CA1601: Do not use timers that prevent power state changes
A timer has an interval set to occur more than one time per second.
Do not poll more often than one time per second or use timers that occur more frequently than one time per second. Higher-frequency periodic activity will keep the CPU busy and interfere with power-saving idle timers that turn off the display and hard disks.
Set timer intervals to occur less than one time per second.
This rule should be suppressed only if firing the timer more than one time per second is required and mobility considerations can safely be ignored.
