Last ditch: connect 3.7V (or similar) to the battery pins (TP6 3.7V, TP8 gnd), and see if it boots up. My 5V 1.2A switching PS can barely handle my board, but the battery is good enough to handle the bursts without driving the P/S into over-current protection (cutoff). My Li-Po has managed to stay at 3.9V after being plugged in for a while.
