Hmm, this could be a problem with the backlight inverter or something as simple as power settings.
In power settings from control panel there should be an option to alter the brightness lever of the screen when on battery.
Have a look in there and set it to default to see if it makes any difference.
Let me know if you need any more help.

What you have is an inverter failure most likely. The inverter takes the AC adapter voltage and converts it to high voltage AC for the backlight bulb. Backlight bulbs rarely fail but the inverters do. Ebay has inverters for around 15-20 bucks. The inverter sits under the lcd panel behind the screen bezel. In most cases, removing the bezel is all you need to do to change the inverter out. Below is a link to the service manual for that model.
When you click on the link go to page 4-61, this is the start of the lcd disassembly. I thing just 4 screws need to be removed and then take your finger nails and pry off the bezel in a small area and work your way around the screen until the bezel comes loose. When replacing the bezel always start at the bottom between the hinges and work your way up and around.
