My comment:

An application may use SetSuspendState to transition the system from the working state to the standby (sleep), or optionally, hibernate (S4) state. This function is similar to the SetSystemPowerState function. The calling process must have the SE_SHUTDOWN_NAME privilege.

To prevent the user from putting the computer in standby mode, the application must deny the PBT_APMQUERYSUSPEND event.
