Hi there Jonathan,
Thanks for posting on this forum. We looked into the two guides in question, and it does seem that they are duplicate guides. After doing a little more digging, it looks like you were working on your guide at the same time as a team of students in our [https://edu.ifixit.com/|Technical Writing Program] who were working on a set of guides for the E6530. You mentioned that their guide is missing a step. As a member of the iFixit community, feel free to edit their guide and improve it! In true wiki fashion, the guides on iFixit are a collaboration, so don't hesitate to help improve any content you see on the site.
Let us know if you have any questions or comments. Thanks so much Jonathan and happy fixing!
Justin Ogihara
