Hig41uatx Rev 11 Schematic |top|

If the schematic’s "VTT_EN" signal is missing (often a blown resistor on the enable pin), the CPU VRM never turns on, resulting in a "fan spins, no POST" fault.

A schematic, or circuit diagram, is a diagram that represents a circuit electrically. It shows the components of the circuit and their connections, using standard symbols to represent the components. Schematics are used to make it easier to understand the function of a circuit, to design and build it, and to troubleshoot any issues that arise. hig41uatx rev 11 schematic
