That line quoted, but the rest didn't.  gmail can be weird, but so can

I changed my */etc/rc.conf* from

performance_cx_lowest="CMAX"
performance_cx_lowest="CMAX"

to

performance_cx_lowest="Cmax"

and I rebooted laptop.

Returns from performance to economy profile when I plug / unplug the charger

I restart powerd service to keep the latest values.

Right, so you should get ~4 hours from a full charge (at idle, anyway)

Mildly surprising only one thermal zone, and that with no passive 
cooling potential, but I suppose it relies on the fan.

Now for the script, I have a little problem

The script now:

#!/bin/sh
t="     "       # a tab
echo -n "`date` "
sysctl dev.cpu.0.freq
echo "`sysctl -n dev.cpu.2.cx_usage` $t `sysctl -n vm.loadavg`"
echo "`sysctl -n dev.cpu.7.cx_usage` $t { `sysctl -n kern.eventtimer.timer` }"
sysctl dev.acpi_ibm | egrep 'fan_|thermal'
sysctl hw.acpi.thermal.tz0.temperature
acpiconf -i0 | egrep 'State|Remain|Present|Volt'

And

*sudo kldload acpi_ibm*
Password:
kldload: can't load acpi_ibm: module already loaded or in kernel

but

Again, looking good for ~4 hours at idle.  If you get the video stuff 
sorted out - I know next to nothing about that - might save some more.

I've no idea what's wrong with acpi_ibm here.  I suppose that
 # kldstat -v | grep ibm
produces no output?  Maybe it doesn't work with this model?  Anyone?

English. I learned alone through FreeBSD forum!

Wouldn't dream of it.  You're doing fine.

Not top-posting - M$ outlock style - would be a nice touch though :)

cheers, Ian
