eg 530 nm-b671 rev 1.0

I do have 3.3 and 5v low power near PU402 (on 2 condensators below coil PL402) but no 3.3v on 32 pin JKB1 connector. Keyboard has built in power switch, motherboard doesn't power on.

I also just posted a request for schematics

Check whether you have voltage on NBSWON#/DNBSWON# pins of sio.

You can look up the SIO pins from another schematic with same SIO. You have the mb in your hand. Why not read the sio number and find out another schematic with same sio?? Remember, you cant get schematic for each and every mb-so need to struggle a *******nt give up when i know you can.
