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 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! 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 |

Because you are engaged in deep research 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 |
