How do netizens who often surf the Internet and watch movies download their favorite video and audio? Take a look with me!
How to download some videos of the website to the local in a common format such as MP4.
Before we start, let's talk about a plug-in IDM needed in this article. Its full name is Internet download manager. It is an excellent download tool, which can sniff audio and video on the web page and download. It supports breakpoint continuation, and has been highly praised by the public for its excellent download performance and user interface.
This software requires a fee. Of course, if you don't want to pay for it, you can learn about the green version on the Internet. It is suggested that you should try to support the genuine version if you have conditions. After all, it is not expensive.
Let's first introduce the download and installation of the software. Normally, we first download the software to the local disk and decompress it. You can see that it contains the IDM main program and the suffix is Expand the application of CRX browser.
Then open the extracted folder and right-click "green uninstall" to run as an administrator.
We directly input the number 1 and press enter in the pop-up command prompt window to complete the greening process. If you need to create a desktop icon, you can enter 3 according to the download. (PS: the installer cannot be found in the programs and functions installed by this method. If your program has problems and needs to be reinstalled, run "green uninstall" as an administrator.)
Is that all? Of course not. We know that IDM is just a download tool, so how to connect it with the browser requires the CRX browser extension plug-in mentioned above.
Here's how to install the extension program offline in chrome. First, we click the three click buttons in the upper right corner of Chrome browser - more tools - to expand the program.
Then drag the downloaded expansion program into it and add the expansion program.
So far, our preparations have been completed. Next, let's verify whether we can realize the function of downloading web video as I said.
Here, a small video of a website is taken as an example to illustrate that when we open a web page with a video page, there will be a "download the video" button in the upper right corner of the video, and we can click to enter the download.
IDM supports all kinds of Web videos and downloads. You can learn about other video websites one by one. Of course, it can also support web audio download. Very convenient and efficient.
I believe you have mastered the method of downloading web audio and video here. That's all for this problem. I hope it will be helpful to you.

Part 1: don't play games with batteries
In the campus, due to the relationship between space and power supply, notebook has become the main platform of games in the dormitory. Although the battery life of notebook computers has made great progress due to the progress of technology in recent years, we must remember: don't play games with notebook batteries.
The reason for this is not only that the power of the notebook can't last long, but also that the high power brought by the CPU and graphics card during the game has serious damage to the lithium battery of the notebook. Each high-power discharge will cause serious loss to the battery itself. On the one hand, the actual power will be greatly reduced, on the other hand, it will also cause the rapid attenuation of battery life. Nowadays, there are fewer and fewer notebooks with detachable batteries, and the cost and difficulty of replacing batteries have soared. Try not to make a dead attempt for your favorite machine and wallet.
First of all, this object is called "memory module", which is not "running memory" or "internal memory" used to store data. Yes, it's the RAM memory module mentioned in the primary school computer textbook.
To get down to business, the most common interface that is prone to problems in notebooks and desktops is the memory module interface. Once something goes wrong, it will lead to failure to turn on, which is commonly known as "no light at all". Therefore, in general, when we encounter the situation that we can't turn it on, we should first check whether there is a problem with the memory module.
If you are sure that there is something wrong with the memory module, don't rush to buy a new one. You can first find an eraser that can be seen everywhere in the school. Wipe the golden interface part (golden finger) with an eraser to remove the accumulated oxide layer, and then plug it back, it is very promising to regenerate the memory module. If it doesn't work, you'd better turn on your mobile phone and buy one.
In addition, how much memory is enough? Now many cost-effective notebooks are equipped with 4GB memory, which can only be said to be barely enough in actual use. It is recommended to add a memory of the same brand, type and frequency to form a dual channel, which can be improved to a certain extent, and the capacity can reach 8GB, which is completely sufficient for daily applications.
Part 3: methods to enhance heat dissipation
Xiaobai's intuitive impression of the quality of the computer is whether the heat dissipation is good or not, and the heat dissipation also has a great impact on the computer, especially on the notebook. So how to enhance the heat dissipation performance of the computer?
Most laptops use air-cooled heat dissipation system, and some desktops use water-cooled heat dissipation, so there is no need to worry about heat dissipation. One of the major problems of air cooling is the poor heat dissipation efficiency caused by dust deposition, so if you feel that your notebook has poor heat dissipation after using it for about a year, you might as well try to remove the dust. Because the disassembly process is complex, if the hands-on ability is not very good, it is recommended to spend some money to find professionals to avoid internal damage due to carelessness.
In addition, the silicone grease responsible for heat conduction between CPU, graphics card and radiator will also denature after a certain time, resulting in a significant reduction in heat dissipation capacity. Whether desktop or notebook, it is recommended to check and replace silicone grease once every two years. After changing, you will find that the temperature of the machine will decrease obviously.
Part 4: beware of static electricity in autumn and winter
In autumn and winter, the north will be very dry. In addition, people wear more chemical fiber clothes, so it is easy to get charged. At ordinary times, we often encounter a slap when reaching for something, accompanied by an electric spark. It doesn't hurt the human body, but it's not the same.
If the human body touches the computer with static electricity, it is easy to have high-voltage discharge. A voltage of tens of thousands of volts is very dangerous for the circuit of the computer, which is easy to burn the circuit. On the other hand, if the computer carries static electricity, most mainboards will have static electricity protection measures, which will automatically cut off the circuit. At this time, the computer can not be turned on at all, and there is no response when pressing the start button. I've experienced this situation myself. The solution is to disconnect the power supply and stand for a few hours, which will generally return to normal.
