I'm not sure where to add a comment about your device page, so I'll just add one here.

Your device page is set up correctly and has good background information about the device. Make sure to add more additional links to help users double check that they are using the correct repair guides for their device.

The link to your troubleshooting page isn't showing up as a link. To figure out how to make a link, look at another repair guide that has working links. Click on "edit," and use their link set up as an example of how to set up your own link.

Very nice guide! The steps are in a logical order and hands are used to show how to replace the battery. When you say in step 2, "remove all four 4mm screws with a screwdriver," include the type of screwdriver they need to use to remove the screws in that step. Your pictures are all focused and in a logical order, but adding markups to the pictures will add more clarity for the user. If you set the white balance of the pictures so that the background looks white, it will allow all of the device parts to stand out more. Also, you don't need to add steps about reassembling the device. The conclusion "to reassemble your device, follow these instructions in reverse order" covers the reassembly of the device.

Very nice troubleshooting page! Your URL is formatted correctly, and all of the issues addressed in the page are common problems. I would add more information into the problem descriptions to make sure the user knows what issues to look for in their device. For example, in the section "unit connected to charger but not charging," add another possible problem the device could have instead of only saying "replace charger." Also, feel free to use articles, (a, an, and the), to add more clarity to the page.
