Your right. The thing is I'm working on someone else laptop. They want to know how much it would be to replace the mother board. I need to give them a price so they will know what the MOBO cost is. Once I tell them, they will know its best to replace the laptop. I was wanting to find a reputable source for MOBOs for the future as well. When I searched online I found the MOBO but the prices varied dramatically, which is why I needed a legit source. I have never had to look for or purchased a MOBO.
