H-ig41-uatx Rev 1.1 Schematic
The H-IG41-uATX (rev 1.1), often referred to by its HP/Compaq codename "Eton," is a micro-ATX motherboard manufactured by Foxconn. While full circuit schematics are generally proprietary and not publicly released, detailed layout guides and pinout specifications are available for troubleshooting and case migration. Motherboard Layout & Key Components
- Consult Schematic: Trace the jumper (JCMOS) and the RTC (Real Time Clock) circuit near the Southbridge.
- Test: Measure the 3V battery trace. If the schematic shows a diode protecting the battery circuit, and that diode is leaky, it can drain the CMOS battery in days.
CPUs: Compatible with Intel Core 2 Quad, Core 2 Duo, and Pentium processors. h-ig41-uatx rev 1.1 schematic
Socket: LGA 775 (Supports Core 2 Quad, Core 2 Duo, Pentium, and Celeron processors). The H-IG41-uATX (rev 1
Inside the Foxconn H-IG41-UATX Rev 1.1: A Schematic Analysis
The Foxconn H-IG41-UATX Rev 1.1 is a classic Intel LGA 775 motherboard commonly found in OEM desktop PCs, particularly from HP and Compaq systems (often branded as the Pegatron M2N78-LA or similar variants). For electronics technicians and hobbyists, the schematic diagram for this board is more than just a wiring map—it is the "Rosetta Stone" for diagnosing complex power failures and bringing dead boards back to life. Consult Schematic: Trace the jumper (JCMOS) and the
Because the G41 chipset itself supports up to 8GB, many users have successfully bypassed the "official" limit by using specific low-density 4GB sticks (2Rx8), though this often requires a BIOS that doesn't artificially cap the memory map. 3. Troubleshooting via the Schematic
However, based on standard Intel G41 chipset architecture and the specific board model, here is a technical inference report detailing the power distribution, major ICs, and diagnostic points for the H-IG41-UATX Rev 1.1.
