Nowadays, the capacity of high-definition videos is getting larger and larger, often several GB. A high-definition "Avatar" requires 46 GB, not to mention the increasingly popular high-definition TV series. Even if your home uses a 2Mbps broadband network, it will take a long time to download these "big guys". When the concept of environmental protection is strongly promoted by society, those friends who hang up all night to download, please pay attention. For the sake of our green environment, let's also "energy-saving" downloads!
Turn on Windows system away mode to save a quarter of power
If your computer is idle most of the time and is only used for downloading, it would be a waste. At this time, you might as well use "Leave Downloading". Away mode has been added to the WindowVista/Windows7 system. This mode can directly shut down most devices and only retain the normal power supply of some key devices, thus achieving the purpose of saving power.
Unlike the hibernation and standby modes, normal file downloading can be maintained in the away mode, which is equivalent to solving the conflict of having both fish and bear's paw.
1. Activate away mode under WindowsVista/Win7
Although WindowsVista/Windows7 systems come with away mode, it is not activated by default. The activation method is as follows:
Press Win+R, enter "regedit" and press Enter. In the opened registry editor, expand to [HKEY_LOCAL_MACHINE/SYSTEM /CurrentControlSet/Control/sessionManager/Power], and create a new DWord 32-bit named "AwayModeEnabled" under it. item, set its value to 1 and restart. From now on, just click the "Sleep" button in the "Start" menu to enter "Away Mode".
When using Away mode, it is recommended to set the hard disk to never shut down in power management, that is, set "Turn off the hard disk after this time" to "0", set "Turn off the monitor and go to sleep" to "Never", and set "Turn off the hard disk after this time" to "Never". "Wireless Adapter Settings" is set to "Maximum Performance".
2. Grafting away mode in WindowsXP
Download and decompress the "AwayMode" software, import the registry file, then double-click "AwayMode-KB902437-ENU.exe", then run the "Away Mode Chinese Patch" and restart the computer. Open the Power Options in the Control Panel, a "Away" tab will be added, and check "Enable Away Mode".
After enabling away mode, press the sleep key on the keyboard to enter the away mode.
Power saving analysis: We used a power consumption meter to measure the computer power consumption during normal mode downloading and away mode downloading. The power consumption in normal mode was 104W and the power consumption in away mode was 79W. Energy saving rate = (104-79)/104×100%=24.04%.
It can be seen that when simply downloading files, activating the away mode can save about a quarter of the power. If you are an energy-saving supporter, will simple idle downloading still be performed in normal mode?
Let Windows system save "power" by itself
When you usually use a computer, you may not play large games all the time. You often just listen to songs and process documents while downloading. These do not require 100% of the computer's performance. At this time, we can also reduce the The performance of some CPU, graphics card and other hardware can be used to achieve the purpose of low-power downloading.
In fact, the operating system has long noticed the problem of saving power and provided energy-saving settings. In the latest Win7 system, more attention is paid to settings in this area. Set the system to energy-saving mode to save energy.
Click "Start → Control Panel", find and open "Power Options", and directly select the energy-saving mode in the window that opens, so that you can directly put the system into energy-saving mode.
In addition, you can also set each hardware item by item in the settings window that opens by clicking the "Change Plan Settings" item and then clicking the "Change Advanced Power Settings" link in the window that opens, but this requires configuring the computer. It takes a deep understanding. Just like the away mode we mentioned above, network cards and hard disks cannot save energy to prevent downloads from being impossible. However, sound cards, graphics cards, monitors, and other peripherals can be directly set to energy-saving mode.
Power saving analysis: When downloading in normal mode, if the CPU power consumption is 101W, and after entering Windows 7 energy-saving mode, under the condition of ensuring normal downloading, the CPU power consumption is only 73W, and the CPU alone can save 28W, and there are Power consumption savings for other devices. Therefore, when downloading, you can directly put the system into energy-saving mode, which is also more power-saving.
In addition, many CPUs, motherboards and other hardware now provide energy-saving functions, such as Intel's EIST, AMD's Cool'n'Quiet, ASUS's EPU smart energy-saving engine, etc., which can automatically detect According to the required performance, the voltage and frequency of the hardware are adjusted in real time to achieve energy saving. All the user has to do is to turn on the corresponding energy-saving options in the motherboard BIOS or included software.
There are many ways to save downloading energy, such as setting an automatic shutdown time in the downloading software to reduce computer running time; increasing the download bandwidth of the software to speed up downloading; and using offline downloading to reduce downloading time. These are all changing directions. Good way to save energy. You can use them in reasonable combination to achieve the optimal energy-saving effect.
