Hig41uatx Rev 11 Schematic [verified] Jun 2026

: If shorting the power button does not pull the line down to 0V at the ITE IT8720F Super I/O pin, either the Super I/O chip is defective or a standby resistor has blown open. Symptom 2: Fans Spin but No Display (No Post)

A typical motherboard schematic is divided into "pages" or block zones. When navigating the HIG41UATX Rev 1.1 diagram, expect to follow this structured visual hierarchy:

| Category | Specification | | :--- | :--- | | | Foxconn H-IG41-uATX | | HP/Compaq Name | Eton / EtonL | | Form Factor | Micro-ATX (24.5 cm x 24.5 cm / 9.6" x 9.6") | | Chipset | Intel G41 Express | | Socket | LGA 775 (Socket T) | | Front Side Bus | Supports 1333/1066/800 MHz | | Memory (RAM) | 2 x DDR3 DIMM slots (240-pin) Supports up to 8GB of non-ECC, unbuffered DDR3 memory Speeds: DDR3-1333 / 1066 / 800 | | Integrated Graphics | Intel GMA X4500 (VGA port on back I/O) | | Expansion Slots | 1 x PCI Express x16 2 x PCI Express x1 1 x PCI 1 x PCI Express x1 minicard socket | | Audio Codec | Realtek ALC662 (6-channel HD Audio) | | Network (LAN) | Realtek RTL8103EL (10/100 Ethernet) | | Internal Connectors | 1 x 24-pin ATX power connector 1 x 4-pin ATX power connector 4 x SATA 2.0 (3Gb/s) connectors 2 x 12V fan headers (CPU & system) 1 x 9-pin header (Power/Reset/Power LED/HDD LED) 2 x USB 2.0 headers (supporting 4 ports) 1 x 9-pin audio header 1 x SPDIF out header | | Back I/O Ports | 1 x VGA port 4 x USB 2.0 ports 1 x RJ-45 LAN port 1 x Line In (light blue) 1 x Line Out (lime) 1 x Microphone (pink) | | CPU Support | Core 2 Quad, Core 2 Duo, Pentium Dual Core, Celeron (95W Max TDP) |

: Common failure points on Rev 1.1 boards include bulging capacitors or loose power connections.

Since an official schematic is so difficult to find, your best path forward is to leverage collective knowledge from forums and communities. This approach has proven successful for many people attempting to repair or modify these boards.

Unstable operation under load, spontaneous reboots, or a complete failure to generate VCC_CORE .

Look for high-side and low-side pairs next to the grey or black chokes (inductors). Shorted MOSFETs are a primary cause of a board failing to spin its fans. 3. Memory Power Rail (VCC_DDR) : If shorting the power button does not

: Standard 10-pin (9-pin populated) HDA audio header for front panel jacks. Documentation and Downloads

With microcode-injected BIOS, Rev 1.1 can run LGA 771 Xeons like the E5450.

If your HIG41UATX board turns on for a split second and dies, or spins its fans without initializing video, tracing the power-on sequence on the schematic will pinpoint the failure node. Step-by-Step Initialization Logic

But when one of these boards fails—typically due to bloated capacitors, dead voltage regulators, or failed power sequencing—the becomes the single most critical document for repair. After an exhaustive search and analysis of available resources (official, leaked, and community-scraped), here is my comprehensive review of this schematic’s availability, quality, and utility.

Understanding the physical layout and chipset routing is the first step in decoding the HIG41UATX Rev 11 schematic. The board uses a standard Micro-ATX (uATX) form factor, though custom OEM mounting holes may be present.

The board supports a wide range of Intel Core 2 era processors with a Thermal Design Power (TDP) up to . Foxconn H-IG41-uATX (REV:1.0) - The Retro Web

This board uses the , including the G41 Northbridge and an ICH7 Southbridge. It is part of the LGA775 platform, which was known for supporting a wide range of Intel processors.
