The pictures are outstanding and descriptions and instructions are very helpful.  But if you don't know the name of a particular plant or tree, one has to go page by page to find what one is looking for.  Good luck.  Don't know what the solution is.

The processor on the computer was small and I should have been more computer savvy. I was not able to return it after I opened it and found out that it had a small processor. Operator error I guess.

This book is for professionnals who are always in a hurry to take care of computers. You've got the essentials and no more. But you find easely what you're searching. And it's more valuable than more accurate informations.

Did not work for me. I gave it a three stars for the benefit of the doubt that it might be my laptop but I highly doubt it.

This book was somewhat helpful when it came to figuring out my computer failures. As Apple developed more reliable machines it was not needed.

When professionals need to determine the problem with a computer, they need to do so quickly and efficiently.  Information is king, and when a laptop is nearly dead, it is rather silent about the things that give it problem.  This tool is ABSOLUTELY NECESSARY for anyone who is the least bit serious about computer repair.  It eliminates the need of someone guessing and trying to swap out things.  I never understood that approach, when the equipment is so readily available.

One of the technical staff at Mentor Computers has already tested this out thoroughly, and it is not just my opinion, but the unit works well.  It fits nicely into the appropriate slot, but I have found that sometimes the entire back panel needs to come off to service a laptop not made for this.  Now remember that you will need to know what the POST codes mean.  This is not like STAR TREK where the computer is going to tell you verbally what is wrong, but this unit works just like the units made decades ago for Desktop Computer.

I heartily recommend this unit.  I purchased two of these, and not because we might have so many laptops requiring this tool at the same time but because the price is insanely wonderful AND I don't want to be looking for these units either.  I think that I am going to buy a few more and make sure that I have one in each Technicians Resource and Out Of The Office bag.

Excellent unit at an excellent price - but again, you are buying this unit and NOT the wisdom of its use.  It is simply going to give you CODES that need to have some meaning to you.  BUT, the BIOS companies are very helpful here.

If your experiences are different, I would like to know.  As I said, I am thinking of buying a number more.  I am only waiting until everyone on staff has had the opportunity to try this unit while repairing the various makes and models that come through our technical shop.

There is no gamble here !!  Buy yours today !!  I recommend it heartily !!

It works fine, but the cord is too short and the connections are loose, so you may think the cord is plugged in, but if you're not paying attention, it may have come loose, battery has run out, and computer dies.

It worked as advertised.  Was able to find problems in the computer and correct them  by using the diagnostic test board
