Empty DHD not charging, not powering on, no led.

Hello people
A couple of hours ago, my phone shut down due to empty battery. I came home, plugged it in and booted it, all was fine. At about 60% I shut it off and went to have lunch, when I came back and tried to turn it on, I couldn't.
Led was orange at the time, I unplugged the power cord but the led stayed on! I removed the battery to be able to reboot it, but when I re-inserted it I still wouldn't boot.
Now no matter how I try to charge it, led stays off like it's not charging. Tried various different cables/chargers, the same. Tried to plug it to the charger without battery but no led flashed. Tried to boot without sim/sd card, still the same.
Any ideas?
My battery has never been changed (for a year now) and has had a bunch of full drains. Could this be a dead battery? :/

Well seems the phone is fried... I tried two more official batteries and no go...

Sorry to hear it. I thought that at first when I read your thread but I thought because I am not the most experienced person here, there might be some kind of fix.
HTC will most likely if not certainly replace this handset for you, seeing as it just happened out of the blue.

Well I certainly hope so, problem is I suspect it's an import (from another European country) and local HTC service generally does not do well with European imports.
Anyway I'll give it a try, meanwhile I'm getting a sensation soon

I have a similar problem.
I'm lucky that my girlfriend has the same handset as I do, the I could compare the phone abnormal behavior tho that of her properly working phone.
The first thing I've noticed, after a while when the charger was attached, was that the phone is very hot and that the battery keeps draining out in a surprisingly high rate.
After a while I've noticed that even when the phone is turned off it wont recharge. Sometimes the Orange LED is on when recharging while it is off, and the LED stays on for a few seconds after removing the charger, as if it was still charging. Note that the affects of connecting the charger to the phone, are mainly the ones listed below (not necessarily altogether)
* The phone indicates as if it recharges.
* Going to an infinite loop of rebooting and crashing.
* Getting hot when power supply is plugged, or at any time when the phone is turned on.
Ultimately the battery was empty, and the only way I had to keep using the phone (mostly to diagnose the symptoms listed here) was to swap the battery with the one of my girlfriend's device, and charge my battery in her device while using her's. That's the place to mention that the battery works just fine and that the phone is draining any battery, no matter what.
I took it apart to have a closer look at the source of all of the heat emitted while the phone is turned on, and it seem to come from the motherboard itself.
That's all I have.
The worst thing is that a friend of mine who helped me opening it up broke the pcb of the volume keys. Now I checked and It turns out that that pcb is actually part of the flex cable, which sort of extension of the motherboard and is mainly the second most important piece of hardware of all the phone parts (not that there are so many). If I would be able to expose the conductors inside the flat cable I might be able to solder an alternative volume pad I'll make out of old some miniature switches I have. The cable is very thin. any Ideas of how to expose the relevant conductors without ripping the cable apart?

Just a (late) update:
It's been almost two years, I had given the phone to a close friend of mine after a couple of weeks since writing the first post, just in case he could resurrect it, nothing.
Then, a couple of months down the road, the phone suddenly woke up! He tried to connect it with the charger, after months of not being able to charge or boot it up and somehow it worked. And it has been working flawlessly ever since.
I just got it back to give to my girlfriend until her sensation is fixed, flashing Viper now
In case something like this happens to any of you, don't give up!

Galaxy Nexus sporadically not charging, fast battery drain

My wife and I each purchased a Galaxy Nexus from the Google Play store last July. Recently, my wife's phone started only charging sporadically when connected to a charger. The symptoms don't line up exactly with any other situation I've found described online, so please bear with me while I type out a full report.
I tried removing the battery and using a precision screwdriver to "nudge" the micro USB port "tongue" toward the screen. I thought it had fixed the problem as the phone started charging immediately after I plugged it back in, but when I checked it ~30 minutes later, it had stopped charging.
I tried taking the battery out of my GNex and putting it in my wife's phone; I put my wife's battery in my phone. That seemed to fix the problem, though, again, it was only temporary. I was able to get both batteries to charge to ~80%, then swapped them back. Again, my wife's phone charged the battery, but only for a short while. I swapped batteries twice more to rule out a bad battery; the same symptoms persisted, so I can confirm the battery is not the culprit.
I tried cleaning the micro USB port by removing the battery and using a needle and 91% isopropyl alcohol to clear any dirt or dust from the contacts. I waited for the alcohol to evaporate, reinstalled the battery, and plugged the phone back in to the charger. Same result as before: Phone charged for a little while, but stopped charging before reaching full charge.
We tried 4 different USB chargers: The charger that came with my wife's GNex, the charger that came with my GNex, the charger that came with the Droid RAZR MAXX that I use for work, and the charger that came with my wife's Verizon Jetpack. Same results on all chargers.
Now for some oddities:
The "charge for a while, but stops charging after a while" persists whether the phone is on or off. I turned off my wife's phone at bedtime one night, plugged it into the charger, confirmed that the charging icons appeared (a lightning bolt, then an animated charge meter). When I woke up, the phone was still turned off but only had 13% charge.
Whenever I plug the phone in to my Windows 7 laptop, I'm able to access the file system every time (100% of the 4-5 times I tried). The Battery settings page will say "Not Charging," but I can view and modify files using Windows Explorer without issue.
And now, for a note from my wife:
Unless my memory fails me, I think this was one morning when the charger felt warm on the adapter where it plugs in. Pretty sure this was the day I took the charger with me to work. I had the phone turned off and plugged it in and later turned it on to check the charge and it had been charging. I left it on and it continued to charge. I had to unplug it on three separate occasions and I plugged it back in and it did ultimately charge fully. But when unplugged, the battery did drain quickly, and I had not previously had a battery life issue.

The phone will sometimes get warm--not hot, but warm--around the area under the camera when charging. (I'm guessing it's near where the battery makes contact with the phone.) The charger itself will also get warm sometimes.
Sometimes, even though the Battery section of Settings will say "Not charging," the battery would charge very, very slowly (as in, an increase of 1% charge over the course of 15-45 minutes). When plugged in, the battery would sometimes hold charge (e.g. stays level at ~45%) but not charge or discharge.
When I called Samsung support, I waited less than a minute to talk with a person, explained the situation and symptoms, and was told, yes, the phone is out of warranty (by two months, which I admit is aggravating), but I could send it in for repairs for a total charge of $70.63. That includes shipping both ways. Total repair time would be 5-7 business days. Add 2 days for shipping each way and my wife would be without a phone for 9-11 business days if we were to send it in. It's good to know that the repair are (in my opinion) reasonable because I was hoping to hold on to my phone for at least 2 years before upgrading (and I'd prefer to wait at least 3 years).
I've since got an old iPhone 3GS working on Straight Talk (which was its own ordeal) so my wife has something she can use if and when we send in the phone for repairs. (Side note: My wife really misses Swype.) She plans on backing up her data tonight so I can wipe and reload her GNex and attempt to rule out software and OS as the root cause.
In advance of wiping and reloading my wife's GNex, I had a few questions:
Do you agree with my hunch that the root cause of this issue is hardware, not software? I'd love to be wrong, but all evidence points to a hardware fault.
What ROM do you all recommend for thorough testing in this situation should I encounter the same problems with a clean Android 4.3 stock install?
Are there any other possible fixes you all could recommend before I drop 70 bucks on repairs and my phone has to tolerate the iOS on-screen keyboard for 2 more weeks?

I've had this problem once, I even changed ROMs and it never went away. I changed my charger and it still did the same thing. I don't know what fixed it, but it just started working normally again.
What caused was that I was using it and my device got really hot because I was downloading things, browsing on the internet and playing games on it all while I was charging it. My phone got really hot and a little "CLICK" sounded off and my phone just shut off. It wouldn't turn on until I removed the battery. Cooled it and charged the battery overnight. Although my phone was working now my charger was crazy.

[Q] HTC One X violently died but I think I might've resurrected it?

Please look into this guys;
Last night, I charged my HOX from 18%-28%, used it for a few minutes and then turned it off (it was still at 28%). I then plugged it into the HTC "black box" usb charger (I've been using the same one since I got the phone like six months ago) but turned on charging after 2 hours - and left it charging for like 6½ hours.
EDIT: My brother actually switched on charging two hours after I switched the phone off. [IT WAS TURNED OFF FOR 2 HOURS]
In the morning, the red LED wasn't on, so I disconnected it and tried turning it on - it didn't work.
I tried holding all three buttons for minutes and all of that, but it still didn't work.
I googled the issue and went through a bunch of threads where the exact same thing happened, and most people said the battery either died permanently or something similar. This one person said he fixed his HOX by using a different charger, apparently the chargers themselves can die.
I plugged my HOX into my mom's Samsung charger, and booted it into bootloader, and selected RECOVERY. After a few minutes and to my orgasmic relief, my phone turned on.
I'm still confused as to what happened.
1) Is there something terribly wrong with my phone's battery now? (When it turned on it was at 1%, whereas I turned it off 6½ hours prior at 28%)
2) My HTC black box charger is obviously not to be used now, right?
3) Is there any problem with using a samsung charger on my HOX from now on? Or should I search for another HTC Black Box Charger?
I'll leave it on charge until it reaches around 60-70% and test it out, and let you know if it's fine. But until then, could you please try answering my questions?
THANKS!
On a side note:
I recently had my HOX repaired at the UK service center under warranty. The phone actually had a bunch of issues; yellow spots on the screen, the ruined wifi antennae thing.. Well, they replaced the screen and display, and replaced the Wifi wiring. When I got it back, it turned out that they forgot to remove a plastic cover from the in-call speaker. Thus I cannot use the phone for phone calls outside of extremely quiet places, unless I use earphones with a mic. I let HTC know this, and they said, "Oh, no problem, just send it back to center"
I reside outside of the UK. I had to send it there with my own money and bring it back with my own money. So now I have to choose between spending another $90 or being able to use my phone for phone calls.
Thanks again, whoever bothers to read this and helps me

[Q] Galaxy Nexus charging issues...

A while back, after sweating profusely into my phone during a workout session, my gnex started behaving badly when I wanted to charge it. Needless to say I've got a battery app installed that is able to detect the plugin state (whether the phone is on battery, whether the charger is plugged in or whether it's just a usb connection such as a computer) and actual % voltage the thing has in the status bar. The app itself is: Battery by MacroPinch.
Well I figured the usb port was probably going so I got a new one of those (i.e. flex cable microusb etc.) for my sch-i515. I also decided to get a new battery just in case... so I replaced the battery (it's an oem samsung one) and fwiw, the thing stabilized its behavior! I've since swapped them back and forth with no apparent issues. However, I took my phone out with me on a run and it started acting flakey again. I've (in the past) had to clean out the port with a toothpick, I've had to on occasion bend the flap in there, do battery pulls (which believe it or not worked for a while), and so on. This time however was different. The phone wouldn't wake when I plugged in or unplugged the charger... and in no way shape or form would the charge indicator come on (you know, lightning bolt in the batter icon etc.) and to make matters even worse this time, my laptop simply didn't recognize the phone was plugged in. So I bit the bullet and and did the surgery and replaced the usb board and mic.
It could not have gone more smoothly, unfortunately (as might have guessed) all is not well... so now:
if the screen is dark -
the phone will wake when the charger is plugged in
the phone will wake when the charger gets unplugged
Using a moto droid cable (from my og droid)
the phone/computer realize they are plugged in together and Wug's NRT works and so on.
BUT the battery STILL won't charge.
I guess the phone is a couple of years old and it doesn't really owe me anything (I guess) but I'd really like this thing working better until I can get a new one. Does anybody out there have any ideas on what I might have missed? The phone works as before, exactly fine except it won't chare so I'm pretty sure I managed to get all the connectors back together properly... I suppose the usb port I replaced the original with might be defective but....
Any help is greatly appreciated...
Oh I'm rooted but stock, android 4.2.2

No advice at all??

I WOULD have said bad usb port, MAYBE try another? They are cheap enough, mine has been broken forever and I do not want to take device apart to change it because crack in my screen I'm worried will get worse if I take device apart.
so since its impossible for me to charge battery in device, I'm NOT worried about THAT tho, BECAUSE a LONG while back I had purchased 2 extra OEM batteries, PLUS a OEM samsung EXTERNAL CHARGER/stand which ALSO came with a battery. so I NOW have 4 total batteries, and I charge them up in the external charger, then just swap them out as needed.
which honestly is GREAT, cuz if I'm going out all day, I can just bring my extra fully charged batteries with me, and not have to worry about battery drain from heavy use cuz I have 3 other fully charged ones WITH me.
that's really all I can say, if you would like help finding the exact external charger that comes with a battery as well let me know, I had bought mine on amazon couple YEARS ago for only like 25-30$ BRAND NEW, I'm guessing TODAY that price would be like ten bucks

Thanks... that may be the way to go but I use this thing for my gps... but the thing doesnt get power when plugged in at all it seems (I plug it in, pull the battery and it does not stay on) so far I've been using my wife's gnex to charge my main and spare... but like I said the thing is, the phone doesn't even stay on when plugged in and I pull the battery (hers does so I'm thinking that there may be something deeper in that's failed here). I cracked the thing back open last weekend to make sure all the connectors were engaged, but I did not find any issues with them past that point.
Does anyone know if there is a hidden connecter somewhere in there that i could possibly have accidentally unhooked that prevents input power from reaching the guts of this thing?

OK it's getting crazier all the time...
Since my gnex was "working" except for charging (also, the phone would not stay powered on with the usb plugged in and the battery removed) I decided to go for a long run yesterday... I take the phone with me for music, tracking and general "safety". About half-way through my run, I look at the window in the neoprene armband I'm using and it looks like a sauna... the bluetooth cuts out on me... so I pull the phone out and with a minimum of fiddling I get the music back on... regarding the charging issue ... I was using my wife's gnex to charge my two oem batteries.
Well after this run, I try and use voice to text in a text message after I got home... well guess what... the phone records NOTHING. It's like I'm not talking. So I try a few phone calls... the display shows the call in progress, but I hear nothing! So I use my land-line to call the phone... NOTHING NOTHING NOTHING.
I had previously replaced the usb port, so I took out the tools and disassembled the phone. there was some moisture in there... anyway I dry it out as best I can and reassemble. Now I plug in the headphones, and guess what... I make calls... i.e. the damn phone works as a phone. I pull the jack out and nothing. I turn on speaker mode ... I can hear the phone ringing when I place a call... turn off speaker nothing. Bluetooth works with the phone fine, and the volume control for multimedia makes no sound when I toggle it...
Fast forward to today. I disassemble it again thinking I might have not reconnected one of the straps... I disconnect the volume rocker connector and the usb port connecter plus I remove and re install the antenna housing.
NOW the phone CHARGES but no lightning bolt indicator in the battery... but the battery level is CLEARLY increasing! Also when I plug into a laptop, the usb debugging symbol comes on (since I have it enabled) but when I unplug it does NOT go away... I unplug, disable usb debugging it goes away... reenable usb debugging and the symbol comes back without the phone plugged in until reboot.... but now the phone WORKS again as a phone!
so now the phone:
charges but without any visual indication (other than the % reporting of the battery widget I use)
phone recognized by my laptop (which wasnt' working either until I reset some of the connectors today), but unplugging doesn't make usb debugging indicator in status bar go away.
Phone speaker and mic now working without having to use bluetooth, plug-in headphones or speaker phone. (mic was not working with speakerphone turned)
This is just too messed up. My sweat does carry a lot of salt.... and Im wondering if I managed to shake something loose... I did also pry the usb tab up a bit as well...
Is there some way... some fluid I can dunk the phone into, which might clean the thing without destroying it?

My galaxy nexus after some drops not charging.
It can only work only when i have connected with my laptop, charger.
I think usb port is ok.
I must buy a charging port to make that work?

HELP! Can't charge Galaxy Tab S 10.5

I've been having all kinds of trouble getting my tablet to charge. It's acting really weird. Over the last couple of days, I will turn the tablet on and it will say 80% charged (after being plugged in all night). Then, with it still plugged in, it will drain down to 15% in about 30 minutes. Why would it drain so fast (if at all?) when it's plugged in? It's also been taking hours for it to charge once it hits that 15% and I don't use it.
At first, I discovered my charging cable was to blame. I'd plug it in, but the tablet wouldn't detect it was connected unless I pulled on the wires just right for them to make contact. Apparently there was a broken wire inside the plug of the cable. So I replaced it with a new cable. Everything seemed to be working good then, and was actually getting proper charges again. Now though, it doesn't seem to want to work.
I was using the tablet yesterday to check my email. It had been plugged in all day and not being used. It said it was at 100%. After about 10 minutes though, the tablet shut off saying "battery low". When I try to turn it back on, I get the battery indicator showing it's at 0%. So I left it plugged in the rest of the day and over night. I just went to turn it on about an hour ago, and it's still sitting at 0%!
I thought maybe the cable was bad again, so I found another charger and tried that. It does the same thing the other cable does.. It stays off until I plug in the cable. Then, as soon as it's in, the tablet "wakes up" and displays the battery indicator. Like, it detects a power source has been plugged in. But no matter what I do, and how long I keep it plugged in, it stays at 0%. I can force the tablet to turn on by holding the power button. It goes through the boot animation prior to loading the screen. Then, in about 5 seconds, it turns itself off again.
I don't think the battery is truly at 0%. If it were, how would it be able to boot up without even a cable plugged in? I really don't know what to do now. I've rooted it, so I can't send it in to Samsung for repair. I don't even think the warranty would still be good at this point anyway. The tablet is at least 3 years old (based on when I joined this site looking for root help). And I think it was 2-3 years older than that before I bought it. Is there anything I can do?

I can't wait anymore. So frustrating to own something that's worked great then all of a sudden decide to no want to even power on anymore. I've spent all day trying to get it to charge with other cables. I've tried chargers, I've tried just straight cables. Plugging into the wall, plugging into the computer, plugging into the USB port in the car. Nothing works. So I hopped over to Amazon to just order a new tablet. I can afford it, not big deal there. But then I saw a ribbon cable used to replace the USB port on the tablet. Maybe the port is bad? Lots of "highly recommended" reviews. I went ahead and ordered one. It was less than $7. If it doesn't work, I still have the money to go forward with buying a new tablet. If it does, money saved! I went ahead and bought the "customers also buy" kit, with a replacement battery (just in case it's not the port), and a set of tools. If the cable is all I need, I'll have a spare battery. If the battery is all I need, I'll have a spare ribbon. If it still doesn't work, I'll go back to my original plan.
Just kinda bummed this is where I have to go now. Why would it suddenly just stop altogether like that? Is it because I keep it plugged in 95% of the time? Should I keep it unplugged till it's drained then charge it and unplug it again right away? I used to have to do that with an old cell phone. This is my first tablet so I dunno. If I end up needing to replace the whole thing, it'd be nice to know from experienced users what the best way to do it is, and what, if anything, I can do to prevent it happening again.

I'd suspect the battery is kaput.
It's not a good idea to keep the battery on permanent charge, there's no need. Let it cycle normally.

Well, all told this was an educating experience. I got the battery first. It came about 40% charged. Once it was installed I used TWRP to create a system backup and downloaded it to my computer. Then I left it plugged in overnight. The next day it was down to 30%. So the "charging" indicator on the screen was just a bunch of lies. I got the replacement charging port a day later and installed it. I didn't do anything else with the tablet, just left it turned off and the charging cable plugged in. It said it was charging, but again, after about 12 hours of charging overnight, the following morning it was down to 18%. So I'm returning both the battery and the port. They may still be working fine, and the problem is elsewhere in the tablet. I accidentally broke the little metal connectors over the power button (it's a contact sensor, and the connectors sit on top and complete the circuit when the button is pressed) when I took the back off to replace the parts. I also cracked my screen, although I think it's just the protector I put on it. I'm not sure what else to try at this point. The tablet is essentially a paperweight now. I can turn it on and watch the battery slowly drain to 0%, but I'll never get any more use out of it. So I decided to do a system wipe prior to putting it away for some future project to try and rescue it. Now it's stuck with the "Teamwin" screen flashing at me. I give up. I looked at Amazon to see if I could just buy another one, but they don't have any "new" left. They're all refurbished or "slightly used" from 3rd parties. I looked at other tablets, and bought a new Samsung Galaxy Tab S5E. It looks like it has the best reviews and marks. The only issue would be the wifi, but it seems to be a hit or miss with people. Some people say it's a problem, others say they don't even have a problem. So.. <shrug> I'll see how it works for me.
