 minutos to open an application if the mouse is not on top of another application).

  A workaround that I've found is to disable pm-powersave by doing :
  "sudo pm-powersave false". But this workaround causes 2 problems :

  1 - It need to be loaded every time I boot the laptop
  2 - If pm-powersave is set to false then the laptop won't Suspend.

  Another thing : My laptop has an nVidia GPU and I am using the Nouveau
  driver. If I boot the computer with the "nomodeset" option set in the
  kernel, then I will have a small resolution, no visual effects, but
  there will be no slow down problem

  Best Regards,
  Luis Da Costa
