Usage notes[edit]
Phrasal verbs with the particles down and up tend to connote a process that takes a span of time and contains multiple steps, whereas those with the particles off and on tend to connote an event that happens instantly, in a point of time. This nuance of cognitive schema is merely connotative, not denotative or rigorous, and therefore the phrasal verbs shut down and power down are broadly synonymous with shut off, power off, and turn off, as well as stop and kill. However, the fact that turning a computer on or off requires booting and unwinding, which are multistep processes (albeit black boxes to the user in modern operating systems), influenced the origins of power management commands such as shut down rather than turn off or switch off. Similarly, power plants and ship engines are fired up and shut down, and not so much turned on and switched off, in idiomatic usage. Nonetheless, any process (no matter how complex) can be triggered with a single command, which is why an executive officer or legislature can simply kill a multi-billion-dollar government program, or a laptop user can simply switch off their computer, even if the program takes a while to wind down.
