　　I bought a Dell Inspiron 7520 laptop on June 24, 2017. According to the salesperson, the laptop could serve my needs very well. Therefore, I bought the Dell laptop without hesitation.

　　On the night of July 16, less than a month after I bought the computer, I closed the laptop’s lid after turning it off. As there was a heat sink under the laptop, I lift the lid upward a little bit using both hands, but suddenly felt something went wrong at the areas where my hands touched the screen. I immediately turned on the computer, and found there was a crack(裂缝) on the screen. The area above the crack was all white, and the remaining area remained normal.

　　I felt the problem was caused by damage to the cables and wires inside the screen. I dialed Dell’s customer service hotline the next day, but the customer service representative said it was physical damage, and suggested that I contact the company’s after-sales service center in Dalian for paid repair. Afterward, I sent an e-mail to Dell China抯 Technical Support Department, and the reply was that it was not covered under warranty(s保修期内) and I had to pay to have it repaired.
