Considering that refreshing memory in sleep/stand-by mode is the main consumer of energy and that soldered memory consumes around 90% less energy (with the obvious caveats, of course) in sleep than non-soldered solutions, this boils down (again, very scientifically measured) to around 0.7/0.8 watts in s2idle, which is a (very) good result, imo. This would be the first laptop with which i’ve been able to achieve acceptable suspend results now that ACPI S3 appears to have gone everywhere.

Still a bit unpredictable with manual suspend where it’ll just decide to wake up instantly for some reason, but once the automatic 15 minute inactivity is hit it seems to sleep with the lid closed. +#+END_QUOTE +[[https://community.frame.work/t/battery-drain-on-suspend-sleep-with-linux/42395/4][Battery Drain on Suspend/Sleep with Linux - Framework Laptop 13 - Framework Community]] +Captured On: [2024-03-03 Sun 06:14] * ArchSetup Complete |
