It almost sounds like an ACPI _PPC change notification issue. I am not positive, but I think Solaris supported _PPC change notifications before 2008.11?
The cpu_info kstat will show the supported p-state frequencies. It might be interesting to see what frequencies are available in the two different power (battery) modes with: # kstat cpu_info | grep supported_frequencies_Hz Regards, Bill On 10/08/08 13:12, Eric Saxe wrote: > How about PowerTOP?
