The laptop screen fills up when the network is disconnected. When you turn off and connecting charging to the laptop goes out the screen

Some laptop owners may encounter a situation when when you connect the power adapter, the display device darkens. Someone solves this problem, giving a laptop to the service center, while not even suspecting that it is often possible to solve it in literally in a few minutes, the main thing is to determine the cause of this phenomenon.

Incorrect power settings

Quite often, users ask a question: why does the laptop screen darken when charging, after updating OS? The answer may be the fact that during the update process, the laptop power supply parameters can be established randomly, which, in turn, will result in charge saving when the power adapter is connected. This problem is solved as follows:

On the laptop battery icon, which is located on the taskbar, click PCM and select context menu "Power supply."
On the right side of the window, select "Setting the display shutdown", then - "Change additional power options".
Scroll through the menu to the "Screen" point and select the "Screen Brightness" subparagraph. There are two brightness values: when working from the battery and during operation from the network. The value of the second indicator, that is, when the charger is connected, it must be set to an acceptable level for you, for example, 100% is that when connecting to the network, the display brightness will increase to maximum indicators.

It also makes sense to check the adaptive adjustment adjustment parameter - if it is configured in such a way that when the laptop is connected to the network, it is activated, then this may be the reason that the screen darkens if there is a fairly high level of illumination.
After that, press the "OK" button so that the settings are saved.

Customize BIOS.

Another common reason for which the laptop screen can guess when charging - the BIOS settings responsible for the operation of the video adapter. To change them, when you turn on the device, it is necessary to clamp F2 or DEL, after which, in the BIOS opened, do the following:

Select the "Main" tab, in which to find the line "Graphic Mode" or "Graphic Device".
Press the "ENTER" key on it, and set "Discrete" in the context menu that appears.
After that, press the F10 button and save the changes made.

Problem with video card software

In modern laptops, it is usually two video cards - integrated and discrete. Discrete displays the image during the execution of everyday tasks, such as the use of various programs, video viewing and so on. Integrated, in turn, is responsible for processing the image when the "demanding" 3-D applications are started, such as computer games.

On each video recorder is its driver and, as often it happens, during the next system update, the driver is installed correctly on the discrete video card, and there is no integrated. In this case, if the appropriate settings are set on the laptop when an integrated video card is included in the network to work, various problems with the operation of the display may appear, in particular, its dimming. Of course, you can change the parameters in the power settings in such a way that a discrete video card continues to operate when powering from the network, but it does not differ in the performance, moreover, its service life will be significantly reduced.

You can solve this problem with a system kickback to a state when all components worked correctly. For this:

Go to the "Control Panel" and find the section "Restore".
Select "Running system restore", wait until the system prepare for operation and click "Next".
You will find a list of points, indicating the date and time of creation. By choosing a point, during the creation of which your computer has been working properly, you need to click "Next", and then "ready" to start the operation.

Upon completion of the process, incorrect installed Drivers Will be deleted, and the problem of dimming the screen when the laptop is connected to the charger must be eliminated.

If nothing helped

If, after performing the described methods, the answer to the question "why a darker laptop screen during charging" was not found, and the display continues to darken when connecting to the charger, most likely there are problems with the hardware component of the device. In this case, if you do not have suitable knowledge and skills, it is best to give a laptop to a service center.

A similar problem with MS-1761. Turns off under load.

Reducing the vuliteration on the video card (570m) from 0.81V at 0.80V did not help. (Rather, it helped, but partly - the laptop turns off early or later).

It also partially helps dancing with a tambourine through the power plan in which in the section: "Processor Power Management" set in the menu: "Maximum CPU Condition" value is less than 100% (even with a value of 99% of shutdowns becomes less).

Well, and naturally, you can lower the frequencies on the video card itself, but there are other races in the form of switching from 3D mode in 2D at which, most likely, somehow "sticks 2D mode and when a re-transition in 3D mode, FPS drops significantly. A simple example - This is a combination of Alt + Tab from the game on the desktop and back. But the sediment does not always happen, but by the random principle, return the position can be increased by increasing frequencies on the video card to factory or close to them, and then again to reduced frequencies in which the laptop worked stable, But it does not always work, and not the first time, and often when renewing the normal number of FPS, with low frequencies, after these all actions, the laptop is cut off again.

Also noticed that the THRM sensor began to warm motherboard (This is most likely one of the bridges). Ensure the chronology I no longer remember after which he began to warm up, but the temperature can reach 89 and above the degrees, after which the laptop naturally turns off (I was just lucky to see a few times the temperature before the disconnection). And he is heated regardless of the battery or from the network, the NotBuk is subtracted. (I turn on the laptop on the battery Run a browser with a multitude of windows and voila see the temperature on the sensor close to boiling water while the windows are loaded, then the temperature drops, but still remains in the area of \u200b\u200b70-75 degrees)

That's just today I tried to change the processor. Its 2720m for 2760Qm and shutdowns became different, I didn't wait for a disassembled form, and when they collected them again, but this time it was enough to lower the state of the processor to 98% and everything works stably and with the factory video card frequency settings (with understated voltage)

As a result, it is interested in the opinion that everything is not like this here:
_Chipset (sobering I saw a miserable semblance of a radiator from a piece of thin metal, but the replacement for a normal radiator did not help)
_ Power ManagementBlock (when the battery is disconnected, can sometimes be disconnected if you shoot the power plug in the laptop slot)
_Videocard (B. service center There is no video card under the substitution, to test, seemingly no signs of physical defects as a result of overheating or any other effects. At the very beginning of the emergence of problems there were minor artifacts, but then they disappeared and no longer appear)
_Processor (which is unlikely since the new still turned off)
_complex problem associated with multiple components

I looked after myself a video card 675m, judging by several reports on this forum and others, it should be approached as it is also based on the Fermi family, and the Americans (they took a laptop) they answered that the maximum possible video editor this same 570 for 580 need more Nutrition, and for the next generations, they did not speak.
So it is possible to take this video card (675m) which was removed from MS-1762 (MSI GT 70) to install in my MS-1761.

I would be grateful to any answers in essence, as I already "flashed" I fight with my laptop. No strength.

Faced a problem on the ASER 5820TG laptop when connected charger Fully turns off the screen(It only seems at first glance, actually goes out the screen backlight), but the system continues to work, it can be seen if you shine a flashlight on the matrix. Food is noticeably, but still visible and desktop, and in general you can work, however, the cursor is difficult to find. If the charger is pulled out, the screen lights up again. So why does the laptop go out the screen? And so, I propose a solution to this problem, or rather even three options that I met in practice. I did not find the answer on the Internet. I am confident that many have come across such a task, so I think that the post will be extremely useful, because he is one of its kind.

I will immediately say, the problem is neither the matrix or in nutrition, nor in any other laptop device. Mystery solutions lies in bIOS settings. When the laptop is turned on, press F2 ,. Arrows select the tab Main., we find a string Graphicmode., press ENTER, instead Switchablechoose Discrete., Click ENTER, then saved by calling the command through the F10 button, confirm the saving.

In practice, he met three more cases where the laptop screen goes out.

The first case after reinstalling the OS, or rather after setting the video driver to the video chip. from driver programs Pack Solution. It turned out that DPS catalog software HD 7450M, and the chip was HD 7470m. After installing the driver from the official site of the manufacturer, the problem is gone.
The second case occurred after disassembling / assembling a laptop. The cooling system was cleaned, thermoelements and isolation between the cooler and the copper tube were replaced. The habit was changed to heat-resistant aluminum isolation, and when contacting with motherboard A closure occurred, in connection with which on the GAS screen laptop. The replacement for ordinary insulation solved the problem.
The third case turned out to be a burned transistor on the motherboard. With a similar problem, you can face quite rarely. More often happens with a short circuit.

Do not confuse with the absence of backlight. If it helped, we rejoice! Everyone is happy, everyone is satisfied! Do not forget to subscribe to new useful articles.

After installing the operating system, Windows 7 users and above may encounter a problem when the laptop screen when connecting and disconnecting the charger shock. However, it is worth distinguishing the symptoms when the screen is just a few seconds, and the system continues to work and when the screen becomes dark and the desktop is poorly visible. Therefore, consider examples of solving each problem separately.

Goes out the screen when charging / connecting / connecting

If you recently reinstalled operating system and collided with a problem when the laptop screen with intel processor It goes out when connected to charging (or when disabling), then you should perform the following steps:

Open the Intel HD-Graph Control Panel. Select the section "Power".

In the "Switching Screen Update Frequency" section, set off.

Next, choose the plan "running from the network".

It is worth noting that this problem is associated with switching graphics display modes. Therefore, so that the screen did not go out, it is worth it to switch off.

You can also try to reset the power settings. To do this, go to the "Control Panel", select "Power Supplies". Next, select "Power Plan Settings".

Select "Restore for the default settings plan".

We save changes.

Running laptop screen when charging connected, but the desktop is weakly visible

This problem is related to the BIOSA settings. To solve it, do the following:

When you turn on the laptop, click several times "F2" to get into the BIOS.
After moving to the "Main" tab and looking for a "Graphic Mode" or "Graphic Device" string. Click "ENTER". Set the value "descrete".

Click "F10" to save the result.

You should also roll back the video card driver if such an error occurred without reasons after the next computer turn on.
