There are some black listed products because acpi is broke on them. I seem to remember Which balcklist do you mean? This one? http://acpi.sourceforge.net/documentation/blacklist.html nice find, good info there. One is an HP pavilion zt3030AE and the other one is a Gigabyte 7VT600P-RZ which don't seem to be listed here. these are yours, I think it is time to do some hacking. Acpi is being loaded for you, but it seems you have no thermal support. Check the handbook and the website you mentioned for info about DSDT. You want to do a acpidump, and maybe get the mptable too, then start compiling to check for errors in there code. I think you may find this to be the case. You should forward this thread to the [EMAIL PROTECTED] list and maybe start one at sourceforge. Besure to upload a DSDT too, it may make getting help at sourceforge and that is what they would likily need. some asus products mentioned. Read the handbook about fixing or forcing acpi to load too if it is note black listed. Acpi is on in the bios and being loaded as a module right? `kldstat` shows 'acpi.ko' and `sysctl hw.acpi` shows some stuff. So the acpi module should be loaded. -Hanspeter ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Ideally, it should reduce cpu speed to about 20% when speed is not needed, and restore speed to 100% when the load requires it. There is such a utility for Linux, called powernowd: http://www.deater.net/john/powernowd.html Using this with Debian, my cpu temperature drops by about 15 degrees Celsius! I'm just wondering if a utility similar to powernowd already exists for FreeBSD? I did search the mailing list archives and found some talk about developing just such a program, but never found out if it was finally done, and what the said package might be called. regards, Robert ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" man acpi_thermal and man acpi.
