Also, the rubric asks for at least 5 troubleshooting topics, but the device is pretty simple, so maybe there aren't really any more issues.

This guide is listed as "difficult" yet only requires the use of a screwdriver and some prying tools. It would seem more appropriate to list it as "moderate" at most. I believe the motherboard guide has the same issue.

Also, you say PH#00 in the description of steps, but in the "tools" listing at the beginning of the guide, you said that a PH#0 was needed. These are not the same.

Under the "odd sounds" heading you say "This could be due to the CD drive, if a CD is scratched..." You should list more specific details about the 'symptoms' rather than describe what could be causing the problem. That's what the sub-headings are for.

The screws in red do not seem to need to be removed unless you are trying to replace the eject lever. If you're not trying to replace the lever, it adds an unnecessary complication to putting it back together.
