The failure of the phone not turning on may involve:

Poor contact between the battery and the device;

The battery is low, or damaged;

system failures; Power button or hardware motherboard-related failures;

1. Disassemble the battery and try to restart it (if the battery is not removable, you can try to press and hold the power button for more than 8s, or operate the reset button of the device). If it is caused by poor battery contact, you can try to plug it tightly with a small piece of paper;

2. If the battery is exhausted, you can use the standard charger to charge for 30 minutes, and press and hold the power button to try; There is a spare battery, which can also be replaced for testing;

3. If the previous operation involving the system level (such as root to obtain permissions, brush third-party firmware) caused by the abnormality, you need to recover by flashing, there is a risk of flashing the machine by yourself, if the failure leads to the failure of the equipment, it may affect the normal warranty service of the product, it is recommended to contact the maintenance station to let the engineer assist in the flashing operation, if you are willing to bear the possible risk, you can go to the Lenovo official Lewen bar firmware area**Official firmware and detailed tutorial, according to the flashing tutorial to try to operate.

4. If the power button is out of order, damaged or the hardware motherboard is related to the fault, you need to take the time to go to Lenovo after-sales service for engineers to further detect and deal with it.

We recommend trying the following:

1. It may be that the battery is not turned on due to the lack of power, and it will be retried after charging for half an hour.

2. Disassemble the back cover of the phone, remove the battery and restart it to see or wipe the metal contacts of the battery with alcohol before trying again.

3. Check whether the data cable is unusable.

4. If it can't be started but stays on the boot screen, you can restore the factory settings through Shuangqing.

1）.In the power-off state, press and hold the power button and volume + buttons of the phone at the same time.

2）.Release the keys when the screen lights up and wait for the recovery mode to enter.

3）.Use the Volume+ and Volume—keys to adjust the bright bar to "Wipe Data Factory Reset", i.e. "Clear Data Restore Factory Settings", and press the Power button to confirm.

4）.Use the Volume+ and Volume—keys to adjust the light bar to "yes, delete all user data" and press the power button to confirm.

5）.Wait for a while until the screen appears, select "Reboot System Now" to restart your phone, and press the power button to confirm.

6）.Wait for your phone to reboot into the system.

5. If there is an abnormality caused by flashing the third-party firmware or damaging the system after rooting, you need to re-flash the system to restore the use of the system. (Professional operations need to be carried out by professionals).

6. If it involves the power button itself, or the motherboard-related abnormality, go to the local Lenovo after-sales service for maintenance.
