Graphic upgrade, temperature sensors, fan speed problem

👍  WOW, just WOW.

I think that you're the first user I've ever seen successfully upgrading to a M4000M on these machines. Keep up the good work! This whole "not being able to control fan speed" is puzzling to me as well....

Thanks for the compliments 🙂
I think i was just lucky becouse in GPU-Z app there is a button to extract the bios. You get the warning that your screen will flash becouse turning off GPU to extract the vBios. In my case screen go black and never turn on back. I know this problems with windows 10, when PC goes in sleep mode, sceen doesn't turn on. But i manage that with no sleep option 🙂

Allso i read about the best way to extract vBios is tu disable graphic in ''device manager'' and than extract. Even this didn't work for me becouse i don't have basic GPU installed or there is some problem with the laptop.

Allso when i run flashing vBios with ''nvflash'' screen goes black and didn't tur back on. That was scariest moment when i need to ''force restart'' the PC. I hoped it wont get any problem. And it didn't but it had same vBios as before.

So the solution was easy. I run ''safe mode with command prompt'' option and from there i run ''nvflash'' so i can flas vBios without screen going black. And i was still hoping that would work becouse i didn't had backup ofcorse 🙂

First i got just bleck screen after restart. But i remember one on youtube sad you must restart couple times and than it worked. 

But yes like you sad the fan is still puzzling 🙂

Now i am thinking that there is myby the problem with nVidia compatibilities. I will try to find any informations from nVidia support if there is anyone to know any solution.

Allso i will try to figure out how ATI vBios works. Maybe there is some difference that cause the ATI card run fan perfectly but nVidia not. So i will compare this two maybe i find something interesting.

BUT MOST OF ALL thanks to you 2 guys that talk to me and give me sugesstions or solutions, if there wasnt you bouth i wouldn't get this results so fast. But i still want to come down to all 100% succesful becouse it's really GREAT EXPERIANCE i got from this and i got wider thinking about how sistem works.

And i am glad that i didn't find information that this is not just ''plug and play'' 🙂 

Before this i thought there is just a PC Bios.. I didn't know there is allso vBios 🙂 And it's logical that this 2 must comunicate 100% for the sistem works as it should and stable as it must be. 

This SolidWorks CNC machining, designing, programing... This all i want, to change this Notebook into my work machine 🙂

I will get back to give you feedback about all... Anyway maybe one day someone will try same thing and find something useful in this debate 🙂
