Inspiron 3537 coil

[JJR]

Hi
I've got a Dell Inspiron 3537 laptop in that powers for a few seconds and then turns off. There is a small coil on the motherboard with a chip off the corner.
The board is a Compal LA_9982p-R3.0, the chip is LX9 and the schematic names it as '4.7UH_PG031B-4R7MS_1.1A_20%'
I've looked on every old board that I have & can't find this chip, there are no markings on the chip at all.
Does anyone know where I could find one?

LX9 is a coil. Its connected with display controller RTD2136R. You can use any coil that fits the size, even coils which looks like smd caps. Any coil will do for testing purpose.

I replaced the coil with a similar one this morning but get the same issue, tested the original off the board, it's fine. It must be a different problem that I can't see, I'll keep checking.
The customer has bought a replacement from me and said I can keep the old laptop for spares.
