@tferrusca , welcome to the Community.
Here are all of the components in your AIO on HP PartSurfer: https://partsurfer.hp.com/Search.aspx?searchText=X6G29AA
The first item is AC Adapter. Please read the IMPORTANT NOTICE to assure that you are using the correct Part #. HP provides two of the items, but not all of them. If it is not provided by HP you will have to search for it online.
Please click the Thumbs up + button if I have helped you and click Accept as Solution if your problem is solved.
