Within Best Buy's Return Window (Standard 15 Days): You can get a full refund or a direct exchange for a new retail unit. Bring your receipt, original packaging, and all accessories back to the store.
Mention Geek Squad already diagnosed the screen failure — this speeds things up and supports a straight exchange or refund rather than a repair-first path.
Under Manufacturer Warranty Only (No GSP, Past Return Window): Best Buy cannot directly exchange or return it in-store. You must file a claim directly through the Microsoft Support Device Service for a warranty replacement.
