Thank you for posting your question in the Microsoft Q&A forum.
Regarding your issue, unfortunately, Microsoft-authorized service centers in India do not currently offer battery replacement for this model. The official support option in your region is a full device replacement through Microsoft Support.
You can review the official policy here: Surface service and repair options.
To start the replacement process, please follow these steps:
- Go to How to get service or repair for Surface
- Sign in with the Microsoft account linked to your Surface device.
- Check your warranty status.
- Create a service order for device replacement.
