The best resource/guide out there! I know how to fix notebooks and PCs but sometimes you could be lost or not on the right track and that's when a book like this one comes in handy. Also, the author links each troubleshooting step in the book to great pics posted on his website. The website also gives you some extra valuable tips. I highly recommend this book to anyone. Why? Because you don't know EVERYTHING and ANYBODY can make mistakes and need a little help or guidance. Great job!
