[SOLVED] Can power throttling because of power IC?

[kvbkiran]

Recently my laptop is facing current and power limit throttling. Sometimes the power is showing plugged out and plugged in again when using charger . I tried every possible fix I can do from internet. I tried repasting, Undervolting, changing with power limits, increasing power limits, checking with another same charger with same ratings but nothing worked. Later I went to service center and they told to replace motherboard. They told something regarding with power and motherboard should be replaced.
im thinking if it just the power IC problem, can it be replaced?
Laptop is
ASUS GL-503GE
I5-8300H
8Gb ram
GTX 1050Ti

Laptops are always maxing our their power/thermal limits. That's why CPU frequency doesn't just sit at the max indefinitely.
