we need a picture of the actual item with your user id on paper next to it so we cvan verify its yours and getting some verification would help like phone credit card or bank
The P/N # on the case is NN109AA & the S/N:CNH0481126 is on the speaker. I purchased these when the sound went out on my previous computer. I don't use or believe in credit cards and no one but me needs to know my bank info.
