Hello, AT_P.
Welcome to Microsoft Community!
According to what is known in the community, the Microsoft Complete Extended Warranty Program covers mechanical failures and accidental damage to the device, including drops, liquid spills, and cracked screens:
Microsoft Complete - Protection Plan for your Surface or Xbox- Microsoft
However, specific to whether or not the charger is covered by the extended warranty, typically the extended warranty program focuses on the device itself and does not cover accessories such as the charger. You can also find out the specific warranty status of your current device through the Surface App:
Surface warranty: FAQ - Microsoft Support
If you need to get further support, I recommend getting in touch with the Surface Support team to inquire about the repair details of your device. Also Surface support can verify with you if your charger is covered under warranty. I share with you the steps to create a service order here:
Open the Surface App (usually built into your Surface device, or you can download it from the Microsoft Store if you don't have one) and follow the procedure below:
- Click "Help and Support" and then click "Get Help".
- Briefly describe your problem in the text box, such as "Surface charger not working", and then press Enter.
- Click "Contact Support" at the bottom.
- Select "Technical Support" and click "Confirm".
- You will see "Chat support" and "Phone support" options, please contact them during working hours, you will get one-to-one support services.
I wish you all the best.
Best Regards.
