Win7 system how to set the most power-saving computer

In order to improve the battery life of the notebook, in addition to using a battery with better performance and quality, using the power management that comes with the Win7 system can also save power for the notebook. However, in the Win7 switch power scheme, you must first enter the control panel, the operation is somewhat troublesome, and there are no convenient shortcut keys available, so most users have not used this function. Today, I will teach you a good way to quickly switch Win7 power solutions. Just set our usual power management scheme to desktop shortcuts. Just use one of them and just double click it. First run "powercfg-list" using the CMD command line to list the power management schemes that have been configured in the current system.
View all power scheme GUID
Next right click on the blank space of the desktop, select "New-Shortcut", in the "object location" option, enter "C:WindowsSystem32powercfg.exe" ;, click Next, and name it "Energy" to complete the creation of the shortcut.
Create a shortcut
Now this shortcut can't be switched yet, we need to set it up again. Right-click on the shortcut, open the "Properties" dialog, switch to the "Shortcuts" tab, and change the "target" content to "powercfgsetactiveGUID" format, where the GUID needs to be changed to the corresponding code.
According to the previous CMD running "powercfg-list" command line display results,
replaces "GUID" with the corresponding code found from the CMD command line,
including balance, high performance, Three modes of energy saving. Here we create the "energy" shortcut, so change the target of the shortcut attribute to "
powercfgsetactivea1841308-3541-4fab-bc81-f71556f20b4a".
Modify the shortcut target
Use the same method to create several other power solutions in Win7 as desktop shortcuts. When you need to switch, just like opening the application, double-click the desktop icon to get the Win7 notebook. Quickly switch to the corresponding program.
