Was it that I connected the AC charger without the battery installed that killed it? Just wondering for future reference. Thanks!

Pardon my tongue in cheek reference to Star Trek, The Original Series (ST:TOS). Yes indeed, your ACT chip is likely fried. Some models in that condition offered for parts on The Bay do show some lit LEDs, so there may be an off chance that a loose connection saved your electronics. It's worth a try if you have the case opened to trace back from the battery contacts to some exposed trace internally. I don't know enough to help but others might.

Good luck.
