Dell Desktop Mode Battery Utility for Alienware 13

Hi there, 

I have turned on the desktop mode in the dell battery utility which holds the battery charge at around 50% to 80% level. However, after resetting the system I lost this software and somehow the desktop mode is still on and I have no way to turn it off (so I can't charge my battery to full).

I guess if I could reinstall Desktop Battery Utility this would be solved, but I couldn't find it anyway (not even on the drivers/apps support page). Is there anyone who knows where I can download the software for Alienware 13 or other ways to turn off the desktop mode? 

Cheers
