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.

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.

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

Dear, first of all, we have to see if the hard disk indicator lights up when the screen is black, and you can also listen carefully to see if there is a boot into the system**, in any case, it means that the hard disk has worked. 2.When the above situation occurs, we can carefully observe the screen in a well-lit place, or illuminate the screen with a strong flashlight, if the picture can be seen faintly, it means that there is a problem with the backlight of the display.

3.If you can't see the screen display, you can connect an external monitor, press the fn and external display buttons on the notebook keyboard to see if it can be displayed, if you can, it may be that the backlight is damaged. 4.

If the hard drive light is not on, and the external monitor is not displayed, we can remove the laptop battery, open the back cover, first pull out the memory module, wipe the gold finger, and replace one conditionally, to see if it works.

It may also be that there is a problem with the graphics card driver,F8Enter the safe mode,Uninstall the graphics card driver after entering the system,Then restart it will boot normally,After booting** driver wizard or 360 driver master,Just drive the graphics card again。

Questions. As soon as I signed up for Microsoft, the screen went black.

Pro, if it is a first-time installation system, it is generally incompatible with the system and hardware. Otherwise, there is a higher chance of poisoning or loss of files.

Dear, it is recommended to reinstall the system and try it.

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:

Shanghai notebook repair center 400-669-99651, display data cable poor contact;

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 a 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.

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.

Here's how to fix it:Reason 1: Battery, power supply problems1, check all cables (including power plugs) to ensure that all devices are properly and tightly connected together.

2. Check whether the laptop has power (although most people will not make such a low-level mistake), because the notebook has a built-in battery, so it can be used without plugging in the power supply, of course, the time is limited, when the built-in battery is used up and not charged, it will cause the notebook to fail to turn on, at this time we just need to plug in the power to charge.

Reason 2: It may be caused by a virus infection, press and hold F8 to enter the advanced options page, select "Latest Correct Configuration", and then press Enter. After entering the system, run the anti-virus software, check and kill the virus, if there is a virus, restart the computer after the anti-virus, if it is not normal, it may be caused by the incompatibility of the device driver and the program, delete the graphics card, network card and other drivers, delete the driver and restart, if not, then rule out this reason.

Reason 3: Hardware problem: Disassemble the notebook to check whether the hardware is loose, generally the hardware is not plugged in well, there will be an alarm sound, the long sound continues to ring means that the memory module is not plugged in tightly, one long and one short means that the memory or motherboard has a problem, one long and two short means that the graphics card is wrong. If there is too much dust inside the notebook, it is best to clean it up first.

In addition, pay attention to whether it is caused by the new hardware, if it is normal before the replacement of the hardware, and it is not normal after the replacement, then check whether it is compatible. If it doesn't start at this time, it's best to send it for repair, and a professional will check whether there is a problem with your hardware one by one. Reason 4:

Display ProblemsIf the power supply** is working, but the screen is still pitch black, try connecting another monitor to your computer (you can borrow one if necessary) to make sure it's not a monitor issue.
