Hello, I bought a Dell laptop on 06/29/2019 (Order Date) and the order number was BBY01-805630793059 (ORDER #). The laptop was delivered on 07/04/2019. It was an open-box, according to model: "Open Box - Dell - Inspiron 13.3" 4K Ultra HD Touch-Screen Laptop - Intel Core i7 - 16GB Memory - 512GB SSD + Optane - Black Model: I7390-7100BLK-PUS SKU: 6339272 Condition: Certified ". The computer was received by my sister, who was vacationing in Orlando. On 07/14/2019 my sister returned to Brazil and gave me the computer. From the beginning I noticed that he had a small scratch on the screen and also one near the keyboard. I am very disappointed with Best Buy, because even though I knew it was an open-box, I believed that it was at the Excellent level (Open-Box Excellent - Certified). Despite the sadness, I decided to turn on the computer. Everything seemed fine and I started to do the Windows configurations. However, when I was on the screen to put the wifi network, the computer simply shut down. I thought it was the power plug, but I checked and it was working. I turned on again and restarted the settings and again it hung up. I repeated the process several times until I was able to configure Windows. I started using windows and again it shut down. I noticed that it is getting very hot and that the cooler makes a lot of noise. I believe that the shut down should have something to do with it. I tested it in "cabin" mode with the nearby air conditioner and managed to leave it agum time without turning off. However, when I put it in normal mode it shut down in less than 5 minutes. Unfortunately I live in the state of Amazon, Brazil, and I have no idea what could be done. I would really appreciate your help. I'm very regret I bought the open-box. I believe it would have been much better to buy the band new version. Please help me find a solution for this.
