Microsoft has good after-sales service. Don't send it to an unofficial and informal repair shop, or you will lose your warranty qualification. Just send it directly to Microsoft after sale, as long as they will give you a new one for free during the warranty period. Open the Microsoft Online Service Center/,click "Equipment Problem", briefly describe your problem, and then you will be asked to fill in some information, the most important thing is the detailed address and contact number. Generally speaking, FedEx will call you the next day and ask when you are free for them to pick up the goods. Then the courier will come to your home to pick up your surface, and you will receive a new surface in a few days. The premise is that you must register your device in Microsoft official website. The registration method is to right-click the properties of this computer on the desktop, click Online Support, and click Register New Products under My Surface.
