Windows system is a computer operating system used by most people now. It is simple and convenient, but some skills may not be known by novices. What is it?
Introduction to skills and methods:
① directly enter "drive letter name: \ file name" in the address, for example, enter C: \ users to open the directory where the corresponding file is located.
② type at the beginning of Notepad document Log, the log here is an uppercase letter, which is invalid in lowercase. Closing the save document will automatically record the current time. This method is suitable for people who frequently use the same document to modify and record events repeatedly. In this way, they can intuitively know the accurate modification events of the document or a field.
③ copy the location of the file as the path. When you frequently use a file, you may encounter the problem of deep path. It is inefficient to open it a little bit every time. This is a good way to copy the file to you.
We can save the copied path in Notepad. Next time, we need to directly copy the path and paste it into the address bar of Windows Explorer. Press enter to open it. Here, pay attention to remove the double quotation marks of the path.
④. Enable the on-screen keyboard. I don't know if you've ever tried. When your hands can't type at the same time when you're eating or busy with other things, just think of a screen keyboard to click.
⑤ skillfully use ALT key. When we need to view the attributes of a file, we usually click the file and right-click the attribute. Here's a simpler and more effective way. When we hold down the ALT key, we can directly double-click the mouse to access the file property panel. This is more efficient when we need to view and compare a large number of files.
Of course, ALT key can also realize various shortcut operations with other keys. For example, ALT + F4 can quickly close the current page or realize shutdown operation, etc.

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.
