There is evidence of ghosts in the world.

1) In the United States, scientists have done an experiment. They found a man and hypnotized him, and he was able to tell him what he was like in his past life and what he was like in this life!

2) A friend of mine died in such a tragic way. She was bored at home and used her own home** to dial her own home**, and after many times she finally dialed, she heard a hollow sound, like an echo valley and the sound of water droplets. She disappeared the next day, and three days later** found my friend's body by a pool in Echo Valley.

3) One night I was going home with my friend after dinner at twelve o'clock, passing by a place with a grave, and my friend was scared. As a result, the next morning he was in high spirits, and often said these words: Someone has crawled out of the grave. They were laughing. They are bleeding.

4) There was a power outage in my house one night, and it turned out that there were only white candles to look for and sleep, and I looked in the mirror behind the bedside to sleep, but that day I felt tightness in my chest, I couldn't breathe, and I looked over and over as if I was pressed by something, and after looking in the mirror, I found that I was carrying my grandmother's bag! I obviously didn't carry it!

5) The whole lake turned red (it was blood), a hand was stretched out from the lake, grabbed the girl's feet, and forced her into the lake, and then, people found the girl's body and clothes 100 kilometers away from the forest, but her head was missing, people opened her backpack, frightened, the bag was her head, her expression was very painful, and the people who found her abandoned her body in the forest, and then left, and since then, no one has dared to go to that forest.

If you read this post, please reply immediately, reply to "Bodhisattva bless", and then post this in three copies of Don't**, (excluding me) If you don't send it, that hand will stick out when you take a bath, and you will end up the same as that girl! Believe that everything is true.

Typing is not easy, such as satisfaction, hope.

1. The boot line is abnormal: use an external power supply to supply power to the mobile phone, use the electric meter to detect whether the indication has changed, if there is no change, it is likely that the boot line is broken or the boot button is not in good contact.

2. The power supply circuit of the battery is abnormal: use the external interface to supply power to the mobile phone, see if it returns to normal when it is turned on, if it is normal, it is determined that the power supply circuit of the mobile phone is abnormal.

3. The IC of the mobile phone power supply is abnormal: test the test point of the peripheral circuit of the power supply IC according to the circuit schematic diagram to see whether the test value is normal.

4. The system clock and reset of the mobile phone are abnormal: you can use the dual total oscilloscope to detect the CPU power supply of the mobile phone to check whether the waveform in the reset is correct.

5. Problems with logic circuits: that is, faults in the circuit version of mobile phones, which can generally be solved by repair welding.

6. Software conflict: The installed software does not match the system of the mobile phone, which may also cause the mobile phone to fail to boot, you can connect the mobile phone to the computer to delete the program.

7. If it is a copycat mobile phone, then I estimate that it can't be turned on because the chip inside is burned, or some of the small parts inside are loose, but this situation will only appear if you drop it, the chip burns may be because you charge it for too long, burn the chip, if the battery has electricity, that is these aspects, if it is a brand-name mobile phone, such as Nokia, Motorola. These situations are rare, unless it is artificial, if it is a brand-name smartphone, and it is not used improperly, it is a software problem, it may be a system crash, or because of the mobile phone poisoning caused by software damage, generally this can only go to the maintenance office, however, I think the biggest possibility is caused by static electricity, it is recommended that you do not open the blind repair, or go to the maintenance office!
