    I've disassembled the whole notebook, I'm only working with the motherboard and the power supply. When I put the power supply on the DC jack I realize that the PU4503 gets so hot that I can not leave my finger too long in it. I measured the resistance on smd capacitor PC4528 and PC4529 and it is providing me with a resistance of approximately 2.2 ohms. I have already removed both and continues to provide me this resistance measurement on the motherboard. Is the defect not in the PU4503 itself?
