Hi If APMD locks the system up, it's probably a pretty good bet that ACPI wasn't even heard of when the machine was built. You could probably find out by putting ACPI in your kernel and looking at the output from dmesg, but if your laptop is more than four or five years old there won't be any ACPI on it. ACPI won't help in the case of automatically closing the lid and suspending, anyway, you have to set up linux software suspend for that which doesn't need acpi or apm. However, it's a real pain in the ass to set up, I still don't have it working quite right. Sometimes it works, sometimes I get "unable to handle kernel null pointer dereference" (anyone know what that means, by the way?) If you want to change the behavior of closing the lid with APM, you need to do it from your bios.
