What should I do if I don t turn it on, what should I do if I can t turn it on?

Specifics??

The fan doesn't turn because your power supply is not plugged in.

If you use a vivo mobile phone and it does not turn on due to a crash or liquid ingress, it is recommended to bring the mobile phone to the vivo customer service center for processing.

If the screen does not turn on when the device is turned on, the phone does not vibrate and other reactions:

1. Check whether the power is sufficient, use the original charger and data cable to charge for more than half an hour, and try to turn on the machine again;

2. If the keys of the mobile phone are stuck, broken or liquid, please bring the mobile phone to the vivo customer service center for further maintenance.

If the phone screen is on but you can't enter the desktop:

1. You can try to force restart the device to resume use;

Ways to restart your phone:

1) Press and hold the power button of the mobile phone to pop up the "Restart" option to turn it off;

2) Slide down at the top of the mobile phone screen to bring up the shortcut details page twice The bottom of the screen slides up to enter the control center, and click the "Shutdown and Restart" switch;

If the phone vibrates when turned on but the screen does not light up:

When the phone vibrates when you press the power button to turn on or force restart, but the screen does not display the screen and the screen is still black, it is more likely that the screen is faulty, please bring the phone to the vivo customer service center for further maintenance.

If the laptop won't turn on, there is a problem with the power adapter. If the desktop can't be turned on, it's a problem with the case power supply!

May I ask if I can't get into the system or can't turn it on?

If you say something specific, if you can't install the system, it's OK.
