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.

This is what's important. If you don't enable power saving in some fashion, your hardware will always be "on" at full specs. Even if the machine isn't actually being used, it's still powering everything to be ready to jump at any opportunity to process something quickly without ramping down.
TLP has pretty excellent default settings. Simply turning it on will likely make your battery life go 2-3x longer than without it being on, and you will have about 80% of the performance from a UX perspective. And if you want to crunch numbers faster on battery, you can tune TLP or turn it off temporarily.
Thanks to you I just found out that I DID enable wake-on-lan a year ago and that there's another reason I couldn't do it.
