Joe is using an old Windows 7 laptop but his trackpad is having issues. Leo says that trackpads do wear out over time and that laptop is nearly ten years old. But iFixit.com may be a good source on how to replace the trackpad. It's not that big of a deal. Joe should also check HP forums. If HP has stopped supporting his device, the forums may be a great place to get help from other users who have been going through similar problems.
