Detailed explanation of power options in Windows 7

Friends who use the Thinkpad pen power know that their power Manager is very powerful and can monitor battery usage and control battery charge thresholds in addition to the ability to customize the source management solution, so even with Windows 7, many friends will not want to abandon the Thinkpad own power management software.

However, you may notice that when we use Power Manager in a system with a multilanguage pack, once we switch to the language environment, we will find that it is automatically added to the power scheme for the corresponding language, so that it will return Now a different language but the same scheme of power management program! Very unattractive, this question the developer of Lenovo should pay attention to! The issue is still in the latest version of power Manager in time.

How do you solve the problem? The normal way to use power management in Control Panel is to not remove the software's own power scheme, but Microsoft provides us with a powerful power management command-powercfg.exe

Oh yeh! Refer to the usage of Powercfg in Technet librarys, which resolves the problem of a duplicate power scheme in THINKAPD, using command line Powercfg–delete <GUID>. Where <GUID> can be obtained via command line POWERCFG–L!

In addition, POWERCFG has many more advanced command parameters:

The following command-line options are available for Powercfg.

powercfg [-l] [-Q] [-X] [-changename] [-duplicatescheme] [-d] [-deletesetting] [-setactive] [-getactivescheme] [-SETACVA Lueindex] [-setdcvalueindex] [-h] [a] [-devicequery] [-deviceenablewake] [-devicedisablewake] [-import] [-export] [- Lastwake] [-?] [-aliases] [-SetSecurityDescriptor] [-getsecuritydescriptor]
