The computer laptop keeps the screen black when it doesn t turn on

The laptop won't turn on and the screen goes black.

1. Black screen caused by software. 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 of the laptop caused by the software. If the black screen is caused by software, take the Windows system as an example, you can restart the machine, press the F8 key several times when booting up, and bring up the system's boot options menu.

Once the System Boot Options menu comes out, select Enter Safe Mode. If you can enter the safe mode normally, you can delete the software or driver installed before the black screen in the safe mode. Then restart the machine and see if the laptop can fix the black screen issue.

2. The laptop screen is blacked out due to hardware. Hardware-induced black screen for the following reasons:

1) The cause of static electricity, sometimes static electricity will cause the circuit of the notebook motherboard to be abnormal, resulting in no reaction on the screen after the power is turned on. You can try to turn off the battery and power of the laptop, and then press the power start of the laptop several times to let the machine release the static electricity. Then connect the power supply, turn it on, and see if it can solve the fault.

2) The memory is loose or the memory has a hardware failure. There are several major components of a laptop computer, including the CPU, motherboard, memory, and graphics card. These parts are indispensable, as long as one of them has a problem, it will cause the laptop to not function properly, the most common is that the boot does not respond.

In general, the probability of CPU and motherboard failure is relatively small, and it is more common for the laptop to fail to boot due to loose memory. At this time, first remove the battery and power supply of the notebook, if it is not difficult to remove the computer, you can open the back cover of the notebook by yourself and reinsert the memory. After plugging in the memory, power it on again, start the machine, and see if you can solve the fault.

Dear users, hello.

The first reason: the adaptation power supply of the notebook is one of the main reasons for the black screen of the computer, because there is no power input, the host and the LCD screen can not work, so the black screen, the solution: replace the adapter of the notebook, it is OK

The second reason: the memory and graphics card are oxidized, resulting in poor contact with the memory slot or graphics card slot, resulting in a black screen, it has a black screen probability of 80%, the treatment method: is to turn off the power, open the compartment, dial out the memory, and the graphics card, align the memory and the graphics card gold finger (that is, where there is a copper sheet) with an eraser back and forth at least 6 times, blow the ash, and then plug it back, boot is generally OK.

The third reason: that is, the graphics card's video memory is soldered, the performance of the main chip is reduced, the graphics card BIOS is confused, and the control power supply IC is problematic, which will cause the graphics card to fail to work normally, that is, the graphics card is broken, and the graphics card is broken, and the screen will naturally be black.

The fourth reason: there is a problem with the boot circuit of the motherboard, resulting in a failure to turn on, a black screen, a problem with the main power supply of the CPU, and a problem with the CPU, and a problem with the computer, a black screen, etc., In short, the components on the motherboard are faulty, many will not be able to turn on, black screen, many notebooks encounter this situation, the solution, the fifth reason is that the screen line of the notebook is broken or the contact is poor, resulting in no image signal transmitted to the screen display, That is, the black screen, the solution: ask the person in the Weili notebook to plug in the screen cable again, or replace the screen cable.

You can buy a telecom mobile phone in the Anhui Telecom online business hall, and the network hall will handle the contract machine to give a high phone bill, you can buy the machine at 0 yuan, which is very discounted, and at present, a number of brands of 4G models are fully listed!

2.Press the F2 button when the computer is turned on to enter the BIOS interface to check whether it is displayed normally. (1) If the BIOS screen is black, it may be a hardware problem, please bring the machine to the ASUS service center for testing.

2) If the BIOS interface is displayed normally, please try to press the F9 button in the BIOS interface to restore the default value, then press F10 to save and exit, and restart the computer.

3.Please check if you have installed any memory or other hardware. If so, please remove the additional memory and other hardware before turning on the computer to confirm.

4.Remove the transformer and press the power button for 40 seconds (hold and don't let go).

The true black screen is mostly a problem with the graphics card chip,If it is the chip of the NVIDA graphics card door, including the integrated graphics card, if you want to completely solve it, you must change to a new and improved version of the graphics card chip,Otherwise, it must be **,If it is not the chip of the graphics card door, such as ATI, you only need to add welding。

Summary. Dear Hello: Glad to have your question; Help you find out:

The reasons why it can't be turned on are as follows:1It may be due to the power adapter of the notebook being damaged and not charging normally, or the current battery is dead, you can try to replace the power adapter and then fully charge the battery. 2.

It is also possible that the memory slot in the notebook is not in good contact, resulting in a black screen that cannot be turned on; You first cut off the power supply, open the back cover of the computer, then take out the memory, use the eraser to align the gold finger part of the memory, wipe it back and forth a few times, blow the ash, and then plug it back, cover the back cover, and generally it can be turned on normally; 3.The video memory of the notebook graphics card is soldered, which can only be repaired by after-sales personnel; It may also be that the boot circuit of the notebook motherboard is faulty, such as clock, reset, power supply, MOS tube, etc., which may cause failure to turn on, black screen, and IO problems, which can only be sent to the after-sales service or repair shop The repairer hopes that mine can help you I wish you a happy life and all the best!

The laptop won't turn on and the screen keeps black.

Can you add, I don't quite understand it.

The black screen of the laptop may be caused by the following reasons: Power problems: The battery is low, the power adapter is faulty, or the power supply is unstable, etc., which may cause the computer to not turn on properly.

Hardware failure: Hardware failures such as memory, hard disks, and graphics cards may cause the computer to fail to boot properly. Software glitches:

A malfunctioning operating system, incompatible drivers, or software issues such as virus infections can cause your computer to not boot properly. Workaround: Check the power supply:

Make sure the battery is sufficient or plug in the power adapter, check whether the power adapter is working properly, and confirm that the power supply is stable. Check the hardware: Check whether the memory, hard disk, graphics card, and other hardware are working properly, and try to remove the memory, hard disk, and other hardware and insert it again.

Enter Safe Mode: Press the F8 or F12 key during the boot process to enter safe mode, try to repair or restore the system, or uninstall software failures such as drivers. External monitors are like cavities:

The laptop may not boot properly, but the external monitor can display normally, so you need to check whether the laptop screen is working properly, or replace the screen. Factory reset: Try factory resetting your computer, erase all data, and reinstall the operating system and software.

If none of the above methods can solve the problem, it may be caused by hardware failure, it is recommended that Rubber Attack contact a professional computer repair personnel for inspection and repair.
