Collocations and Patterns

  • 开机 (turn on a device): Used for powering on electronics.
  • 开机速度 (startup speed): Refers to how fast a device powers on.
  • 开机密码 (startup password): The password required after powering on.

Notes

"开机" is a verb-object compound and is informal but widely used in everyday speech. It differs from "启动" (qǐdòng), which can mean "start" or "launch" in a broader sense, including software or processes. "开机" specifically refers to powering on hardware.

Avoid confusing "开机" with "" (open the door), as "" here refers to a machine, not a physical door or desk.
