This is a common problem with the Gateway 450 Series Laptop.
If you screen is just dark and external monitor works fine. 90% of the time the problem is going to be the Inverter Unit and not the back light bulb.
The inverter unit is what powers the back light, ie turns on the light.
If you need more help or need the inverter unit, give me a call.
I would be more the happy to help.

I have already opened the laptop, but honestly have no idea in what direction I should be looking.
Is this a hopeless case?
Any help would be awesome!!
