I am working on "power rail error". No shorts, spill liquids, visible damages. Just a pure failure somwhere. So, where did I get to?
if you look at page 5, there is a power sequence diagram. All measurements up to sequence number 19 are ok. The process stops at sequence 20 PCH_THERMTRIP#. The PCH is separate and operates normally on power 3.3V ALW and 1.8V ALW. Where is the hack?
