Lenovo monitor black screen, what to do if the display screen is black after Lenovo computer is turn

Dear Lenovo users, for your question, it is recommended that you update or reinstall the graphics card driver.

Hello friends:

There are seven main reasons for the black screen of Lenovo computer boot: (the following includes the method of processing).

The first reason: it is possible that the connection between your host and the monitor is not well connected (especially the interface is not plugged in), and there may be a problem with this connection data cable, so it will not be displayed and the screen will be black, so you have to reconnect the data cable, or replace the data cable.

The second reason: due to the memory or graphics card's gold finger is oxidized, resulting in poor contact between the memory and the memory slot, the graphics card and the graphics card slot are in poor contact, and the lead to the inability to boot, it will naturally be black, the processing method: turn off the power, open the chassis, remove the memory and the independent graphics card, use the eraser to align the gold finger of the memory (that is, the part with the copper sheet) on both sides of the wipe a few times, and then insert them back, the independent graphics card is also processed in the same way, and then the chassis is installed, plugged in the wire, generally treated like this, OK, (take the memory diagram as follows:.)

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 disordered, 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 computer will not be able to display, and the screen will be black when it is turned on.

The fourth reason: the problem of power supply, when the filter capacitor of the power supply bulges, leakage, there will be leakage, when the power supply is insufficient after starting, there is not enough voltage and current for the host to start, the power supply self-protection circuit starts self-protection, power off, no electricity, it is naturally a black screen, the treatment method, which can only replace the power supply.

The fifth reason: if the host is normal, the connection line is also normal, or the black screen, which is the problem of the liquid crystal display, when the power supply circuit, the high-voltage board circuit, the drive board circuit, no matter which link has a problem, such as large filter capacitor bulging, switch tube open, high-voltage package open circuit, lamp damage, MCU chip damage, power supply regulator damage, poor screen cable contact, etc., will make the LCD screen appear black, so at this time, you can only repair the display. (If within the warranty period and after-sales service).

The sixth reason: that is, there is a problem with the boot circuit of the motherboard, or the CPU power supply is abnormal, the north bridge is damaged, etc., etc., etc., will cause the boot, black screen, and the host does not respond, the solution: is to repair the motherboard, (if it is in the warranty period and after-sales service).

The seventh reason: If you can see the black screen of the English letters after booting, it has little to do with the hardware, this is the relationship of the software, generally the system is broken, the main boot record is damaged, the partition table is damaged, the startup items are not set well, and the boot screen is black. In this way, it can be repaired by reinstalling the system, rebuilding the master boot record, rebuilding the partition table, and resetting the first boot item.

Yours is most likely the second reason, which accounts for eighty percent of the black screen that turns on this season.

The above is the relevant information for you to query, please refer to it, I hope to help you Hello! Is there any other question I can ask you to help you with? We look forward to hearing from you again and wish you a happy life!

2. If the memory module is loose or there is a problem with the memory module, disassemble the back cover of the laptop, and reinsert or replace the memory module.

3. The power supply chip of the motherboard is soldered or aged, disassemble the notebook, and then solder.

Want to know the monitor screen automatically black.

What to do? Here's what to do if I bring the Lenovo monitor to automatically black screen, welcome to read!

Lenovo monitor automatic black screen solution method 1:

1. First determine whether it is a computer or a monitor problem, connect the monitor to another computer, if it can be displayed normally, it proves that it is a computer problem.

3. If it is a computer problem, check the contact between the graphics card and the motherboard, the contact between the memory and the motherboard, whether the graphics card is damaged, whether the host starts normally, etc.

Lenovo monitor automatic black screen solution two:

The computer enters sleep mode and cannot wake up, press and hold the boot button until it shuts down completely, and then restarts.

The memory is loose and incompatible, unplug it and reinstall it to try again.

Software conflicts, graphics card drivers.

Lost or modified, enter safe mode.

Uninstall the graphics driver completely, reboot it, and reinstall the graphics driver.

If the system fails, the fastest way is to reinstall the system.

The graphics card is soldered or damaged, and an external monitor can be connected if possible.

The screen itself is damaged.

Lenovo display automatic black screen solution three:

1: The screen is faulty. This kind of failure is mainly caused by the bad backlight tube, and there are also some problems with the backlight tube's circuit, which leads to the failure to light the backlight normally, resulting in only displaying information and no backlight, that is, = screen dimming fault.

Blind 2: The backlight plate is faulty. When the backlight panel fails, it cannot provide the voltage or power of the lighting tube, and there is no backlight display, so the screen is dark.

3: Motherboard failure. If it's an integrated graphics card.

If the motherboard is faulty (the graphics card part), there will usually be a black screen or a white screen failure, depending on whether the signal sent to the backlight is from the motherboard or look first, if it is the motherboard, and this part of the circuit is not faulty, there will be a white screen failure (at this time, the backlight is only lit up and no information is displayed), if it is from the empty card of the display and lead elimination, unfortunately this part of the graphics card is also faulty, there will be a black screen failure.

4: There is another part that can not be underestimated, that is, the connection part between the backlight plate and the screen, if the contact is poor, it will lead to the backlight plate to provide the lamp to work in the conditions are not available, resulting in the screen dark fault. Finally, it is especially important to remind you to see if the sleep lever is pressed, because the sleep lever provides the function of turning off the backlight (because it is easy to cause this kind of failure if it is not installed well, and this is the reason why the laptop does not have a "display" after the screen is turned off).

The easiest way to distinguish whether the graphics card is faulty when the screen is dark is to connect an external monitor to see if there is a display, if there is, it is not a graphics card failure, but a graphics card failure.

Sometimes the computer turns on the black screen do you know what to do, the following is the content I brought about, welcome to read!

1. The monitor screen is black, but the monitor is powered on, and I think it shouldn't be the problem of the monitor. How to verify if there is a problem with the display. a. Unplug the wiring at both ends of the monitor, then reinstall them, and turn on the machine again, and the fault still does not change.

2. Based on experience, how to deal with the first step in this situation? a. Unplugging the memory strip and then reinstalling it can generally solve the problem. Because sometimes the memory bar is loose, this can also happen.

If the problem persists, try something else. b. Unplug the battery and memory strips of the motherboard, and then reinstall them all after three minutes. Keep in mind that these operations must be performed with the power supply cut off.

If the problem persists, try the other way. c. Unplug the motherboard battery, memory strip, hard drive power supply and data cable, then reinstall them all, and try again, if it is not solved, then it is not a problem.

3. Through the above two steps, there is no solution, I thought about changing the memory bar to try it, because there is no boot sound when booting. It's not that there is no boot sound that means that the computer is not normal, if there is no connected speaker, there is no boot sound a, in the company with the same configuration of the computer more, just try it, it is very fast. If it's at home, you don't need to try B in this step, and you can also replace the graphics card with an independent graphics card, which is also a try, and there are problems in this regard.

4. Through the above three steps, the problem is still not solved, so I will consider that it is a problem with the display. The first step is not to suspect that the monitor is broken. How to verify if there is a problem with the display.

a. You can try a different monitor, if everything is normal, you have to consider that there is really a problem with the monitor. I found a monitor to connect to.,Everything is normal when you boot up.,Is it really a problem with the monitor?

5. I connected the computer to the original monitor again, but the screen was still black. I disconnected all the power from the beginning with experience, stared at it for a minute, and then connected it all and turned it on, which made me smile bitterly and the picture appeared, and everything was normal. Nowadays, if there is a problem with electronic products, it is sometimes really useless to do it with experience, but it is a waste of time, but this is a process for us to deal with problems.

6. The VGA connection of the monitor is loose.

In many cases, the display cannot be displayed because the connection between the host and the monitor is loose, so we can just connect it.

7. The memory strip is loose or damaged.

Solution: Use an eraser to wipe the gold finger of the memory bar and reinsert the memory bar; Replace the memory strip.

Take Lenovo Tianyi 510S, win10 as an example: check whether the power contact of the connected notebook is good, whether the power indicator is on, it is recommended to use a multimeter to test whether the power supply of the notebook has a voltage output with the value marked in the spike source label. Rising beats.

After pressing the power button, the computer does not have any response, and there is no indicator light on, most of this situation is the power supply line failure, or the power button failure, it is recommended that the user take it for maintenance.

In addition, if the power indicator is on, the cooling fan port is windy, but the display screen is still black, most of this situation is due to the internal wiring fault or hardware failure of the notebook, such as the internal memory module of the notebook is loose, the graphics card is faulty, and the display panel is faulty. At this time, it is recommended that you use the external monitor of the computer, which is the monitor of the general desktop, and connect it to the external display interface of the notebook, if the display is normal, then you can rule out the possibility of damage to the motherboard and graphics card.

The solution to the black screen of Lenovo laptop boot with only mouse arrows: 1. First of all, it may be a hardware problem. The hardware itself has too many bad sectors, resulting in only the mouse being able to display them.

In this case, you can use a USB flash drive to detect the hard disk, if there are too many bad sectors, the only way is to change the hard disk.

2. Otherwise, it may be that the memory of the C drive is full. This will also lead to a black screen that can only show the mouse, and the solution for this situation is simple, which is to delete some useless files.

3. There is also a situation that the system file is damaged or wrong or the software is malfunctioning, generally restart to enter the safe mode first, if you can delete the recently installed software, try it, if it is not good or the safe mode can not enter, then there is only one simplest and most effective way left in the noisy family is to reinstall the system.

Summary. What to do if Lenovo laptop has a black screen when it turns on.

There are generally two reasons for the black screen of a laptop to boot, one is the system file configuration problem, and the other is the graphics card driver failure. Here's how to fix it:

1. System file configuration problems.

2. Then click "Details" on the left side of the task manager, display the full panel, select the file of task management - run a new task;

3. Then select "Browse" in the lower right corner of the dialog box that appears, and pop up the file browsing window, at this time, you can see the "This Computer" on the left side in the file browsing window, right-click on it, and select "Manage";

5. The "Computer Management" window pops up, select the local user and group user on the left, and the local user will be listed on the right;

6. Create a new administrator account, then log out, log in with the new username, and everything will be normal.

2. The graphics card driver is faulty.

To solve the problem, you need to uninstall the original graphics card driver and install the latest compatible driver. Refer to the above method to open "Manage", select Device Manager, click on the graphics adapter, uninstall the device inside and check Uninstall the driver, and then reboot into the system to update the graphics card driver.
