This computer is still under warranty, so go to www.dell.com and create an account, register the computer using Service Tag (you may probably have to use the Express Service Code too). Once registered wait 7-10 days, login into your www.dell.com account and ask for support using their chat, let know Dell representative that you need a master password, they will ask if the password is for the computer you have registered, will ask you to wait and will give you the master password.
Since computer is still under warranty, the master password is free.

Since around 1 month ago, there's the possibility to reset Dell System Passwords in laptops with xxxxxxx-8FC8 suffix using a Master Password, the solution has been proved already many times since March-8th.
So there are 2 possibilities depending on your expertise:
(1) the easiest way is to unlock using a master password or
(2) with some experience using a bios chip programmer to read bios chip and getting it patched.

Advantages for patching the BIOS are: Cheaper and Computrace is removed.
