N551JM - cold CPU , CPU vcore present-Clean ME

[magneh]

Hello,

Ive been troubleshooting a N551JM mobo that turns on fully but cpu doesnt heat up at all, only the coils get warm

Can someone clear ME region of my original dump so I can test to see if BUF_PLT_RST comes up and cpu starts to work.

Thank you

Your model number in your bios backup is G551JW . The silkscreened part number on your board will be N551JM Rev 2.0 ,G551JW should be on a sticker somewhere,and you can check the GPU part number , the G551JW has a GTX960M, the N551JM has a GTX860M.

Try this bios with your dmi + clean ME firmware.

Hi,

For sure it has a 960m , as the nvidia chip is a n16p-gx-a2

I dont have the full machine to check the silkscreened PN

I will trw those dumps in a bit and report back

Hey Flea!

Thanks once again for the file. Appreciate it

So I ve tried with this dump and when applying 19V board starts up to 360 mA, but still cold CPU.And BUF_PLT_RST still 0V Nvidia chip is still warming up

Now if I short the power button pins on the keyboard connector for several seconds, the board shutsdown, but its taking from 21 to 37mA jumping around randomly when off. Could be a sign of something wrong with the PCH or even maybe CPU?
Anyone with more ROG board experience that could suggest something here?
Or just a lost case?

Thanks for all the help guys!
