Hi ChrisWAinsworth,
Thank you for reaching Microsoft Community. I understand that you're having trouble charging your Surface Pro 7 through the USB-C port.
First, may I know what are you trying to use in charging the device through USB-C? Is it a power bank? How much power output does it have?
Please note that in charging Surface devices through the USB port, we recommend using a USB-C PD charger that provides at least the same wattage as the power supply that was designed for your Surface. The Surface Go comes with the 24W power supply while the Surface Pro 7 comes with the 65W power supply. With that, the charger that you are using may not be providing enough power to charge the Surface Pro 7 through the USB-C port. Please see this page for more details in charging Surface through USB-C: USB-C and Fast Charging for Surface - Microsoft Support
If you've confirmed that the power delivery of the charger that you are using meets the requirement which is 60W or higher and still the issue persists, please try using a different USB-C cable to see if the issue persists. It's possible that the cable you're using is faulty or not compatible with your Surface Pro 7.
If using a different cable doesn't work, there are a few other things we can try. Here are some possible causes and solutions:
- Check the USB-C port: Inspect the USB-C port on your Surface Pro 7 for any damage or debris. If there is any debris, gently clean the port with a soft, dry brush. If there is damage to the port, you may need to contact Microsoft support for repair options.
- Update your Surface Pro 7: Make sure that your Surface Pro 7 is up to date with the latest software updates. To check for updates, go to Settings > Update & Security > Windows Update.
- Check the drivers; and run diagnostics: Check for the Surface drivers' health through the Surface app and run the Surface Diagnostic Toolkit to run some system checks and repairs. See: Fix common Surface problems using the Surface app and Surface Diagnostic Toolkit - Microsoft Support
Let me know how it goes.
Kind regards,
Marrion
