Use a multimeter in continuity mode. Check the low-side MOSFETs and decoupling capacitors near the main current-sensing resistor ( PWRSRC ). Fault 2: Dead 3.3V/5V Always-On Rail
The PCH responds by pulling sleep signals high, instructing the board to activate the RAM power rail (+1.2V) and the secondary run rails (+1.05V, +1.8V).
Before checking complex signals, ensure the main power rail is distributing voltage across the board. laf952p rev 10 boardview exclusive
Ensure your boardview explicitly matches Rev 1.0 . Schematic variations between Revision 0A, 1.0, and 2.0 often involve entirely different component position indicators and power rail mappings.
