hmmm, I don't think that powernowd cares about battery status (it adjusts cpufreq based on load). Are you using powernowd, or some other frequency adjusting tool? You can adjust the scaling profile by editting /etc/default/powernowd As a side note, on my amd64 laptop (Compaq R3190), the frequency tables in the bios are bogus. I needed to choose the kernel option CONFIG_X86_ACPI_CPUFREQ in order to allow the kernel to use ACPI to retrieve the frequency info (this is how Windows does it). Of course, if it already works when using wall power, then I doubt that this is an issue for you... -Ted -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
