Environmental protection starts from the computer Power saving has a coup

Energy saving and emission reduction is not just a matter of car. Now computers also need energy conservation to make a contribution to environmental protection. Computer energy conservation is mainly about saving electricity. Nowadays, the HD video capacity is getting bigger and bigger, and a few GB, more than one HD "Avatar" will be 46GB, not to mention the increasingly hot HD series. Even if you are using a 2Mbps broadband network, it will take 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 download also “energy saving”.

Turn on the Windows system to leave the mode, save power four One of the

If your computer is idle for most of the time, just for downloading, it is very wasteful. At this time, you may wish to use “ leave the download & rdquo;. In the Windows Vista/7 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.

And 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 the exit mode under Windows Vista/7

Although the leave mode is included in the Windows Vista/7 system, it is not activated by default. The activation method is as follows:

Press Win+R, enter “regedit” and press Enter. In the open registry editor, expand to [ HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlsession ManagerPower] and create a new DWord 32-bit entry named "AwayModeEnabled" under it. Set its value to 1 to restart. In the future, just click the “sleep” button in the “Start” menu to enter “ leave 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”; set to ““0”, “will close the display and enter Sleep & rdquo; set to “ never & rdquo;, & ldquo; wireless adapter settings & rdquo; set to & ldquo; highest performance & rdquo;.

2. Grafting away mode in Windows xp

Download and unzip the AwayMode” software, import the registry file, and then double-click "AwayMode-KB902437-ENU.exe" to run & nbsp; Leave the pattern finished patch & rdquo;, 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 enters the exit mode.

Power Analysis: We used the power 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 leave mode. Energy saving rate = (104-79) /104 & times; 100% = 24.04%.

As you can see, when you simply download a file, starting the exit mode saves about a quarter of the power. If you are an energy-saving supporter, will pure hang-up downloads still work in normal mode?
