Right, it's because the Compaq wants to do a 'standby' instead of a supsend for some reason...??? > It turns out that PAO has a solution for this using the > APM_NOSUSPEND_IMMEDIATE option. It turns out that PAO has a hack for this, instead of a solution. A hack is better than nothing, but a solution is better than both. I'd like to see someone implement a solution to the problem rather than adding 'yet another' option for laptops. There are already too many options to keep track of, so we need to find solutions so that FreeBSD works 'out of the box' well on all laptops, and solutions to one laptop don't negatively affect another laptop. > By the way, I had first tried out PAO; I thought it was > required to get pccards to work.

Great, glad to hear it. > Is there some advantage (laptop wise) that warrants > upgrading to 2.2.5-RELEASE? No, but 2.2.5-STABLE contains alot of new fixes for suspend/resume. Suspend/resume works much better now, although there are still a couple of minor (known) bugs in the support which I'm working on. Nate
