P13USB keeps blowing after few days of use

Thanks for the suggestion. I have found a diagram from Calvin and checked every point on diode mode, they all seem to be there, but all are off by the same amount (probably due to the multimeter, wires, or motherboard model?), eg. the vcc in his diagram has 432, mine gives 370. Aux + and - on his is 740, mine are 700, and on the right side of the chip there are some that on his is 432, on mine 370. So the lower the value the more off my measurements are compared to Calvins. But all are present and seem to be off by the same amounts. (Also no resistance at all from one filter to another at 200k).

This could either mean something is bad, or my measurements are off due to the multimeter which I think is most likely. The switch is currently working, and I have been charging it through usb to computer 2.0 port (takes forever), and It has lasted all night. I am starting to think that maybe the client was lying, and did connect it to their charger. I have their charger and have connected it for small amounts of time to check for spikes on the main 15v line and the sbu1&2 lines, nothing happened. But is there a way I can be sure? I get no voltage (through oscilloscope) on the sbu1&2 lines (the ones that constantly blow), and no noticeable spikes on the 15v line.
