A solution for Lenovo 3000 Fan noise

2008-05-26, 20:45 PM
I search internet for the annoying fan noise
for my lenovo 3000 n200.
There is a way to control the fan. I think it also works for n100 series. My machine works very quite now. In fact I will never buy IBM after this again. Because of the pain it gave me before. HERE is the solution:

These steps are risky for your laptop. Use it with your own risk. It is worked my particular case. But have no guarantee on others.

There are two problems. 1 with voltages, 2nd with fan control. Here is the method worked for me :

Step 1- Somebody figured out that there is a voltage setting problem (shame on IBM). And I think it is true. Since my machine corrected voltage after following his method. The machine thinks it has a desktop cpu. I cant find his post now but here is his method: Install rigtmark CPU clock utility. Open "advanced cpu settings". Check "Mobile" on the cpu type selection. Select apply these settings at startup. Then in profiles "configure performance on demand" and enable this profile. So now your CPU has corrected voltages. You can check it with CPU-z.

Step 2. Install "Notebook Hardware control". This german guy wrote a script to control fan for "Notebook Hardware control". http://www.thinkpad-forum.de/thread.php?threadid=33888&threadview=0&hilight=&hilightuser=0&sid=22006dc051c62b2d1eefa0032deab09c&page=3

Download his file in his posting : LenovoN200_ACPI_0.21.zip
. Correct the file lenovo.cs . There is a bug in the file correct these 2 lines :


instead of
if ((max_temp > 70 && max_temp 80) || _TZ.fan_on_modus == 3)

User this line :
if ((_TZ._tz > 70 && _TZ._tz 80) || _TZ.fan_on_modus == 3)

And instead of this
if (max_temp >= 80)
Use this
if (_TZ._tz >= 80)

Now edit lenovo xml. and change name=" " part with you machines orginal part. Donot change "class name" even if it is not your model.

Copy these files to the acpi directory under NHC. Restart NHC. On the ACPI tab of NHC enable ACPI. if it didnot give error then youre done. push "Show ACPI control system details" and set your desired settings. I set 58C for fan off and 65C for fan on.

best.

PS(if the solution work credits belong to the guys that wrote in the posting on internet. I just gathered them together.)

A few typo an notes on my previous posting : STEP-1. even if rightmark sees as mobile on the cpu part. set it to desktop and set back it mobile and then push apply. Now configure "performance on demand" profile. (an easy way is Check all stuffs in this profile). Then enable it from tray icon. Now you can verify by cpu-z that cpu voltages are changed. I am really shocked by this problem of IBM. STEP-2 Download the file that I mentioned. There is another file with similar name on the posting. There is a typo in my correction : It should be instead of if ((max_temp > 70 && max_temp 80) || _TZ.fan_on_modus == 3) User this line : if ((_TZ._tz > 70 && _TZ._tz 80) || _TZ.fan_on_modus == 3) And instead of this if (max_temp >= 80) Use this if (_TZ._tz >= 80) Hope it works for this annoying fan noise...

k-man, welcome to the forum,
 
unknown to ilker and after ilker posted the link the german forum moved to a different software version and this has caused his link to be invalid.
 
@ilker,
 
maybe you could re-search the german forum and edit your post, (click on options top right, then choose edit), if you should experience difficulties let me know.

Andy
