Yes, the sysctl included "throttle". As I said, I'm new to the laptop world.. Is the power saving difference a lot if I just throttle the clock, instead of using enhanced speed step? > > [Enhanced] Speed Step reduces the clock speed and the CPU core voltage.. > clock > throttling just idles the CPU for a certain proportion of the time.

He had /proc/acpi but no /proc/acpi/battery. I know battery status can be seen, as the laptop shipped with win XP home, which I promptly got rid of, but I installed a game there to see how many FPS I'd get playing with the laptop. So I still messed around with it (windows) for around 35 minutes, and could see the little battery icon discharging. If the acpi_cmbat0/1 shows up on dmesg, what could be wrong? Perhaps this ACPI implementation is a bit weird and I should send a copy of my asl to freebsd-acpi ? > > -- > Daniel O'Connor software and network engineer > for Genesis Software - http://www.gsoft.com.au > "The nice thing about standards is that there > are so many of them to choose from." > -- Andrew Tanenbaum > GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C >
