How to solve the problem "Huawei Mate 20 does not boot"

Before performing any of the recommended troubleshooting procedures on this phone, it is best to make sure it is running with the latest software version. If an update is available, I suggest you download it and install it first. This will at least minimize the possibility that the problem is caused by an obsolete version of the software.

Make sure the charger is working

The first thing you will need to do in this case is to make sure that the charger you are using works. There are two parts that make up the phone charger and these are the USB charging cable and the adapter.

The cable is easily damaged as it is usually folded and rolled, so it is best to try using a different charging cable. You should also try using a different adapter to charge the phone if the use of a different cable does not work.

Charge from a different socket

There are times when the problem may be caused by a non-functioning outlet. To eliminate this possibility, you should try connecting the charger to a different outlet. Note that it is better not to connect the adapter to an extension cord but connect it directly to the power outlet if this problem is encountered.

Check the phone charging port

Dirt or debris stuck in the charging port of the phone can usually cause charging problems. Make sure the phone charging port is free of debris by blowing air towards it. If the charging port of the phone is wet, it must be dried before leaving the phone in a cool area for a few hours.

The liquid in the door will naturally evaporate. Check if the problem "Huawei Mate 20 does not boot" still occurs.

Try charging your phone from a USB port on your computer

If you cannot charge the phone using the wall adapter, try connecting the phone to a USB port on the computer. The phone will continue to charge this way but it will be a slower process.

If your phone charges, then there must be a problem with the fast charging pin on the phone charging port. You should try cleaning this pin or have it checked by a service center.
