You have 20v so believe the cd3215 are working.

21.=3.4V
SMC_PM_G2_EN comes high? = 3.4 V
Are you using 87W charger? = used 100Wsigpic
MEOWING IN THE IMPOSSIBLE UNIVERSE!

so I rewrote several options for the OS, including with a clean region, the board consumption is still = 0V, substitution from other boards also did not give anything! I installed a BIOS chip from this board onto another one and it starts it up! Apparently we need to look for the reason elsewhere (

What is the voltage to ground of the following points? Given that your PPBUS_G3H is boosted, these lines should be ok but do confirm it. Along with the current PPBUS_G3H voltage to ground.
SMBUS_SMC_5_G3_SCL
SMBUS_SMC_5_G3_SDA
After you attempt to power up, what is the current draw ? Stuck @ 0A ? What is PPBUS_G3H? Stable voltage till you unplug the adapter?
