Hello! Need urgent help P.S !
Fixed initially a short on memory bus +1.8V rail by removing on board cells getting hot one by one, till last cell.
Inserted a DDR2 in SODIMM slot1.
Switched lap, all main voltages are ok, but fan and display are failing.

Voltages measured on FAN & Thermal Sensor IC "EMC4000" are attached.
Issues found :
Pin6- FAN_OUT : 0V ?? no spinning.
Pin30- THERMTRIP_SIO : 0V low, I guess, it should be high i.e +3.3V p.s correct.
Pin29- HW_LOCK# : 0V. Is it Hardware lock signal ? Should it be high level i.e +3.3V ? p.s correct.
Any idea on next steps to help solving issues would be much appreciated!
Thank you
