Hello Steve,
Welcome to Microsoft Community.
If you know for sure that you will hear any abnormal noise in the device after the Surface Pro 8 has started normally, turn the device off and do not continue to use it, it could be that the Surface Pro 8 has debris inside, or mechanical failure.
I recommend that you immediately send your device to the Surface technical support team for inspection and repair of your Surface, as well as a battery replacement (remember to mention this when submitting your repair order).
I can direct you to Surface live support who can assist you in creating a repair order, as follows:
- Use your personal Microsoft account (not your organization account) to access the following links:
- Type Surface, press Enter, and click "Contact Support" at the bottom:
- Select Technical Support and select the device model you are currently using in Produce family, then click Confirm:
- You will see contact options for Chat support and Phone support, please contact them during business hours:
I wish you all the best.
Best Regards,
Mitchell | Microsoft Community Support Specialist
