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.

Low battery life due to high power consumption on t490 thinkpad. (help needed) (lemmy.zip)

So i have gotten a t490 just recently, and ive installed fedora on it, gnome power profiles daemon said it was "on my lap" and wouldn't let me change the power profiles even when on a desk. So i masked that, and installed auto-cpufreq, but the laptop still draws about 10W (according to powertop) when watching a youtube video, leading to 4-5 hours of battery life.

any tips on how to reduce the power consumption?

While I think that 5h of battery life with yt videos running is ok for a t490 you could still try to recalibrate the battery with tlp.

I have a t470s (has two internal batteries) where suddenly the performance of one of the batteries somehow got really bad. After calibration it works as good as before (upower says it's at about 80%). I did the calibration in windows tho with Lenovo vantage as I'm still running a dual boot setup and didn't know about tlp before.
