+A note on battery life. Frame.work batteries work best at charges between 80% and 30%. I went into BIOS ([[https://knowledgebase.frame.work/how-do-i-enter-the-bios-on-the-framework-laptop-HydmWf5Ad|pressing F2 on start up]]) and set maximum charge to 90%.

+Suspend worked out of the box. See This PSA from frame.work: [[https://www.reddit.com/r/framework/comments/19bf3ki/linux_suspend_and_amd_reminder/|Linux Suspend and AMD Reminder]]. Per that PSA and [[https://community.frame.work/t/tracking-linux-battery-life-tuning/6665/536|[TRACKING] Linux Battery Life tuning]], I ran [[https://gitlab.freedesktop.org/drm/amd/-/blob/master/scripts/amd_s2idle.py?ref_type=heads|amd_s2idle.py]].

+Enable suspend-then-hibernate. To hibernate, [[https://community.frame.work/t/hibernation-using-it/6060/11|you need swap to be as big as RAM, then update GRUB]]. (32GiB in my case.)
