The most obvious advantage of laptops, compared to desktops, is the ability to perform a variety of tasks anytime, anywhere, with good portability. However, if a laptop does not have a good performance, even if the performance of a strong appearance and then thin, productivity will be greatly reduced. So when choosing a laptop, battery endurance has also become a very important consideration, and recently foreign media digital trends also selected fiv
upgrade to the Intel fourth generation Haswell Core I series processor, in fact, compared to the most important upgrade of the old model is the significant increase in the battery life, this is the real selling point of the new MacBook Air.
CNET has also tested a number of laptops that use the Haswell processor, and overall, the Haswell processor can improve laptop performance while reducing power consumption, increasing user care. After switching t
WiMAX revolution
WiMAX and voice communication are different from each other. It was initially designed as a wireless IP system. WiMAX not only reduces costs from the perspective of chipset, but also provides services from the perspective of operators' capital expenditure and operating expenditure. Along this path, WiMAX is much cheaper for consumers than 3G or 2G data services.
The WiMAX ecosystem is built around most consumer devices. Therefore, it is only a plug-in for the main purpose of thi
the most avant-garde trend. Therefore, MP3, laptops, and handheld game consoles are the most suitable IT products for them, and computer networks seem to have become indispensable for them every day.
Listen to the needs of college students on the Internet and take a look at the current university campus. On the current university campus, the requirements for the Internet for students are also quite well matched, and the campus network is basically ev
After reading the test results of the PCMark05 software, we will compare the performance of the Vista operating system and Windows XP operating system on the three main components of the video card, processor, and hard disk. For laptops with independent graphics cards, we fully tested their display performance. For Fujitsu P7230 with integrated graphics cards, we only tested 3DMark03.
At the same time, to test the game performance gap between the Vist
Two methods are generally used to connect a PC to a projector: Dual-graphics card or video distributor.
Dual-graphics cards are used, that is, two graphics cards are inserted in one PC at the same time. One video card is connected to the monitor, and the other video card is connected to the projector; the video distributor is used to divide a single video input signal into multiple channels and output the same video signal.
Most laptops have designed

This howto is suitable for people who complain that Ubuntu is slow but do not want to install any tool to speed up. The method I use here is not the final solution, but it does change in any case and it does work. All the following is done by adjusting the Ubuntu boot process, because each person's computer is different, there are some risks-the following things may damage your system. Before you change it, it is always good to make your judgment and make a backup for the/etc
The birth of notebook makes it easy for more friends who often go out. Many features such as lightweight and portable are not available on desktops. However, the volume and noise of the machine limit the heat dissipation system of the notebook, which makes the heat dissipation of many laptops not ideal. Especially in summer, some unpleasant things may occur due to heat dissipation. Therefore, the Auxiliary Heat Dissipation of the notebook seems to be
At present, laptops are increasingly becoming standard office configurations for engineers and technicians. With the increasing influence of the Linux operating system, many Linux users want to be able to run the Linux operating system on their own laptops, so that they can use and study it anytime, anywhere.
Installing Linux on a laptop is basically the same as installing Linux on a desktop. Based on my e

However, tablet computers can achieve superb combat power. This temptation is not strong for ordinary consumers, but for office workers, the image is full. Microsoft's surface Department's senior vice president, Panos banner, said at the press conference that surface pro 3 is suitable for everyone. Although the pop
ibook, PowerBook G4, MacBook, or MacBook Pro, you can calibrate your battery by referring to the Apple's Chinese (Simplified) guide.
The steps for other Macintosh laptops are basically the same: you need to have enough battery (keep it up), then disconnect the battery and use it out of the power until the system automatically sleeps. During this time period, do not charge. After that, you need to recharge the batteries until the battery is full, and
corrected image problems, such as color adjustment and sharpen filters.Core Image analyzes the quality of an image and provides a series of filter to optimize and adjust these, such as chroma, contrast, and hue.The Core image recognizes the face features of still images and can track them in video images. Knowing where your face is, you can decide where to apply the filter.3. Core image has a built-in filter related document. You can query the system
