UP0104S Datasheet: A Comprehensive Guide to uPI Semiconductor's Power Management IC

The PCI_V power is generated by the UP0104S. The EN (Enable) pin of the chip was at 0V. Tracing the circuit revealed a physical resistor divider (a 222 resistor) was damaged. This resistor, together with a 162 resistor, was supposed to provide an enable voltage from a 12V source. Replacing the damaged 2.2kΩ (222) resistor restored the enable signal, allowing the UP0104S to power up and produce the correct ~1.07V PCI_V output, fixing the graphics card. Up0104s Datasheet
