"Three minutes to see the weekly digital technology information hotspots"
When your smartphone won't turn on or can't be charged, it's probably the creepiest time! Sometimes you can easily tell which part of your phone's story failure might have come from, but you still can't tell why your Android phone won't turn on in the first place.
There are many reasons why your Android phone won't turn on. But as a professional phone repairer, I divide it into two types: one is hardware damage, and the other is software failure. In fact, for the vast majority of software problems, you can fix them yourself, only special hardware problems need professional help.
Below I will guide you through some things related to fixing a phone that won't turn on.
Four steps to repair your phone:
i. Try to fix the charging problem
If your phone won't turn on, the first thing you have to do is fix the charging problem: charger, USB cable, charging port, and power outlet. The easiest way is to find a usable Android phone and use it to try to use the original charger of your broken phone, all you need is to troubleshoot it.
ii. Continue to charge the phone that won't turn on
One of the common reasons many broken Android phones won't turn on or charge is that their battery has run out to zero. So in this case, we need to plug the phone into a charger that can be used and let him charge for half an hour, or charge for up to two hours. In this process, if the phone has a charging indicator, it means that the charger is working, and if the screen lights up during charging, it is lucky.
iii. Try to force restart your phone
If your phone still won't turn on after more than 30 minutes of charging, you'll need to force a restart at this point. All we need to do is press and hold the power button for 8 to 10 seconds or press and hold the power button at the same time and turn the volume down or turn down the button for 8 to 10 seconds.
iv. Check the screen for problems
If the previous steps are not useful, we need to diagnose whether the mobile phone screen is malfunctioning. First press the power button for 10 to 30 seconds to try to restart the phone, wait for a few seconds, we need to listen carefully to whether our phone vibrates or makes a startup sound. If not, you need someone to call you at this time, if there is a sound at this time, then the screen may be the problem. If you notice a malfunctioning screen, you can go to a professional repair shop to repair it.
The above situations are the simplest approach, so if you have a multimeter at home, you can actually use it to help you diagnose or repair your broken mobile phone If you really don't know how to operate it, then most of the time is a hardware problem, then you can only go to a professional technical staff to help you troubleshoot it.
In many cases, as long as the phone is not shut down due to improper use, in fact, the official service provider is likely to help you repair the Android phone that cannot be turned on for free. You can visit the official service center for help.
