Re: Fan speed control sony vaio lx800 slimtop
I'm giving up on turning down the slimtop fan for now, the only way I can think of to figure out how Sony is turning down the fan is to boot windows, single step through the installation of the device drivers until I know which one is doing it, and then disassemble it to see what they're up to. If someone has any other ideas let me know. I might hook a scope up to the fan and boot windows just to see if it simply turning the fan down or is varying it. Maybe I'll add a voltage regulator and a few bits of control from the unused printer (it isn't run off the MB) and vary the fan speed brute force. I asked Sony support about the fan issue, they promptly replied that running the fan at high continuosly is fine, that no additional information is available, and that they will "record my interest in alternate operating systems". At least they have a polite way of saying they support nothing but Windows. So I'm going to roll this system back to 4.2 stable and start using it for work. If anyone wants me to try anything out with -current or ACPI then holler today. Two additional ACPI-APM things I did notice: 1. Putting APM into the config caused the keyboard switch to start working to turn the machine on. I'd taken it out at someones suggestion. This is weird, I can only guess APM does something as the machine powers off that ACPI doesn't. 2. Using APM to suspend the machine causes the LED on the power switch to turn amber, using "acpiconf -s 1" doesn't, the machine suspends but the LED stays green. If anyone has any little snippet they want me to try before going back to stable let me know. Anyway, if anyone buys one of these things then rubber bumpers on the base and Dynamat lining the plastic case makes it as quiet as a "normal" computer plus gives it a real solid feel.

Re: Fan speed control sony vaio lx800 slimtop
I'm slightly hoping that enabling an AUTO HALT mode will turn the fan down. I don't think it will, I think I will have to do some subset of what "acpiconf -s 1" does in cpu_idle but will still respond to the next clock interrupt... So my two questions are: 1. Is there an obvious subset of S1 that would be an acceptable replacement for executing HLT and nothing happening in cpu_idle, and, 2. Does anyone understand "AUTO HALT", low power mode, etc on the Pentium III? I found programs (previous message has links) to enable power saving modes on Pentia, but they set a bit in "Model Specific Register 0x12: CTR0", and the Pentium III documentation says "code that accesses registers 11H, 12H, and 13H will generate exceptions on a P6 family processor". (IA-32 Software Developer's Manual, Volume 3: System Programming Guide, Intel order number 245472, page B-25) Peter (The system is reasonably quiet now with my additional sound proofing, but I'm afraid it isn't designed to continously run what was originally an unacceptably noisy fan). -- Peter Dufault ([EMAIL PROTECTED]) Realtime development, Machine control, HD Associates, Inc.

I have a new theory - do we need to enable some sort of suspend on halt for Intel chips? I see we do this for various cyrix chips, and I saw in a search that pentiums with MMX have "auto halt" and "low power on auto halt" options: http://www-student.informatik.uni-bonn.de:8001/~petera/lpp/ Do we enable these?

I'm not sure where that collection is - I don't see it off www.jp.freebsd.org/acpi, if anyone wants to see that .asl file I can put it somewhere public. I also haven't found any "PNP" devices corresponding to an ACPI fan (I forget the exact number) during boot -v. Would I have to do anything special to see it? If anyone has any other ideas of what to do let me know - I'm wondering if throttling down the CPU turns down the fan. In the meantime I've made terrific progress by putting "dynamat" sound absorbing material on the bottom of the plastic drum-like base of the Vaio, it is quieter and now my desk doesn't vibrate when the fan is on high. (www.dynamat.com, new web site in progress) Next I'll open it up and put dynamat on the inside of the plastic - I assume most heat loss is by convection and this won't make much difference. Once I do get the fan throttling working I'll have a real quiet system. Peter -- Peter Dufault ([EMAIL PROTECTED]) Realtime development, Machine control, HD Associates, Inc.

Fan speed control sony vaio lx800 slimtop
I've installed current on a Vaio LX800 slimtop, configured ACPI and can turn the thing on and off with the "power" button. By the way, the 4.2R to -current upgrade was painless. Now I'd like to figure out how to turn the damn fan up and down. This machine is quiet under windows but sets the fan to high under FreeBSD and never turns it down. The fan has three settings - 0V, 6V and 12V. Under windows it stays between 0 and 6V. I've tried "apm -h 1; apm -e 1;" hoping something would happen but it still doesn't slow down the fan. If someone can sketch out a road map of what I should do I'll do the dirty work. I don't know about ACPI etc and so would appreciate a kick start. I've picked up the spec but haven't printed it out yet.
