my surface Pro is restarting on its own

Run the Surface app’s update check and diagnostic tool first; this tests Surface-specific firmware, battery, charging, and hardware without assuming whether the random restarts are caused by software or hardware.

1. Update and diagnose the Surface

1. Save your work and back up important files because another restart could interrupt an update or cause data loss.
2. Open Start, search for Surface, and open the Surface app.
3. Expand Help & support.
4. Select Check for updates, install everything offered through Windows Update, and restart normally.
5. Return to the Surface app and select Get help to report the random restarts.
6. Open Surface Repair Tool from Start. If it is unavailable or says the model is unsupported, open Surface Diagnostic Toolkit instead and follow the prompts. The tools are designed to identify and repair common Surface problems.^1^

Note whether the battery/charging or Modern Standby tests fail. The Surface Diagnostic Toolkit can save its results, which will be useful when updating your existing support case.^2^

2. Isolate connected hardware

Shut down the Surface and temporarily disconnect:

• Surface Dock
• USB devices and hubs
• SD card
• External monitor
• Type Cover and other accessories

Then use the Surface on its original Microsoft power supply. If the restarts stop, reconnect one accessory at a time until the problem returns. Microsoft identifies connected accessories as a possible source of Surface startup and power problems.^3^

3. Record what appears during the restart

If a blue or black error screen appears, photograph the stop code and any driver/module name. Windows unexpected restarts can result from hardware, drivers, or software; the displayed stop code helps distinguish them.^4^

Also note:

• Whether it occurs on battery, while charging, or both
• Whether the Surface feels unusually hot
• Whether it occurs while sleeping, under load, or when idle
• The exact date and time of each restart

If the same stop code repeats, Microsoft’s next checks include removing recently added hardware, checking Device Manager for warning icons, maintaining roughly 10–15% free storage, and installing all Windows updates.^4^

4. Continue the existing support case if it still restarts

Contact Microsoft through Surface app → Help & support → Get help and provide:

• Your existing case number
• Surface model and Windows version
• Saved diagnostic results
• Stop-code photo, if any
• Restart dates and times
• Whether the issue occurs on battery and AC power
• Whether disconnecting accessories changed the behavior

If updates and diagnostics do not resolve the issue, Microsoft documents reset/recovery as the remaining software step; if the issue continues after a reset, a service order is required.^1^ Back up your files before any reset because recovery options can remove apps, settings, or data.
