Check Surface warranty

Submit a Surface warranty service request

Prepare your device serial number and proof of purchase. The Microsoft service portal may require a work or school account, verification and the appropriate organization access. Follow the portal instructions to submit your request.

Choose your product and check its entitlement

Coverage depends on serial number, sales region, proof of purchase and the applicable service contract. These links lead to China-region vendor support. Yihe assists with coordination; this page does not identify Yihe as a vendor repair centre.

Four steps before repair

  1. Prepare model, serial number, proof of purchase and service-plan details.
  2. Record symptoms, timing, errors and troubleshooting already attempted.
  3. Back up business data and follow vendor instructions for recovery keys and device preparation. Do not submit passwords or recovery keys through the website enquiry form.
  4. Obtain an official case number and confirm charges, shipping, accessories and handling arrangements.

Understand the different types of coverage

Limited warranty, accidental damage protection and extended service have different terms. Batteries, accessories and data services may follow separate rules. Brand name alone does not establish a service period, free on-site visit or replacement entitlement.

How Yihe can help

We can help organize purchase information, identify official repair channels and coordinate case follow-up. Vendor diagnosis, entitlement, charges, repair method and timing are confirmed by the vendor or its authorized service provider. Loan devices and on-site assistance require a separate agreement.
