Thank you very much, Josh!

One question.
About **  how can I express the following in writing?

・Because I am a computer illiterate
・The important things for me is that a PC company provides good after-sale service
・I don't care much about the brand name of PC if the PC is a kind of the latest.

 

Good service, Good return.

One of my laptops, a DELL (almost 3 years old) , hasn't been in good condition and I frequently have to call the support center. Whenever I call their toll free number, Chinese people answer it.
Why are there so many Chinese people  working there in Japan ?

The trick is that the line goes overseas to Dalian in China where there is a DELL support center for only Japanese customers. It was built in 2002 as part of a cost reduction. There, 500 Chinese people are working; who possess great computer skills and speak the Japanese language based on Japans business style. Amazing!

I knew that the DELL service in Dalian had somewhat of a bad reputation in customer support before; But now I don't see much difference between the domestic service and the one in Dalian.

I don’t deny that I am a computer illiterate who needs better support in selecting the type of PC that is best for me

The support center is a crucial department which makes it an easier way to get potential repeaters more than in the sales department. 
People who complain could turn to be a big fan of the company if you treat them very carefully; to solve their problems as quickly as possible, or sometimes just to listen to their complaining without objection.

See, I have got another new laptop. But I have been supported by Japanese senior assistants because the one I chose was for business users. I now miss Dalian very much.

Good service, Good return

One of my laptops, a DELL that is almost 3 years old, has been giving me problems and I frequently had to call the support center.  Whenever I called the toll free number, Chinese people answer it.   Why are there so many Chinese people working there in Japan?

The catch is that the call goes overseas to Dalian in China where there is a DELL Support center for Japanese customers.  It was built by Dell in 2002 to reduce costs.  There are 500 Chinese people working there who are all great with computers and able to use business-style Japanese.  Amazing!

I used to hear about the bad reputation Dell had for customer support in their Dalian center, but now I don't see any difference between their domestic service and the one in Dalian.

I won't deny that I am computer-illiterate and need more support than simply selecting the latest type of computers. 

( Note:  What exactly do you mean?? I am computer-literate and I do not understand what you are trying to express here....)

The support center is critical gaining repeat customers; it is much easier than going through sales.  It is well-known that complaining customers can turn into big fans if companies treat them well and solve their problems quickly.  Sometimes, all they need to do is listen carefully to their complaints.

Note:  Your english is great over all. :)  The sentence I marked with the ** is unclear.  I corrected what I could, but I don't want to change the meaning of the sentence.  The part in orange is the most unclear.
