Hello, this problem is not very good to solve, generally go to the outside repair department, rarely give you repair, most of them are direct replacement of hardware: that is, your power chip is broken, do not give you repair, directly change the power to you.
When the graphics chip is broken, replace the graphics card directly.
If you are a brand machine, I recommend you go directly to the official maintenance department to see if they can repair you without replacing the hardware. Of course, there are repairs outside, but I did not ask the price, I estimate: power chip 80 yuan, graphics chip also 100 yuan, a total of 180 yuan.
