How to make Win7 system laptop batteries longer

Battery use time is short, this is in the use of notebook friends are more dissatisfied with the place, but we can use the Win7 system in the energy-saving settings to extend the use of battery time, then how can we set the Win7 to make the notebook battery use time longer? Here are a few scenarios you can refer to.

Scheme I, Win7 system preset energy-saving program;

Windows7 built-in very good power management mechanism, and preset several power management solutions to meet the user's basic energy-saving requirements, such as battery-powered, you can click the taskbar's battery icon, and then select the "Energy saving" option, so that the system will automatically enter a low-power mode, to help users save battery power. The following figure:

As shown in the figure above, we can choose the "Energy saving" scheme

After choosing a preset energy saving scheme, we can also fine-tune the settings to adapt to their own notebooks, for older notebooks, because the display using CCFL backlight, power consumption is relatively large, we can properly reduce the screen brightness to save battery loss, the method is to click "Adjust screen brightness", Then adjust the brightness slider to the left as needed (Figure 2), after testing, the brightness adjustment to 60%, without affecting the use of the situation, you can save about 18% of the battery power, of course, the specific regulation to much does not matter brightness still have to according to personal preferences, can not be used to power-saving eyesight ruined.

Plan II, personalized energy-saving program

For the special crowd, Win7 preset energy-saving solutions if you do not meet your needs, at this time we can customize to set the system, by entering the "Power Options", enter the "plan name" (such as 3G Internet), and then click the "Next" button.

Figure 3 Custom Energy Saving scenarios

In the "Battery" list (see Figure 4), set a minute to automatically reduce the screen brightness http://www.xitonghe.com, two minutes after automatically turn off the display, in five minutes automatically into hibernation, while reducing the screen brightness value, and click the "Create" button, So when we do 3G Internet, the system will follow your preset to perform energy saving settings.

Plan III, custom Advanced energy-saving program

For the absolute control of energy efficiency, Win7 system is rich in the provision of each part of the settings, you can adjust each part according to their own needs, by selecting the "3G Online" program, click "Change Advanced Power Settings", and then the energy-saving settings for each part, such as expand the "Wireless adapter settings" under the " Energy-saving mode, "use Battery" set to "low energy" mode or when not using USB, we can let the system automatically prohibit the use of USB components to reduce the power supply and achieve the effect of electricity saving.

In addition, we can also target graphics, CPU ' hard disk and other standby devices to set up, such as "Processor power management", the "minimum processor state" of the use of the battery set to "100%" (Figure 6), so that the CPU will always work in low power mode, according to the test, reasonable energy-saving scheme, This will allow the savings to increase nearly 1-hour endurance.

These schemes can make the Win7 system notebook battery More time to use, reasonable for their own notebook use energy-saving can not only improve the use of batteries, but also to lift the life of the battery.
