LG P920 just boot when plugged to charger - LG Optimus 3D

the problem is just that, the phone boot just when pugged to charger, original or any charger, or PC USB, or just anything that give current via he's own osb port
power button doesn't work anymore (from near 3 years I need to go out with a emergency charger and a short usb cable)
this problems starts near 3 years ago, some day the phone goes crazy and boot loop several times, from just LG logo to scanning multimedia files, or start perfectly, but shutdown any time, or just work good several days (and with the power button working)
I was thing on humidity or moisture, but the mainboard seems to be ok, one day I was soldering two wires, and when de power button was working putting together the two wires acts like power button, but when power button doesn't work the wires the same
some day recently I was cut away the power button flex, test it and it's broken, but the two wires doesn't work
the very problem is that now the shutdown is most noticeable, no matters if I put just the original stock battery or other original, those batteries are ok, old but ok, charged and the voltage are ok
there is some with expertise to guide me to find how to resolve this?

Triumph won't charge

I got my Triumph and it will not charge no matter where I have plugged it in or fiddled with the charger. It does not matter whether it is on or off. I have been using the wall charger that's included and I have tried USB through my computer. Before I go to the hassle of sending my triumph back I wanted to see if there is a solution. Thanks in advance.
The first one I got did this sometimes as well. I took it back and swapped it.
Jumpstart
My triumph would not even turn on strait out of the box. I had to "Jumpstart" the battery, here is a link on how to do it. thejosea.com/2011/02/jump-start-your-droid-when-no-wall.html (Sorry i cant post links yet, gonna have to copy paste)
You pretty much have to charge the battery by its self outside of the phone. Once you do this let it sit charging for about 20 minutes then try to charge it through the phone.
You should only have to do this once.
It seems like the batteries are not being shipped charged and they run "Dry".
You MIGHT want to try a different USB cable.
I'm using my Nook Color adapter(1A) and a generic USB cord which works fine, however one time I accidentally used my Optimus V cable and it would NOT charge while the MT was up and running, however it WOULD charge IF I powered down the MT...
I haven't even tried the cable that came with MT yet... nor have I tried charging via a USB port on my nb, but I imagine that would be REALLY sssslllloooowwwww....
I exchanged my device for a new one, and with my new phone, when plugged in, the lock screen no longer shows "Chargin" with the %. Any ideas how to bring it back?
It only shows that if you're on an AC charge. If you're on USB it won't.
I've tried on 2 different AC chargers and it still doesn't display
Same cord? The AC pins have to be shorted or it won't go into AC charge mode. I have a couple of USB cords that work fine for connections to the computer but will not go into AC mode (the USB cords that come with the Optimus are known for doing this on other phones, incidentally....)
It'll charge without AC mode being "engaged" but at the 500ma rate instead of the 1A rate, so it will take a lot longer.
the answer is simple.....due to crappy crappy design of micro usb the charge port actually comes un-soldered from the board and obviously it no longer will charge nor will usb work!!! now before you ramble on with how do i know i wondered why mine wouldn't worked i opened the phone and notice the micro usb pins were not attached anymore....i have sent this in to Motorola which gives you a 2 year warranty instead of virgin mobiles crap $5 a month insurence then you still have to pay like $100 to get a new phone!!! so i will post how everything goes so far i know the repair center is in McAllen TX and they give you a free 2day shipping label valued at $100 to send in the phone!
You might want to try plugging it into a wall (not pc) and leave it for 20 minutes. Mine ran completely dry one time and it wouldn't display nothing until it charged for a while. If you've already tried this then definitely take it back.

*update* They are fixing my phone now and i should get it in 5-7 business days no problems they received the phone and started the repair
I had the same problem but different solution.
I too let my phone completely discharge to find that it would not indicate that it was charging or even power on with or without the battery being present, but I "jumped started" my phone. This is a weird technical solution that went as followed in its entirety, meaning, some of these steps might be pointless or useless but I did them and I now have a working resurrected MT in my hands that is charging. This solution is assuming that there is no problem with the micro USB soldering on the main board.
"Jump Starting"
1) Remove the back casing and your MT battery and place both to the side, but keep the battery close by for polarity reference.
2) Have another battery of the same 3.7v that is charged (disregarding mAh).
3) Now here is the fun part and pay CLOSE ATTENTION to POLARITY!!!
-Get two spare wires, preferably of different colors so you can tell the [+] from the [-].
-With the spare 3.7v battery you have, in what ever way you can, connect your spare wires to it, paying close attention to polarity.
-Now that you have your spare battery wired, CORRECTLY connect the wires to the inside connectors of your MT what ever way you can, paying close attention to polarity.
Being [+] connected to [+] and [-] connected to[-]
4) Boot your phone until you know you are at the home/lock screen. Then remove the wires from the MT battery connectors.
5) Use this same battery and connect it to your battery for about 30-60 seconds, paying close attention to polarity. This will give the battery some juice for the system to recognize.
6) Place the battery back in the phone without attempting to turn it on and return the back case to the closed position.
7) Now connect your MT to a powered micro USB cable and see if the red indicator charging light turns on.
-If so then great!
-If not then you may have some other problems
-If yes and no, as in the cable has to set a certain way for it to charge then just keep on reading for that fix as well.
"Loose Connection Fix"
This is how I fixed my loose micro USB cable and it worked for me, but I do not have soldering problems on my main board of my MT so proceed if you think this will help.
1) Your micro USB male side of the cable that plugs into your MT should look something like this (excuse the crude drawing of letters)
{the dots are empty space}
____________
\................... /
\UUUUUU/
2) Get a pair of needle nose pliers and SLIGHTLY pinch/squeeze the center of the male port closed so it looks like this
____...... ____
\.... \...... /.... /
\UUUUUU/
Except not that extremely bent inward, but you get the idea.
This will force the male tongue in the MT charging port to be forced onto the pins inside the micro USB cable for a better connection and thus fixing the loose connection problem
I hope this helps someone, it helped me save my $300 paper weight from actually being a paper weight.

I let my battery die down and also did a battery memory reset, then the phone acted bricked.
Then I tried this to revive and it worked!
Thanks for the help here I did this but when I connected the batter to the phone nothing happened. I connected battery to battery let sit for about 90 sec put it in phone and plugged in and the red light is now on!
Thanks!
Well,
add my phone to the list. It started about 2 weeks ago when after completing charge, instead of maintaining trickle charge it just let battery drain. I woke up couple of times in the morning finding the phone's battery on it's last legs. Now it simply refuses to charge by anything but my car charger. Lucky for me (and I thought I would never say it in my life) I have a long commute to work and it allows me to recharge the phone while I enjoy typical traffic delights.
I am going to call Motorola and discuss my options with them. I hate doing this as my phone is long since rooted and running CM7, so I will probably have to revert to factory settings before sending it off and if they decide to exchange I would be running a chance of receiving one with bad GPS.
yes i've had this problem to i have to charge my phone on a Samsung charger no motorola charger will work on my phone.
Sorry, I'm somewhat new here.
I have a Motorola Triumph and it just stopped working. The general idea is that the Micro-USB port was shoved up into the device?
How do you go about contacting Motorola about sending it back to be repaired?
I have delt with this problem SO MUCH, have you tried my battery charging fix yet ? I have the link posted in this section called battery charging fix, Hope this helps you it sucks when your phone won't charge.
Well the problem is that it won't even turn on. I think the battery has some kind of charge but when I hit the power button, it vibrates like it's booting up then stays off.
I don't know that much about phones, but from what I can gather off Google and the various threads on XDA (Great site, by the way!) the general consensus is that it's the micro-usb port.
Granted, I may be wrong, which is a very real possibility. Heh.
Well 2 things, have you replaced your recovery with the clockwork recovery image ? If so try any means nessary to get into recovery, My old Triumph would NOT charge with any motorola charger, I belive this is a defect with the triumph. You might try a powermat of some kind to get enough power to get to recovery & do what my guide says to fix this most pain in the ass problem, Or get another battery & follow the guide. It's worth a shot anyway. otherwise you've got two options replace it or open it up, if you're gonna open it up then get a super fine sautering tip or file one down to needle size, this is how I do precision sautering on circut boards.
No, I had downloaded Clockwork with the intention of installing a 2.3 rom on it, but never got around to it. As for the charger, my Triumph charges with any micro-USB, from my old LG and Samsung chargers to the Motorola charger that came with it. It acts weird though when I plug it into a computer, saying it is connected to a computer, then that it's not, then that it is, then that it's not, repeatedly. I usually just end up turning it off so it won't do that.
I find it weird, though, that now when I try to charge it, the charging light up where the speaker is will not come on, as if it isn't charging. (And I don't think it is charging.)
I've also tried putting it into the "recovery mode". (Like I say, not too knowledgeable about phones yet. Learning experience. ) When I boot it up (into "recovery mode" or "regular" (?) mode) it just vibrates like it should then does nothing.
Edit: It finally did boot into the "recovery mode", but the touch button things at the bottom (menu, home, back, and search) don't do anything, and I cannot get into the menu to do a factory reset.
I don't think it's the battery now? I am more confused then I was when I started, and appreciate any and all help!

HP Touchpad CMx will not charge (bricked) solution

After many successful upgrades to Android I finally got the kiss of death. The battery died and it would not recharge. After many hours of research and trial and error I was finally able to get it charged again. I had read to let it sit for a week and let it totally discharge but me impatience wouldn't allow me to. The fact is it was a week before it would charge so get your patience slippers on and relax while nature takes its course.
To prevent this from occurring... Always use the HP charger or Touchstone...it puts out a higher voltage then regular chargers. Make sure yours is working.
Try the following in order
1) Hold the POWER, VOLUME + AND HOME buttons down at the same time for 15-20 seconds while being charged (hard reset)
2) Hole the POWER and VOLUME + button while connected to a PC that's on.
If it still refuses to power on:
Let it sit or you can spend a week pushing the buttons with no results. After the weeks penalty box, One I simply placed on the Touchstone and it began to charge. Another I put on the Touchstone and to the USB charger at the same time and it began to charge (removed the USB charger.
Moral to the story, be patient, put the touch pad away for a week while you order the Touchstone charging dock.

S10e won't charge anymore

Hello, I'm running an S10e Exynos with OneUI 2.5 android 10, not rooted with bootloader locked.
Recently, my S10e stopped getting charged, it recognizes the charger (with a little icon) but it doesn't charge at all.
How did this start?
About a month ago, it suddenly stopped getting charged, haven't done anything of interest that may have caused it. although my charging cable's cover plastic was slightly damaged (a bit, near the type-C port) at the time (this may have something to do with the problem?), by now I got a new cable (I did try charging with multiple cables, charging bricks, and outlets, of course).
I rebooted it a few times and the issue got fixed for weeks. until yesterday when it suddenly showed up again and now just rebooting doesn't work.
Can it charge now?
Kind of, it can charge only if I did the following, inspired by this article:
-Connect the phone via USB to my pc (doesn't work with power outlet).
-press volume down + power button while it reboots repeatedly until it starts charging.
Once it got some juice, the device it works fine. Although sometimes even with this it just stops charging randomly.
My questions:
-Is there's some tests I could do to get more info? (since I can get it to boot after getting it charged through the method above)
-Why does it only accept charging when connected to my pc and just with volume down+power button?
-How can I fix this please?
Additional info:
-It wasn't dropped before.
-the moisture sensor still works as intended.
-I'm using the original charging brick and cable (both old and new).
Inspect C port contacts.
Clean the C port carefully. You can use R/O water with a toothbrush, then rinse with anhydrous isopropyl alcohol to chase the water.
Dry completely.
Do Not use high pressure air but low pressure (under 10 psi) is ok. A blower bulb works well.
Use a -known- good cable and brick.
If that doesn't work the C port is damaged or has other internal damage.

OEM Pixel 3 Wont Charge Or Turn On

I went to sleep last night with a Pixel 3 that worked perfectly well and woke up to a Pixel 3 that won't charge or turn on. I've tried two chargers with different USB cables and nothing changed. I'm running stock Android with a locked bootloader. Holding the power button for 20 seconds does nothing and I also get nothing from holding the power button plus volume down.
Did you check it was charging the night before? Try restart the phone when it's plugged in, and see if that enables it; if it does, it probably needs the usb interface replaced. Also wipe out the USB-C port from any dirt or dust. If it's hard to charge or any usb interfacing things don't work, it probably needs the USB-C port replacement. There is also 'wifi charging' but if you don't have access to one already I would say it's a waste of money to get.
Same and for me, doesn't charge and turn on by holding power button. If I'm pluging it to PC there is a sound from Windows of connected device and CODE 10 on device manager for ADB. My PIXEL 3 is from Verzion, and bootlocked...

Question Y700 connected using USB-C to an external display that have PD functionnality

Hi there.
So i tried to connect my Y700 to my Dell U4320Q to see how the PC mode will look like. All i got is a replica of the display on my big screen, and then it kinda turned off.
Now, it won't turn on again... Pressing the Power button for a very long time doesn't make it turn on again. No reaction at all, not even a vibration.
I maybe fried it with the Power Delivery being too strong?
I plugged the original charger, with an USB power meter, and it did charge with a decent speed. So the power section seems to be alive still.
Not sure what happened, but it's scary. Brand new expensive tablet and dead already just by plugging an external display on the USB C port?
Anyone knows how to eventually factory reset it? Or enter recovery mode?
i'm updating my own thread with an own answer.
So as said before, i plugged my Y700 to my Dell U4320Q using USB-C and this has killed the tablet.
Actually, it did not kill it, but it hanged in such a way that it was impossible to reboot it. Even long press on Power button did not help.
So i hoped that it indeed just hanged (it was still responding to adb commands, but since USB debug was not active, i couldn't do anything with it, not even an adb reboot), so i decided to try to deplete the battery by connecting it to another USB-C display that doesn't have battery or power supply (taking power only from the connected device).
This indeed depleted the battery in two days. Then when i tried to turn it on with power button, it did vibrate and show battery empty logo on screen! First sign of life since i connected to my main display.
So i just charged the battery again, and boom, tablet is back to life!
So happy now
