Toshiba Laptop Wont Change in Brightness even it goes up and down.

[ToshibaJC]

TOSHIBA Notebook A135.

When i press Fn +F7 or Fn+ F6 it wont change at all. The little icon will move though but the brightness wont do anything. I go to power options and move the box all the way to the brightest and nothing happens. It stays at a low level of brightness. AC connection wont affect it either.

Please help.
