Welcome! This blog is dedicated to the Internet and computers, or rather was dedicated to them.

It’s probably immediately obvious that no new articles have appeared on the site for many years. Yes, this is the fate of most blogs. This project was once an ambitious undertaking, and the author, like many others writing at that time, had ambitious plans to become one of the best Russian bloggers. Well, if you look now, of those blogs that were created simultaneously with mine, most have already disappeared into eternity. And I just simply didn’t have enough time to blog. So yeah, it's not updated anymore. Although we once won the “Runet Blog 2011” competition with this site.

I even had the idea of ​​deleting all this, but then I reviewed the old materials and realized that they could still be useful to readers. Yes, some articles are outdated (if I have enough strength, they will be marked accordingly), but the site, for example, can be useful for beginners - here you can read about the basic concepts of the Internet, learn how to set up the Internet, Windows, or even decide to switch to Linux. So take a look at the categories and choose the one that suits you.

And yet, I hope that this is more than just a blog, but a real guide to the Internet. The site can be viewed in directory mode, where all available articles are structured by categories. And, who knows, maybe one day new high-quality articles will start appearing here.

Picodi.ru is a discount portal from International Coupons, a Polish expert in the field of savings and cheap shopping. The Poles are considered one of the most frugal nations in the world, so it is not surprising that this type of project grew out of the Polish startup kodyrabatowe.pl. How can this portal be useful to the average Internet user in Russia?

Modern Android phones are more than just phones. You get used to the set installed programs, to your call and text message history, photo collection and much more. But time passes, and the device that you were completely satisfied with begins to slow down, glitch, or simply loses its presentable appearance due to chips on the body or scratches on the screen. The question arises of choosing a new phone and changing android phone. And if we now bypass the question of choice, then “moving” to new phone remains a serious problem - I absolutely don’t want to start all the data from scratch. This is what we will talk about today.

Most of the readers of this blog have most likely never encountered version control systems and will not encounter them in the near future. It's a pity. This extremely convenient invention is quite widely used by programmers, but, in my opinion, it could also be very useful for those who actively work with texts. But, probably, now there is not a single version control system that would be easy to start using for “office” ( Microsoft Office) work. Nevertheless, I think that the material presented in the article may be of interest to all readers.

If you have been wondering how to watch movies online and access the Internet from your TV, this article is for you. No, I know that some TVs already have Smart TV functionality, but I have never seen it work properly. Apparently, this is why Google recently demonstrated an absolutely stunning device that immediately became a sensation. We are talking about the Chromecast media streamer (Chromkast), a more advanced and available version last year's disastrous Nexus Q player.

The Chromecast dongle, whose dimensions do not exceed 2 inches, connects to the HDMI port of the TV and allows you to enjoy watching streaming web content. To control the streamer, you can use any device (tablet, PC, smartphone) based on the operating platform iOS, Windows, Android or Mac OS.

This article is about the device system memory android, problems that may arise due to its lack and ways to solve them. Not long ago I myself was faced with the fact that my phone is on android base began to regularly display messages about low memory when trying to install this or that application. Which was very strange for me, given that according to the description on the market there should have been about 16GB, and I also increased this volume using additional card memory. However, there was a problem, and it took a lot of fiddling around before I found the right solution that didn’t require root access or completely restoring the phone to its factory state.

After installing the operating system Windows users 7 and above may experience an issue where the laptop screen when connected and disconnected charger goes out. However, here it is worth distinguishing between the symptoms when the screen goes dark for just a few seconds, but the system continues to work, and when the screen becomes dark and the desktop is difficult to see. Therefore, we will consider examples of solving each problem separately.

Screen goes blank when charging is disconnected/connected

If you have recently reinstalled operating system and encountered a problem when the laptop screen was Intel processor goes out when connected to charging (or when disconnected), then you should perform the following steps:

• Open the Intel HD Graphics Control Panel. Select the “Power Options” section.

• In the “Switching screen refresh rate” section, set it to “Disable”.

• Next, select the “Powered from the network” plan.

It is worth noting that this problem is associated with switching graphics display modes. Therefore, to prevent the screen from going dark, you should disable this switching.

You can also try resetting your power settings. To do this, go to the “Control Panel”, select “Power Options”. Next, select “Power plan settings.”

Select “Restore plan settings to default.”

Save the changes.

The laptop screen goes dark when charging is connected, but the desktop is barely visible

This problem is related to the BIOS settings. To solve it you should do the following:

• When you turn on the laptop, press “F2” several times to get into the BIOS.
• Then go to the “Main” tab and look for the line “Graphic mode” or “Graphic device”. Click “Enter”. Set the value to “Descrete”.

• Click “F10” to save the result.

It is also worth rolling back the video card drivers if such an error occurs for no reason after turning on the computer again.

Some laptop owners may encounter a situation where the device display darkens when connecting the power adapter. Someone solves this problem by giving the laptop to service center, at the same time, without even suspecting that you can often solve it yourself in just a few minutes, the main thing is to determine the cause of this phenomenon.

Incorrect power settings

Quite often, users ask the question: why does the laptop screen darken when charging after updating the OS? The answer may be the fact that during the update process, the laptop's power settings can be set in an arbitrary manner, which, in turn, will lead to battery saving when connecting the power adapter. This problem is solved as follows:

1. On the icon laptop batteries located on the taskbar, right-click and select “Power Options” from the context menu.
2. On the right side of the window, select “Settings to turn off the display,” then “Change advanced power settings.”
3. Scroll the menu to the “Screen” item and select the “Screen brightness” sub-item. Two brightness values ​​will appear: when running on battery power and when running on mains power. The value of the second indicator, that is, when the charger is connected, should be set to a level acceptable to you, for example, 100% - this means that when connected to the network, the brightness of the display will increase to maximum levels.

It is also worth checking the adaptive brightness setting - if it is set in such a way that when you connect the laptop to the network, it is activated, then this may be the reason why the screen darkens if the room has a high enough light level.
After that, click the "OK" button to save the settings.

Setting up the BIOS

Another common reason why a laptop screen may go dark while charging is the BIOS settings that control the operation of the video adapter. To change them, when turning on the device, you need to hold down F2 or Del, and then, in the opened BIOS, do the following:

1. Select the “Main” tab, in which find the line “Graphic mode” or “Graphic device”.
2. Press the “Enter” key on it, and select “Discrete” in the context menu that appears.
3. After that, press the F10 button and save your changes.

Video card software problem

Modern laptops usually have two video cards - integrated and discrete. Discrete displays images during everyday tasks, such as using various programs, watching videos and so on. The integrated one, in turn, is responsible for image processing when running “demanding” 3-D applications, such as computer games.

Each video adapter has its own driver and, as often happens, during the next system update, the driver is installed correctly on the discrete video card, but not on the integrated one. In this case, if the appropriate settings are set on the laptop, when the integrated video card is turned on when powered from the network, 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 so that the discrete video card continues to work when powered from the network, but it will not differ in performance, moreover, its service life will be significantly reduced.

This problem can be solved by rolling back the system to a state where all components worked correctly. For this:

1. Go to “Control Panel” and find the “Recovery” section.
2. Select “Run System Restore”, wait until the system prepares for the operation and click “Next”.
3. A list of points will open in front of you, indicating the date and time of creation. Having selected a point during the creation of which your computer worked properly, you need to click “Next” and then “Finish” to begin the operation.

Upon completion of the process, incorrect installed drivers will be removed, and the problem of screen dimming when connected to laptop charger must be eliminated.

If all else fails

If, after following the methods described above, the answer to the question “why is the laptop screen darker when charging” is not found, and the display continues to darken when connected to a charger, most likely there are problems with the hardware of the device. In this case, if you do not have the appropriate knowledge and skills, it is best to take the laptop to a service center.

I ran into a problem On the ASER 5820TG laptop, when the charger is connected, the screen turns off completely(this only seems at first glance, in fact the screen backlight goes out), but the system continues to work, this can be seen if you shine a flashlight on the matrix. It's not noticeable, but you can still see the desktop, and you can generally work, although the cursor is difficult to find. If you unplug the charger, the screen lights up again. So why does my laptop screen go blank? And so, I propose a solution to this problem, or rather even three options that I came across in practice. I couldn't find an answer on the Internet. I am sure that many have encountered a similar problem, so I think that the post will be extremely useful, because it is one of its kind.

I’ll say right away that the problem is neither in the matrix, nor in the power supply, nor in any other device of the laptop. The secret of the solution lies in BIOS settings. When you turn on the laptop, press F2, . Use arrows to select a tab Main, find the line Graphicmode, press Enter instead Switchable choose Discrete, press enter, then save by calling the command via the F10 button, confirm saving.

In practice, I came across three more cases where the laptop screen went blank.

• The first case is after reinstalling the OS, or rather after installing the video driver on the video chip. from the Driver Pack Solution program. It turned out that DPS was rolling software on HD 7450M, and the chip was HD 7470M. After installing the driver from the manufacturer's official website, the problem went away.
• The second incident occurred after disassembling/assembling the laptop. The cooling system was cleaned, thermocouples and insulation between the cooler and the copper tube were replaced. Out of habit, they replaced it with heat-resistant aluminum insulation, and upon contact with motherboard a short circuit occurred, and as a result the screen on the laptop went blank. Replacing with regular insulation solved the problem.
• The third case was a burnt-out transistor on motherboard. It is quite rare to encounter such a problem. More often happens with a short circuit.

Do not confuse this with the lack of backlighting. If it helps, then rejoice! Everyone is happy, everyone is satisfied! Don't forget to subscribe to new useful articles.
