What should I do if the laptop boot display shows no signal and black screen?

You can remove the memory first, erase the gold finger with an eraser, and then put it back on to try, if it doesn't work, you have to send it for repair.

Hope, thank you.

There is no display on the boot screen of the laptop, it must be a hardware problem, including the display screen itself or the fault of the screen cable, if the display screen can display a pattern without signal, then the fault of the display screen can be basically eliminated, due to the small internal space of the notebook, it is more troublesome to disassemble and check the replacement hardware, and basically can only plug and insert the replacement memory module, so if the problem cannot be solved after replacing the memory module, it can basically only find a professional to detect and repair.

That means that the system is broken, then there is no signal, then you reinstall the system.

There are many reasons for this, but it can be as simple as restarting your computer and seeing if the glitch goes away? If the fault persists, it may be a virus or system problem, and the only way to restore the system or reinstall the system is to restore the system.

After the laptop is turned on, the screen will show that there is no signal, if it is a black screen, it is a problem with the circuit board, so the best thing to do is to restart your computer.

1.The power adapter of the laptop is damaged, the BAI cannot be powered, or the battery of the laptop is dead, and it will not turn on from the surface to the black screen. Solution: Replace the power adapter or fully charge the battery.

2.That is, the screen cable of the notebook is broken or the contact is poor, resulting in no image signal transmitted to the screen display, that is, a black screen, the solution: let the person who repairs the notebook replug the screen cable, or replace the screen cable.

2. Check the sleep switch signal again, the positive code is in the normal state of the sleep signal to be high level (professionals can detect it), and some machines have a sleep control switch, and the switch should be bounced up.

3. When the whole machine is powered off, open the back cover, unplug the memory and wipe it, and then install it back to try it.

4. Take off the radiator and reinstall the CPU, some models have an independent graphics cardboard, you can take off the graphics card board and wipe the gold finger and then put it back to try.

5. It may be due to the damage of a peripheral, which may cause the boot screen to be black, you can unplug each peripheral one by one and boot it for testing.

Hardware causes a black screen situation:

1. Whether the laptop battery is out of power.

2. The cable contact of the display is poor.

3. Poor contact of the graphics card.

4. Poor memory contact.

5. There is a problem with the power supply.

6. The display screen is broken.

There has been no signal, indicating that the host hardware is faulty! Check whether the hardware is normal one by one, the new computer is generally fully removed from the back cover, the old computer can be dismantled part of the good source, see the memory hard disk or something, reseat the memory and hard disk and then reboot it to see if it returns to normal, if it still doesn't work, you need to check other major hardware.

The pen mold Chang Ji computer boots up on the black screen,Maybe there is a hardware problem with Hehe,Check the power adapter and battery first,Call the code pie,Re-insert the memory module or replace the memory module to try,No, go to the notebook manufacturer after-sales service to check the quality of the motherboard and other hardware。

It means that the host does not start normally, but it is difficult for individuals to solve it, it is recommended to contact the official after-sales service center for after-sales help to check and deal with it.

Summary. It is not a very rare problem that the computer boot display screen shows no signal and black screen, and it also bothers many users who are unable to continue to use the computer, in fact, many times it is caused by computer hardware problems. 1. First of all, check whether the signal line of the computer host display and the host interface position are loose, and you can plug and unplug it.

2. Put the signal cable of the display to see if the line of the signal cable interface is damaged, and replace the cable if it doesn't work. 3. Check whether the motherboard monitor interface behind your host is playing well, and see if the pins of the interface are damaged. 4. Open the lid of the computer host to see if the interface of each host is in good condition and whether there is any damage.

5. If there is a beep alarm on the computer, remove the memory module to see if there is any trace of burning.

Trouble to give a thumbs up.

Hello, I am happy to answer for you. Good morning, dear! Glad to serve you, the answer here is:

1. Data cable connection; The data cable connecting the monitor and the computer host is loose and in poor contact, and when the computer does not have a signal, you should see whether the display data cable is connected well. 2. Independent display; The data cable should be connected to the ** output interface of the graphics card, not the ** signal output interface of the motherboard.
