    I have replaced R5002 is a 100k resistor...no changes

    What do you mean by force with 100k

    R7095 is broken can i replace with a 200kohm resistor? have replaced u7000 short gone

    The board draws 20V CPU gets warm too liquid spill on the motherboard the affected area was U8510 and c7434,c7436,c7437 are corroded... I replaced all components and no changes.. I took some readings around u8510 compared diode mode readings to good board found r8592 pin 2=BUF_SMC_RESET_L is...
