[SOLVED] Why is the lower half of my screen dim, while the top half remains bright?

Ok thankyou clutchc. So do you think it's better to just buy a new one?
As much stuff as I've done with PCs, one thing I haven't done is mess with laptops. I really don't know if the screen can be disassembled to get at the backlighting safely or not. Might want to take it to a PC repair shop for some advice.
Otherwise, it is live with the distraction or buy a new laptop.
