Re: need schematic dell lattitude 3380

The shape look like ic supplied for USB or HDD/ODD, but not sure 100%. Maybe Silergy's IC (similar or new revision for SY6288x), trace the pin out. Probably input connect from 5V_S0 and output connect to SATA / USB connector.

The position near grey coil 1.0 uH make me doubt that it is IC for supply USB or SATA. that rails is too far for any USB or HDD conn.

I have question on photo that part was marked red rectangle, Does it same marking code AHU7JA?

EDIT: Forgot attached pics
