Re: Fan Control for the S10(e) - user-developed solution

2009-06-05, 19:17 PM

Hi Carsten,

 

I have installed S10 Fan Control 1.0. and have put it under start up folder. Everytime just few minutes after the booting, the fan starts spinning, non-stop, till the computer is turned off... 

 

About BIOS version....errr...no clue, how do I find out? :smileytongue: I only know my notebook is S9e...

Hi.

 

Either you have a look in the BIOS itself, there it is the second entry on the "Information" page

- or -

you can use CPU-Z. You see your BIOS version right here:

 

I bet it's 57 or earlier... :smileywink:

 

 

Greetings

Hi.

 

Ok, you have three options:

- BIOS update to 66 or 67

- Download S10FanControl 1.0.0.1, open the options window and set the offset to 0x51.

- Use NHC and my config tool.

physically fixing the fan with a staple :) 
 

i'm glad its finally over. really glad. its been months of pain thinking how i can get rid of the loud grinding fan, and seeking tech support in singapore in vain. also, i should have known earlier that it is a physical/ design fault that fixing via fan speed would not help too much - i cannot be sure, but please note that there may be other reasons for fan noise other than grinding against the housing, which is what i experience. 

 

A side note regarding support - in singapore, distributors take no liability for this noisy fan problem, directing customers to the sole official lenovo support for S10 netbooks - which is actually subcontracted to a firm called 'megalink systems', which really could use an overhaul -

1. no clear contact - i found more than 3 different numbers, and nobody picked up my hours of calling during working hours,

2. no note on opening hours - all i know is they were closed for 3 times i visited them..

3. the list goes on... simply google for 'megalink lenovo support' for an interesting read. However, I take my hat off for direct, official lenovo support for my other thinkpad laptops.

 

I give my thanks to Thiti - who written how he fixed his noisy fan in this blog -http://thitiv.blogspot.com/2009/04/lenovo-ideapad-s10-fan-blade.html  it gave me some ideas whats happening but the main thing i found from this blog is that there exists a hardware maintenance manual - http://www-307.ibm.com/pc/support/site.wss/MIGR-71062.html to guide those who wish to physically fix the problem from it's source.

http://thitiv.blogspot.com/2009/04/lenovo-ideapad-s10-fan-blade.html


 

My fix is simpler and cheaper version of other physical fixes -  i simply made more space for the fan to move without obstruction, and didnt apply any special gel for the heatsink.. dont see why i should spend so much fixing a S$600 toy.

 

Follow the steps below at your own risk!

 

Firstly dismantle the S10 and extract the fan, page 86 of the maintenance manual could be helpful (see link above) - to reach the fan, almost every screw should be unscrewed. do be gentle, patient and observant if you're doing this, be very organized (with the screws, screw cap, etc) and operate in a bright environment. Note that when you reassemble, strictly follow the steps backwards, noting the screw size and colors =_= (i redid the whole thing because my last screw couldnt fit the last hole..)

 

After I successfully extracted the fan out, i realize that the fan has a slight tilt to fit in the S10 frame, and because of this, it grinds on one side of the bottom metal panel of the fan housing - it seems that there is only one area that does not have sufficient clearance, thus creating the noisy friction.

 

my miraculous solution is actualy some staples acting as a 'washer' to seperate the fan from the housing,

 

Now, the S10 fan is now very quiet, not noticeable during bootup/etc unless i put my head on the keyboard (this is in my own room alone with no music, traffic, etc)



heres some screenshots of what i mean/ did - 
http://img15.imageshack.us/img15/8410/s10fan1.jpg
http://img329.imageshack.us/img329/7944/s10fan2.jpg


personally, i wouldnt care much about making the fan/heatsink better with metal pieces and artic paste - dismantling the S10 is already a big risk n chore, and i really dont want to risk damaging anything else.

 

by the way, if you suspect your fan has the same problem, bios 66 or even bios 100 may not help you - i was using bios 66, and during bootup, etc the grinding noise still startles my dog.


 

do hope the above is useful! :)

Thanks, Jason for giving me the credits. I'm happy my findings are useful to you guys. My S10 has never annoyed me once ever since. I've used it as my primary "laptop" and it's been 2 months now.

Dear Carsten,

 

I don't know if I'm putting my problem here in the right place.

 

My S10e has no problem with a loud fan, but I think it's overheating since two days.

 

I've running it with Ubuntu 9.04 kernal 2.6.28-13-generic

And Ubuntu locks itself everytime after a couple of minutes.

The temperatures shwon are about 47 - 50oC, not really an issue.

Putting my S10e in our server room with AC it can run for a day without problems.

 

What could the problem be ???

Hi.

 

@ jacquesschrier:

No loud fan? Lucky guy. :smileywink:

I'm not really familiar with Linux, but in general the S10e shuts down itself when it's getting too hot.

- Which BIOS version?

- Have you changed anything two days ago?

- Depending on your location: what is the temperature outside? The manual says that the max temperature for operating the S10e is 35°C (31°C at altitude > 3000m). Even in Germany we reach > 35°C...

- Do you use any fan control? 47-50°C is very high for a BIOS controlled fan, at least I've never reached it. Some guys reported a faulty heatpipe construction in the 90+ pages thread.

- Perhaps you have to clean up your ventilation. I'm doing that regularly (approx. 1/2 year).

- Perhaps you should open a new thread for your specific problem, maybe a few more guys will read it and can give you a hint.

 

@ Lenovo:

Are there any updates from your side? There hasn't been any improvement for more than two months now.



Greetings

 

Carsten

Dear carsten,

 

thanks for replying.

 

The only thing I rembered is that I had to move the laptop and took it in a corner a bit to tight (maybe).

After that the problems started.

 

About the temperatures, I live in Uganda Africa, the temperatures are always between 26 - 38oC

This could be a problem for the laptop, but then Lenovo should not sell them here in Africa.

 I don't have any fan control, the laptop is just one month old, so I don't believe in dust.

 

At the moment i'm typing this on the S10e and the CPU temp. is 54oC

HDD temp is 49oC

 

Maybe I should open a new thread...................  :-(
