Hi dhendricks,
Thank you for reaching out Microsoft Community. We apologize for the inconvenience this has caused you.
What I'd like you to do is to reset this device back to its factory settings in order for us to determine whether the clipboard/tablet(part) you recently received as a replacement is defective or whatnot. In the event the issue exists after resetting the device, then the best resolution I can advise is to contact our Microsoft Surface Support again to get another replacement. Anything that involves replacement can't be processed here in MS Community so it's best to contact our technical support to get further assistance.
if this helps, feel free to mark this post as an answer. Otherwise, don't hesitate to respond to this thread if there's anything else that needs to be addressed.
Kind Regards,
Crest_Z
