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 (830 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 |
