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?

5 hours watching a video is not that unreasonable for a machine of that age, especially since it's Intel.

According to this review they got 10 hours with wifi off, playing a 720p video that was stored locally on the machine. Youtube is going to have plenty of background tasks going on, wifi is going to be active downloading things, and you've probably got more than just youtube in the background so I would consider 5 hours to be expected without really delving deep into power saving (and probably killing performance).

Alright, I seem to remember someone saying that I could expect 8 hours of battery life, which is why I asked, thank you! Edit: spelling
