Asus Vivobook Flip 14 SMD identication help

[paulyboy]

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

Its an inductor,its connected to pin 6 .See page 63 of the nb8511 schematic. The layout will be similar. https://www.alisaler.com/acer-swift-...-mb-schematic/
