Could some offer a resource to where I can learn the answers to these questions: 1. Is there an active mailing list for APM/ACPI issues? 2. Is ACPI mature now-a-days even thought there seem to be conflicting standards? 3. Like APM, is ACPI compiled into RH 9 kernels by default? (ie, gkrellm tells me my kernel doesn't support ACPI, so I think the answer is "no".) 4. Can I totally do away with APM and use ACPI? Or is ACPI dependant upon APM? 5. What are some tricks I can do with APM/ACPI to prove things are working? Another vaio laptop users said he enabled ACPI "resulting in significant heat and power use reduction". Thanks, -eric wood
