Hig41uatx Rev 11 Schematic Verified -
We cannot host copyrighted files, but we can tell you that a verified HIG41UATX REV 11 schematic will have these characteristics:
The HIG41UATX (often labeled as “Higos” or generic OEM) is a standard Micro-ATX motherboard featuring:
The REV 11 designation is critical. Previous revisions (REV 10, REV 1.0) have different resistor divider networks for memory voltage detection and different PCIe clock routing. Using a REV 10 schematic on a REV 11 board will lead to misdiagnosis of power failures.
The air in the workshop was thick with the scent of ozone and stale coffee. Elias sat hunched over the HIG41UATX Rev 1.1
motherboard, a relic of a specialized industrial system that had gone dark three days ago. Without it, the plant’s secondary cooling array was a multi-million dollar paperweight.
He had spent forty-eight hours scouring archived forums and dead FTP servers for the one thing that could save him: a verified schematic. Most of the diagrams online were for Revision 1.0—different voltage rails, different headaches. But then, tucked away in an encrypted thread on a legacy engineering board, he found the file: HIG41UATX_REV11_FINAL_VERIFIED.pdf.
With the document pulled up on a flickering CRT monitor, the mystery began to unravel.
The Ghost in the Rail: The Rev 1.1 board had a subtle change in the +5VSB (Standby) circuit. The verified schematic showed a decoupling capacitor, C142, that wasn't present in the earlier designs. Elias looked at his board; the cap was there, but its casing was slightly discolored—a microscopic crack only visible under the jeweler’s loupe.
The Surgical Strike: Using the schematic’s pinout map, he traced the fault. The failed capacitor was pulling the power-on signal to ground, tricking the board into thinking it was constantly being shut down. hig41uatx rev 11 schematic verified
The Resurrection: He desoldered the faulty component and replaced it with a high-temp alternative. When he flicked the bench supply switch, the board didn't just hum; it roared to life. The diagnostic LEDs cycled through their sequence and settled on a steady, triumphant green.
Elias leaned back, his eyes burning from the strain. In the world of high-stakes hardware repair, a "verified" schematic isn't just a map—it's a miracle. He scribbled a single note on the motherboard’s heat sink before packing it for the plant: Rev 1.1 Verified. Stable.

If you share what type of device this is (e.g., ATX power supply, motherboard, or other), the connector pinout, or the controller ICs on board, I can help you identify common reference circuits to compare against.
The H-IG41-uATX (Rev 1.1), often referred to by its HP project name "Eton," is a micro-ATX motherboard manufactured by Foxconn for various HP and Compaq desktop series, such as the HP 500B and Compaq Presario CQ3000. This revision is a classic "bridge" board from the late 2000s, combining the legacy LGA 775 socket with then-emerging DDR3 memory support. Core Technical Specifications
The board is built around the Intel G41 Express chipset paired with the ICH7 Southbridge.
Processor Support: Supports LGA 775 socket CPUs including Intel Core 2 Quad, Core 2 Duo, Pentium Dual-Core, and Celeron. It accommodates 45nm microarchitecture and can even be modded to support LGA 771 Xeons with BIOS updates. We cannot host copyrighted files, but we can
Memory: Features 2 x 240-pin DDR3 DIMM slots. While officially rated for a 4GB maximum (2x2GB), some users report the chipset can physically handle up to 8GB if specific high-density modules are used.
Graphics: Integrated Intel GMA x4500 graphics via the VGA port. Note that integrated video typically disables automatically if a discrete card is installed in the PCIe slot. Layout & Connectivity
The schematic layout of the Rev 1.1 follows a standard micro-ATX (uATX) footprint (approx. 24.4 cm x 24.4 cm). Expansion Slots: 1 x PCI Express x16 (for graphics). 2 x PCI Express x1. 1 x Standard PCI.
1 x Mini PCIe slot (often used for wireless cards in OEM builds). Storage & I/O: 4 x SATA II (3Gb/s) ports.
Rear Panel: 4 x USB 2.0 ports, 1 x RJ-45 Ethernet (Realtek RTL8103EL), 1 x VGA, and 3-port audio jacks.
Internal Headers: Two USB 2.0 headers (supporting 4 additional ports) and a 9-pin front panel header. Power & Thermal Management Foxconn H-IG41-uATX (REV:1.0) - The Retro Web
