need a replacement for the pq302 part

Hi.

I have a lenovo y50 touch (i7 4700, 2x8gb, touch model).

One day it stopped working. I checked and the part labeled as PQ302 was visibly damaged (busted).

Unfortunately, since the top is damaged, I can't see the name of that piece, I need to know the name of that so I can search for an equivalent and replace it.

Thanks for your help.
