Hig41uatx Rev 11 Schematic Patched -

: 1.25V for GMCH termination and 1.05V core voltage for the Southbridge.

The motherboard, commonly known by its HP/Compaq codename "Eton" , is a vintage Micro-ATX board manufactured by Foxconn . Frequently found in office-oriented desktops like the HP Compaq 500B series , it remains a popular choice for budget-conscious retro builders and repair technicians.

The Super I/O releases this signal to tell the Southbridge that standby power is stable.

Compatible with most Intel Core 2 Quad, Core 2 Duo, Pentium, and Celeron processors with a 775 socket.

: Shorted High-Side or Low-Side MOSFETs in CPU power phases. hig41uatx rev 11 schematic

: The Southbridge releases sleep states to enable main system power rails ( +12V , +5V , +3.3V ).

Look for the internal Foxconn code printed directly on the PCB (e.g., configurations like Go to board name formats like Formosa or alphanumeric strings starting with 15- ).

For users attempting repairs without a full schematic, the H-IG41-uATX User Manual emphasizes several critical maintenance steps:
