[DEFECTIVE] Now my 2nd LPA wont power on, LED lights stay off

Latte Panda Alpha was working until 02/20/2012. Was powered on, and suddenly powered off and could not power back up. No LEDs light up. I have two, same issue with both, now neither of them work. Measured voltage of 15v from the closest to the usbc E7ET chip and ground, confirming the power supply is negotiating and providing correct voltage.
