Interestingly, switching to TLP didn't lower power usage by more than maybe 1 Watt in either distro (compared to power-profiles-daemon) on my machine. Fedora Rawhide got as low as 13.7W, but Krypton only got as low as 24.0W. The CPU in this laptop is an AMD Ryzen 7 6800HS Creator Edition, and the dedicated GPU is an Nvidia RTX 3050 Mobile (but the built-in display is connected to the AMD integrated GPU).
