the cpu fan of my cf52CD....mk1 running always. is this normal ?
the cf 52 have no temp problem, the fan is running in the first 2-3 minutes after cold start. (cpu and all other temperature is lower than 28 C/82F, the fan is on)

thx.....for your help.

problem in deutsch, first the translator:
Google Übersetzer

bei meinem cf52 CD..mk1 läuft der cpu lüfter immer, auch sofort nach dem klatstart des notebooks. alle temperaturen ( cpu, hdd...sind kleiner 28 C grad, trotzdem läuft der lüfter hörbar)
der fan läuft auch schon bei klaten notebook und nur im bios menue alleine, ohne das der rechner überhaupt warm ist.
mit druckluft hab ich von außen schon alles ausgeblsen. er ist sauber.
der fan läuft nach ein paar minuten im windows im idle betrieb selbstständig an und läuft immer weiter, obwohl das notebook im idle betrieb ist.

ist das normal ?
ist das bei euren mk1 auch so ?
habe 2 weitere cf 52 mkII, dort läuft nie ein fan ( nicht hörbar, nicht fühlbar).

bitte um eure hilfe

danke in voraus, thx

 

Thank you for posting translated English and original German.
Very good.

I have a cf 52G. The fan turns on and off as needed. I have been using it today for several hours and the fan is currently off.
Please post full model number..It will help us to diagnose the problem.
CF-52CDxxxxxxx

 

1000 thx for your reply ))

the complete model nr is CF 52 CDKBVAG.

in german:
Google Übersetzer

die komplette nR ist cf 52 cdkbvag.

bitte versuchen sie mir zu helfen, ich finde in germany keine möglichkeit mehr.
meine fan läuft immer. im leerlauf der cpu (idl) läuft er auch immer, deutlich hörbar und der luftstrom ist auch deutlich fühlbar.
ich weiß nicht ob er noch schneller regeln würde. er läuft aber immer schon im kalten zustand. notebook ist zu kalt dafür das fan laufen soll.

das problem hängt nicht mit dem betriebssystem zusammen, bei einem test ohne HDD und DVD device läuft der fan auch sofort im BIOS mode.

bitte um info und hilfe

thx

 

Check ur running tasks (all users), msconfig, services, virus scanners. Also ur energy settings.

Im BIOS Modus ist das hochdrehen des Luefters normal. Boot doch von einem anderen Betriebssystem (Linux-Live-CD, -USB-Stick).
Schau doch bitte nach, welche Prozesse gerade aktiv sind. Im Taskmanager bei Prozesse unten auf alle Benutzer klicken. Dann nach CPU-Last sortieren und schauen, welche Prozesse die meiste Last verursachen. Vielleicht ist damit schon der Waermeverursacher zu finden. In der MSconfig auch mal nachsehen, was da alles automatisch startet.
Ist das ein Model mit ATI-Grafikprozessor? (hab noch nicht nachgeschaut in Deiner Modelnummer). Vllt liegt der Fehler auch dort....
Ist bei Energieeinstellungen des Betriebssystems ausbalanciert eingestellt? Auch das korrekte Kuehlungsmodell ausgewaehlt? Versuch doch mal die Panasonic energy mobility option.

 

What is the bios version? I seem to remember a similar problem that was related to the bios somehow. A bios flash solved the issue..

 

I am not positive, but it appears that your cf 52 is an ex telecom machine. It may have a custom bios...
I will search for the previous post.

 

thank you for help.....

alle prozesse ok, cpu last auf minimum.
danke für den tipp

bitte schau einmal ob du etwas über die maschine findest. vielleicht ist das problem echt das bios.
wäre sehr dankbar für hilfe um das problem zu lösen.
ich weiß nicht wie man das BIOS prüft ob es falsch ist oder einen fehler hat. ich habe zu wenige informationen im internet gefunden.

danke euch für die hilfe

 

Google Übersetzer

kann der software stand vom : Embedded Controller das problem sein ?
der controller steuert doch den cpu fan ?
sind die beiden software von BIOS und Embedded Controller ok, oder das problem ?


das habe ich gefunden, ist aber nicht mein problem mit dem cpu fan....
http://forum.notebookreview.com/pan...ghbook-phoenix-bios-update-help-needed-5.html

thank you so much.....

 

Translated text

can the software release from: Embedded Controller the problem be?
the controller controls but the cpu fan?
are the two software BIOS and Embedded Controller OK, or the problem?


I have found but it is not my problem with the cpu fan ...


Here is a search to look at....I can not find the post I was looking for.

sorry, i translate the text bevor....

Please check the software they stood by the BIOS and the rest of what I wrote.perhaps it is the BIOS and an update is needed?please check the written data ' thank you.....n8

 

I think a bios update may solve the problem..You will need to wait for someone who has a newer bios to send a copy to you. I don't have one for a cf52C

 

Do you have a Linux Live CD to try? I use them for diagnostics and to verify that my problems are not software related.

My choice for this would be Linux Mint 13 or 15. Ubuntu is good too. 12.04 LTS. (Long term support)

Google translate says:
Haben Sie eine Linux-Live-CD zu versuchen? Ich benutze sie für die Diagnostik und um sicherzustellen, dass meine Probleme nicht Software verbunden.

Translated from above response. It seems to do it without any drive connected also..

R is the complete 52 cdkbvag cf.

please try to help me, I find no more possibility in germany.
my fan is always running. in the cpu idle (idl), he also runs always, clearly audible and the air flow is also clearly perceptible.
I do not know if he would settle faster. but he always runs in the cold state. laptop is too cold for it to run the fan.

the problem is not related to the operating system in a test without HDD and DVD device also runs the fan immediately in BIOS mode.

ask for help and info

 

good morning guys ....

@ jeffI know myself and not nit linux ubuntu from which is to simply let the system simpler times run from a usb stick?maybe it would be enough if linux is finished and I started watching the fan?thanks for your idea.

@ shawnwhere can I get the BIOS, I do not know?I find this on the net not much, only in your forum, because once the WWAN Gobi was retrofitted and made ​​a BIOS update.I've just been back since the other (second) HDD (Samsung HM160HI) fitted with new win7 in the CF52.Since the fan is running IMMEDIATELY when finished booting win7 readable hat.alle temperatures below 33 degrees Celius (91F)with xp sp3 it does not start until after a few minutes.if a mechanical defect or would exist on mainboard, it would be no different with other operating system??

what do you think .... thx 1000, michel

 

Someone on this forum will have a bios. You will have to wait until they read your post. Not as many people are on the forum on Sat or Sun..

Yes Jeff is talking about booting to Linux or Ubuntu. A USB stick or CD will work to test your system.

 

invite me down ubuntu 11:10.values ​​then try to boot with cd. I hope ubuntu has the driver for the CF52?.thank you first, great forum ))))greez from germany

 

I now have to test it on the ubuntu 11:10 CF52I started it off CD. the problem with the fan is the same, he also runs here.I can read with ubuntu now what helps me with the problem by the fan?

@ jeff
but you had an idea?please tell me something I can now do with ubuntu to check the fan.

thank you

 

If the result is identical with Linux then:

1. Shawn is right. Wait for bios upgrade or
2. You may have mechanical problem.

Drivers are included with Linux. No additional drivers are necessary. Each time Linux loads, it writes kernel including drivers for the equipment that it sees (detects). If equipment is NOT DETECTED then it means mechanical problem or bios issue.

From terminal try this:

Code:

dmesg | grep cooling

my CF-52 say acpi device:01: registered as cooling device

Above for your information.

Code:

sudo apt-get install acpi

then

Code:

man acpi

#manual for acpi

Code:

acpi -V

#shows all acpi devices

Many items to look at.

Good luck.

Jeff

 

hi jeff
Thanks for your instructions.the first command I could not type "dmesg | grep cooling"from the second command is nothing more left. He then reports the error that ACPI is available. from there I can not run no more with your input.is probably so because it runs from the CD without installation!.
what a silly problem-just because the fan always running.

could you make me a Screeshot of the input?

thank you, michel

 

You are correct.

Another one that lists (ls) all hardware (hw) is:

Code:

sudo lshw

You can get some information with

Code:

dmesg | grep acpi

 

I am with CF52-Axxxxxxxx and I have the same issue since I bought it (second hand). The fan is always on, regardless if the system is idle or on load. It's 100% NOT OS related because I did a clean reinstall between both XP, Windows 7 and once a FreeBSD. Fan starts since I start the system and it never slows or offs until I shut down.

 

sorry had to solve other problems the last time CIH'll read sometime soon and see if I can find something.It is interesting that your cf 52 makes with number starting with 52 CF A. .... the same.how long does your battery in normal operation (internet)?going the next day bad time to have to take care of the problem. WE will only be somewhat time again.maybe you think of something, I would be very happy.p .. s how are your temperatures if your fan is always running (cpu, graphic ....)?to the daily, michl

 

Of interest would be the bios and ec numbers shown on both these machines.

Curious.

 

Info from previous posts

wattie
My BIOS is V1.04L21, the model is CF-52 mk1 (serial starts with "A")
The exact stock model is CF-52AJCBDBM

 

Thanks Shawn, you've done it again.

 

Oops I've done it again! Oh that's Britknee....

 

I have a CF-52CCABVBM with BIOS: V1.54L25 and EC: V1.50L12. I can copy the BIOS and send it to you if you think it will work. The fan seems to run normally. I will check tomorrow. I just did a restore and am doing MS Updates atm.

Shawn, don't you mean ' Oh, that's Britknee. Oops, I've done her again!'?
If you want, I can send you my "I Fxxxed Brittney' button, for real. :thumbsup:

 

Mine is "CF-52AJCBDBM"

The battery is original 7.8Ah (as far as I remember) - lasts around 4 hours (as I said - the fan is always on). Could be less if the usage is stronger. I usually use it for Internet only.

P.S. Ups, Shawn was even better than me - he found my BIOS rev

 

do you think now that it is correct but if the fan is always running?@ Watti ....when you run the fan ever?comes with your cf 52 only cold air when the fan is always running?mine is only cold air, so no reason for continuous operation, fan runs but still good.would you send me a BIOS?thank you michl

 

The CF-52CCABVBM I was working on has had a full restore and all MS updates. The fan starts running once Windows is loaded. Temp of CPU sits about 30C at idle.
@cf52, are you saying your fan is running at top speed or running at a very low speed? If it is running at top speed, you have a problem. If it is running at a low speed and/or cycling on/off/on/off then it is operating normally and the only problem you have is sensitive hearing.
If you need more battery life, shutting the fan off will not make very much difference. Undervolting your cpu will give much better results. Buying a second battery is another way to increase your unplugged runtime.

 

I need to increase MY unplugged runtime.

 

It's not at full speed - the fan is running at low speed. But again - it's sensless to have the fan running when CPU temp is 30C when C2Duo can handle 50C with no problems...

Things like "quietness" and "less dust in the body of the laptop" are not unimportant. I wish that there was a fan control... but there's not.

 

Man, you got that right. If I figured it would help, I would send you a box of batteries.

 

I have used this with success on overactive fans... Notebook Hardware Control (NHC) - Homepage, Downloads, Help, Docu, FAQ, News - www.NotebookHardwareControl.net

 

good morning ...thank you for your great help here.my fan is always running nin. with slower speed that's right.Yesterday I started ubuntu times as version live cd and there intentionally watched video (you tube). I've noticed that when the video is fan speed faster and slower in still image again, so the board regulates the fan. which is ever good, I think.I have already read all sorts of temperatures, but a GPU was not there. maybe the GPU's too warm because temperature paste is missing or bad.ye by this experience? ......thank you for your reply, michl

 

Download TechPowerUp GPU-Z - it will give you the GPU temps.

 

hy ...
I'm stuck with a problem. I will the next time the device remove and look for the thermal grease times. I have the suspicion that it might be the GPU which can derive no heat. I do not know.I'm writing here when I know more.if one still has an idea, please write here.thx micha

 

Just use afuwin to save ur BIOS. With AMIBCPv4.53 u can adjust at the point Debug/ThermalConfiguration/ActiveTripPointFanSpeed at which temperature the fan speeds up and turn to low.

Sadly I reached the limit here to upload pictures, so I can't add a pic to help u out. ( And I don't want to delete some old pics here...)

 

onirakkiss...I could start another thread on Toughbooktalk so you can post some pictures...

 

^^^ If CF52 is willing to follow us on the other site/side...

 

OK...I started a new thread here ~Toughbook Talk~ Toughbook Discussion • View topic - Help...CF52 Fan problem. .

onirakkis...you can go ahead and post the pictures now, cf52..click on the above link. If you want to post in that forum you will need to join. See you there :thumbsup:

 

thank you I have seen the new contribution, the times'll try.I divide the 52 cf soon again to see if it has a fault.

thank micha
