I can not find the specific motherboard on my laptop.

I can not find the specific motherboard of my laptop, I have already looked at websites, in programs, they give me an information, however, it is not specific, both because when I search I do not think. Also I can not find the model of my laptop, even though I bought it in "Best Buy", I know that it is a Lenovo Y50-70 Touch, but when I write my model, it just does not appear. I need a motherboard because my usbs were damaged even though I took them to technical support and changed them.

I am not 100% sure, but it may help, just ask seller for more details. Or using that part number to find more info.
