Hi, my girlfriend had dropped her laptop (toshiba satellite m70) a week ago and i bought a new inverter for it as the screen backlight would not work... i just installed the new inverter and now the backlight works, and it seems to be fairly bright when the lcd display was still taken apart.. i put everything back together, and the screen and light work, but its still really dim (its still usuable but very dark.... i am using the laptop right now) i have tried making the screen brighter by hitting fn+f7 ... and its already at full brightness,... is there any other setting i could change to make the screen brighter?? the bottom 2 inches of the screen are much brighter then the rest of the screen as well... what would be causing this??

NO.
The most likely cause of that is the backlight is in the process of burning out. It's a CCFL - Cold Cathode Florescent Lamp - like all florescent lamps, it slowly gets dimmer as time goes by, and eventually it burns out.

"the bottom 2 inches of the screen are much brighter then the rest of the screen as well... what would be causing this??"

That's simple....
"Hi, my girlfriend had dropped her laptop"

That did more damage than you thought.

If it were merely the backlight is in the process of burning out, the display would be equally dim all over. The display assembly is damaged. You need to replace the display assembly with a new or used one. A used one will not have a new backlight in it. A re-furbished display assembly is cheaper than a new one, but is a good deal ONLY if the backlight has been replaced, otherwise it's just a used display with another label.
......

If you want to check whether the display adapter is damaged, if the laptop has an external VGA port, connect a monitor to it, but there's probably nothing wrong with that and the display on the monitor will look fine.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / sometimes both / built in display video only - see the Owner's or User's manual for the model.
