Explain the power options in Windows 7 (1)

Friends who use Thinkpad notebooks know that Power Manager is very powerful, in addition to custom power management solutions, monitor battery usage and control battery charge threshold So even after arriving at Windows 7, many friends are still reluctant to give up Thinkpad's own power management software.

However, you may notice that when we use Power Manager on a system with multi-language packages installed, once the locale is switched, it will be found that the Power Manager's power scheme automatically adds the corresponding language power. The solution, in this way, repeated power management solutions with different languages ​​but the same solution! Very unattractive, this issue Lenovo developers should pay attention to! This issue is still present in the latest version of Power Manager.

How to solve this problem? The normal way to use the power management in the control panel is not to remove the software's own power scheme, but Microsoft provides us with a powerful power management command - Powercfg.exe

Oh Yeh! Refer to the use of Powercfg in Technet Librarys to solve the problem of a repetitive power scheme in Thinkapd Power Manager in disguise, using the command line Powercfg –delete <GUID>. Where <GUID> can be obtained from the command line powercfg –l!

In addition, Powercfg has a number of more advanced command parameters:

The following command line options are available for Powercfg.

powercfg [-l] [-q ] [-x] [-changename] [-duplicatescheme] [-d] [-deletesetting] [- setactive] [-getactivescheme] [-setacvalueindex] [-setdcvalueindex ] [-h] [-a] [-devicequery] [-deviceenablewake] [-devicedisablewake] [-import] [-export] [-lastwake] [-?][-aliases] [- setsecuritydescriptor] [-getsecuritydescriptor]< Br>
