users want to bring a laptop to work. The most worrying thing is that the battery power of the notebook is not enough. What are the skills to make the laptop battery use longer under Win7? Settings can make notebooks more power-efficient. Let's take a look at how to set up Win7 to make laptop batteries last longer.
1, energy consumption
free resources when a computer starts, not always running at full load state, so there will be a lot of idle time, idle time, power consumption It has become an important technology in power management. In Win7, the power consumption during idle time is effectively improved. When a certain hardware does not work for a certain period of time, it will enter a low power state and achieve power saving. This technology is used in the CPU, hard disk, memory and network parts. For example, a CPU with a full power consumption of 35w consumes almost zero power when idle, and this alone can save a lot of power.
2, Bluetooth devices to improve power
Win7 detected when the Bluetooth device is in low power state, they will be temporarily closed, i.e., "selective suspend."
3, enhanced processor power management
Win7 integrates the latest in power management technology, which enables Windows7 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, it allows *** ed into the low power state. Win7 also supports selective suspend technology to turn off devices that are idle, such as USB devices such as microphones and cameras.
5, to start the service by triggering
System services are typically started at boot time together, and then resides in the background waiting for calls. In Windows 7, some system services are only started when triggered by some events, such as inserting a device or changing the IP. This reduces the number of long-running services in the background process.
. 6, the adaptive adjustment of the display luminance
Microsoft, which normally operate at no time 10-15 minutes, then the display will automatically shut down. However, there will be more short-term no-operations in actual use, and in order to save energy, the technology will reduce the brightness of the display. In addition, it can use some sensing devices to adjust the brightness of the display according to the brightness of the surrounding environment. Case
7, network device power consumption for improved compatibility
Win7 radio network controller in a low power mode has been strengthened, the wireless AP apparatus supports only a low-power mode Will be enabled. Vista can cause a sudden interruption in the wireless network connection because it cannot detect in advance whether it supports low-power mode. Win7 will avoid this situation and will first detect if the wireless AP supports this mode before entering the low power mode.
. 8, the current timer integrated processor
conserve power by utilizing spare time interval to process instructions, but most energy-saving technology requires a certain length of idle time to get energy saving effect. This technology increases the idle time of the processor by allowing the Windows kernel to terminate at the same time and concentrate on a plurality of timers that are more dispersed. In addition, when the notebook is using a battery, Win7 will reduce the frequency of activity of non-critical daemons.
