Power Sleep Symbol

Represented by a solid crescent moon, the Power Sleep Symbol is a graphic icon used to indicate a standby or low-power state for electronic hardware. It belongs to the Miscellaneous Technical block and is classified as a common script character used globally in user interface design. While it functions as a functional icon rather than a phonetic letter, it is generally referred to simply as the sleep or standby symbol.

In practical application, this character is most frequently encountered in tech and UI contexts, such as on physical power buttons or within computer operating system menus. It serves as a clear visual shorthand in digital documentation to instruct users on how to enter power-saving modes. Outside of technical manuals, the symbol is occasionally repurposed in social media posts or digital messaging to represent rest, nighttime, or the end of a session.
