Hi LilyAnthony03,
Thank you for reaching out to Microsoft Community. I'm sorry for what happened to your Surface Laptop 3.
Yes, physical damage is not covered under normal Manufacturer's Warranty but you mentioned you paid for the extra warranty at the retailer, may we ask what extra warranty is this? Is this the Microsoft Complete Warranty Plan (Accidental Damage)?
If yes, then you can have the device replaced through the warranty claim by paying only the deductible amount (49.00USD in USA).
If it is not the Microsoft Complete Warranty Plan, it might be a 3rd party warranty sold by your retailer and for that I suggest that you contact the retailer for that warranty.
If this answer your question, we highly encourage you to inform our Community by clicking on Yes or marking my post as an answer. This will help other members who may have the same issue as you. Otherwise, don't hesitate to update us so we can further assist you.
Kind Regards,
Marrion Y.
