…>> Hello: Do the easiest first, take the host to the neighbor's house with a computer:

1. Turn on the neighbor's display (the notebook can be external) to check whether the display and display data cable are faulty;

2. By the way, you can also know whether it is a problem of virtual connection of your own meters, wires and sockets;

If it is a notebook, if it is not normal here, it is recommended that you reinstall the system, and if it does not work, send it for repair;

5. Only leave the CPU (can be properly coated with silicone), graphics card, and memory module to power on and power on to confirm whether there is a problem in these three places;

6. If it can be normal at this time, it is a problem with the hard disk, please repartition and reinstall the system, or replace the hard disk;

Hello: Lenovo V350 series notebook is a calm business notebook launched by Lenovo in November 2009, a business white-collar notebook. A total of 12 products. Its products have now been discontinued, so weak do not want to take it for maintenance, you can do it yourself, there are ways to check and troubleshoot;

1. Check whether the PC battery pack, especially the power adapter, is working normally, and the power supply is stable and the current is sufficient;

2. Open the fixing bolts of the cover plate of the back cover panel and the heat dissipation area, and then use the low-pressure wind pressure type such as the leather tiger and the small and soft brush to remove the dust, and be careful not to use cloth towels that may hurt the hardware, etc.;

3. Use the HDMI port of the external display (there should be one) and the cable of the external display device to check whether it is a failure of the system graphics card driver, or the body is poisoned and the system data is damaged, update the latest official graphics card motherboard and other drivers, and carry out virus detection and killing in safe mode Then it is best to redo the windows operating system;

4. Do it yourself and replace the graphics card, motherboard and other hardware online shopping, this depends on your knowledge of the computer (not recommended).

In fact, you still get the corresponding qualified after-sales service outlets or professional repair shops to see the repair ** and repair value, if you do not meet your psychological expectations, you have to retire him with honor.

If you can hear the boot sound, first connect the external monitor, if it is normal, the screen is broken.

Or the graphics card is broken.

Common reasons: First, the memory is loose or there is a problem with the memory itself, try to reinsert the memory or change the root memory;

Second, the motherboard power supply chip is soldered or aged, the screen cable is loose or the motherboard short-circuits the screen power supply circuit;

Third, the graphics card, south bridge, and north bridge BGA packaging chips are soldered or damaged, and there are generally more cases of virtual soldering, so it is good to add soldering.
