The computer and notebook display is not lit but the console is turned on

Nowadays, many friends will use laptops to work for the convenience of their work, but there will be problems in the process of using the computer, what is the problem that the laptop display screen is not lit but the host has been turned on?

1. The host of the laptop has been turned on but the display screen is not lit, if the cooling fan port of the laptop has wind, and the number of hidden flush indicators can also be displayed normally, it is likely that the internal wiring of the laptop is faulty, or the internal hardware is faulty, in this case, it is recommended to send it to a professional computer repair shop for repair.

2. When the memory module and graphics card of the notebook are not used for a long time, there may be oxidation, which will lead to poor contact between the slot of the memory module and the slot of the graphics card, resulting in the situation that the display cannot be displayed.

3. At this time, you can pull out the graphics card and memory module, gently wipe it clean with an eraser and blow off the ash in the slot, and then reinsert the graphics card and memory module.

4. When the video flash memory of the graphics card is soldered virtually, the performance of the main chip will be reduced, the BIOS of the graphics card will be disordered, the control power supply will be insufficient, etc., and the display will not be able to display normally.

If the laptop host is turned on but the display screen does not light up, it may be caused by a line failure or hardware failure, in which case it is recommended to send it to a computer repair point for repair. It may also be because you have not used the computer for a long time, and the memory module and graphics card have oxidized, you can remove the graphics card and memory module with an eraser and wipe them clean, and then put them back in their original position.

Computer model: Lenovo Tianyi 510S

System version: Windows 10

1. Check whether the indicator of the display is normal, and check the power cord and switch. 2. Check the connection cable between the computer and the monitor, you can try to disconnect the cable, and then reconnect it. 3. Check whether the corresponding indicator light of the numlock key on the keyboard is normal, if the indicator light is normal to light up, it is a problem with the display, and if it is not lit, it is a problem with the computer case.

4. If there is no signal on the monitor, you can try to clean the graphics card, memory module and card slot in the shutdown state, and plug it in again.

5. When the main computer is turned off, turn off the power, and try to press and hold the power button for about ten seconds to release the static electricity in the case and restart it.

If none of the above methods can solve the problem that the computer screen is not lit but the host has been turned on, you can send the computer to a professional maintenance point for repair.

A computer monitor is also commonly referred to as a computer monitor or computer screen. It is the most important part of a computer besides the CPU, motherboard, memory, power supply, keyboard, and mouse. There is no unified concept of computer monitor, but the understanding of it is mostly the same, as the name suggests, it should be a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye.

Summary. It may be due to the fact that the computer itself does not start normally, or the power of the monitor is not turned on, check whether it is caused by the failure of the ** cable, and try to change it; It is also possible that the monitor is damaged, which can only be repaired or replaced. Here's a closer look:

1. Check whether the power supply of the display is turned on, or whether the power cord is connected normally; Then check whether the connection between the ** cable of the host and the top of the display is normal; 2. Check whether the host is turned on normally, whether the status light on the front panel of the chassis is turned on, and whether the indicator light on the keyboard is turned on. 3. Change a ** signal line, or change a display to eliminate whether it is a monitor or a ** line; 4. If the host cannot be turned on normally, after ruling out the power supply problem, try to check whether the memory is plugged in tightly, generally after the chassis is moved, the memory may become loose and cause a boot failure, or blow the dust near the memory slot first, and then wipe the gold finger of the memory module with an eraser after cleaning it up;

I'm still a little confused, can you be more detailed?

Summary. Hello dear, I'm glad to answer for you There is a sound on the host when you turn it on, and the computer can't display it (black screen) Solution: 1) The monitor is powered off, or the monitor data cable is in poor contact. In addition, the computer has been used for a long time, and the power cord of the monitor is easy to oxidize and break; (2) There is no power supply to the motherboard; (3) Poor contact or damage to the graphics card; (4) Poor CPU contact; (5) Poor contact of memory modules; (6) The machine is infected with CIH virus, and the BIOS is destructively refreshed; (7) Check the plugging and unplugging, if necessary, you can use a rubber to remove the oxide film on the gold finger; (8) If the floppy drive has a floppy disk, many times it will cause the computer to start or restart, the computer will have a black screen, and it will not be able to enter the system.

To avoid such situations, it is also possible to cancel the floppy disk boot item in the BIOS.

The boot sound is there.

But what to do with a black screen.

<> solution to the computer display screen is not lit but the host has been turned on: 1. Check whether the data connection cable is loose or damaged, and tighten it if it is loose.

2. Find a new data cable to test, or start testing and repairing from the graphics card and motherboard. Graphics card problems are generally due to poor characteristics of the graphics card's main control chip, poor contact with the graphics card slot, or too much dust in the graphics card slot.

This answer is applicable to most brands of computer models such as Dell, Apple, Asus, etc.
