Great find, @zks1! TLP is in the PureOS repository. So many gems are already in the repo for us to discover. I keep finding them. PureOS 9 has TLP 1.1-2, and you can get TLP 1.3.1-2~bpo10+1 if you enable Debian buster-backports (assuming that doesn’t cause any problems in PureOS 9). PureOS 10 will have TLP 1.3.1-2 because that’s what’s in Debian 11 bullseye (unless Purism removed it).
From the TLP documentation:
Version 1.3.1 and lower
- IBM/Lenovo ThinkPads only: start and stop charge threshold, discharge and recalibration
Version 1.4 and higher - additionally:
- ASUS laptops: stop charge threshold
- Huawei MateBooks: start and stop charge threshold
- LG Gram laptops: fixed stop charge threshold at 80% aka battery care limit
- Lenovo laptops (non-ThinkPad series): fixed stop charge threshold at 60% aka battery conservation mode
Samsung laptops: fixed stop charge threshold at 80% aka battery life extenderDisclaimer: all other laptop vendors/brands are not supported.
@nicole.faerber mentioned that the Librem 13 & 15 use an off-the-shelf EC (embedded controller) with proprietary firmware and Purism had to take it or leave it as-is. Maybe it’s the same EC used in one of these other laptops.
Questions for @nicole.faerber :
- Is the EC the same and would TLP work in a Librem 13 or 15?
- Would there be any possible bad effects from installing and running TLP?
