Windows7 System Energy Saving and Emission Reduction Strategy

Energy saving and emission reduction is currently the hottest topic. In order to reduce carbon dioxide emissions and gradually reduce the adverse effects of the greenhouse effect on the earth, people have come up with various ways. Microsoft's Windows 7 system has also designed a variety of strategies to achieve this goal in terms of energy saving and emission reduction. When you are in the office or download state, the computer is not running at full capacity. Therefore, the management of the computer's idle time power consumption has become a key breakthrough technology for Windows 7. Windows 7 users can find that the power consumption of the system is idle or simple, and the power consumption is improved. When a certain hardware does not work for a certain period of time, it will enter a low-power state and save power. Here, the CPU and the hard disk are included. USB, memory, and network cards all use this energy-saving technology.

The following describes how Windows 7 provides energy saving and emission reduction strategies in some special cases.

Energy saving for idle system services. Usually system services are started together at system startup and then residing in the background waiting to be called. In Windows 7, some system services are only started when triggered by some events, such as inserting a device or changing the IP. This reduces the number of long-running services in the background process.

Energy saving for CPU. Windows 7 integrates the latest power management technology that allows Windows 7 to dynamically adjust CPU performance based on current load conditions and performance requirements.

Energy saving for displays. In Windows 7 systems, the display will automatically turn off when you are not operating for a period of time. However, you can also increase the amount of time, and operate in a short time, which can reduce the brightness of the display. It must be pointed out that Windows 7 can also use some sensing devices to adjust the brightness of the display according to the brightness of the surrounding environment.

Energy saving for multimedia. Windows 7 supports Intel's low-power HD audio specification, which enables codecs to enter extremely low power states. At the same time, Windows 7 also supports selective suspend technology, and some devices that are idle, such as microphones and cameras, will be turned off.

Energy saving for timers. At present, Windows 7 processors usually use the gap time of processing instructions to achieve energy saving purposes. This technology increases the idle time of the processor by allowing the Windows kernel to terminate at the same time and centralize the more discrete timers in a short period of time.

Energy saving for Bluetooth devices. After Windows 7 users turn on Bluetooth, they are not running at full load every time, so when Windows 7 detects that Bluetooth devices are in a low-power state, they will temporarily turn them off, that is, "selectively suspend."

Energy saving for network devices. Network devices only run when users have online behavior. In most cases, users can work without networking. Therefore, Windows 7's compatibility with the wireless network controller's low-power mode has been enhanced and will only be enabled if the wireless AP device supports low-power mode.

It should be said that Windows 7 has taken a big step forward on the road of energy saving, which is more energy efficient than Microsoft's previous system, Windows 7. Of course, in addition to these energy-saving strategies, Windows 7 can also help users find the problem of power efficiency through power management diagnostics. More energy-saving strategies are waiting for you to experience further.
