Ok, now since its just Under 1 year old you are in good shape as far as a free repair from Samsung ;-)
What you have is a broken slot catch and that is under warranty as is your computer 100% covered still at this time.
What you need to do, is contact Samsung, using the phone contact information on the warranty card, and in the user manual that came with your computer. They will set up shipping and tell you where to either send or bring it in for this repair. Also there will be no cost to you for that.
If you cant locate the phone # I will send you one, but the one that came with your computer will work quicker with any run around with phone transfers lol
In any case, I will stick with you until this is complete.
