I have searched everywhere, emailed a few parts companies online, called alienware, and I still can't find this part. Its the small board that the DC power input attaches too on an alienware M5700 area-51 laptop, it also has a USB plug on it. I did talk to one guy who wanted the number off of it but unfortunatly the edge of the board that has the jagged edge is going right through the Part number which you can kind of see from the picture. All i can get off the number is P/N : 35 - EP. Oh and as you can see a friend tried to fix it by soldering on a new dc input, which may be why the board is now ruined.
