From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Your CPU never actually sleeps, it stays in S0 (on). The CPU is still active and doing things, but it's in a "low power state".
In quotes because it's not low power at all. On one of my laptops S0 standby gets worse battery life than just actually being on.
Speak for your own cpu. Mine definitely takes naps every time I try open Firefox
