You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure. 

To open Device Manager, click Start, and then click Control Panel. Click Performance and Maintenance, and then click System. On the Hardware tab, click Device Manager

You can use the power management settings to specify that the operating system come out of a low-power state to service an event. For example, an incoming modem call will alert the system to service the call even if the system is in hibernation. You can also specify whether the operating system should turn off a particular device if it is not doing something, such as servicing a call.

The Power Management tab only appears for device drivers that support the power management standards, such as network adapters.

If you are not an administrator or a member of the Administrators group, you can use Run as to perform certain administrator functions. For more information on how to use Run as, see Related Topics.
