Hi Gardner Thornton,
I understand why this is frustrating. Since the Surface Pro 11 will not power on, running or downloading the Surface Diagnostic Toolkit on that device is not possible.
If the online repair process continues to redirect you to the toolkit, please contact Microsoft Surface Support from another device. Clearly state that the Surface has no power, you have already completed the available troubleshooting, and the automated workflow will not let you proceed. Ask the support representative to help create a mail-in service order manually.
Please have the Surface serial number and proof of purchase available, as Microsoft may need them to verify the device and its warranty. If you cannot sign in with the affected account, you can use another Microsoft account to reach support and explain which Surface needs service.
Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. My role is limited to providing technical guidance on reported issues, requests, or ideas. Thank you so much for your understanding.
