First of all, thank you for answering. :-) The cable is plugged to a multiple socket that has and interrupter. I cut the energy from there while doing the tests, mainly because I'm interested it work in that way. I'm not an electricity expert but I think I understand why you're asking that question. If the AC cable is connected to the laptop, even when in the other end it's not connected to the source, since the converter holds some residual voltage could make the laptop think it's still connected to the main source, right? But when the source is cut (in the way I explained above,) apm(4) correctly says the AC power is "disconnected," that's why I assumed apmd(8) should not be tricked by the converter. > > Edgar > > > > > Curious because power management seems to work fine in my T410.
