【geek头脑装备】 如何延长笔记本电池的待机时间（[geek brain equipment] how to extend the standby time of laptop batteries） [Geek brain equipment] how to extend the standby time of laptop batteries? 2011, 06, 09, 15:59:08 Users are very concerned about how to extend their laptop standby time, hoping to get longer battery life, the following on how to extend the notebook standby time to explain. Reduce screen brightness Open Speed Step Properly shut down unused equipment Save energy settings on other devices Avoid using external equipment as much as possible Set up the power management mode Reduce screen brightness Notebook LCD screen, and the LCD screen brightness on the battery power is very large, users can use the battery when appropriate to reduce the screen brightness, can effectively improve battery life time. Users can use Fn+F9, F10 (different models to adjust the screen shortcut key) to adjust the brightness of the screen immediately. Open Speed Step As a core unit of a computer, CPU is also a power hungry person. In order to reduce the power consumption in some situations where the CPU computing ability is not high, CPU manufacturers have developed power-saving technologies for their mobile products. One of the most effective is the Speed step function. In short, the Speed step function is to reduce the power consumption of the CPU by reducing the operating voltage and operating frequency of the CPU when using the battery. The Speed Step function can be switched on in BIOS, and the corresponding chipset drivers need to be installed, so that the energy saving control of the chipset is guaranteed simultaneously. There are two aspects in the chip group take at present, one is the operation frequency and reduce system similar to CPU bus to reduce power consumption; another way is according to the performance requirements of the users, dynamically closed or partially open the function of CPU bus or memory bus, in order to reduce energy consumption. For some chipsets, Intel also has a
