The screen was dark on my laptop although it was running properly. looked up a troubleshoot and got a part. i intalled this part and my laptop worked like new.
It went fantastic. i looked up how to take apart my computer, replaced the part, and wala my computer was like new.
well.... one word of advise. It definately helps to have about 4 hours for this. it takes a while to take apart the computer and replacing the part is kinda a pain.
