降温管理（Cooling management） Up to ten degrees down, notebook cooling skills summary 2011, 05, 15, 00:01 IT168 website original author: organize, compile, edit: Zhang Huawei comment: 4 Cool down so simple, notebook cooling soft method The so-called soft method is a method to achieve the cooling effect by software, through the power management mode adjustment of operating system power management and graphics to achieve, at the same time, it is also the most simple but also do not have to spend a penny tricks. How do you cool your laptop by power management? We now commonly used Windows 7 operating system as an example, we all know that web browsing, instant messaging, Internet chat, audio and video playback, surfing the Internet, word processing, file download these applications, CPU on the performance requirements of the notebook computer is very low, this notebook CPU often lie idle. First let me take a screenshot of the CPU occupancy rate when I write this article: CPU occupancy screenshot The notebook can work in CPU to reduce the frequency of energy saving status. So the first step in controlling the amount of heat you get from a notebook is to set the systems power management program right. What role does the power management program have in mind? Its most important function is to provide an operating system that is on-demand switching support. On demand switching (DBS) is the use of ACPI processor performance status (dynamic adjustment of voltage and frequency) to respond to system workloads. Windows processor power management uses adaptive processor restriction policies to implement DBS. This policy automatically adjusts the current performance status of the processor automatically to respond to the use of the system CPU without user intervention. Is what we usually call the dynamic frequency modulation technique, support the technology CPU in the case of small load, automatically reduce the operating frequency and voltage, the CPU occupancy rate increased under
