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

2009-04-15, 19:06 PM

@carsten, dresslerc

 

i was playing around with NHC a little and maybe register 153 (0x99) is interesting. it gave me values between 3 and 5, seemingly in concurrence with three different fan speeds.

 

here's the code if you want to try. see debug mode in NHC

 

public static class LENOVO { #region Notebook Lenovo S10e : class S10e // // class author: Peter Pan // public static class S10e { public static class FAN { public const string description = "Notebook FAN Control – Test Program"; public const bool default_enable = false; public const int icon = 2; public const int refresh_interval = 5; // 5 seconds public static bool refresh() { int value = 0; ACPI.FIELD.ReadByOffset("_SB.PCI0.LPCB.EC0.ERAM", ref value, 153, 8); return true; } } } // #endregion }

 

 am not fit enough in coding to figure out if this can be directly written. maybe it's totally bogus, i dont know.

@pete_p:

Good idea, but there are two aspects against it. The value changes between 3 and 5, right, but 1. there is no value 0 or another when the fan is off (the total number of fan levels is 4 - off, medium, fast, very fast - so we need a field with 4 different values) and 2. the change in value of 0x99 and the change in fan level do not refer to each other when you look at the time axis (sometimes shows 3 when fan off, sometimes still 4). 

 

And when I have a look at the S10e's DSDT...:

TEMP,   16,
              Offset (0x99),
CRTH,   8,
CRTL,    8,
              Offset (0xA0),
SW2S,   1, 

 

I was just trying to make a debug tool for the ACPI tables to get an overview which fields are changing their values regularly. The debug mode in NHC is okay but you cannot export the data to a log file or something else and it really is no fun on the small display. But I don't get this §$%&?! winio.dll running...

 

But a very good idea, thank you. Sorry, I have no idea what it is.

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

I remember Mark_Lenovo mentioning here somewhere that there are 8 fanlevels. where the lowest isn't even audible

for me it showed

3 seemingly off

4 low speed

5 higher speed

in sync with timeaxis. will try out a bit more.

 

didnt get to the hair-dryer speed. any idea how to get it really hot? i had two 720p videos running but it didn't get off...

 

keep in mind that it updates only all 5 sec.

Ok, please keep us up-to-date. You can put some tape over the ventilation opening so the warm air cannot escape.

 

I had the interval at 1 second. But if it has something to do with it I think 5 would even be the highest level we know, at least it is the highest level I know from my S10e and it is 3 when the fan is completely off (not barely auditible, it is off). So value 4 must stand for two levels... so for my opinion.....

 

As Mark_Lenovo stated that there are more levels I think he was talking about the new fan control in the 58/59 for S10, as KalvinKlein also mentioned that there are new fan levels that we don't know from the S10e. I am still sure that the S10e 57 had only minor changes that do not fit to the results the S10 users reported.

New, specific thread, for fan control program?

2009-04-15, 22:57 PM

@dresslerc:

 

Just a thought, but maybe it would be a good idea to make a new thread for your fan control program - with links to downloads and all? That way this thread could continue as it was with the BIOS problems, and the new thread would serve a greater purpose not drowning in all sorts of other problems. Also, if the title is good, it would be easy to find the program, and the discussion, by the help of mr. Google. :)

 

Keep up the good work! Your program has really made this S10e a perfect buy, and I will donate as soon as I get my new VISA.

Thumbs up - Think this would be the best. Maybe a new thread for the "how to transport the heat better"-issue (heatsink modifications aso) as well? Otherwise, this thread will be used for these two things only and no one of Lenovo might remember that they wanted to provide an official solution...

Re: Battery Meter

2009-04-16, 15:18 PM

The strangest thing happened this morning:  I have my laptop set to go into standby mode when I close the lid.  I had the laptop in standby mode and switched from my 6-cell battery to my 3-cell battery to go out.  When I booted the laptop up again, instead of resuming from standby, I got the "Windows Error Recovery/Checking Disk Blue Screen. 

 

However, when the system had recovered, oddly enough the battery meter is now working.  With a functioning battery meter I can now say that running Windows XP Home (SP3) / BIOS Update 58 / and S10 Fan Control 1.0.0.0 my S10 is pretty much perfect.

 

I have the Smart Mode options thresholds set to: 75/85/90  I don't know if that's too high or not, but my system stays pretty cool and quiet, but the fan does kick in on low-medium when I'm running a lot of apps or doing relatively CPU intensive processes.

 

Thanks Dresslerc/Carsten!  I'll be breaking out that credit card on PayPal this weekend.  Your work has been well worth it!

p.s. I think the idea of a separate mods thread is a good one......Perhaps the Lenovo engineers can check it periodically for tips/ideas :)

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

Hi,

 

I've been following the progress of this and several other threads regarding this issue, mostly silently. It seems that my S10e has got louder since upgrading to the 57 bios although it revs up and down less... 


Two questions - Has anyone else noticed this? Does anyone know if there is a guide to remove the fan mesh?

 

I have opened my S10e to have a poke about but didn't want to dive into removing the fan assembly without some insight as to what to expect!

 

I find the whole thing annoying as some of my work mates have various Asus, Samsung and Dell netbooks and none report fan noise/overheating problems :smileymad:

@mrpubman:

 

I have the S10e, and my netbook was "fan crazy" out of the box. I updatet to BIOS 57, but still the same - so I went for the 58 BIOS for the S10 (not e). This BIOS (58) made the fan spin less often - but was still an annoyance, so I was "überhappy" when the fan control program became available. Now the fan only spins for a few seconds every once a day (at most) - so it's almost as silent as a deadly fart. The program is making the S10e a perfect buy, and I recommend it strongly (but you will have to upgrade your BIOS to the 58 (or 59) for the S10.
