Hello

I have a strange issue with this laptop:

Procesador: Intel Core i5 3210M (2500 MHz - 3100 MHz)
RAM: 8GB DDR3 (1600 MHz)
Video Cards: Intel HD Graphics 4000 (Integrada) NVIDIA GeForce GT 650M (DDR3) (1GB)
BIOS version : P04RAB
MICOM Version: P04RAB

It stopped working for no reason, it turned on, I could hear the cpu fan but It got no image , so i took it to a tech store and the guy manage to "fix it". It now turns on but it shuts down after 45 minutes with no warning and not by overheating (I have checked the cpu temp), the tech guy has no idea why. I checked the charger with a multimeter and the voltage output is correct.

Someone in other forum sugested that BIOS ME region issue, needs to be cleaned. I Analyzed the BIOS using ME Analyzer and it is the result I get:




Any help would be apreciated.

Acodrding to the guide provided by @plutomaniac, I need an image dump of a model which comes with ME firmware version, the problem is that I cant find it anywhere. Samsung does not provide this files individually, the only thing we get is BIOSUpdate.exe that updates the bios automatically.

@plutomaniac, I have a question about the the "pinmod" to bypass the error 26 :

this is my chip :

and the pin numbers I found about it is this:

Are these the right pin numbes?
I just want to confirm before doing it, I assume that if I do it wrong I could short out the motherboard

You need to short pins 1 (DVDD) and 5 (SDATA-OUT) at that audio chip.

I just finished doing the steps on the cleanup guide but now im getting error 28 : Protected range registered are currently set by bios, preventing flash access please contact target system bios vendor for an option to disable protected range registers
Any advice ?
Thnx

EDIT : Nvm , it worked, no shutdows after 30 min!!!
Thank you !
