Solution:
1. The built-in battery of the newly purchased computer needs to be activated before it can be used. For the first time, the charger in the package needs to be used for effective power supply, and then press the power button to turn on the computer. In addition, the feel of the power button is different from that of ordinary buttons, and it has been separated, so you need to pay attention and press it in place.
2. If you purchase Xiaomi notebooks with different chargers at the same time, you need to use their respective chargers for power supply when you turn on the laptop for the first time.
3. Please enter the BIOS to reset the initial BIOS settings (press F2 to enter the BIOS when the MI LOGO appears on startup, press F9 in the BIOS interface, then press F10 again to save and exit).
4. If the screen is still black and cannot be turned on, please go to a nearby after-sales outlet to deal with it.
