Anyone know about subj.? I have a VGN-SZ770N laptop and would like to know if I could tweak this computer in a better way. Yes, you're right, I could just find info about the chipsets etc..

Thanks.

It looks interesting. I'll try it out and give a status report of my experience afterwards. The fan is running all the time, hopefully your tuning guide will fix that.

Thanks.

You should also load acpi_sony.ko module to get specific to SONY BIOS options:
Code: 
# kldload acpi_sony
# systat -a | grep -i sony

To make it permanent add acpi_sony_load="YES" to /boot/loader.conf file.
 
Hmm, I do what you say, but the fan is still running all the time :-) I have powerd enabled in rc.conf and kldstat shows acpi_sony.ko. PS I can do almost nothing in the BIOS (Phoenix) - the only interesting thing is that I have these choices on TPM: no change, enable, disable and clear. The results below are with "enable".

You will have to issue those commands without being attached to AC, to check time on battery.

This wokrs as you see You mostly are now in C2 state.

Also show me the output of that command: % sysctl -a | grep -i sony

The issue with the fan is a bug in the bios on certain Vaios. I've read about it in official Vaio support forums. I'm using e.g. a Vaio VGN-NS21Z without any problems in FreeBSD 8. The bios in Sony laptops is far from perefct especially if it comes to ACPI.
 
To vermaden: it looks better now. Removed the power supply - the "diff" below shows "after" on the "right".

Code: 
< Remaining capacity:   89%
< Remaining time:       2:55
< Present rate:         19111 mW
< Voltage:              12012 mV

To oliverh: do you have a link to that Sony forum? Im a bit curious. Ive been in contact with Sony Support 3 times (I guess) about the fan problem (running all the time). Its about 6 months ago - everytime they told me that is was normal behavior. In the end I gave up.

To DutchDaemon: "please format your posts"? Not sure what you mean - Im using "code"? Explain please.


Thanks.

Post #5 had no formatting whatsoever. The
