maintenance repair and upgrading

This book is a rambling bunch of garbage with no true criteria to help a technician. With jumble facts to find utilization of repair and upgrading computers, it is hard to make sense of it all. I a recommend all of Bigelow's books

A generally useful text that is like a supplement to this series' Complete Guide to Upgrade and Repair, and though it rates a general five stars, in my opinion, it is more like a slightly outdated manual for the rapidly advancing industry. I don't know how any large books can keep up with this field, because by the time they are written and published most of the equipment they cover will be outdated. This is like a background text and you have to go to the web sites to view the latest information and changes. You have to do your own work, at some point, and can't have it spoon-fed to you. I'd recommend the book for this price and don't agree with the fellow who gave it two stars, which is a very harsh rating and speaks of superiority in a way. All of us regular guys will find the book useful.

Even though this is the 4th edition and was just published this January, I still found there are a lot of out-of-dated information in this book. The author has referred a lot on the very old system, such as 8086, 80286... but give very little information about the new systems. For example, the author even didn't mention the use of DIMMS in the memory chapter but solely mentioned EDOs or previously released memory.
