Users want to take the laptop mobile office, most worried about is the laptop battery is not enough, what skills to make longer notebook battery in Win7 win7 change which is set to make laptop use more energy to do the following take a look at how to set Win7 Asus K72J Battery use longer.
1, the idle power consumption of resources
When a computer is started, it will not have been in full-load operation state, and therefore there will be a lot of idle time, idle time, power consumption has become an important technology in power management. In win7 years idle power consumption has been effectively improved, after a certain period of time does not work in a hardware will enter a low power state to save battery power. CPU hard disk, memory and network elements are using this technology. For example, a full-power operation power consumption 35w CPU idle power consumption is almost zero, only this one will be able to save a lot of electricity.
2, Bluetooth devices to improve power
Win7 detected Bluetooth devices in a low-power state, it will temporarily shut down, that "selective suspend".
Enhanced processor power management
The win7 integrates the latest power management technology, which enables Windows 7 according to the current load and performance
Requirements to dynamically adjust CPU performance.
4, low power audio
win7 will support Intel's low-power HD audio specification, which allows compiled *** into low power state. win7 also supports selective suspend technology, will be in the idle state device is turned off, such as microphones and cameras such USB devices.
5 to start the service by triggering
System services are typically started when the system starts, then resides in the background waiting for the call. In Windows
7, part of the system services only triggered by some event will only be activated, such as inserting a device or change the IP. This can reduce the number of long-running services in the background process.
Adaptive display brightness adjustment
Microsoft said, usually 10-15 minutes-free operation, the display will automatically turn off the computer always restart automatically. But in actual use, there will be more short-term operating conditions in order to better energy efficiency, the technology will reduce the brightness of the display. In addition
It can also use some sensing devices to adjust the display brightness according to the ambient brightness.Asus A32-K52 Battery
7, the network devices to improve power
win7 been strengthened in low-power mode for the radio network controller compatibility enabled only, and only in the case of wireless AP devices support low-power mode. Vista because it can not detect in advance whether or not to support a low-power mode
Type, memory repair BIOS maintenance will lead to a sudden interruption of Wi-Fi. win7 will prevent this from happening, will first detect whether the wireless AP support this mode before entering low-power mode.
8, timer integration
Processor through use spare time for processing instructions gap to achieve energy-saving purposes, but most of the energy-saving technologies require a certain length of idle time to get energy saving effect. This technology by the Windows kernel to terminate the focus was more dispersed multiple timers at the same time, dealt with in a short period of time, thus increasing the processor idle time. In addition, the frequency of activities in the case of using the Asus k50ij Battery when the laptop, win7 will reduce non-critical daemon.
The above is win7 several important improvements in power management, compared to the previous system can save more energy. 3F} K rG above improvements in Win7 laptop battery use time must be extended.
