Post your bios backup, the EC can probably be extracted from it. Also, post the required laptop serial number.....

Replaced KBC along with charger IC, some voltage rails are missing, but somehow I can program KBC and battery is being charged

But motherboard not powering on. Might be KBC rom issue ? Can try with another rom.

Thank you very much SMDFlea for taking time to provide help and guidance on extracting EC rom.
Further diagnose with thermal camera shows that there is a heating component (DDR4 1.2V IC) will replace it and post results here.

First KBC then charger IC, then DDR voltage chip then who knows what ? one broken chip after another, this repair wasn't conlcuded as success, returned to customer. Thank your all for helping.
