I clearly remember that Henrique de Moraes Holschuh (cc:ed, ThinkPad-ACPI upstream maintainer) told me at DebConf9 that is there actually a way to "bare metal" manually charge dead ThinkPad batteries if the EC controller is not dead (technical details may be wrong, but you got the idea). I have never tried looked for the necessary information nor tried that, but I will certainly to that. Links appreciated ;-) Thx, bye, Gismo / Luca
