Clean board, no corrosion.

All test were done on bench nothing connected except for IO board and flex, I tested it without flex too and same problem.

Board has 1.8V PPVCC_S0_CPU
CPU gets hot as if it is working, tries to boot but stays around 0.150A
PPVRTC_G3H 3.3V
PLT_RESET_L 3.3v
U7100 27-28 and 17-18 measure normal

Already tried heating up CPU, clean BIOS on a new U6100, Working SMC but same problem.

Sheet 11 is all could find, somehow page 11 is missing in my schematic if by page 11 you mean PCH Decoupling page all voltages from that page are present and correct.
