Reasons for power cycling include having an electronic device reinitialize its set of configuration parameters or recover from an unresponsive state of its mission critical functionality, such as in a crash or hang situation.
Most Internet Service Providers publish a "how-to" on their website showing their customers the correct procedure to power cycle their devices.
[citation needed] Power cycling is a common diagnostic procedure usually performed first when a computer system freezes.

When gentler techniques failed, NASA resorted to rebooting the spacecraft with the remote equivalent of a power cycle.
