When you select the target computers, be mindful that only one power scheme can be active on a computer at a time. When you run more than one Power Scheme Task on a target computer, the task that runs last sets the active power scheme. For example, you may run the Always On Power Scheme task on all your computers. Later, you can run the Portable/Laptop Power Scheme task on your notebook computers.
The power scheme that the specified Power Scheme Task creates and activates, is always named Altiris Power Scheme on the target computers. For example, when you run Always On Power Scheme task, the created and activated power scheme is named Altiris Power Scheme on the target computers.
