Hig41uatx Rev 11 Schematic -

Board revisions often change minor components—resistor values, capacitor placements, or VRM configurations. If you are troubleshooting a Rev 11 board using a Rev 1.0 schematic, you might find discrepancies in the voltage regulator section. Always try to match the revision to avoid chasing ghosts.

One high-side (PH6030AL) and two low-side (PH4030AL) per phase.

| Symptom | Check in Schematic | Common Culprit | |---------|-------------------|-----------------| | No power (LEDs off) | +5VSB rail → I/O controller Vcc | Shorted ceramic cap on +3.3VSB | | Fans spin, no POST | PWRGD_ICH (pin 32 of ICH7) | Missing 1.05V PCH PLL voltage | | Random resets | CPU Vcore ripple → PWM controller’s COMP pin | Bad electrolytic cap on Vcore output | | No sound but audio driver installs | ALC662’s AVDD (pin 4) | 3.3V_AUDIO missing due to blown inductor | | USB ports dead | +5V_USB from APL3511A power switch | Enable pin (EN) floating due to solder crack |

The Southbridge issues PLTRST# (Platform Reset) to the Northbridge, which subsequently releases CPURST# to the CPU. The CPU then begins executing code from the SPI Flash BIOS chip. 4. Common Failure Points on the HIG41UATX Board
