C7373 and C7372 are too close together for you to know which you actually touched with the screwdriver. Before you buy chips, you should have a schematic and a boardview, which will allow you to answer these following, elementary questions(and no I don't provide this, but google does) Measure for PP5V_S5 and PPBUS_G3H. You should have 5v, and 12.6v respectively. You shorted one or the other, before you go ordering $@$* make sure you order what you need. If you buy a TPS51125 and what you sparked was PPBUS_G3H, that is a waste of time. The parts you circled are too close for you to have a reasonable idea of what you actually touched without actually measuring. One is a supply capacitor to TPS51125 for its input 12.6v(PPBUS_3H), the other is a supply capacitor for PP5V_S5 which is created by an LDO inside the TPS51125 and used as a reference for creating PP5V_S3. Also your board is not 820-2565, that is the number for the charging port which is the same for every machine from 2009-2014. Give number of actual motherboard so you can find proper schematic & boardview.
