[Q] One Totally Dead - help!

I'm about to receive my 4th HTC one:
#1 - lasted less than a week before I returned it. Wiggling a headphone plug in the headphone jack caused all kinds of weirdness. AT&T replaced it.
#2 - lasted about 6-7 months. Unplugged it one morning and it went totally dead. No charge light would come on when plugged in. AT&T replaced it.
#3 - lasted less than one month. Pulled it out of my pocket while (ironically) in an AT&T store and it was a brick like #2. 5 minutes before it was working. It was charged that morning using the original HTC adapter & cable. AT&T is mailing a replacement (#4).

All had bootloader unlocked. #2 was also SIM unlocked and S-OFF. All were running (different) custom ROMs. All were in cases and had no physical or water damage (not even scratches).

Any idea what could cause this hard brick where the charge indicator doesn't even come on? Any ideas to rescue it?

Thanks!

Yeah. How helpfull... Please tell me how an S-on device can be bricked when everything is stable. This didn't happen after a ROM flash or any similar activity. Phone goes from just fine to dead without any specific action.

Curly060 - same adapter, but I use other adapters and cables as well (office, car, etc.). Custom rom was Maximus 30.0. No under/over clocking or volting.

My guess is that one of my power adapters is out of spec. I use a non-HTC adapter where it generally charges overnight.

I'll replace them all.
