9 unique skills to save battery power on Win7 notebook

Microsoft recently announced a report entitled “Power Management win7″ the 14-page document white, describes the technology of power management, Windows 7 is the way to reduce power consumption. Windows 7 If you want to know how power and the White Paper will give you the answer. If you just want to look simple and fast, the following will tell you that the primary means of saving 6Y270 Windows 7.

1. Idle power consumption of resources

When a computer starts up, not always running at full capacity, there is a lot of downtime, downtime, energy consumption has become an important technology for energy management. The win7, the idle power consumption is effectively improved when a certain period of time the material does not enter into a state of low power has reached the goal of power. Including the CPU, hard drives, memory and network elements have adopted this technology. For example, a full power operation of the CPU power 35W power consumption during idle time is almost 0, only one will be able to save much power.

2. with the trigger to start the service

System services are generally a time when the system starts at the beginning, and then resides in the background awaiting F2024A appeal. In Windows 7, the part of the service system can not be started until a few triggered by events such as the insertion of a device or change the IP address. This can reduce the lengthy process context where the number of services.

3. Improved power management processor

win7 Village incorporates the latest technology in power management that allows Windows 7 in terms of conditions of the current load and performance requirements to dynamically adjust processor performance.

4. Adaptive adjusting screen brightness

Microsoft said that, usually 10-15 minutes time if no operation, the screen turns off automatically. But in practice, it will be more short-term use of non-operating conditions for improved energy efficiency, technology will reduce the brightness of the screen. In addition, he can enjoy a number of sensor devices to adjust the VGP-BPS2 brightness according to ambient brightness display.

5. Low-Power Audio

Win7 support for low-power Intel HD Audio specification, it allows the codec to enter a low power state. Win7 also supports the selective suspension technology, is in idle state device is turned off, such as microphones and cameras of this type of USB devices.

6. Integration Timer

The current CPU instruction address space by the use of free time to saving energy use, but most energy saving technologies require a certain period of idle time for the energy effect of economy. And this technology by making the Windows kernel at the moment and focus on the termination of the original dispersed multiple timers are eliminated in a short period of time, increasing the downtime of the processor.

In addition, when using the laptop battery cases, win7 would reduce the activities of non-critical frequency processes background.

7. Bluetooth devices to improve energy

When win7 detected Bluetooth devices in a state of low power, as they were temporarily closed, ie “selective suspend.”

8. Network equipment to improve energy

win7 in the radio network controller to compatibility mode for low power has been strengthened, and only in the wireless AP devices support low-power mode where only the opening. Vista, because it could not detect in advance whether to support low-power mode, will lead to a sudden interruption of the wireless network connection. Win7 will prevent this from happening, before entering the low power mode will first be tested as to whether the mode of the wireless PA3191U-3BRS AP.

9. Typical applications of the optimization program

In addition to the improvements listed above, Microsoft has also turned to specific applications, including search, browse without networking and small game. Here is optimized DVD playback program Part of the occasion:

Without affecting playback performance, according to the principle of maintaining the low power mode so that CPU

By changing the structure to improve manager’s office window and consumption of the GPU

Data caching can intelligently reduce the driving speed

These are the win7 in power management, 9 significant improvements compared to the previous system can save more energy. In addition to these improvements, professionals can also be diagnosed with the management of energy research in May that affects the A1008 efficiency of the problem.

Sodium sulfur battery in China

Country State Grid Corporation (China State Grid Corp., known as: national grid), said last week that the company has developed a high energy storage level can be used batteries, sodium sulfur, and thus become a major energy market-wide storage, a major participant.

Storage of large scale energy has recently become the subject of investment in clean energy, because the battery capacity can be resolved wind and solar and other renewable forms of energy facing problems stability.

A large market scale energy storage technology is an emerging market with high intensity. With the national grid to join this market start-ups and established firms will face significant competition and experienced.

Kai Chong peacemakers Venture Management (Shanghai) Co., Ltd. (Weichuang Qiming Venture Capital Management (Shanghai) Co.) Clean Energy Capital Partners, said Zhang Yong, the importance of energy storage is increased, the effective promotion of the network National is very exciting.

National Grid did not answer the question about the Laptop battery to requests for comment.

An understanding of where the battery industry, investors said it could not determine the national network may develop can be put into commercial technology of the production scale. He said the cell of the national grid is more like an R & D project.

He said that some countries with large-scale energy technology storage companies are in cooperation with the national electricity grid, hoping to introduce the technology on the market.

National Grid is not only one of two companies of China’s largest grid power management, China’s largest manufacturer of power equipment, which means that the company has a strong industrial capacity.

At present, over the area of sulfur battery sodium is a leading manufacturer NGK Insulators Ltd. of Japan. The company is the world for a number of pilot projects in small scale to supply the Dell U4873 battery. For example, based in Columbus, Ohio, United States utilities Q (American Electric Power Co. Inc.) were used NGK Insulators of sodium-sulfur batteries to determine its technical performance.

But some other companies are trying to undermine the status of new technologies NGK Insulators. For example, General Electric Company (General Electric Co.) has invested about 100 million U.S. dollars, Niskayuna, New York, the creation of the cell R & D institutions, the goal is sodium sulfur batteries.

These investors have begun to set foot in this area, there are the three largest companies of American venture capitalists invest in projects in North America and China, the battery. Draper Fisher Jurvetson to invest in China-based Prudent Energy Inc., Intel Capital (Intel Capital) invested in the electricity companies of China NetPowerTech Co., and VantagePoint Venture Partners has invested in hp Pavilion dv2000 battery manufacturers in North America Premium Power Corp.

Other technology developers, such as a company A123 Systems Inc. and listed BYD Company Limited (BYD Co., known as: actions BYD) that the electricity market to give them the lithium-ion battery technology and opportunities. Lithium traditional applications of ion battery is the automobile.

The American Society of reflection Electric Power Research Institute, said the electricity market should be added transportation markets, companies like A123 Systems lithium-ion battery technology, a different arena.

Clean Technology Insight reported earlier, lithium-ion toshiba PA3191U-3BRS battery maker Valence Technology Inc. working with the European power generation and transmission company National Grid PLC and Red Electrica de Espana cooperation in trying to develop a battery large scale power.

However, some industry executives electrical energy does not think the battery technology can rechargeable batteries reliably. San Francisco-based Pacific Gas & Electric Co. ’s senior vice president of energy markets Fong Wan, held last week, the Dow Jones Alternative Energy Innovation Conference, said he did not see the successful implementation of technology to large-scale battery. He said PG & E seeks to expand the technique of pumping energy storage using compressed air energy storage is still under study.

While National Grid is the largest company in market power, but industry observers say, this does not mean that the national network will remove all the VGP-BPS10 possibilities of other companies.

McKinsey & Company (McKinsey & Co., Inc.) Director Jonathan A. Shanghai Woetzel said that Chinese enterprises will adopt the best technology available.
