Hello and congratulations for this great forum full of knowledge!
Here is my problem: I have disabled the discrete ATI GPU by removing PJ19 jumper (+VPCIE) and PL8 coil (+VDD_CORE) and swapping RI55 with RI51 and RI53 with RI56 (SKU: SG_PARK => UMA).
The computer does not detect ATI GPU anymore, but the CPU runs at 55°C and up when in idle. I then cleaned the fan and heatsink and applied another thermal paste, but nothing changed.
I have also tried to flash the BIOS+EC (F.48) again from Windows and during startup (by holding Win+B). Still the situation has not changed.
I think the problem is somewhere else.
I believe someone could lead me to the solution
Thank you all in advance!
