TLP allows SATA power management: SATA_LINKPWR_ON_BAT=max_performance There are some old posts that talk about corruption if you enable this with btrfs: https://wiki.archlinux.org/index.php/TLP#Btrfs says not to enable it https://forum.manjaro.org/t/btrfs-corruption-with-tlp/25158 https://github.com/linrunner/TLP/issues/128 says it may not be safe https://www.reddit.com/r/archlinux/comments/5tm5uh/btrfs_and_tlp/ also talks about corruption https://www.reddit.com/r/archlinux/comments/4f5xvh/saving_power_is_the_btrfs_dataloss_warning_still/ say it's probably ok My feeling is that it's probably ok nowadays with a 5.6+ kernel. Would anyone disagree? Thanks, Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R. Home page: http://marc.merlins.org/
