The black screen of the Shenzhou notebook, hoping for the help of the master

There is also a VGA output next to the notebook Take a VGA data cable and connect it to another monitor to see if there is an image If there is, there is a problem with the laptop screen But it may also be the cable of the notebook The contact is not good If there is no image, it means that it has nothing to do with the screen of the notebook, it is likely that there is a problem inside the notebook But no matter what kind of phenomenon it is, you can't get it yourself Even if you can get it right, then you have to disassemble it, but there is no warranty in this way, you still have to find customer service directly.

There are many possibilities.

1. Software problems, kill the poison, and reinstall the system;

2. Graphics card contact problems;

3. Poor contact of the cable.

The last two problems are not easy to solve by yourself, so let's take them to customer service to test them.

Can it be turned on? If you can't, the graphics card is burned, go to customer service, but it will take a month to repair.

If you can turn it on, it's not a hardware problem, just reinstall the computer, ps: There should be a problem with the line like you, it is recommended to go to customer service to repair.

ps2: I heard that the Shenzhou computer can be replaced with a new machine if it is broken three times a year (within the warranty period) PS3: I used Shenzhou, the last time the graphics card burned, it was used for two whole months, and you can't do anything about it in this situation. But yours is a minor issue, and it shouldn't take that long.

Shenzhou customer service is waiting for you. If the cable contact is not good, it should be loose or seems to be in contact with it. Take it and fix it. I'm a computer repairer.

The black screen of the Shenzhou notebook when it is turned on may be caused by the following reasons:

Step 1: Check the power problem.

Old notebooks are prone to low power when turned on due to aging batteries and other reasons. We plugged it in to charge it, and after 10 minutes, we reinstalled it and turned it on.

Step 2: Check whether you have entered sleep mode.

After the computer enters sleep mode, press and hold the power button of the laptop to turn on the computer for 30s, and the computer can usually be woken up.

In order to prevent the laptop from falling asleep for a long time in the standby system, we can open "Windows Settings" - "System" - "Power & Sleep" and set "Never" to sleep.

Step 3: Troubleshoot system issues.

If the computer is infected with a virus, you need to press the power button to restart the computer, and keep pressing the F8 key when turning on the computer to enter safe mode.

In safe mode, disconnect the network and open the antivirus software to check for viruses, then repair the missing system files, and then restart the computer.

If the laptop can't enter safe mode, then try to reinstall the system with a USB flash drive!

Step 4: Check the graphics card, memory, monitor, motherboard.

After trying the above methods, the notebook is still in a black screen state, then start to check whether the memory or graphics card is not in good contact.

Remove the memory module and graphics card after the laptop is powered off, clean up the dust of the slot, carefully wipe the gold finger of the graphics card and memory with an eraser, and then reinsert it back, and then boot it up to test, it can generally be solved!

If there is no response after multiple tests, then it is possible that the motherboard is burned out, and this situation should be sent to a repair station for repair.

If memory and graphics cards are excluded, the next step is to check the display.

If the laptop supports external monitors, find a monitor that is not damaged and connect it to your laptop. If you find that the black screen of the computer no longer appears, then the reason for the black screen is that the monitor is damaged.

The black screen of the Shenzhou notebook may be a problem with the software or hardware. The specific analysis is as follows:

Black screen caused by software.

Sometimes after installing some software or hardware drivers, you find that after restarting, the computer can't enter the system and the screen has been black, which is the black screen of the laptop caused by the software. If the black screen is caused by software, take the Windows system as an example, you can not stop to restart the machine, press the F8 key several times when booting up, and bring up the system's boot options menu.

Once the System Boot Options menu comes out, select Enter Safe Mode. If you can enter the safe mode normally, you can delete the software or driver installed before the black screen in the safe mode. Then restart the machine and see if the laptop can fix the black screen issue.

Hardware-induced laptop black screen. Hardware-induced black screen for the following reasons:

1) The cause of static electricity, sometimes the static electricity will cause the circuit of the notebook motherboard to be abnormal, resulting in no reaction on the screen after the power is turned on. You can try to remove the battery and electrical source of the notebook, and then press the power of the notebook several times to let the machine release the static electricity. Then connect the power supply, turn it on, and see if it can solve the fault.

2) The memory is loose or the memory has a hardware failure. There are several major components of a laptop computer, including the CPU, motherboard, memory, and graphics card. These parts are indispensable, as long as one of them has a problem, it will cause the laptop to not function properly, the most common is that the boot does not respond.

In general, the probability of CPU and motherboard failure is relatively small, and it is more common for the laptop to fail to boot due to loose memory. At this time, first remove the battery and power supply of the notebook, if it is not difficult to remove the computer, you can open the back cover of the notebook by yourself and reinsert the memory. After plugging in the memory, power it on again, start the machine, and see if you can solve the fault.

3) The LCD part of the notebook is faulty. There are some notebooks that are a little older, and this may be the case. Display components generally include displays, data cables, and some other small parts.

If you have a desktop monitor, try plugging it to the VGA display connector on your laptop, and then switch the display to the VGA external display on your laptop. If you can switch to an external monitor, it means that there is a big problem with the display part.

4) The graphics card hardware is faulty, the graphics card is responsible for the source of all the display output of the computer, so it has a problem, and there is no display on the screen. If the graphics card is broken, the average user can't solve it, and the only way to solve it is to find the computer's after-sales service. If the notebook is within the warranty period, it can be taken for free inspection and repair.
