Laptop tries to turn on, fans spin for 1 second, dies. Diagnosis: The motherboard is hitting a missing power rail. How the schematic helps: Flip to page 35 (Power Sequencing). Look for PG (Power Good) signals. The SYS_PWROK signal must flow from the +1.0V rail to the EC before the CPU will release PLTRST# . Fix: Using the schematic, probe +VCCIO (usually near CPU socket). If missing, check PU18 enable pin (Pin 7 – EN) which comes from SUS_ON . If SUS_ON is low, the EC is stuck. But not for free
