oppor9t can t turn on, oppor9 can t turn on, what should I do

Method 1: It cannot be turned on after turning off the power when there is power.

1) It is estimated that many people encounter my situation: it is turned off when there is power, but rebooted after a period of time, and found that it can't be turned on, and when charging, it won't light up, and it is more likely that the smart phone is an integrated battery and can't be taken off, is there really no way? Do you have to go to a repair shop?

Not necessarily, see below.

2) In this case, it may be because the system is not very stable, in order to successfully solve this problem, plug in the mobile phone charger (it is best to charge directly, which is better).

3) At this time, the charging indicator may not light up, but make sure that your power connection is usually sufficient. Then press and hold the "Power Key" and "Volume +" keys at the same time until the phone vibrates more than 3 times.

4) Press and hold the power button again to power on and see if it solves your big problem? I'm using this method here to successfully solve my own problem. Hopefully, this will be a useful way for you to boot up.

Method 2: The removable battery that cannot be turned on after the power is turned off in the above method 1, because it is an integrated battery, it feels not so powerful to solve, and it is easier to solve it in the case of non-integrated battery here. Remove the back cover of your phone.

Remove the battery, then put the battery back in, turn it back on, and see if that solves the problem? If the problem is not solved, try the solution of method 1 to see if it has any effect?

Method 3: Charge the battery for a period of time before turning it on Under normal circumstances, if the phone is not suddenly destroyed by water and other accidents, the battery and the phone are not problematic, you only need to plug the charger into the socket, according to the usual experience, ensure that it has been connected, regardless of whether it is lit or not, charge for about 20 minutes, and then turn on the phone to see if it solves the problem.

Method 4: Poor battery contact If you know that your phone is charged, then it may be caused by poor contact between the phone battery and the phone, this situation is easier to deal with for non-integrated batteries, cancel the battery, and then use the wiping thing to wipe the contact metal part of the battery, and then reinstall the battery, restart the phone, and see if it solves the problem?

Method 5: If the mobile phone charger is used for a long time, the data cable may be broken due to repeated bending, especially the wire at the socket, which is often bent and easy to break, try to change the charger, it is best to match, because different models of chargers may not support your mobile phone.

Method 6: The above methods are invalid, there are so many solutions that can be thought of, if your phone still does not solve the situation that it cannot be turned on, you can consider whether you can repair it. You can also search for other solutions, which may be able to solve your problem.

1. Mobile phone crash memory problem: Under normal circumstances, when the mobile phone stores too many things, many friends can feel that the mobile phone is running too slowly, and when their mobile phone is occupied by 80% of the memory that can be driven, it may crash.

2. The problem of the second contact of the mobile phone crash: This is the loosening of the contact of the mobile phone screen, which is not a big problem, but it can directly lead to the black screen of the mobile phone, which is difficult to find and can only be found after a lot of tests, which is generally caused by the mobile phone being bumped.

3. Mobile phone crash three battery problems: It is common for many mobile phones to have a black screen after using it for a long time, the main reason is that the effective use time of the mobile phone battery is 1 year, or it is three years but there is a problem in one year, and excessive use leads to the aging of the mobile phone's battery and insufficient voltage.

4. The problem of four conflicts in mobile phone crash: There are many applications for smartphones nowadays, but there are some software that are born with conflicts, which can also lead to a black screen, so the black screen after installing a lot of software is basically this reason.

You can press and hold the power button for 15 seconds to force shut down or restart it.
