Hi, RE: > > I think "acpi=off apm=on" would be needed to give apm control over power > > management. > Just "acpi=off" works here. Indeed, this i can confirm. With acpi=off, the laptop suspend (or hybernate?) works again. Of course, there is no "acpi", and thus some other features become missing, for example, the CPU speed of the T40 laptop gets stuck at 600MHz, and does not change depending on the presence of the AC input. I will try the stuff from http://www.suspend2.net. Cheers Gaspar
