The hardware requirements are low and the user interface is more user-friendly. The advantages 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.
even without installing additional software, Windows7 system can extend laptop battery life. Here is a brief introduction to the use of customized power solutions to meet the energy-saving needs of notebook users.
First, using a preset energy-saving scheme for notebook
in Bahrain Windows7, simply click the battery icon in the system tray, it will pop up "Select a power plan" window, this time 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. I
M10 association with the Internet comparison test, using the predictive power management at the preset power saving mode WindowsXP, usage time of only 2.5 hours, and in the use of the built-in Windows7 preset power saving mode, the time actually used It took 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, the customized power scheme
For business users, often need to use the notebook in a different environment, such as at home with power adapter, want to have the best performance, while When using battery power on a train, I hope that the battery life will be the longest. When I conduct a PPT demonstration at a business meeting, I hope that energy and performance will be 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.
by going to the "Power Options" window, click "Create a power plan", first select a default power plan, for example, when the Internet 3G Mobile Office, you can select the "energy" program, and then enter the program 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.
according to several frequently used their usual environment, to create a different power scheme can be, for example, mobile Internet, office work, family games, train hard in terms of movies. 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).
