Ways to save power by making Windows 7 more energy efficient

Today's high-definition video capacity is more and more large, a few gigabytes, more than a high-definition "Avatar" will be 46GB, not to mention the increasingly hot High-definition series. Even if your home is 2Mbps broadband network, it will take a long time to download these "big guys". In the concept of environmental protection is strongly advocated by the community, those who hung up all night to download friends attention, for our green environment, so that download also "energy-saving" bar!

Open windows system leaving mode, saving One-fourth

If your computer most of the time is idle, just to download, it is very wasteful, then it may be useful to use the "leave the download." In the Windows VISTA/7 system has added the departure mode, this mode can directly close most of the equipment and only some key equipment to retain the normal power supply, and thus achieve the purpose of saving energy.

and hibernate, Standby mode is not the same, in the departure mode can keep the normal file download, which is equivalent to solve the fish and bear bear cannot be both contradictions.

1. Windows VISTA/7 To activate the left mode

The activation method is as follows in the Windows VISTA/7 system, although it has its own leave mode, but is not activated by default:

Press Win+r, type "regedit" and enter, and expand to [Hkey_local_machinesystemcurrentcontrolsetcontrolsession Managerpower] in the Open Registry Editor, Under it, create a new DWORD 32-bit item named "Awaymodeenabled" and set its value to 1 restart. In the future, just click the Sleep button on the Start menu to go to leave mode.

When using leave mode, it is recommended that the hard drive be set to never close in power management, that is, "turn off the hard drive after this time" set to "0", set the "Turn off monitor to sleep" setting to "never" and set "Wireless adapter Settings" to "highest performance".

2. Grafting departure mode in Windows XP

Download Decompression "Awaymode" software, import the registry file, and then double-click "Awaymode-kb902437-enu.exe", and then run "Leave mode Chinese patch", restart the computer. In the Control Panel, open the Power option, which adds a "Leave" tab, check "Enable leave mode" (Figure 1).

When you enable leave mode, and then press the Hibernate key on your keyboard, the system goes out of mode.

Power Analysis: We use the power meter to download the normal mode and leave the mode of downloading the computer power consumption is measured, in the normal mode of power consumption of 104W, leaving mode under the power consumption of 79W. Energy-saving rate = (104-79)/104x100%=24.04%.

It can be concluded that in a simple download file, the start of the departure mode will save about One-fourth of the electricity. If you are an energy-saving supporter, can the simple hanging machine download still in normal mode?

Let Windows system itself Thrifty section "Electricity"

When using the computer in peacetime, you may not always play a big game, often just download while listening to songs, processing documents and so on, and these do not require the performance of the computer 100%, then we can also reduce some CPU, graphics and other hardware performance, to achieve low power download purposes.

In fact, the operating system has long noted the problem of saving energy, providing energy-saving settings, in the latest Windows 7 system to pay more attention to this aspect of the settings. Set the system to energy-saving mode, so that energy-saving purposes can be achieved.

Click start → control Panel, locate and turn on power options, and select the energy-saving mode directly in the open window so that you can put the system directly into energy-saving mode (Figure 2).

You can also click the Change advanced power settings link in an open window and click on the "Change Advance" button in the Open Settings window to set each hardware one by one, but this requires a deep understanding of the computer. Like the above we mentioned the departure mode, the network card, hard disk can not be energy-saving, to prevent the download can not be carried out, and like sound card, graphics, monitors, other peripherals, and so could be directly set into energy-saving mode.

Power analysis: In the normal mode of downloading, if the CPU power consumption of 101W, and into the Windows 7 energy-saving mode, in ensuring the normal download, CPU power consumption only need 73W, only CPU can save energy 28W, and other equipment power savings. Therefore, in the download, you can directly let the system into the energy-saving mode, which is relatively provincial power.

In addition, now many CPUs, motherboards, etc. 9 7 3 1 2 4 8:

Hardware provides energy-saving features such as Intel's EiST, AMD's cool ' n ' Quiet, and Asus ' EPU Intelligent Energy-saving engine, which automatically detects the performance required by the application and adjusts the voltage and frequency of the hardware in real time to achieve energy savings. The user has to do is to open the appropriate energy-saving options in the motherboard BIOS or accompanying software.

There are many ways to download energy saving, such as setting the automatic shutdown time in the download software, thus reducing the running time of the computer, increasing the downloading bandwidth of the software, speeding up the download speed, and using offline downloading, reducing download time, etc., are all the ways to save energy. We can use them rationally and achieve the optimal energy-saving effect.
