PureOS team to investigate SATA Linux Power Management for laptops;
- Does PureOS have SATA Link Power Management enabled by default?
- How do we add 'med_power_with_dipm' as default for at least Mini and laptops? Via Udev?
- We could opt in via udev if we don't trust having it enabled for all devices but according to @nicole it boosts battery life considerably (it sure does on other harware i own)
- Enabling SATA Link Power Management can and most likely will save 1W+ (if they have a SATA SSD installed) which can result in 1h or more battery runtime.
SATA Link Power Management can be enabled via sysfs
and Guido suggested to use the safe mode
