processor replace part Intel Core i7 2670QM 2.2 GHz Quad-Core Mobile CPU (FF8062701065500)

i'm not sure if is a problem with the model or the turbo boost technology because i have the 30 minute shutdown problem (i posted all the laptops that have the same bios but i actually have a c850)

thank you

Hi friend,
It's an HW ntel Protection lock not Bypassable (actualy implementd in ME Firmware) !
Intel ATT :

I have studied already this issue and talk about It with CodeRush and It is implemented on a MoBo's Chip so
game over !

Can the Celeron B820 be upgraded at all, or is it locked to that chip?

What the best CPU the bios will allow? I have a C850-14D with the same bios.

Cheers.

WOW! What a strong coincidence I've just spent hours trying to figure out how to mod this EXACT same bios myself, all the while keeping a tab of bios-mods.com/forums open in case I would fail.
In the end I conclude my efforts and look to the forum, and there someone just posted the very request I was about to make.

Anyway, let me just recount what i discovered. I wanted to modify the bios as to make the fan NOT spin constantly when plugged-in (ac power).
So, my efforts revealed the this "setting" most likely can not be unhidden in the bios. What I did was follow donovan6000's blog, using Andy's SLIC tool and Universal IFR Extractor I managed to get this: C850-1G3-IFR.txt

Looking through that file is what made me com to the conclusion above. But perhaps I'm wrong, or perhaps there's another way (DSDT table?) Regardless, I've given up. This just is not something that I'm accustomed to doing.

Also, my model is C850-1G3, so not the same, but the bios seems to be the same (same file-name).

PS: I did find in the txt mention of some settings regarding cpu-fan threshold's (according to temperature).

Hi friend,
I just have done this Bios Mod :

088B : 74 D8 to 74 00 jz short loc_180000865 to $+2
0891 : 74 D2 to 74 00 jz short loc_180000865 to $+2

But It seems there are no chances to rewrite into Eeprom Chip the Bios Mod !

P.S. If FPT will work We can try otherwise You need an SPI Programmer !

Here's the result: https://www.sendspace.com/file/4jm5ux

The other program could not identify the bios.

Thx

Edit: BTW, the bios link the op posted is the same as is provided for my model's download page, so they're the same.
