Default smoked my e280

Ok, it was my own fault, I was designing a custom usb charger and I swapped polarity accidentally and heard a heart-stopping little popping sound when I plugged the sansa in as a test.

The interesting thing is it works fine, starts, runs, everything, except it won't charge the battery anymore.

My hope is that I just blew the LiIon charging chip and if I swap that chip I'll be back in business. So I'm wondering if any of you know which chip is the charging chip? Of the chips I could identify none of them seem to be the charging chip.

Any other ideas are welcome.
