Could anybody inform other readers what is the basic reason of such bahaviour? I have same problem with same PG, unfortunately it looks like Siemens mistery to living it not commented. |

First you should check if the BIOS is the newest version. Watch it, the different PG's got different BIOS! |

Unfortunately I cannot found such utility. Do you have a link for this tool ? |

1. Follow Smurf' s suggestion. 2. In case of PGs I wouldn't take a risk.
In Google have more info. |

Hello zeemens I no have field pg p4, so I suggested the BIOS settings, based on the settings of other computers, although it is possible to complete the PG and there is such a tool. By configuring the chipset and the CPU is useful to look at the intel site can search the site intel. In general, the fan better change, or at least smear. Perhaps there is a problem with the sensor speed. What about soft cooler: it lowers the CPU frequency when it is reduced load. So as the method is quite suitable. Especially for the PG, where speed reduction is tolerated. And you do not have any more tools for managing fan type speedfan or other? may be a conflict of utilities? |

It seems we are 4 person club now... Club of PG-M fan problem: https://www.automation.siemens.com/tf/WW/en/Posts/39795#top So it is rather common, right? Anybody want to join us? |

Welcome again all readers! Today, following gre_m suggestion I digged out some useful information, that can be read HERE in original, but anybody not familiar with russian better use Google translator HERE. In general one guy has burned out serial port in his FPGM and he discovered that GPIO chip LPC47N252 made by SMSC is used to control serial port and fan speed. After lecture of GPIO manual that can be found HERE some new possibilities to resolve can be seen on the horizon, but I need somebody who knows more than I how to flash it and where could be theirs settings available ex. via driver. It may be that all is just speed feedback read-out as gre_m said. Looking forward to hear from you. Alltogether "we can", as Obama used to say (offtopic joke). |
Last edited by: zeemens at: 6/8/2011 10:02 AMSpeedFan can see 3 of PWM outputs, PWM0 is really controlling fan (11 levels), PWM1 does no change, PWM2 controls brightness (8 levels). Real speed values cannot be seen. PWM0 can be controlled shortly, but every 8..12 seconds (i.e.) when you see any change on PG panel) original control overrides manual setting. Meaning SpeedFan is useless in our investigation. Last edited by: zeemens at: 6/7/2011 5:16 PMAbout sofware cooler, I found in SpeedFan description of this chip: It has been confirmed that SF can change fan speeds with this chip, but I still couldn''''t figure out how to access those tachometer inputs needed to report fan RPMs...

Here you can find some tools to heat - up your CPU: http://www.pc-freeware.com/intelburntest-23 I would like to know surely that fan is working before travelling to a comissioning job to china i.e. ... |

No, I didn't use any other software for triggering fan. It was happened with load of around 65% when antyvirus scanner and defragmenter was running at the second plane. No other software. I also agree to have such a "overload protection" switch embedded, but Siemens should clarify what level is set and what should be user's reaction. Another track to be investigated: Have anybody used Simatic PC BIOS-Manager, maybe there are some switches or limits that can be changed? I am not sure whether it is worth 43,75€ (50 points)... Anybody tried it? cheers, Zee |

I never heard about a Simatic BIOS Manager. Your link shows a BIOS, not the Manager.... |

Did you have done a look at the manual, if your problem can be solved? But i dont think that this tool makes sense for a very PG. |

Completely agree. High-cost notebook. And that's why users should got something more than the others and specialized for its tool... Here even for creating partition or disk image have to pay (Simatic PC Image/Partition Creator), while there is a lot of much better utilities free of charge. Completely weird policy IMO (offtopic). Ok then. I think it is only reverse engineering of EC settings left to do. In case of spare time (maybe some day :D ) I will start it. Of course will inform you all what I digged out. So far will install external quiet fan to not let EC lock down. It is the most effective solution regarding price/performance ratio. cheers, Zee |

Hi, zeemens field pg contains at least two sensors: temperature of the motherboard (chassis) - typically thermistor, and temperature of the CPU processor - thermal diode integrated with the chip. Termorezistormozhet degrade due to misalignment of the measuring bridge, the actual sensor and give the wrong temperature. Degradation of the diode unrealistic, I guess. Therefore it is necessary to evaluate / look thermistor placement on the motherboard. What's the thermal contact. And forgot to say earlier, you have to blow the radiator or other heat pipes. That blow, use a vacuum cleaner suction on the ineffective |

Dear all, Enclosed my procedure for 1) clean-up PG inside 2)exchanging thermal compound and 3) greasing fan bearing for Field PG M. Good luck to all beginners! I hope I made many of you decided to made this improvement. Don't worry, it is nothing difficult. Believe me, it was just 1 hour to perform, and 7 hours to write this procedure. In case of any questions, opinions and critics feel free to contact me. I will edit/update with your help till perfect final. cheers, Zee Part 1 of 2 AttachmentProcedure1.pdf (806 Downloads) |

Hi, zeemens Smallcomment on application of thermal paste: I read that grease should not be applied thick, so as not to cause a poor contact with the radiator crystal.The thickness of the layer should be the minimum necessary to fill surface defects. and not be a piece of butter in a sandwich processor-coolsink . On your photos it seems to me that this layer is excessively thick. I believe - you will understand my bad englsh. Do it for yourself and get satisfaction from the fact you did it - it's a great thing |

Dear all, Thanks for your warm replies, really appreciate that! A photo of CPU covered with thermal compound (TC) is sligthly falsing real situation. In fact there is amount of, let say 2 rise grains spreded across cover and beyond. This particular TC Amasan/Armack T12 is silicone based, containing ZnO (zinc oxyde) and it has very liquid state at least comparing to another TCs. It's German MSDN is here (sorry, did't found English one). Regarding to this article I am very sceptical to spreading TC with finger! This approach is made on wrong (in this particular case) assumptions that 1) both areas is perfectly flat 2) they are perfecly parallel to each other(!) and 3) there are no vibrations at all. First you open your PG to see that it is almost impossible with micron accuracy. This is not a pharmacy. It is much better to exchange TC more often IMO. This is tough industrial notebook rather than home appliance amplifier. You must to remember that there is quite strong force from 4 huge springs (not common in laptops). And (this I forgot to mention) that screws must be tighten to the end. Within 12h TC will spread perfectly everywhere it need to. On RS components (wold-wide known) page you can found many of TCs. You can see how many silicone based TCs you can found. Actually metal particle TCs there are not in common use due to it rather solid state, difficult to applicate. Amasan TC can work in range -30..+200 deg.C (!). cheers, Zee |

Hello zeemens Excuse me for a long link http://www.google.ru/#hl=ru&xhr=t&q=thermal+compound+to+the+processor+how+to+apply&cp=46&pf=p&sclient=psy&newwindow=1&site=&source=hp&aq=f&aqi=&aql=&oq=thermal+compound+to+the+processor+how+to+apply&pbx=1&fp=b730e7600dccbe54&biw=1277&bih=587 This link formed by google from search string "thermal compound to the processor how to apply". Because you are engaged in deep research, perhaps it is useful. I would like to say in addition that the thermal paste may be different for heat transfer, and is devoted to reviews of the quality of thermal paste. However, in practice often have to use what's at hand. Success |

Thanks to my colleague I have tested this SW, but there is nothing to be change in BIOS. Anyway, there are some important information in hex thay may help with register mapping, i.e. where are LPC74N252 registers mapped onto BIOS. The thread is going on... cheers, Zee |
