    Before you say anything ive tried upping the setting in the brightness section. it cuts my ability to brighten it by 50% so say there are 6 brightness settings overall. On battery you can only have it at level 1 2 or 3

    Try this to adjust brightness: on your keyboard, press Fn and arrow key ( up arrow ) at the same time. I have an Inspiron 1525. Maybe it will also work on your laptop since they are both Dell.

    Go into the BIOS setting. When you boot up your computer, press F12 while it is still on the Dell loading screen. There should be an option for adjusting display settings. There is an option to adjust the brightness of the screen while on battery setting. Set this brightness setting to maximum.

    That should allow you to get back to full brightness while on battery. Don't worry, your individual power savings settings in Windows will still work and dim the screen when necessary, but you will be able to go back up to max using the Fn + arrow keys.

    Hopefully this should work.
