Laptop freezing on load

Hey! I have an ASUS TUF FX504GM laptop, which was working flawlessly until last week. I don't know what happened, but seems like there was a power surge after which my laptop froze and smoke was coming out from near the fans. I immediately removed all connections and manually forced shutdown by holding the power button. I let it cool for sometime. After that I opened the back cover, only to discover one of the IC was burnt completely and the laptop was not able to charge.
I contacted nathan at best buy geek squad phone number he suggested to replace the ic and the charger.
After implementing these changes the issue was resolved and now it is working fine without any issue.
