Hello, Karen Wilson3.
Welcome to Microsoft Community!
If you receive a letter stating that the device is no longer covered under the Standard Warranty, it may be due to changes made to the hardware during your use. We can't go into details beyond what is expected at this time, but I can share details about the warranty program with you:
Warranty and Protection Plan Terms & Conditions - United States - Microsoft Support
Similarly, for repair services, I recommend that you contact the Surface Technical Support team directly for more details on warranty services. I can share with you the steps to create a service order to help you reach them:
- Use your personal Microsoft account (not your organization account) to access the following links:
- Type Surface won't start, press Enter, and click "Contact Support" at the bottom:
- Select Technical Support and select the device model (Surface Laptop) you are currently using in Product family, then click Confirm:
- You will see contact options for Chat support and Phone support, please contact them during business hours:
I wish you all the best.
Best Regards.
