There is no doubt that environmental protection has become a mainstream. As UN Secretary-General Ban Ki-moon puts it, "the challenges defined in our time." The melting of glaciers on both poles of the Earth is evident in the gradual changes in temperature, rainfall and storms in all regions. As a responsible corporate citizen, Microsoft has spared no effort to contribute to preventing global warming and reducing carbon emissions. Microsoft CEO Steve Ballmer said in an email to employees that Microsoft is committed to a long-term commitment to environmental sustainability. Engaging in energy use and environmental change not only provides a business opportunity, but more importantly, has a major impact on our planet. Indeed, "this is the right thing." Through its strengths in operating system software research, Microsoft has raised the energy efficiency of computers to an unprecedented level. Other business applications, such as OneNote 2007, are also playing an increasingly important role in reducing carbon emissions. You may not pay attention to it, so let me give you a brief introduction. Windows 7 energy efficiency You may have noticed the Windows 7 dazzling desktop. Have you ever thought about what kind of careful design she has done in power management? However, before explaining the energy management of Windows 7, let us first understand the energy consumption of the computer. Going. The components of desktops and notebooks of different brands and models vary widely, and the power consumption of various components varies. Therefore, for Window7 or any other system software, it will be a huge challenge to improve energy efficiency based on these complicated hardware. For a current common laptop, the power consumption is basically as shown in the figure below. Desktops consume more energy, but the proportion of consumption of each component is similar, and the display also accounts for the largest proportion. On this platform, the Windows operating system, like other components, has a major impact on power consumption. The first thing users think of is power management through the control panel or battery management on the laptop. And this is because Windows has developed a power management solution on the system. This solution allows you to easily switch from one power setting state to another. With power management, you can also change a variety of power-saving features, including turning off the display by judging idle time, or automatically adjusting the system to sleep, or even customize the parameters to your liking. . Turning off the display and sleeping is important for power saving and extending battery life. ⊙ Warm Tip: The easiest way to save power on your desktop is to reduce the idle time to 2-5 minutes and the monitor will automatically turn off. In addition, in the notebook, we can also easily extend the battery life by turning down the display brightness. Windows manages the operation of the processor and dynamically adjusts the state of the processor based on the amount of work currently running to reduce energy consumption. For example, when the system is almost idle, as with simple input text, the processor does not need to run at maximum performance. Reducing the voltage and frequency of the processor reduces power consumption, which saves power. Similarly, if the computer is not in use, the hard drive and other devices can enter a low-energy mode or be turned off, thus saving power. Regarding Windows 7, we will focus on reducing the amount of power used when the computer is idle and the power mode that supports the new device. The first step in reducing power usage while the computer is idle is to optimize the amount of processor, memory, and disk usage. It is very important to reduce the utilization of the processor. When truly idle, the processor can consume as little as 100-300 milliwatts. However, when fully operational, the power can be increased to 35 watts. Such a large gap means that a small amount of processor activity can have a significant impact on overall power consumption and battery life. Windows 7 has studied this in several ways. This includes a clever management method: when the service on this platform reaches only one "contact", the corresponding service will be started. In order to reduce power consumption, R&D personnel also focus on improving the energy management of the processor. Windows measures usage based on the number of processors currently used, and ensures that processor utilization is increased only when absolutely necessary. In this way, the consumption of electric energy can also be reduced. OneNote realizes training and paperless meeting. In today's increasingly competitive society, in order to ensure the effective execution of tasks and the improvement of personnel quality, meetings and training have become an indispensable part of our work. Traditionally, these will undoubtedly use paper for meeting recording, preparing training materials, and completing homework. At the same time, people are used to using paper materials to do these things. But have you thought how much paper will be thrown away and eventually become garbage on the landfill? These actions will increase the adverse impact on the environment.
