Ok back to this board now.
The status now, we have all signals and voltage present except that, no chime, no display USB blinks when inserted caps lock does not light up, power button works fine.
Charger starts with green then switches to orange with and without battery present. ppbus_g3h is at 8.1V does not change to 8.4V
inspected all lines that could potentially lead to why there is no chime but could not find any, the SMC seems to be functioning correctly. i also dont have a TBT_A_HV_EN thus L3095 is not showing any voltage. I thought I have a problem with U2800 because its the one that sends that enable signal, but I also think it should not be the case I have no shorts around that circuit.
The LPC_FRAME_L and LPC_FRAME_L_R are both present and I have activity on LPC_AD
SPI also shows some activity after few ms of time.
Any ideas to know what is wrong here?
