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?

    Oddly the laptop seems brand new when I got it, it still had the peel on the power button lmao. Also, thanks for the tips!

      There’s software to check how many mAh most laptop batteres are able to take up and deliver, compared to what they shipped with. Modern ones even have how many complete 0-100 charge cycluses the battery have gone through. You can check if you think there’s something dodgy about the battery. I’ve actually seen laptops factory shipped with smaller batteries than ordered.

      But knowing linux and seeing you had an issue with the power profiles I’d think it’s software related hah. Is there a discrete GPU onboard it’s using instead of the power-saving one perhpas?. Also, did you turn off that awful “dynamic background” on youtube that continually taxes the CPU?
