Ok, a little more info...
plugged in
leroy# sysctl hw.acpi.acline
hw.acpi.acline: 1
unplugged
leroy# sysctl hw.acpi.acline
hw.acpi.acline: 0
and from /var/log/messages
Jun 27 07:18:46 leroy power_profile: changed to 'economy'
Jun 27 07:18:57 leroy power_profile: changed to 'performance'
When unplugged the screen dims, the machine seems to slow down, yet heres
the problem...
plugged in
leroy# sysctl dev.cpu.0.freq
dev.cpu.0.freq: 2000
unplugged
leroy# sysctl dev.cpu.0.freq
dev.cpu.0.freq: 2000
I can change the freq using sysctl but it doesn't stick, no crash or
anything though.
Whats odd to me is the temp the cpu is running at.
unplugged
dev.cpu.0.temperature: 54
dev.cpu.1.temperature: 55
plugged in
dev.cpu.0.temperature: 61
dev.cpu.1.temperature: 62
Everything seems to be working as it should, just that pesky cpu freq
Oh by the way, the laptop is a Dell Latitude D820, and I did find out after
testing acpi sleep while X/gnome is running it works! And another side
note... with FreeBSD 7.2 I get approx 2 hours battery life using wifi,
windows gives 1.5 hrs, OpenSolaris 1 hour, have not left the laptop
unplugged with current long enough to test.

Hi all,
I suppose I should state I am only posting after lots of googling.
I upgraded to current from 7.2, I just couldn't wait too see if my laptop
would acpi sleep, it seems to just fine by the way, not well tested yet
though.
My prob is with cpufreq, it seems to be locked at max speed, nothing I do
seems to change the freq it is running at.
CPU: Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz (1997.34-MHz
CPU)
leroy# dmesg | grep cpu
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
cpu0: <ACPI CPU> on acpi0
coretemp0: <CPU On-Die Thermal Sensors> on cpu0
est0: <Enhanced SpeedStep Frequency Control> on cpu0
p4tcc0: <CPU Frequency Thermal Control> on cpu0
cpu1: <ACPI CPU> on acpi0
coretemp1: <CPU On-Die Thermal Sensors> on cpu1
est1: <Enhanced SpeedStep Frequency Control> on cpu1
p4tcc1: <CPU Frequency Thermal Control> on cpu1
It looks to this feeble mind like it should be working.
Where else do I look?
leroy# ps ax | grep powerd
1164 ?? Ss 0:00.97 /usr/sbin/powerd -a adaptive -b adaptive
Hope this is enough info...
Not quite. The output of 'sysctl hw.acpi.acline' (on battery and on AC
power) and 'sysctl dev.apu.0' would help. Running powerd with the '-v'
option might provide a clue, too.
Everything you sent looks pretty normal, but it's not enough to tell much.
