Could you clear up for me what "currently" means in this context? I don't know what code was changed in January or so -- only that the change led to incorrect reports, on a Thinkpad T400s with two batteries inserted. > The way they handle multiple batteries is by merging multiple data into > a single report. I am not sure what that means, concretely. Is this what you mean by "proper" support, Proper support means at least giving a good estimate for how long before the machine runs out of energy, and a good estimate of the actual fraction of maximum charge the batteries can hold. The code from last October could do that. When I type M-x battery in the version as of October 2, it displays something like Power BAT, battery Discharging (98.1% load, remaining time 4:04) where the numbers depend on the energy capacity of each battery and the current charge of each battery, as well as the actual current or power. That is what I think is crucial for M-x battery. -- Dr Richard Stallman Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
