This motherboard has no signs of life, none of the LED's light up neither the power button does something.
i measured some of the resistances and voltages:

112ohm 1.2v
75ohm 0.9vs
6 ohm vddc_vdd and vddcr_soc
13k ohm 5valw_p
3k ohm 3valw_p
21k ohm 780S_LX

voltages without a battery and without a CMOS:

3.3v at 3valw_p and +3VL_EC
3.8v at 5valw_p
9v at 780s_lx
0v at EC_APU_ALWEN, 0.9VS, EC_VR_ON, EC_ON_L (no resistor installed at RE104 so i don't know if it even should come up), ALW_PWRGD and 1.2v
