What should I do if my laptop keeps having a white screen when I turn it on? 5

The laptop has a white screen when it is turned on, which is caused by the LCD panel drive circuit problem, the LCD panel power supply circuit problem, the screen wire contact poorly, and the motherboard control circuit problem.

Since the LCD screen is white after turning on, it means that the backlight and high-voltage generation circuit are working normally, but the LCD panel does not get the driving signal. If the screen disappears after the laptop is turned off, and then the screen is white again, it may be caused by a problem with the power strip.

1 Wire Problem.

There will be such a situation when the cable is loose, and the connection is not normal. Sometimes the screen will be flickering, blurry, and white!

2 Power issues.

The power tube is aging and gray, which will cause the power input to be unstable! For example: When the machine is turned on, the current is normal. But the current it gives has already been exceeded. Directly causes screen display problems at startup.

It is recommended to send it for repair.

It may be that there is a problem with the display, you can connect an external monitor to see if it can be displayed, if not, it is the system, the problem. It may also be a voltage problem, try to connect the charger to turn it on, if it still can't be solved, it is recommended to contact professional after-sales service for maintenance.

1. If the monitor, power supply and CPU work for too long, it will cause a crash. Dusting, oiling, or fan replacement will be performed. A temporary fan will be added to the main cabinet of the desktop computer to assist in heat dissipation, and a cooling pad will be added in the book.

2. The machine has too much dust and poor contact. Clean the chassis and plug all connections firmly in.

3. If the memory module is loose, please pull out the memory, clean the slot, clean the memory finger, and then insert it tightly. If there is a problem with the quality of the memory module, replace the problematic memory and increase the virtual memory value.

Stuck in the boot interface, it means that the hardware has not passed the BIOS test, and there is no half-dime relationship with the system, it can only be a hardware failure. You can enter the logo interface, at least it means that the CPU-+ motherboard + graphics card is good, in this case, the computer will be stuck, the memory is bad, and the gold finger is rusted (generally plug and unplug the memory and wipe it).

Press f8 to do not move to the advanced option appears in the let go, select "the latest correct configuration" enter to repair, it is not possible to press f8 to enter the safe mode to restore the system or reinstall the system (if you can enter the safe mode, it means that you have installed inappropriate things, uninstall all the inappropriate things before the accident, or restore the system or reinstall).

Restart the computer, press F8, and the selection menu will appear. Select the last correct configuration, try the safe mode, and if you can enter the safe mode, you can uninstall the recently installed software or drivers. If this is still the case, the system will have to be redone.

It's possible that the software is incompatible, but this is rarely the case. After confirming that the computer has been normal before, the computer blue screen failure often occurs after installing the software, it is recommended to uninstall the software to try.

Generally, you will choose to start Windows normally, but this prompt will appear the next time you turn on the computer. The reason for the Windows error recovery prompt is usually caused by the recently installed hardware or software.

At this time, you can take your laptop to the place where the computer is sold, or go to a professional who knows how to repair the computer, they know better and can help you fix it.

In this case, it is best to go to the repair department to repair it, let a professional person take a look at it, check it, it is likely that the notebook is faulty.

The computer has a white screen, it is recommended to solve it from the following aspects: 1. If the monitor, power supply and CPU work for too long, it will cause a crash. Dusting, oiling, or fan replacement will be performed.

Go to the BIOS first to confirm if there is a fault.

ASUS notebooks.

Enter the BIOS method: boot the laptop on power.

Once you see the ASUS screen, press F2 to type in the BIOS menu.

If a white screen appears before entering the system, it may be a system problem, and it is recommended to go to safe mode.

Resolved.

Taking win10 laptop as an example, the following is a brief introduction to the specific causes and solutions of the white screen after booting:

1. Graphics card failure, this may be a problem with the computer graphics card or a problem with the computer driver, it is recommended to detect the problem with relevant software. 2. Connection failure, there is a problem with the data connection cable between the graphics card and the display, this problem is more common on laptops, whether the connection is open or short-circuited, it will cause the display signal to not be able to display normally. It is recommended to replace the data cable or ask a professional to solve it above.

3. If the display itself is faulty, in this case, it means that the main chip of the control screen has been damaged, in this case, it is recommended to go to the local maintenance point for inspection and repair.

In order to avoid this problem again in the future, in the process of using the computer, you should try to avoid turning the LCD screen and the host together, when the computer screen has abnormal flashing, you should pay attention to observe, do not easily move, be sure to find a professional maintenance point to detect or ask professionals to come to repair.

Go to the BIOS first to confirm if there is a fault.

How to enter the BIOS on the ASUS notebook: Turn on the laptop and press F2 to type in the BIOS menu when you see the ASUS screen.

If a white screen appears before entering the system, it may be a system problem, and it is recommended to solve it in safe mode.

After the laptop is turned on, the screen is white, and you can restart the computer to see if the problem can be solved.

If it can be resolved, it means that a certain system file is back to normal booting, and there is no problem.

If it can't be solved, it is still a white screen, you can use the manager to see what system files are not started, and solve it by manual startup.

Causes and solutions for the white screen at boot:

1. The screen cable is damaged or the contact is not good.

2. The screen itself is damaged.

3. There is a problem with the motherboard supplying power to the screen, and it is also possible that the power supply IC is faulty.

4. The screen cable of the notebook is not in good contact and is sent for repair for testing.

5. Caused by the virtual soldering of the graphics card chip, the virtual soldering of the graphics card refers to the poor contact between the BGA solder joint of the graphics card chip and the motherboard, which is generally caused by the high temperature of the graphics card and can only be sent for repair and testing.

6. If the heat dissipation device fails, it will affect the motherboard, and there will be problems with the motherboard, so you can go to the maintenance center to deal with it.

The white screen phenomenon is usually a problem with the screen.

The most common cause of white screen is that the cable between the LCD screen and the motherboard is loose, and poor contact will cause a white screen. If you have a certain amount of hands-on ability, you can disassemble the book by yourself, reinsert the wire and fix it, which can generally be solved.

If it is not a cable problem, it is more difficult for our individual users to deal with, and it is generally recommended to send it to a professional repair shop for inspection and maintenance.

You can troubleshoot by following these steps:

1. If there is a connection problem with the monitor or screen, you can try to adjust the screen angle to see if it can be displayed normally.

2. Try to update the display adapter driver to the official latest.

3. If the latest system update or installation is caused, you can try to uninstall the latest installation.

People who often use computers understand the meaning of this "white screen", but there are also a few people who use computers who do not know enough about this white screen.

Is it a quality problem with the screen or a damaged graphics card?

Will it occur if the LCD screen is not in good contact with the motherboard cable frequently?

Why do some laptops occasionally have white screens?

How can you determine the meaning of a white screen?

There are several common causes of a white screen at boot.

If the screen cable is damaged or not in good contact, the screen itself is damaged, the motherboard has a problem supplying power to the screen, or the graphics card chip is caused by virtual soldering, it is recommended to send it for repair and testing.

The screen cable is damaged or not in good contact:

The keyboard can be removed if the screen cable of the notebook is not in good contact, and the cable is generally hidden above the plane where the keyboard is located, and the cable can be repressed through the space removed from the keyboard.

The screen itself is damaged, or the motherboard is powering the screen

This is usually a problem with the power cable from the motherboard to the display, or a direct short circuit on the screen.

Graphics card chip virtual soldering:

Graphics card virtual soldering refers to the poor contact between the BGA solder joints of the graphics card chip and the motherboard, which is generally caused by the high temperature of the graphics card.

If you want to determine whether this white screen is a broken screen or a problem with the graphics card chip, we have some tips that we can share with you.

The first one to listen to!

When we boot up, although the screen is a piece of white flowers, we can wait a little to see if we can hear the sound of booting into windows, if there is a sound, then it can be basically determined, the problem is on the screen.

The second one is to take a look!

Most people usually have more than one computer at home, for example, some people have a desktop computer at home, we can connect the laptop to the desktop computer monitor to see if there is an image, so we can also judge whether the laptop graphics card is damaged!

If the display of the monitor and the display of the laptop screen are both white, then the possibility of damage to the graphics card is higher.

The third rub it.

If we can see the normal picture after connecting the external monitor, or hear the sound of booting into Windows, then the next point is particularly important, because this is the most important link to determine whether your screen is damaged.

As we all know, there is a layer of hub between our screen and the motherboard, that is, a long cable, if we encounter the above situation, we can disassemble the machine and the screen, check whether the cable is loose, or simply plug it back in.

Some computers will successfully display the picture after such replugging and unplugging, so it can be determined that the white screen problem is caused by loose cables. If this problem is still not solved, then it needs to be sent to a professional maintenance and testing center for testing and maintenance.
