一些新型的主板都具有电源管理功能,可以定时关闭显示器和硬盘,降低CPU的运行速度。这不仅可以节约电力,而且可以保护设备。但是并非所有主板都具有此功能,所以,有很多文章都介绍了在普通机器上实现定时关闭显示器功能的程序。这些程序起到了一定的节电和保护显示器的作用。但我们也应看到,要想起到节能的作用,仅仅关闭显示器是很不够的。在系统中,还存在着一个耗电的“大户”——硬盘。 我们知道,机器接通电源后,硬盘盘片便一直处于高速旋转 Some new motherboards have power management features, you can regularly turn off the monitor and hard disk, reducing CPU speed. This not only saves power but also protects the equipment. But not all motherboards have this feature, so there are many articles on the regular machine to achieve regular shutdown display function of the program. These programs have played a certain amount of power and protect the monitor’s role. But we should also see that, in order to play the role of energy saving, simply turning off the monitor is not enough. In the system, there is also a power hungry “big” - hard drive. We know that after the machine is powered on, the hard drive platter has been spinning at high speed
