I have the same problem on a Dell Inspiron 6400 notebook (15,4", ATI x1300), but it behaves differently depending on use of AC power or battery:
1. On AC power: it turns 100% bright randomly. Manually setting it darker works for a few minutes, then it increases to 100% again. 2. On battery: The default if darker. Even adjusting to be very bright, it turns back to the previous value. -- Screen brightness switches from bright to moderate randomly.
