But charging for just a few percent of capacity having been used up does not make sense. You need tp-smapi-dkms debian package. ThinkPad T520 with 4.16.3 self compiled kernel. Its getting somewhat off-topic here as its not about what the project can do anymore. Well it could provide some defaults, probably. Thanks, -- Martin
