Problem: The Huawei Mate 20 Pro does not light

Hello, I use the Huawei Mate 20 Pro for a month and, from nowhere, I've used it, then I've locked it and pressed once on the button. power to unlock it after using it for at least 3 minutes. died on me. I do not know what to do with it now because it does not turn on, no matter what I do. I've tried to connect it to a computer or to the original AC adapter and still nothing … nothing happens.

I'm really disappointed because I really like this phone. I hope you have some advice or know how to solve the problem. Thanks a lot 🙂

Solution : If your Huawei Mate 20 Pro suddenly responds and does not turn on anymore, it is possible that an application or software bug is causing it. If the device fails to power up after a fall or physical strike, skip the software troubleshooting and proceed directly to component repair by calling Huawei.

Try another set of loading accessories

This should be the first thing you want to do. If you have another set of USB cable and adapter that works, use it to charge the device. The USB cable that came with your device consists of tiny wires that can break easily. The more disconnected wires inside, the more energy transferred from the adapter to the phone is low during charging. This can lead to a loss of fast charging capacity and possibly the cable becomes unusable.

If possible, visit your local Huawei store and charge your device with the original charging cable and adapter.

Forced Reboot

Temporary bugs can sometimes freeze a device, giving the appearance of what you are currently experiencing. On older devices with removable batteries, a problem like this can be easily solved by removing the battery. This is not possible for a Huawei Mate 20 Pro, so you can only simulate the effects of a physical disconnection of the battery. Before performing a forced restart, be sure to leave the phone on charge for at least 30 minutes. Then, press and hold the Volume Down and Power Down buttons for about 10 to 20 seconds until the phone restarts.

Check if this is a screen problem

The next troubleshooting step you want to perform is to check if the phone is totally dead or there is a problem screen. This is done by looking for signs of life. If the phone beeps or vibrates when you try to restart it, these are signs that it is not responding fully. You can also try calling your number from another phone to see if your phone is ringing or vibrating. If this does not show that it is not dead but the screen remains black, there must be a problem with this screen.

Restarting in safe mode

To see if a downloaded app is preventing Android from starting correctly, you can try restarting the phone in safe mode instead of normal mode. In this mode, all downloaded applications will be suspended. Thus, if the phone starts correctly in safe mode, you can bet that you have a problem with the application.

Press and hold the power button.
Release the power button and hold down the volume down key. (When you see Huawei animation)

Do not forget that safe mode blocks third-party or downloaded applications. If the problem goes away in safe mode, you can bet that one of the apps is to blame. To identify which of your downloaded applications is causing the problem:

Quit safe mode by restarting your device.
Look for the problem.
If the problem reappears, restart in safe mode.
Uninstall an application. Start with the last downloaded.
After each deletion, reboot your device and determine if removing it resolves the problem.
Repeat steps 1-4 until you have identified the culprit.
After removing the application causing the problem, you can reinstall the other applications you removed.

Charge via computer (optional)

Some Huawei Mate 20 Pro have been able to solve charging issues by charging their device to a computer for a few hours. If you have not tried it yet, be sure to leave the device connected to your computer for a few hours to see if there is a difference.

Charge with the aid of a portable charger (powerbank)

In addition to charging with the help of a computer, you can also check the operation of the device when it is charged via a battery backup. If you have a powerbank, be sure to let the device charge for a few hours.
