820-2914 Fan on high Speed & slow.

[Don Anton]

Hi,

This is not a liquid dmg board. How ever ASD test failed on (TG)D)- GPU Die, (TG)P)- GPU 0 Proximity, Fin Stack , Right Fin stack, Palm Proximity as bellow photo.
U 5550, 1, 7,8,9,10 has 3.3V. I replaced the SMC still same boot to the OS but very slow and fan on high speed.

Any help greatly appreciate.

I did
I just connect only key b and track pad still same

 

[Don Anton]

YOu recon FIn stack left and right proximity failed due to GPU Die and GPU 0 proximity failing or any other reason?

Any device connected on the same SMBus can generate the same problem.

SOLVED. As GPU Proximity/GPU Die/Left Heat Pipe/Right Fin Stack controlled by U5550, I replaced U5550 . Bingo. ...Thank you very much for your support. Until I trouble you again take care.
