Windows7 energy saving solution extends notebook life time

The hardware requirements are low and the user interface is more user-friendly. It is the advantage of Windows 7 system, but do you know that Windows 7 has energy-saving effects for notebooks? Because Windows 7 has built-in powerful power management components, it has more optimizations in notebook energy saving than any previous system.

Windows 7 can extend laptop battery life even without installing additional software. Here is a brief introduction to the use of customized power solutions to meet the energy-saving needs of notebook users.

First, use the preset energy-saving scheme

For the notebook, after installing Windows 7, just click the battery icon in the system tray, the “Select Power Plan” window will pop up. It will display the remaining battery life and provide two modes of “balance” and “energy saving”. The default is “balance” mode. If you are using battery and want to get longer battery life, it is recommended to select “energy saving”. "mode.

The author used the Lenovo M10 netbook for comparison test. When using the preset power-saving mode of Lenovo Power Management under Windows XP, the usage time is only 2.5 hours, and when using the preset energy-saving mode built in Windows 7, use The time actually reached 3.5 hours, which proves the energy-saving advantages of Windows 7 built-in power management components. If you want to save energy on the screen, you can choose "Adjust screen brightness", enter "Power Options" and drag the "Screen Brightness" slider (Figure 1).

Second, custom power supply solutions

For business users, it is often necessary to use notebooks in different environments, such as power adapters at home, hope to have the best performance Performance, and when using battery power on the train, I hope that the battery life is the longest. When conducting a PPT demonstration at a business meeting, I hope that energy and performance are balanced. As a result, Windows 7's default power scheme can't meet the demand, but we can customize the corresponding power scheme for different application environments.

The method is to enter the "Power Options" window, click "Create Power Plan", first select a default power plan, such as 3G Internet mobile office, you can select the "energy saving" plan, then enter the plan name, click The "Next" button, then set the details of the plan (Figure 2), for example, under the "Battery" list, set the screen brightness to automatically reduce the brightness within 1 minute to save power, automatically turn off the display after 2 minutes, and After 10 minutes, it will automatically enter the sleep state. At the same time, you can directly adjust the brightness of the display of the plan. After setting, click the “Create” button.

Create different power usage schemes according to the environment that you usually use, such as mobile Internet, office, family games, movies on the hard disk, etc. In actual use, if you need to switch the new power usage scheme, you can click the battery icon in the system tray, and then there will be two power usage schemes. If it is not within the range you selected, you can enter the “Power Options” and then select The corresponding power usage scheme can be used (Figure 3).
