How do I get windows 7 to conserve battery power?

1. Energy consumption of leisure resources

When a computer starts, will not always be in full load running state, so there will be a lot of leisure time, so the power consumption in leisure time becomes a main technology. In Windows7, leisure when the power consumption has been effectively improved, when a certain hardware will not work after the entry into the Low-power state has reached the goal of saving electricity. This technology is incorporated into the CPU, hard disk, memory, and network sections. For example, a full power power consumption of 35w CPU in leisure power consumption of almost 0, only this one can save a lot of electricity.

　　2. Start the service by triggering

Typically, system services are started together when the system is started, and then reside on the backing expecting call. In Windows7, some system services are triggered only by events, such as inserting a facility or changing IP. This will reduce the number of long running services in the backup process.

　　3. Enhanced Resolver Power Management

Windows7 integrates the latest power-management technology, which allows Windows7 to dynamically adjust CPU performance based on current load conditions and performance requirements.

　　4. Adaptive Display Brightness adjustment

Microsoft has indicated that the monitor will automatically shut down if there is no operation in 10-15 minutes. But in actual use there will be more short time operation, in order to better energy saving, the technology will reduce the brightness of the display. In addition, it can use some sensing facilities, depending on the ambient brightness to adjust the display brightness.

　　5. Low Power Audio

WINDOWS7 will support Intel's Low-power HD Audio standard, which allows the codec to enter a very low power state. The WINDOWS7 also supports a selective hang technology that shuts down idle facilities such as microphones and cameras, such as USB facilities.

　　6. Timer Integration

At present, the solution through the use of the clearance of the gap to achieve energy-saving goals, but most of the energy-saving technology requires the length of leisure time power to obtain energy-saving motives. This technique adds the leisure time of the solution by letting the Windows kernel terminate at the same time and focus on the more evacuated timers in a short period.

In addition, when the laptop is in the condition of using the battery, the Windows7 will cut the movement frequency of the non vital backing program.

　　7. Bluetooth Facilities Power Improvement

When Windows7 detects that Bluetooth devices are in a low-power state, they are temporarily turned off, that is, "trade-off hangs."

　　8. Network Facilities Power Improvement

In Windows7, the compatibility of the wireless network manipulator low power mode is enhanced, but only when the wireless AP facility supports low power mode. Vista is not able to detect in advance is not the support of Low-power mode, will incur wireless network convergence abruptly interrupted. Windows7 will be spared this condition, before entering low power mode will first detect whether the wireless AP supports this mode.

　　9. Optimization scheme of typical utilization

In addition to the improvements listed above, Microsoft has turned its sights on specific uses, including finding, reading no networking and games. Here are some of the optimization scenarios for DVD playback:

Keep the CPU low power mode without impacting playback performance

Improves the power consumption of the Desktop Window manager and GPU by transforming the architecture

Intelligent data caching can reduce the speed of optical drive
