Query: "In Depth" is still too shallow

I found this book to be extremely disorganized. It skipped around way too much and I had the strong notion that the author is not as tech-savvy as she would like us to believe. For example, the part that discusses checking a power supply does not explicitly state, "Do not disconnect the power supply before checking. You have to use back-probing instead. If you disconnect the power supply and turn it on, you may damage or destroy it." Frankly, I thought this book was a waste of money. Try "All-in-One A+ Certification Exam Guide" by Michael Meyers and Scott Jernigan instead. And if you're REALLY serious, throw in "Upgrading and Repairing PCs" by Scott Mueller.
