HP x360 15-bk060sa liquid ingress.

[pc1staid]

Hi all,
I have a customers HP x360 15-bk060sa, mainboard Laduree-SKY 14263-1, HP part number 860591-601.
I am unable to find a schematic, but I need a little help with what I hope will be a final resolve.
The laptop as suffered liquid ingress, found a cracked cap lots of corrosion, which has been cleaned up but got a corroded pad on a component that I do not no the designantion of it on the board. I have attached images to hopefully aid someone to identify it.

The component with the damaged pad is a TPS51225 and pin 12 (VIN) has been corroded away. Issue I have is there is a via that I would assume is the feed but the track does not seem to match up to where the track of the pad goes. As you can see on the scope pics, the via has no track between it and where the pad should finish. Experience tells me by the shape I do have the correct place however not 100% sure and dont want to connect to it just in case. Hope I am making sense. Also the cracked cap is designation PC4516 and again I have no way of knowing the value of this cap.

If someone is able to let me know the cap value and where I can pick a feed for the VIN on TPS51225, I would be greatful.
Thanks in adavance for any assistance.

for the VIN TPS51225 and pin 12 you can take jumper from on of the upper fet Source side +B for the replace the cap with a higher value or what is the value of PC4525 ?

Thank you @techtiger. Unfortunatly, even with this pad repaired, there is still no power running through the board... I have put it on the back burner for the moment and will come back to it soon.
