Hi aford799,
Welcome to the HP Support Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I saw your post regarding your question about the microswitches. HP does not have those available for purchase but if you contact HP there might be some repair options available to you. Contact HP Total Care at 1-800-474-6836 in North America or visit this link outside of North America.
Thank you,
