Hi, Reporting another issue on BETA4, powerd isn't adapting the cpu frequency at all on my system - running it with -v shows that it selects APM, and then sits doing nothing. If if would check AC status via hw.acpi.battery.state (2=AC power 1=battery), (at least on) this system it would work::: From powerd.c: #define ACPIAC "hw.acpi.acline" (...) if (sysctlnametomib(ACPIAC, acline_mib, &len) == 0) { hw.acpi.acline does not exist (on this system, at least) but hw.acpi.battery.state does, and is immediatly changed as soon as I plug/unplug ac power. Best regards, Hugo
