This delegate defines the signature that an event handler must use to receive the SystemEvents.PowerModeChanged event. This event is raised when the computer enters or exits suspend mode, and when the power consumption level changes. A computer requires Advanced Power Management (APM) or Advanced Configuration and Power Interface (ACPI) support in order to use these operating system features. APM/ACPI is usually supported on (but not restricted to) portable computers and devices.
