QuickStart and Deeper Sleep

QuickStart and Deeper Sleep are two processor features appearing in some Intel processors.

Intel's description

QuickStart extends battery life by reducing power during pauses in user activity, such as between keystrokes.

Deeper Sleep alert state is a dynamic power management mode which is enabled during less than a millisecond of inactivity by the user, such as between keystrokes, delivering longer battery life


This is one of the earlier C-State implementations, which was discarded/renamed in more recent processors.

Deeper Sleep

This is most commonly the last and deepest sleep-state available, but in fact its implementation was changed almost anytime in a new processor, just the names stays the same.
