What is the cause of the sudden black screen of ASUS notebook when it is turned on?

1. Remove the battery, all external equipment and external power supply, let it stand for 10 minutes, then plug in the external power supply separately, press the power button to see if it can be turned on normally and enter the system;

2. If the fault is still after the operation according to 1. In the case of power off, connect the external monitor through the VGA cable or HDMI cable, and then turn it on again to see if the external monitor can display the boot screen normally.

If there is an external display screen, you can enter the system normally. The initial judgment may be that there is a problem with the screen cable or screen.

3. Check whether the machine has a reset hole, such as UX30, you can refer to the figure below. You can use a paper clip to hold down for more than 10 seconds before turning it on again;

4. If the fault is still after the above attempts. You can contact the ASUS service center for further testing of the hardware.

The sudden black screen of a laptop when it is turned on is usually caused by a hardware failure. It may be caused by problems with the processor, graphics card, memory, etc. You can plug and unplug these hardware first, sometimes the above problems will occur due to poor contact.

That's a problem with the motherboard or memory.

For ASUS laptops, you need to check if the power adapter is connected or check if the screen is unusually black due to system problems.

1. First of all, I have to mention some very common but potentially ignored situations, such as the power plug of the monitor is loose, not energized, or the VGA interface is not in good contact, or the monitor switch has some minor faults and is not pressed. If everything is confirmed, we are sure that it is a hardware failure.

2. Heat dissipation problem: After the computer is turned on, it enters the system normally, and after running for a period of time (or a short period of normal use), the screen suddenly goes black, which is likely to be caused by heat dissipation, the normal temperature is 30-50 degrees, under normal circumstances, any part exceeding 50 degrees will cause the motherboard to be protected, so the computer will automatically shut down and restart. The solution is also very simple, add thermal paste, or replace the radiator.

3. Graphics card or monitor problem: These two kinds of equipment account for a large proportion of the black screen failure of the computer boot, usually use the substitution method, use a different monitor, such as normal use, indicating that the original display is broken. If you change a monitor or a black screen, consider the host problem, usually for example, it is easy to think of the graphics card problem, and the graphics card can also be replaced, such as the normal display, saying that the card is obviously faulty.

4. Power supply problem: everyone always works the CPU and memory when configuring the machine, and the power supply is always deducted, but the power supply is to provide power for all components, if it is faulty, the host will send out a "drop" alarm. And the display is not lit, and occasionally there is no sound, and it is also a power supply problem after investigation.

5. Motherboard problem: The main reason is that the CMOS is set incorrectly, the first initialized graphics card is set to PCI or the onboard AGP graphics card, and the display is not connected to the corresponding position, and the host starts normally, but the display does not light up.

1. The reason why the laptop boots up with a black screen.

There are many reasons for a laptop black screen, and the common reasons for a black screen are:

1. Poor contact of display data line BAI;

2. Poor contact of the graphics card or;

3. Poor CPU contact and overheating;

4. Poor contact of memory modules;

5. Poor power supply performance;

6. The machine is infected with CIH virus, and the BIOS is destructively refreshed;

2. How to fix the black screen of the laptop.

1. The boot display screen is black, only the indicator light is on, and the host does not have any reaction. I can't feel the fan spinning behind my hand behind the main unit. None of the voltages are measured. Remove it and find that the power adjustment tube is broken, and replace it with normal.

2. The power supply and CPU fan are normal, but the screen has no reflection, and there is no self-test sound. This machine adopts SLOT1 structure, and the CPU is easy to contact poorly, so it is sent to the after-sales service for inspection and maintenance.

3. Do not self-check when you turn on the machine, and check that the power supply is normal. Using the minimal system method, the machine can start normally when the optical drive is unplugged. Then install the fault recurrence. It means that there is a problem with the optical drive, and the machine cannot be started. It should be sent to the after-sales service immediately for disposal.

Summary. 1. Check whether the notebook is in a sleeping or dormant stateWhen the notebook is in a sleeping or dormant state, and then the notebook is in a state of fake death and black screen, it will be mistaken for a black screen. So I want to check if it's in both states.

Sleep or hibernate is an energy-saving feature that turns off the display, and if the laptop is turned on but used for a while or enters a state that shows low battery power, the system may start sleep and hibernate mode. You can change the setting of sleep or hibernation, and the method of setting:

What is the reason why the ASUS computer turns on but the screen is black.

Hardware reasons: 1. Poor contact of display data cable; 2. Poor contact of the graphics card or; 3. Poor CPU contact and overheating; 4. Poor contact of memory modules;

Solution: 1. Reinsert the data cable 2. Unplug the memory, clear the gold finger, and insert it normally. 3. The CPU is easy to contact poorly, dissipate heat in time, and reinstall normally. 4. Replug the display signal cable behind it and replug it in.

You can turn on the phone, but you can't see the lock screen, you need to press the power button twice more to see the lock screen.

Hello, please describe your current problem in detail.

It's a black screen after booting, and you have to press the power button twice to see the lock screen and then enter the computer.

1. Check whether the notebook is in a sleeping or dormant stateWhen the notebook is in a sleeping or dormant state, and then the notebook is in a state of fake death and black screen, it will be mistaken for a black screen. So I want to check if it's in both states. Sleep or hibernate is an energy-saving feature that turns off the display, and if the laptop is turned on but used for a while or enters a state that shows low battery power, the system may start sleep and hibernate mode.

You can change the setting of sleep or hibernation, and the method of setting:

If the notebook is asleep, simply press any key on the notebook to restart it.

Notebook hibernation is when the notebook is at rest. If you don't want the notebook to be asleep, you can make relevant settings, take win7 system as an example, right-click on the desktop, select "Personalization", then select "Screen Saver", click "Change Power Options", "Change Computer Sleep Time", make relevant settings, you can choose "Never".

Screen issues. 1. The boot screen is black, but there is a sound to determine that it enters the system normally, try to connect the external monitor to see if the graphics card output is normal, if the external monitor can be turned on and displayed normally, it means that it is a problem with the notebook LCD screen or cable.

2. It may be caused by poor contact, and it is recommended to restart the notebook. If it still can't solve the problem, it means that the monitor is broken, and it is recommended to go to a repair shop to repair it.

Graphics card motherboard issues.

1. Like the first case, the boot screen is black, but there is sound entering the system, and the external monitor is still abnormal, which may be a problem with the graphics card or motherboard.

2. You can disassemble the shell, make the interface connector between the monitor and the motherboard tighter, remove the dusty places, and then install the parts of the notebook one by one.

3. If it can't be solved, it is recommended to restart the computer, keep pressing F8, enter the safe mode, and then disinfect and repair the missing system files. Reboot it again, and maybe it will be solved.

System issues. 1. The boot screen caused by the system, the screen is black in this case, there will be BIOS interface logo, and the cursor will flash in the upper left corner of the screen, even if there is no cursor, the screen will be brighter than if it is not powered on.

2. It is recommended to reboot the computer, enter the BIOS, and then select the U disk to boot and enter the PE system. After entering, the system problem will be repaired and anti-virus and other operations.

Low battery issues.

If you forget to shut down the computer after using the computer for a long time, the computer screen will go black after that. Try plugging it in and maybe the problem will be solved.
