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

2009-05-06, 21:14 PM

All,

 

Bios version 67 is now on the web for download and carries forward many updates including fan operation, resolving the backlight issue, etc.  This file is for the S9/S10 models.

 

I would expect a parallel version to be released shortly for the S9e/S10e models.

 

As a comment, this discussion has become very long and has evolved to include discussion of 3rd party developed software applications to manage fan behavior by some members, and the subsequent feature / bugs / revisions fo those applications.

 

I propose to unsticky this conversation and allow it to sunset, and start / update a netbook FAQ to include summary of the fan concerns with link to the discussion and a new discussion dedicated to fancontrol applications, heat sink modification / experimentation etc.   My thought is that these conversations are valuable, and while related to the original issue, are not the original issue.   

 

Best regards,

 

Mark

That reply from Mark looks distinctly like Lenovo have washed their hands with the problem as he is suggesting we continue to discuss 3rd party software, hardware and other modifications and find the solution ourselves.

Hm, yes...this is happens to me too. I did use account with

administrative privileges.

 

After a couple minutes of googling I found the same problem

happened to some Dell's owner too. They managed to flash

the BIOS by removing the battery while flashing (isn't that

unsafe?). The warning message on the main window of the

flash utility about using only external power is serious actually!

 

I did try flashing the BIOS without battery, either by removing the

battery while the computer is running and remove it before turn

the computer on. But still no luck.

 

My current  BIOS version is: 14CN38WW

Smo,

 

Respectfully, I don't see it that way.   This issue has been about customer reaction to one aspect of the systems performance - the behavior of the fan.  In fairness, this is not the same level of issue as if the machines would not start, crashed all the time, locked up, lost data, failed to connect to networks, or otherwise failed to do what computers do.  Still, it was a topic that many were very vocal about and we have listened and taken steps to improve / resolve the matter with updated BIOS releases leading up to version 67 just released.

 

The majority of members here have generally agreed that these updates have improved the situation.  As opinions about how this should work, how it might have been designed, etc do vary, it is difficult in these situations to produce a fix that pleases every member in every way, and allows the discussion to come to a smooth ending whereby it is marked solved, we all pop the Champaign cork and move on.

 

Personally, I like solutions that are very quantifiable and concrete.   This doesn't seem to be one of those.

 

There are a lot of different opinions about temperature thresholds and fan turn on and off points.   It is going to be impossible to create a version with fan behavior that satisfies everyone, and so the Lenovo updates are focused on improving the operation of the system, keeping it operating in an envelope that provides for it's longevity, and satisfies as many customers as possible.

 

Obviously 3rd party applications have been introduced to allow individual customization of the fan behavior by some talented members of the community.   There can be bugs and side effects to these as discussed.   What I'm suggesting is that those that want to continue to tweak settings move to that discussion and continue it as a Modders discussion.

 

I do expect our engineers to continue to incorporate updates and improvements into future BIOS releases as a normal order of business.

 

Best regards,

 

Mark

Hi.

 

Im having the fan "noise" problem too, it attracts alot of attention for me during lectures. I tried updating to the latest bios and it does not work at all. 

 

Secondly, does warrenty covers damage cause by 3rd party applications such as the one you mention ?

 

It seems like I am not the only one having this fan problem...

 

Thanks.

First, I think Mark did a good job on this. Appreciate his open minded attitude. He could say avoiding 3rd party solution otherwise might damage your machine which Lenovo didn't take responsibililty, but he didn't. (I was kind of a product mgr before, and so I know the difficulty. It is really a balance of risk and benefit.)

 

But still, there is some thermal design issue in S9/10, which is an obvious mistake in design phase. Anyway, if we can cope with it with workarounds, say, 90% of environmental situations with bios default, and 10% of situations maybe with 3rd party software solution, I'm ok with that, and still think it is a very good product.....(except that not enough 3rd party stuff compared to eeepc, or msi's overclock capability.....)

 

 

Actually, if I use it in a plane or open area, noisy? who cares?

Something else to consider regarding the fan is battery drain. When I am running my S10 on battery with the screen dimmed and the fan starts it adds another 15% load. Thats 15% less runtime simply because of the fan. I just got some copper to make my heatsink, my fan will be going away permanently very soon.

The fan issue has improved as the bios revisions get higher,  I'm sure everyone won't be happy but I'm okay with it.  I love my little s10e, it's fast...and gives me great battery life after moving to a 6 cell (4:30 hours).  Im not dissapointed in it, especially after working on an Asus EeePC 900A with a SSD (now that is SLOW) :)

I have completed my non scientific test of the following Netbooks.

 

Asus Eee PC 1000 HE

MSI U100

Lenovo S10

Old Lenovo ThinkPad T40 not a Netbook

Lenovo S10e

 

All I cared about was does the fan make a racket while I used the PC.

No test as to BIOS or CPU temp was made.

 

Surfing the Net and downloading the same .jpg files in all the PC,s (except for the S10e) a very weak fan noise could be heard.

It was so low though normal room noise would mask the fan noise. The S10e fan had a strong buzzing noise as well as a constant change in speed. I than swapped the fan from the S10 into the S10e and the mechanical noise of the fan was gone but the speed changes still occured. The S10e was very usable with the S10 fan in it.

 

So what does this mean? It appears the some S10e,s may have a problem with the fan itself and possibly the fan control system itself.

 

I make no judgements except for the findings I saw. Finally the Lenovo S10 vastly out paced all the other Netbooks I have and its construction is first class.
