Re: [S10/S10e Fan Problems Collecting Info for Lenovo] S10 fan runs too fast, too often, too loud

Fan behaviour changed definitely!



 

Yes! Fan behaviour now is *sensibly* different for us Linux users. I confirm the >10C difference in ACPI temperature readings from previous version. Also the granularity changed from 3 degrees to 1 degree.

 

And, of course, the much more tolerable on/off cycle.

 

There is still some oddness (sometimes the reported temperature doesn't correlate well with the fan behaviour), but a step in the right direction imho.

 

thanks

BIOS 66 on S10e

Fan works longer and with the same intensity.

The worst thing is that the ACPI control on NHC does not work anymore.

 

@carsten

Is it something that can be done? If yes, please detail as for an ignorant like me.

@Danmarc

NHC works again, but I'm trying to get the temperature difference under control (so that NHC displays the same values as Core Temp and so on). But one good thing: That sometimes on-off-cycle of the fan seems to be gone...

 

Who wants to do it right now: open S10e.cs in notepad, replace every 0x51 by 0x50 and change the thresholds in NHC from 55/40 to 65/55. The shown cpu temperature is defenitively wrong.

Re: [S10/S10e Fan Problems Collecting Info for Lenovo] S10 fan runs too fast, too often, too loud

My experience with s10e and Bios 66: NO CHANGE at all! The advertised “(fix) Thermal table for fix FAN noise issue.“ is hardly a “fix”. For me it is still a wish.

I was checking this thread since almost its first days among the living. So no one can say I am impatient. Unfortunately my patience has almost dried out until now and today I broke down and registered in order to give my contribution to the growing page numbers of the thread. I bought my s10e in the first weeks of January with the intention to use it as an eBook Reader in the library. Ironically I was waiting for it since July 2008 (!!!) to become available here in Germany. Now selling it on eBay would be really sad. Because I really love it. BESIDES THE F**** FAN!

I am asking myself: How am I supposed to sit there and try to read (in the library), while this VACUM CLEANER is drilling my ears, and the ears of the people in a 6 meter radius around me. And in a library that's a lot of people!

I use IBM/Lenovo laptops since the year 1999 and was always happy with them. I always buy IBM/Lenovo laptops for my family. I have always thought when it comes to laptops, there are only two brands out there which I would buy. That was Sony and IBM/Lenovo. And Apple of course, but that's of the road. After that issue I really don't think I will buy Lenovo any more. So I guess it's only Sony and Apple. Unfortunately Sony's netbook is ridiculously expensive, and the display is too small. And I really don't like the other netbooks, I've seen them all and I want THIS one! I really can't understand how can this happen. I am also doing some programming myself, and just can't imagine why are those guys taking so long. It is a bios for god sake. Implementing a fan control bios setting should be a piece of cake! It's not like having to write a 60+ million Lines of Code Operating system! If there is a hardware issue just put some extra options there like having the user to decide which temperatures would turn the fan on, and what rpm level should it be. This is not more than 200 Lines. It can be done by a single person for a day. With the testing!!!

Or here's another idea. If there is a hardware issue take all those netbooks for service and repair them! :) (I know that's not going to happen) OR let the users themselves repair it, and make a statement, that the warranty won't be void, if an user opens his netbook in order for fan/heatsink/pad exchange.

The only positive thing from the BIOS 66 is that now the Fan Control Program works (if you don’t change the setting in the config file as explained in the post 777, but leave it 80 - like it is, just like for the s10) For that I really want to thank dresslerc. You did a great job man!

One question at the end: Did anyone notice the flood of warnings in the event viewer resulting from the fan control program? It’s not like it’s as painful as the noisy fan, but it gets full really fast, and looking for a real error would be a hard thing to do.

 

P.S. Sorry for the long post, but I was really frustrated!

@Carsten

Thank you for the prompt answer. 

I did the modification from 0X51 to 0X50 in the S10e.cs file but the acpi still does not control the fan like it did.

If you have time, maybe you can post the modified cs file. because I am affraid to do something wrong.

 

Thanks.

Did you restart NHC? Changes in the profiles only work after NHC is restarted. NHC compiles the cs to a dll on startup.

You were right. Now it works.

But with a significant delay when initialize. With BIOS 57, when I checked the ACPI control system, the fan stopped immediately. Now it takes some time.

Anyway, is good that it works.

And the difference with the CoreTemp increased.

 

Thanks.

One of the S10 bios updates not too long ago also changed the indicated CPU temp by 12 to 13 degrees. Based off the air temp coming out the exhaust port I would say the new temps are correct and the original ones were showing low.

I've just updated to the 66 BIOS, as far as I can see there isn't much to shout from the rooftops about.

 

Fan seems to be on for longer, at a lower speed. Isn't this what people have been asking Lenovo from day one?! lol :smileyvery-happy: I haven't fully tested the fan responce to a bit of hard work, but it seems to be a step in the right direction. Believe it or not I never thought the fan was terrible, just a little louder than justifiable for a machine of this type.

 

Still can't believe it has taken this long, and this many posts, to get movement on the fan noise issue though.

Re: [S10/S10e Fan Problems Collecting Info for Lenovo] S10 fan runs too fast, too often, too loud

S10e/4187-2NU, BIOS flashed 57->66, WinXP SP3 (+ Splashtop & WUBI)

 

Fan behavior is definitely changed:  Runs continuously on Splashtop, runs a bit during boot, stops running on WinXP start.

Kicks in at ~60C, off under 55C.  Does not "hunt". Does not seem to run spontaneously at idle.  Only runs at one speed (loud, not hair dryer).

Same behavior under WUBI 8.10.

So, progress.

S10FanControl now works as advertised (dresslerc for Prez!)  I have it set to 75/80/85, and with CPU Stability Test pushing the CPU @100% it hardly gets to 75C, and S10FC pushes it down to 70C.  Using normal applications (music on VLC, Word, Spybot & NAV scans) it never gets close to triggering the fan.  A few bugs:  Manual mode triggers all 4 speeds (3+off), but if you set it to speed 3 it won't go back down to any other setting or mode, you have to shut S10FC down and restart.  It starts off minimized to the tray fine, but won't go back once maximized.  The battery indicator is replaced by the AC power icon; the unit thinks it's plugged in.  Temp occasionally bounces down to 43C.  And after fooling around with the Manual mode, I left the slider at setting 1 and switched to Smart mode; after rebooting (I have S10FC in my startup folder) the fan would come on while idling (at speed 1).  Moving the slider to Off and switching back to Smart mode stopped this.

FWIW, Splashtop (haven't upgraded yet), WinXP and WUBI all run great.  Beautiful little unit, kill those last couple S10FC bugs and we have a winner.  Anyone who wants to sell theirs on eBay call me first!
