Unfortunately this Lenovo has the same problem of the black line in the top right corner of the screen as every other Lenovo of the same model. Why Lenovo is happy to send faulty products out to customers and damage its name beyond repair is beyond me. I bought this PC because it has the best specification and versatility for the price, which is still quite a lot of money for me. Since my uncle brought it over for me as a special favor from the US to outside of the US it is impossible for me to return it. There seems to be nothing I can do except say that I'm not happy with this transaction. I would appreciate some compensation, though obviously I cannot return the faulty product as I am already outside of the time frame and outside of the country.
