I worked for the GS for almost 10 years (well, many of those years we were "Best Buy Services" before GS). That paperwork is from Best Buy but is quite old as pointed out. Much has changed in the way they work on PC's.
From my years and years with the company I can tell you a few things about how they do things and why they do and don't work.....
The NUMBER 1 biggest problem with BB/GS is the hiring process! When GS rolled out we were considered a seperate entity from BB, for very good reason! That only lasted a short time and as soon as BB management took over, it all went south. They are more interested in people who can sell their services than hiring people who can actually repair computers. I was one of the few people (out of 17) that could repair computers. I worked in the back of the services area and ran that particular area for many years. I had the choice of who I had working on computers, and I helped schedule them. Now, many stores do not do this! They let every CIA work on computers. I could not let that happen. We would have more than half the computers come back for re-do after re-do if I allowed that.
Number 2 is the pricing structure. As most of you know, their price points and higher than almost all other companies. They SAY its because people are paying for the "expertise" that is provided. This is not true, for the most part. (see number 1)
I worked with many extraordinary technicians that ultimately cared about the customer and did their best to fix their issues right the first time, as I always do. But, the majority of people employed by them are not qualified in any way to repair any computer problem.
Its very sad. I believe that if they had kept all the BB management/corporate morons away from the GS business side, the business structure would be completely different.
Sorry for the long post
