The laptop screen goes black after the logo is turned on, and it takes a few minutes to enter the de

There are several reasons that can cause this situation, unplug the graphics card, wipe the gold finger on, and try to update the graphics card driver.

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 caused by the software. Here's how to fix it:

1. Press and hold "Ctrl+Shift+.""Launch Windows Task Manager.

2. Click"Applications"。

3. In"Applications"Options, click in the lower-right corner"New task (n)."。

4. Eject"Create a new task"window, Enter"explorer"。

5. Click "OK" or press "Enter" directly to restart the computer.

Summary. 1. Unplug all external devices, such as mouse and keyboard, external screen, etc., unplug the external power supply and use the battery to turn on, and confirm whether the hard disk indicator flashes during the boot process and whether it is turned on**.

2. Repeat the above operation, this time plug in the external power supply, remove the battery and boot the test. The analysis of the test results of the above two items is that if any two of them are in the same state of boot black screen and no boot sound, it may be caused by a motherboard failure. If there is a boot **, it means that you can enter the system, and the situation may be a failure of the screen itself, a data transmission problem with the screen cable, such as only one of the above two boots** or a successful boot, it means that it is a problem with the power adapter or battery.

3. 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. Hope it helps.

When the computer is turned on, the logo screen goes black.

It's the Rescuer Y7000 After the last forced shutdown, this time it was turned on to enter the logo loading interface, and then it entered the black screen, the screen has been black, the fan rotates normally, and the keyboard light is normal.

The analysis of the test results of the above two items is that if any two of them are in the same state of boot black screen and no boot sound, it may be caused by a motherboard failure.

If there is a boot **, it means that you can enter the system, and the situation may be a failure of the screen itself, a data transmission problem with the screen cable, such as only one of the above two boots** or a successful boot, it means that it is a problem with the power adapter or battery. 3.

Summary. 1. First of all, let's check whether the power cable is normal, and then check whether the display is damaged, the detection method is to turn off the computer, only turn on the monitor, and see if the display has a signal, no signal means that the display is fine. 2. Incompatible graphics card drivers will also cause a black screen, we first restart the computer, and then keep clicking the F8 key to enter safe mode.

Enter Safe Mode, then check for viruses and uninstall recently installed programs and software. 3. If you can't enter the safe mode or the screen is still black after entering, let's decisively reinstall the system. 4. In fact, there may be a problem with the hardware, the most hardware problem is the memory module, disassemble the machine and pull out the memory module to see if there is any oxidation, wipe the gold finger with an eraser or replace the memory module and insert it back.

Extended Information: Software (Chinese mainland and Hong Kong terminology, called software in Taiwan) is a collection of computer data and instructions that organize the limbs in a specific order.

Generally speaking, software is divided into system software, software for use and middleware in between. Software does not only include computer programs that can be run on a computer (in this case, a computer in a broad sense), but also documents related to these computer programs are generally considered to be part of the software. To put it simply, software is a collection of programs and documents.

In addition, it also refers to the management system, ideological ideology, ideological and political consciousness, laws and regulations in the social structure.

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, restart after removing the driver, if it doesn't work, 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.
