I have bought 2 computeres this year from my LDS. I have registered them online for the warranty but I did not know if the cards had to be sent in or not:huh: . Both times the warranty card was seperate from the box and I had to contact the LDS to send one to me. I am hoping that registering on the website was enough since it is now past the 30 days for both. I have not had any problems with the units and I have nothing but praise for them . Please let me know if I still have warranty on these.
