C1412/C1416/C1480 is on the PP_BATT_VCC line. However, there are a lot more caps on that line than just those three. You will have to search through the schematic to find all of them and you will want to test them all. Of course, the problem could also be within Tigris itself so you'll have to decide if you remove that first or last.
