Default Asus Vivobook Flip 14 SMD identication help

Hi Team,

I have a laptop motherboard with a blown IC, there was no ledgable print on the IC and currently the board ID TP412UA has no supported boardview or schematic!.

I very stuck and the pad layout is unlike any I have seen before.

Could anyone be so kind to share the knowledge.

Kind regards

Paul
