Sometimes our laptop screen flickers, what is the reason and how to fix it? There may be many guys who don’t know it. Let me briefly introduce the reasons and solutions to the flickering lines laptop screen for you. I hope can help you!There are four common reasons why laptop screen blinking occurs:
First, check whether the power cables of the host and the display are connected firmly. If they are loose, this kind of splash screen will appear. If the laptop screen flickers when you move the lid, there's also a good chance that there's a loose wire inside. Serious bumps or aging after long-term use will cause the internal cables to loosen and cause a series of glitches.
Whether the cable connecting the monitor has no shielding coil, if there is no anti-interference black protrusion, it will also interfere with the screen. What is the process of QQexternal.exe, also check whether there is interference nearby, such as high-power audio, power transformer device. Displays are easily disturbed by strong electric or magnetic fields, and sometimes screen shake is caused by magnetic or electric fields near the display. In order to eliminate all interference around the monitor, you can move the computer to an empty table around it, and then perform a boot test. If the phenomenon of screen shaking disappears, it means that there is a strong electric field or strong magnetic field interference in the original place of your computer. , please keep suspicious things (such as subwoofers of speakers, magnetized cups, etc.) away from the computer. Then turn off the monitor and turn it on again several times to achieve the purpose of degaussing (now the monitor has an automatic degaussing function when it is turned on.
Right-click on the desktop -> Properties -> Settings -> Advanced -> Display -> Screen refresh rate, adjust the CRT to 75Hz or more (the LCD of the notebook LCD screen can be adjusted to 60Hz), in fact, the main reason for the monitor screen jitter is the monitor refresh rate setting is lower than 75Hz. Screen jitters and flickers frequently. We only rescale the refresh rate. If it is higher than 75Hz, the phenomenon of computer screen shaking will no longer occur.
If your Windows 10 monitor flickering on and off, then it's most likely caused by a driver bug or incompatibility. Check whether your display card is loose, try to uninstall the computer's graphics card driver, and install the stable version of the driver. Sometimes when we enter the monitor refresh rate of the computer, we find that there is no refresh rate to choose from, which is caused by the incorrect or too old driver of the front graphics card. Computers purchased earlier are prone to this problem. At this time, do not use the drivers in the CD-ROM that you purchased the computer. You can download the latest version of the driver for the corresponding graphics card from the Internet, and then open the "System" property window. Click the "Device Manager" button in the "Hardware" window to enter the device list interface of the system. Right-click the display card option in this interface, click the "Properties" command from the pop-up right-click menu, and then in the pop-up graphics card property setting window, click the "Driver" tab, and then in the corresponding tab page Click the "Update Driver" button, and then gradually update the graphics card driver to the latest version according to the wizard prompts, and finally restart the computer system. If the driver is installed properly, the display refresh frequency selection item will appear, and then refresh the The computer screen flicker can be solved by setting the frequency above 75Hz.
The components used in many brand-name computer power supplies are of poor workmanship and materials, which can easily cause the computer's circuit to be unsmooth or its power supply capacity to fail to keep up. When the system is busy, the monitor will especially shake the computer screen. The power supply must be replaced at this point.
Occasionally, jitter may also occur due to the age of the monitor being used. In order to check whether the electronic components inside the display are aging, you can connect the faulty display to someone else's computer for testing. If the fault still disappears, the display is broken and needs to be repaired.
Some computer viruses will disturb the screen display, such as: character inversion, screen shaking, graphics flip display and so on. You can download some free or premium antivirus software and give it a try, if this is the problem, your laptop screen should stop flashing black soon.
Tips: Long-term screen flashing will also cause great harm to our eyes. If there is a flashing problem on the screen, it should be repaired in time.
The optical disc drive(abbreviated as ODD) is an important hardware component in the laptop computer. It is defined as a machine used by a computer to read the contents of a disc. In the past, when CDs were more popular, many laptops were equipped with CD-ROMs. At present, with the diversification of people's lives, portability has become more and more important. Therefore, some notebook computers will not install optical drives, such as our common ultrabooks. So what is the use of optical drives for notebooks?
The full name of the CD-ROM is called the CD-ROM. The so-called CD-ROM is a hardware component that uses it to read the content of the CD-ROM. Now the progress of science and technology has brought us many different electronic storage devices, mobile hard disks, U disks, memory cards, etc., which play a very important role in our data transmission work. In the past, the optical discs we often used were portable, stable and cheap, so we have not eliminated optical discs until today. Instead, read CD-ROMs as a very important job for a computer. Therefore, today's optical discs and optical drives have been differentiated into different types. They differ in read or write speed.
With the continuous increase of the amount of data in modern society and the increasing number of data types, many types of computer optical drives have also been developed. Generally speaking, the optical drive of the computer is mainly divided into five types: CD-ROM drive, DVD-ROM drive (DVD-ROM), combo (COMBO) and burner.
There are fewer and fewer optical discs on the market. On the one hand, the capacity of optical discs is limited, and electromechanical conversion is required for storage and reading, which is prone to failure over time. The disc material itself is also more prone to wear and tear. On the other hand, there are now many U disks, mobile hard disks and other devices that can replace the CD-ROM, and many contents stored on the CD-ROM can also be shared through the network. All optical discs are gradually being replaced by networks and other hardware.
Laptops are more portable than PCs, and are small.So how heavy is a laptop? It depends on the size and internal configuration of the laptop.

Portable personal computer, usually weighing 1-3 kg.
The main difference between a notebook and a PC is that it is easy to carry, and has different requirements for the motherboard, CPU, memory, graphics card, and hard disk capacity. Although the fuselage of the notebook is very light, there is absolutely no doubt about its applicability. In daily operation and basic business, entertainment, and computing operations, the notebook computer is fully capable. Today's notebook computers are differentiated into different trends according to their uses. Netbooks tend to be used for daily office work and movies; business notebooks tend to be stable and low power consumption for longer battery life; home notebooks have good performance and high cost performance.
