If the Surface shows 0%, only runs while plugged in, and turns off when unplugged, a service request can be started from the Microsoft devices page.
Steps:
- Go to account.microsoft.com/devices and sign in.
- If the Surface Pro 8 is not already registered, register it to the account first.
- Select the Surface Pro 8.
- Select Start order.
- Follow the prompts to create the service request.
If the battery icon shows a red X and the device turns off when unplugged, Microsoft directs starting a service request from Device service and repairs.
Battery replacement options may include:
- Authorized Service Provider support for in-person service, depending on country or region.
- Battery replacement service through Microsoft, depending on device, warranty status, location, and coverage.
- Self-repair with available replacement components and service guides, intended for technically skilled repair.
If the device is visibly swollen or the battery has expanded beyond the enclosure, stop using it and handle it carefully to avoid pressure or puncturing the battery.
