Dear Lenovo users, it is not recommended that you flash the mobile phone operating system by yourself, the use of unofficially provided operating systems may produce incompatibility problems with mobile phone devices, affecting the normal use of mobile phones, and at the same time, you will not be able to provide warranty services after flashing your own phone, which will bring inconvenience to your use and maintenance.

The rom bag is not good, go to the wood ant to look for it.

Hi 2, please flash according to the flashing tutorial, flashing tutorial:

Hope it helps.

Thank you for your support and have a great day!

If the screen flickers due to liquid ingress, it is recommended to send the phone to the site for further repair.

It means that it may abandon you.

You see if your surroundings are flickering and dark, and sometimes the laptop adjusts the brightness of the screen according to the light sources around it!

You can press and hold the start button and then press the x button to see if you can bring up an interface with a light source sensing or something.

It may be that there is a problem with the screen backlight or it is aging.

Dear Lenovo users, hello!

After powering off, unplug the battery and adapter, press and hold the on/off key for 5 seconds, release the static electricity and then install the battery and power it on. If the fault persists, it is recommended to find a repair station.

The screen flickered because of an issue with the screen refresh rate setting:

The workaround should be divided into two cases:

1. If it is an ordinary monitor.

Right-click on the empty space on the desktop Properties - Settings - Advanced - Monitor, and change the refresh rate to 75 Hz or higher. Click the "Apply" button and confirm the exit. Debugging is based on your own display.

2. If it is an LCD monitor.

Right-click on the empty space of the desktop Properties - Settings - Advanced - Monitor, and change the refresh rate to 60 Hz. Click the "Apply" button and confirm the exit.

1. Splash screen caused by screen backlight.

Cause: This situation occurs due to the instability of the high-voltage board that supplies power to the screen backlight or the solder joint connection at the lamp joint is not strong and ignites.

Solution: Replace the high-voltage plate to solve the flickering screen.

2. The flashing screen caused by the motherboard charging switching circuit.

Fault performance: When the battery and power adapter are used at the same time, the laptop will flash from time to time, and the charging indicator in the lower right corner of the screen will be switched constantly, and the fault phenomenon will disappear when a single power supply is used.

Solution: Repair the components of the motherboard's charging circuit to fix the fault, or replace the power adapter.

3. Screen flickering caused by the defect of the screen itself.

The specific fault performance is: Generally, there will be a bright line under the laptop screen, and after a while, the bright line will evolve into a full-screen flash.

The solution: can only be replaced with a new LCD screen.

2.If the external monitor sees that the system has been started normally, check the switch above the notebook keyboard for turning off the power supply when the display screen is closed, a contact switch that can move up and down, press it many times, shake it gently, and see if it is caused by the failure to bounce up normally after being pressed, resulting in the display not being able to supply power;

3.If the external monitor cannot be displayed, and the power-off switch of the pop-up display screen cannot be displayed, it may be a system problem;

They may have a problem with the system they installed for you, right? I recommend being cautious about installing various drivers downstairs, I installed the graphics card driver before and then the computer was garbled

It should be a problem with the graphics card driver, and it is recommended to use the driver wizard to reinstall the graphics card driver.

Memory reason:

Try the following.

1. Remove the memory and wipe the gold finger of the memory with a clean eraser (wipe it outward in the direction of the gold finger) 2. Insert the memory into another slot. (If there are multiple pieces of memory, you can plug them in one by one and try to boot them first.) Graphics card reason:

1. For a discrete graphics card, refer to memory.

2. Remove the graphics card and wipe the gold finger with a clean eraser (wipe it outward in the direction of the gold finger).

If the system is damaged, redo the system flash to go.

In this case, you need to replace the charging cable and try again.

At present, the battery is almost exhausted, and if the data cable is not good, it will turn off when it is turned on.

Replace the data cable and try again.
