Users want mobile office with a laptop, it is most worried about is the laptop's battery is not enough, what skills make laptop batteries last longer in Win7, change what settings win7 laptop to let it use up more power, the following to see how to set up Win7 for laptop battery last longer.
1, the energy consumption of free resources
When a computer starts, not always running at full load condition, so there will be a lot of idle time, idle time, power consumption has become an important power management technology. In win7, the idle power consumption is effectively improved after a certain period of time the hardware does not work it will enter a low-power state has to save battery power. Including CPU, hard drive, memory and network elements have adopted this technology. For example, a full power run power 35w of the CPU power consumption at idle is almost 0, only this one will be able to save a lot of power.
2, Bluetooth devices to improve power
When win7 detected Bluetooth devices in a low-power state, they will be temporarily closed, or "selective suspend."
3, increased processor power management
win7 incorporates the latest in power management technology, which enables Windows 7 to dynamically adjust CPU performance based on the current load conditions and performance requirements.
4, low-power audio
win7 will support Intel's low-power HD audio specification, which allows encoding *** into low power state. win7 also supports selective suspend technology to shut down idle equipment, such as microphones and cameras such USB devices.
5, through the trigger to start the service
System services are typically started at system boot time together, and then wait for the call resides in the background. In Windows 7, the service is only part of the system is triggered by some event will start, such as inserting a device or change IP. This can reduce the number of services in the long-running background processes.
6, adaptive display brightness adjustment
Microsoft said, usually without the operation, the display will automatically turn off in 10-15 minutes time. But there will be no more short-term operating conditions in actual use, in order to better energy efficiency, this technology will reduce the brightness of the display. In addition, it could use some sensing devices to adjust the brightness according to ambient brightness of the display.
7, network equipment to improve power
win7 compatibility for wireless network controller in low power mode has been strengthened, and only in the device supports low-power wireless AP mode is enabled only. Vista because it can not detect in advance whether to support low-power mode, it will lead to a sudden interruption of the wireless network connection. win7 will prevent this from happening, before entering a low power mode will first detect the wireless AP support this mode.
8, integrated timer
Currently processor by utilizing spare time gap processing instructions to save energy, but most free time saving techniques require a certain length in order to obtain energy savings. And this technology by making the Windows kernel originally terminated and focus more dispersed multiple timers at the same time, the processing is completed in a short time, thus increasing the idle time of the processor. In addition, when using the battery in the laptop case, win7 will reduce the frequency of non-critical activities daemon.
The above is win7 several important improvements in power management, compared to the previous system can save more energy. After the above through improved laptop battery life has been extended under certain Win7.
