First of all, I don't know what brand your notebook is! If it is Lenovo, Dell must be on-site service in the first year. If it still needs to be repaired, there is something wrong! In addition, I suggest that you'd better call the regional after-sales phone of the notebook company to ask clearly, which is more reliable! For example, if there is an after-sales store in the provincial capital, you can also repair it yourself (many specialty stores also suggest that you take your computer to the after-sales store). If it is a prefecture-level city, he is talking about sending it to the after-sales point. Go back to the factory! You don't have to go back to the factory for such a problem. Your problem is the screen, so change the screen!

It doesn't matter if there is a packing box for repair, but of course I have to give you a certificate of repair. What you said may not change much. You can write down or photograph the models of the motherboard, memory, CPU and network card for protection. These are unique, you can compare them when you take the machine!

If the important information in your computer is very important, since you are on the turntable, delete it and upload it to your computer. Be careful!
