Use your schematic to locate the phase coils (inductors) next to the CPU socket. Measure the voltage while the board is switched on. If VCORE is 0V but the fans are spinning, the PWM controller is missing its enable signal, or the controller itself has failed. Missing BIOS Voltage
: Compatible with Intel Core 2 Quad, Core 2 Duo, and Pentium processors. h-ig41-uatx rev 1.1 schematic
Once you've obtained the schematic, understanding it requires some knowledge of electronic circuits and symbols. The H-IG41-UATX Rev 1.1 schematic will include: Use your schematic to locate the phase coils
A known failure point is the main Intel IC getting excessively hot, which often indicates a short or power delivery failure. Missing BIOS Voltage : Compatible with Intel Core
The Rev 1.1 iteration of this board maintained the core architecture of the Foxconn Eton design while ensuring component compatibility for HP OEM systems. It is characterized by its green PCB and support for a wide range of Core 2 Duo/Quad processors.
