9 unique battery saving skills for Win7 laptops

Microsoft announced recently a report entitled “Win7 Power Management” 14-page white paper describes the technology of energy Windows7 management is how to reduce energy consumption. If you want to know how Windows7 power, and the White Paper will give you the answer. If you just want to look simple and fast, the following will tell you that the primary means of saving energy Windows7. Sony VGP-BPS8 Sony VGP-BPS8A

 

1. Idle power consumption of resources

 

When a computer starts up, not always running at full capacity, there is a lot of downtime, downtime, energy consumption has become an important technology for energy management. The win7, the idle power consumption is effectively improved when a certain period of time the material does not enter into a state of low power has reached the goal of power. Including the CPU, hard drives, memory and network elements have adopted this technology. For example, operating at full power 35W CPU power consumption when idle power is almost 0, only one will be able to save much power.

 

2. With the trigger to start service

 

System services are generally a time when the system starts at the beginning, and then resides in the background awaiting appeal. In Windows7, the shares of system services can not start until a few triggered by events such as the insertion of a device or change the IP address. This can reduce the lengthy process context where the number of services. Sony VGP-BPS9 Sony VGP-BPS9/B

 

3. Improved power management processor

 

Win7 Village incorporates the latest technology in power management, allowing Windows7 depending on the conditions of the current load and performance requirements to dynamically adjust processor performance.

 

4. Adaptive adjusting screen brightness

 

Microsoft said that, usually 10-15 minutes time if no operation, the screen turns off automatically. But in practice there will be more than a short-term use of non-operating conditions, for better energy efficiency, technology will reduce the brightness of the screen. In addition, he can enjoy a number of sensor devices to adjust the brightness according to ambient brightness display.

 

5. Low-Power Audio

 

Win7 support for low-power Intel HD Audio specification, it allows the codec to enter a low power state. Win7 also supports the selective suspension technology, is in idle state device is turned off, such as microphones and cameras of this type of USB devices. Sony VGP-BPL8 Sony VGP-BPL8A

 

6. Integration Timer

 

The current CPU instruction address space by the use of free time to saving energy use, but most energy efficient technologies require a certain period of inactivity for energy-saving effect. And this technology by making the Windows kernel at the same time and focus on the termination of the original dispersed timer multiple eliminated short term, increasing the downtime of the processor.

 

In addition, when using the laptop battery cases, win7 would reduce the activities of non-critical frequency processes background.

 

7. Bluetooth devices to improve energy

 

When win7 detected Bluetooth devices in a state of low power, as they were temporarily closed, ie “selective suspend.” Sony VGP-BPS2 Sony VGP-BPS2A

 

8. Network equipment to improve energy

 

Win7 in the radio network controller for compatibility in low power mode has been enhanced, and only in devices for wireless access to support low power mode where only the opening. Vista, because it could not detect in advance whether to support low-power mode, resulting in a sudden interruption of the wireless network connection. Win7 will prevent this from happening, before entering the low power mode will first be tested as to whether the mode of the wireless AP.

 

9. Typical applications of the optimization program

 

In addition to the improvements listed above, Microsoft has also turned to specific applications, including search, browse without networking and small game. Here is optimized DVD playback program Part of the occasion: Sony VGP-BPS2B Sony VGP-BPS2C

These are the win7 in power management, 9 significant improvements compared to the previous system can save more energy. In addition to these improvements, professionals can also be diagnosed with the management of energy research in May that affects the efficiency of the problem. Sony VGP-BPS9/S Sony VGP-BPS9A
