Neweuser: I just thought of one more thing to try before you give up on the 7i. I know you measured the power supply DC voltage and it looks good, but what about the AC voltage? There could be a filtering issue and AC "ripple" could be causing weird things with the charger. The AC might be too high in frequency to measure with a cheap voltmeter (unless it was a "true RMS" meter), so maybe hook it up to a car battery and try charging something? Can't get any closer to DC than that! Don't run the engine though for the test.
