Power Management for a limited user

[kap4lin]

As a limited user, I can not choose/set the power management option! The limited user is bound by whatever the Administrator has setup. For example, if the Administrator has setup for "Max. Battery", I can not change it to "Presentation". I am looking for a software which will give the limited user the ability to change the powermanagement option without having to log in as an Administrator. Any help?

Thanks, in advance.
