Gigabyte H110M-S2 has no CPU power supply.

Motherboard model: Gigabyte H110M-S2 REV:1.0, failure phenomenon is not displayed when starting. There is no CPU power supply for measurement, and all other power supplies are normal.

The power supply chip is ISL95858. It is normal to measure VR_ENABLE as 3V. Measuring VDDP is 12V normal, and measuring VDDP is 3V, which seems normal, but it is not normal, which should be 5V. 5VDUAL is converted by DAQ5. It is abnormal to measure that the control pin of DAQ5 is 4.5V, and the control pin is 12V through 8.2K resistor. Normal thinking must feel that the resistance has deteriorated and become larger, but the measured resistance is normal. Troubleshooting of replacing DAQ5.
