If you are in the digital city, you should look for Kechuang.
The Lenovo general agent in Yiwu is made by Kechuang Computer Company. I bought my two front lines in 2007 and 2008 at the Science and Technology Lenovo Store in Computer City.
Address: computer city D2-36~39, Yiwu Communication Market,
In fact, as long as you go to the second floor of the computer city, just find a shop and ask where the Lenovo computer store is, and someone will usually tell you. Because there are only a few passages on each floor.
Technical service telephone: 85563909/85563228
Hardware maintenance: 800-8 10-8888
If the camera and driver are software problems, there will be a charge after the warranty period.
If it is a hardware problem, you may have to ask Lenovo maintenance personnel face to face.
Computer City is the storefront of the dealer Kechuang, and they have their own software maintenance personnel.
Hardware maintenance should find Lenovo's own official repair shop. Just Zhao Zhai's.
That's about it. You can call for advice first.
