how do i get a new battery for my surface tablet laptop

To get a new battery for your Surface tablet laptop or to repair it if it won't hold power after unplugging, you have several options:

1. Customer Self Repair: You can perform a self-repair using parts from Authorized Device Resellers. For instructions, refer to the Customer self-serve repair guide.
2. Microsoft In-Region Repair: You can submit a repair request via the Surface Management Portal or Surface Support Portal. Check for eligible devices and regional availability.
3. Authorized Service Providers: You can send your device to an Authorized Service Provider (ASP) for repairs.
4. Battery Replacement Service: Microsoft offers battery replacement services for various Surface devices, except in some regions like China, India, and MEA. This service is available for a fee for devices such as Surface Laptop 3, Surface Laptop 4, Surface Pro 7, and others. You can check the costs for out-of-warranty service on the Microsoft support site.

Make sure to follow the appropriate steps based on your device's warranty status and your preference for self-repair or professional service.
