I’ve got this Ideapad 720s laptop to fix it has no power or charging so immediately after disassembly I found a cap that looked burned, and on the other side of the board a layer was found in this state.



I believe this is the main power rail as it is on the battery input mosfets. When I plug in the charger and nothing else there is small sparks when it is pressed with a plastic spudger (oh god).

I have taken pictures of the burned area and also removed some capacitors on the reverse to have a better look

Can I peel and scrape away the short? The layer must have burned into a ground track inside and this could then be repaired with wire
Thank you for any help!

I actually did manage to cut away the shorted pads you see here! Only problem was there was another short elsewhere on the board

That whole area around the damage looks like it has issues you have several burn marks there, plus removing the damaged parts or cleaning the area won't repair the traces in the PCB.
I'm telling you that I fixed the problem there, there were no damaged traces, just the pad, which was able to be cut out where damaged and still leave behind working copper pad.
