I also used it for three years, and I changed the battery myself... A week later, at the beginning of the splash screen, then stripes Finally the white screen, the information screen is opened a few more times and it is restored, and then I want to press the row and say that the external screen is cracked to change the external screen first and then press. And then I took it down myself, pulled out the motherboard and wiped it, and I got better again a day, and I don't know how long it will be better
