The power supply of the mainboard power management chip is usually 12V or 5V. If the power management chip is damaged, the motherboard will not work.
Common motherboard power management chip models are:
1. HIP6301. HIP6302, HIP6601, HIP6602. HIP6004B. HIP6016 of the HIP series
HIP6018B. HIP6020. HIP6021.
2. rt9227。RT923l。RT9238。RT9247。RT9713。rt9774等。
