[Q] Droid Incredible 2 won't turn on or charge.

I have had this problem before, right after I got the DINC2. Yesterday, I wanted to take out my memory card to save pictures on my computer via a usb card reader. I turned my phone off by pressing the power button and selecting power off. I removed my battery, and then removed the memory card. After transferring my pictures, I placed the memory card back in the DINC2, and placed the battery and cover back on the device. I pushed the power button, and NOTHING. The phone won't turn on. I plugged it in to the charger, and the amber light won't even come on. I thought it might be the charger, so I used the USB cord attached to the computer, and still no charging light. I have removed the battery overnight, and just let it set. When I reinstalled the battery this morning, still nothing. The charging light does not come on, and I can't power up the device.
I had this problem before. I had let the battery run down to nothing and the device powered itself off. Same scenario, the charge light would not come on when plugged into the charger, and I couldn't power up the device. I left the battery out overnight, and the next morning the device still wouldn't power on. I placed the phone in my car, and plugged in my car charger. After a few minutes, the amber light came on, and I was able to power up the device. This, however, did not work this time. Nothing I try helps.
Is this a common problem? How should I go about getting this resolved?
Update: I called Verizon CS, and they are shipping out a new (refurb I guess) device. The rep had never heard of this either. Strange indeed.
Thanks

Plugging in usb cable will automatically start phone

I've been going nuts with this problem, that if the phone is being charged with usb cable plugged in, when I press "Power off" the phone will shut down and automatically restarts itself.
If I unplug the cable the phone can power off fine, but when it's in power off state, as soon as I plug in the cable, it starts itself automatically just as if I pressed and held the power button which I didn't.
What's going on?????????? Please help.
Clarify: it's not that the screen turns on, it's the phone actually turns on / boots / starts.
EDIT:
Did a little research, my problem is the same as here:

I noticed with mine, the only time it started up automatically was when I didn't have the USB cable plugged in fully to the wall charger.
I think that the phone can somehow detect either resistance or capacitance changes in the USB connection and turns on under certain circumstances, while it is supposed to stay off if the resistance / capacitance values are "normal".

it's normal for the screen to turn ON when you plug in the USB cable
it's NOT normal for the Phone to turn ON from OFF when you plug in the USB cable
the normal behaviour for when the Phone is completely OFF when you plug in the USB cable it should just show you the green battery meter charging

The phone turns on.

maybe it's a defective unit?
have you tried going back to stock?

I doubt it's a defective unit because it used to be fine. Just happened yesterday.
Everything is stock right now.

try a different charger/cable. if it still happens return it.

I had this problem after wiping my battery status and draining it all the way down. After charging over night, I then ran battery calibrator the next day and when i ran it all the way down again and plugged it in the problem was solved. Hasnt happened since (since 2 days ago when this happened anyway).

very interesting

Mine turns on when I plug in a usb cable while the phone is turned off following a battery stuck at 100% condition. In other words, if my phone is stuck at 100% (usually every time after charging), and I turn the phone off, and then plug in the usb cable, the phone will turn on by itself. But if my phone is not stuck at 100%, and I turn the phone off and then plug in the cable, I get the green battery.

Moto 360 Won't Turn On Or Charge

A couple days ago it was working fine, however I noticed it gradually charged slower and slower to the point where, even when it's on the charging cradle, it loses charge. Now, whenever I put it on the charging cradle, the screen won't even turn on, and the device will not power up. The light on the bottom of the charger lights up, but the device receives no charge. I'm using the default Moto 360 connector cable, and I've even tried more powerful adapters, but still nothing. I decided to listen to any advice I might could get here before I call Motorola support.

my moto 360 is not turning on . can anyone troubleshoot this issue?

Mine got stuck in a discharge loop, was discharging on the charger, the charger was not recognizing the watch (charger light off).
The direct usb connection powered on the watch but did not charge it. No leaving it on/off the charger worked. It was dead.
The fix was to take it apart and unplug/replug the battery. It started charging normally afterwards. Now it won't stay closed, and the face keeps coming off, I press down on it from time to time and maybe I'll use some superglue

Couldn't we talk to Motorola about this? Shouldn't this be considered a manufacturers defect?

I talked to Motorola support, and after hours of phone calls, they said they would replace mine for free. But because the watch was in such high demand, I couldn't get a replacement watch for like 2 months. They seemed shocked that the device had stopped working, and it seems there aren't too many cases of this happening. I'd recommend calling Motorola support before doing anything drastic like taking apart the device.

I don't have warranty, so I can't call for help.
Mine got stuck while trying another Qi charger, so I guess only the charging chip got crazy, the watch worked normally until it drained the battery.
The charger has 2 modes: low power to signal the device it's on the charger then the device (be it phone or watch) should signal back to the charger it's present and the charger goes on the high power output to actually charge the device.
My watch had the charging chip blocked so it didn't signal back to the charger which remained in the low power state and did not provide enough power to charge the watch.
Factory reset and even USB reset did not reset the charging circuitry, only a hard reset by pulling out the battery did the trick.
By the way to take it apart it's not needed to remove the dreadded cracky plastic back, only hold by the strap and rock the case upward/left/right. Tough fingernails and a little help from a plastic wedge near the button and in the opposite side did it.

LG G3 Won't turn on after screen replacemt. (Mystery ground? enBattery dead?)

Hi everyone,
Replaced the screen on my LG G3, and now it won't turn on. Before I removed the screen, the battery was completely dead and I let it sit for a week and a half completely dead. I tested the battery with a multimeter and it shows about 2.7V across the + and -. But, the other terminals, it shows between 2.2V and 2.5V. When I plug the phone in now, there are no LED lit or anything. I tried just plugging the motherboard into a wall charger and even still, no LED lights. Oddly enough, though, I plugged the old screen back in(As well as the phone charger) and the backlight came on randomly for a second when I pressed the power button. The backlight wouldn't come back on again until i removed the power from the wall and the battery. It also helped if i unplugged and replugged the screen. It was very random. I am thinking that the motherboard grounds to the frame or something and I missed something on the install. Any thoughts? Thanks

I have no idea what is going on here.

I recently bought my Zenfone 2 from Gearbest and when it came, I let it charge a bit. I eventually got it to boot with about 8% of a charge. I then left it for a while when I did something. When I came back, I found my phone to be shut down and when I tried to boot it up, it shown a low battery icon. Very weird since it was plugged into my PC the entire time.
I then started the phone once again. But when I pressed the power button, it shut down instead of sleeping.
I repeated turning it on a few times. Every time I pressed the power button to make it go to sleep, it instead shut down. Eventually, it stopped booting entirely. There is no vibration, indicator light, or screen. When I plug it in, the top half of the phone heats up significantly. I have had no luck trying to revive it.
I have tried:
Letting it charge for about an hour.
Disconnecting and reconnecting the battery.
Pushing both volume and power.
The phone is running pure stock as I only had about 30 minutes of total screen on time.

Your pc probably isn't supplying enough power. Use a dedicated wall charger.

When I originally plugged into my PC, it was charging. I have also moved to the wall charger that came in the box.
