8125 Won't Turn On... Worrying

Yeah, my 8125 won't turn on at all. No dice with the "hard reset" in the manual, no dice with plugging it in to USB [though on a Mac] or [Motorola brand] AC charger.

I think I may have run the battery out completely... because it was off when I came back to it on my desk, and when I started it up, something flashed on the screen about 'safe mode' before it went black again... now there's no response from anything. It should still light the orange LED up when I plug it into the AC, right? I got nothing.

make sure you use the HTC charger. I've had a couple units go dead DEAD and they took a while to come back to life when on the charger. Good luck

Could also take the battery out and reinstall it. If it is only locked up, that should clear that out.

Well, I am having the same issue right now. I used the 8125 this am. At around 10:20 I tried to make a phone call and it would not turn on. I took the battery out and reinstalled it,,,nothing. it has been on the charger now for 4 hours........ REST IN PEACE TIME........
Anybody have any ideas

You must use the original AC adapter if your battery is deeply drained. All other charging solutions only works when battery is not deeply drained. The reason being it needs far larger initial power surge that only the original charger can supply.

I had the exact same problem. I charged the phone all night with original charger. in the morning it didn't come on. I removed the battery and put it back and everything was cool. didn't lose a thing and it has been working great since. battery life and the ramifications there of are my only complaint with the 8125 so far.

Yeah, as it turns out, Foxbat was right... HTC charger did what Motorola's couldn't.

So now, techheads, I ask: obviously there's something besides just electrical circuits that goes on in the charging process... but AC adapters don't have firmware, obviously. Why does HTC's charger work when another one just like it doesn't?

HTC charger is rated 5V 1A. Does your motorola has the same rating? USB ports can only offer 500mA max. My guess is that if the battery drops to a critical level, it needs around 1A of current to start charging.

My previous SMT5600 smartphone behaves the same. So its HTC specific requirement.

That is precisely the difference, haha... Moto is half an ampere, HTC's is twice that. (But that's why I'm a lawyer not an electrical engineer...) Learn something new every day, I guess
