Default Ideapad 100S-11IBY NB116BT1_MB_V11 Component identification

Can anybody help me identify this component and its value? I am unable to find schematics for this board and I was wondering if there is any other way to identify. I can't see anything else near by that could be of same value. Any help would be gratefully received!

I think current is another thing to look for, but for this purpose its easy, just look for same size. You cant use bigger (will not fit), or smaller coil. Check if it is shorted, and if yes, its propably working, even if it misses a bit. I would try to change the IC.

You were spot on! I did some further testing and found a short on the main powerline and voltage injection showed up the IC. I removed it from the board and the short disappeared. I just presumed as I could see physical damage to the inductor that that was the culprit. Many thanks for your help!!
