Windows 7 download also saves energy and emissions

The current HD video capacity is getting bigger and bigger, a few GB, and a high-definition "Avatar" will be 46GB, not to mention the increasingly hot HD series. Even if you are using a 2Mbps broadband network, it takes a long time to download these "big guys". When the concept of environmental protection is strongly advocated by the society, those who hang up the download all night are paying attention. For our green environment, let the downloads also “energy-saving”!

Enable the Windows system to leave the mode, save electricity by four points. A

If your computer is idle for most of the time, just for downloading, it is very wasteful, then you can use "leave download". In the WindowVista/Windows7 system, the leave mode is added. This mode can directly shut down most of the devices and only retain the normal power supply of some key devices, thus saving power.

It is different from hibernation and standby mode. In the exit mode, normal file download can be maintained, which is equivalent to solving the contradiction between fish and bear's paw.

1.Activate leaving mode under WindowsVista/Win7

In the WindowsVista/Windows7 system, although the leaving mode is included, it is not activated by default. The activation method is as follows:

Press Win+R, type “regedit” and press Enter. In the open registry editor, expand to [HKEY_LOCAL_MacHINE/SYSTEM /CurrentControlSet/Control/sessionManager/Power] and create a new name under it called “AwayModeEnabled”. DWord32 bit item, set its value to 1 to restart. In the future, just click the "Sleep" button in the "Start" menu to enter the "Away Mode".

When using the leave mode, it is recommended to set the hard disk to never turn off in the power management, that is, "close the hard disk after this time" is set to "0", and "turn off the monitor and then go to sleep" is set to "Never", set "Wireless Adapter Settings" to "Maximum Performance".

2.Grafting and leaving mode in WindowsXP

Download and unzip the "AwayMode" software, import the registry file, and then double-click "AwayMode-KB902437-ENU.exe", then run "away mode" Chinese patch", restart the computer. Open the power option in the control panel, and add a "Leave" tab, check "Enable Leave Mode".

After enabling the exit mode, press the sleep button on the keyboard and the system will enter the exit mode.

Power saving analysis: We used the power consumption meter to measure the power consumption of the normal mode download and leave mode download. The power consumption is 104W in normal mode and 79W in away mode. Energy saving rate = (104-79) /104 × 100% = 24.04%.

It can be seen that in the simple download of files, starting the exit mode can save about a quarter of the power. If you are an energy-saving supporter, will pure hang-up downloads still work in normal mode?

Let the Windows system be diligent "Electric"

When you use your computer in peacetime, you may not play large games from time to time, often just listening to songs and processing documents while downloading What, and these do not require 100% performance of the computer, then we can also reduce the performance of some CPU, graphics card and other hardware to achieve low-power download.

In fact, the operating system has long noticed the problem of saving energy, providing energy-saving settings, and paying more attention to this aspect in the latest Win7 system. Set the system to a power-saving mode so that you can achieve energy savings.

Click “Start→Control Panel”, find and open “Power Options”, and directly select the energy saving mode in the open window, so that the system can be put into the energy saving mode directly.

In addition, you can also set each hardware item by item in the open settings window by clicking the "Change Plan Settings" item and clicking the "Change Advanced Power Settings" link in the window that opens. But this requires a deep understanding of the computer. Just like the leaving mode mentioned above, the network card and hard disk cannot save energy, preventing downloading from being performed, and sound cards, graphics cards, monitors, other peripherals, etc. can be directly set to the energy saving mode.

Power saving analysis: download in normal mode, if the CPU power consumption is 101W, and after entering the Windows7 energy-saving mode, in the case of ensuring normal downloading, the CPU power consumption only needs 73W, only the CPU can Energy saving is 28W, and there are power consumption savings of other devices. Therefore, when downloading, you can directly put the system into the energy-saving mode, which is also relatively power-saving.

In addition, many CPUs, motherboards and other hardware now provide energy-saving features, such as Intel's EIST, AMD's Cool'n'QuIEt "cool and quiet", ASUS EPU smart energy-saving engine, etc., they can automatically Detects the performance required by the application and adjusts the voltage and frequency of the hardware in real time to achieve energy savings. All the user has to do is turn on the corresponding power saving option in the motherboard BiOS or the included software.

There are still many ways to save energy by downloading, such as setting the automatic shutdown time in the download software, thus reducing the running time of the computer; increasing the download bandwidth of the software, speeding up the download speed; and using offline downloading to reduce the download time, etc. , are all good ways to change energy. You can use them in a reasonable way to achieve optimal energy savings.
