This 3435 came in dead. Upon opening i see a burned hole in the battery. Disconnected battery but still not turning on on AC. Checking PBUS is only 0.9V. Q7560 getting extremely hot. After replacing Q7560 PBUS is 8.6V but still not turning on. Now PP3V3_S4 is missing (along with S4_PWR_EN and PM_SLP_S5_L). So checking PP3V3_S5 is 3.33V but resistance is only 18 Ohm to GND(!) I removed L7560 to see which side has this low resistance. Upon removing L7560 I see it has also been very hot because it has a little burn mark under it. The 18 Ohm resistance is on pin2 side of L7560. I injected 3.3V into this pin and ramp up bench supply to 10A. But nothing getting hot and only drawing 0.4A. So I got a "semi"-short and I don't know how to find it.
