Is your PC not being recognized as a laptop? – david6 May 20 '12 at 11:28
Do you have a battery indicator icon (top right of screen)? See: – david6 May 20 '12 at 11:34
I would suggest an upgrade to Ubuntu 12.04 LTS – Ross Fleming May 20 '12 at 13:40

Click on the Dash Home button and type screen. and click on the Screen Control Panel that comes up. There you can tell Ubuntu not to dim and and then turn off the monitor (but not brightness, you may be able to do that by pressing marked keys on your laptop). I'm not aware of software to do that on 11.10.

If you take Ross Fleming's advice and update to 12.04 you can use the Brightness and Lock control panel to control screen brightness and when the monitor is turned off.
