Weird battery issue - Transformer TF300T Q&A, Help & Troubleshooting

Hey guys,
About a week ago I replaced my working tf300t with a nexus 7 (2013) and I was thinking of doing some sort of project with the tf300t so i took it apart and looked at every part (ofcourse i turned the service switch off to skip damaging the touch screen controller) when i reassembled everything and I plugged it in I got 2 blinking red lights! and it would not turn on! I then decided to open it up again and see if i switched the service switch back to on, which was on! I decided to run some tests, I unplugged the battery and plugged the tablet into the charger... and guess what it turned on! I unplugged the charger to look for other stuff and because I was so stressed I forgot to flip the damn service switch (this broke the touch screen controller :/)
My main issue/question now is; what is wrong with the battery? I don't need the touch screen for my project but i'm still wondering why the battery refuses to chrage! I checked the cables a billion times and I cannot manage to push the battery connector in even more so I guess it's correctly seated. Does anyone know what's wrong?

Help Please! XV6800 not working

I have an XV6800, all of a sudden it will only work if I have it plugged into a charger...and yes, the battery IS fully charged. The second I unplug the charger, it goes to sleep and won't wake up unless I plug it back in. The last thing I was doing when this started to happen was trying to get TouchFlo and Action Screen to work, neither would by the way. I removed both of the programs and restarted, several times, but nothing. Can anyone help please?
Full disclosure: I am a designer and use Mac primarily so I don't know a lot about Windows.
Thank you for any help!
if you ask me it sounds like the batt is defect
I've been using it non stop for a week and half though with no problems. Could it still be the battery? I forgot to mention that I had also plugged it into my Mac for the first time with the USB charging cable before it went buggy too. But it works if it is plugged into that.
any electrical component can kneel over and die any moment with or without an warrning
you can try to take out the batt and see if it still act the same when connected to the power source
Figured it out...somehow the backlight setting for battery power got turned to off, so it wasn't really shut off, just not lit! Sorry! Thanks for your replies.

[Q] Triumph suddenly dead!

A few hours ago my girlfriend was just looking at her Triumph (was watching for messages so she wasn't actually doing anything on it) when the screen turned off. Now it wont turn back on. Have tried the power button, turning on the bootloader, and removing the battery for 5 minutes. No matter what we can't get the phone to turn back on. Any ideas on what has just happened? The phone is rooted with gingerbreak with titanium backup installed. That's it. We got the phone at Best Buy and this is our second phone. We're probably past our 30 days so this kind of bugs me! Any idea what we can do from here? Any other tricks to try?
As a quick update, Best Buy tells me that an Exchange counts as an original transaction. So I'm only 17 days into my "new" transaction. I can't believe neither of these Triumphs have lasted more than three weeks :\
Did you have it connected to the charger while using it? I have noticed it gets very hot even without the charger being plugged in. It may have over heated. Just a thought. Good luck. Let us know what happens.

No, the charger wasn't connected at the time. It was just sitting there with the screen on. The Significant Other wonder why it wouldn't turn off so she hit the power button and it didn't do anything. Finally the screen just went black but the backlight was still obviously on so she pulled the battery and put it back in. From there, she pushed the power button and the virgin mobile logo came on and nothing else. She had to remove the battery again. She put the battery back in once more and was able to get the Virgin mobile logo one more time. It froze after the logo and she pulled the battery one more time. After that the phone refused to turn on at all. When connected to the charger it doesn't do anything. Still completely lights out on the phone.
Man that sucks. I hope your able to find a fix.

Same thing happened to me the other day. I let my Triumph lose all its battery to charge it back up 100% (performing a full battery charge cycle), and it will no longer turn on. even when I have it plugged in the red light indicator will not light up most of the time.
Funny thing is, this is also my second exchange from best buy and luckily im still within 30 days and i have a replacement plan. I really suggest getting the replacement plan (its $30, good for a $300 phone), because unlike best buys other mobile protection plans, you dont pay monthly, you're covered for 2 years, and if you get tired of getting the same phone, they will give you a $300 store credit card.
You know my phone did something similar, my phone died and when i went to plug up the charger i got nothing. I think there might be something wrong with the charging ports on these phones, try wiggling the charger while its plugged in, thats what i did and it finally took a charge

upon closer inspection of the charging port, i noticed the female micro usb port was actually pushed further inside, thus preventing most chargers to work. I found a rocketfish charging adapter from best buy that seems to work perfect while my other cable didnt work at all.
As an update, we went back to best buy and sure enough they count the exchange as a new transaction, so I was only 17 days into my second transaction. They exchanged me another phone on the spot and so now we're on the third triumph. GPS checked out ok and the MEID was the correct length. The screen is the worst of the 3 (some pretty bad backlight bleed out onto the screen itself from the sides). I was picky about it but the gf isn't since you can't even see it unless the screen is completely black. So we'll see how this one holds out!
My guess is as was assumed, the battery wasn't getting charged. When the battery was removed for 30 minutes or more we were able to get the logo to show up and nothing more. My guess was the charger wasn't making contact anymore. We wouldn't want to keep a phone like that anyways but it seems like this might be a problem for these phones.
Every once in awhile mine will not power back on. It happened to me a couple of times shortly after I bought the phone.
I tried pulling the battery a couple of times and powering back up, no go.
What worked... remove battery, press power button for a couple of secs, replace battery, power back up. Has worked every time... so far.
My guess is need to drain some capacitors or that I had invoked part of boot recovery sequence without finishing?

Have you noticed the "I just broke my Triumph's Screen"- post? We'll If you saw my cracked Triumph, well that's another issue that I just discovered. The battery drained all the way and now it will not take a charge anymore. This is the exact same problem OP is having. Regarding this issue I will open up my phone sooner or later when I get a new one and take pics. I don't mind seeing wth is in there, maybe everything's held up by Elmer's glue lol. I'll make sure to let everyone know hopefully I'll do this within a couple days.
It seems like dead
If Motorola and VMUSA are not serious about resolving issues for Triumph then this phone will be dead anyways - customers won't be buying those. The number of returns are far more than new purchase. It seems like Motorola stopped manufacturing these.
So this phone will either get Ice Cream Sandwich update or it is end of life for this phone.

Inspire is DEAD. grrr.. Help?

So my phone battery was dieing. In fact the phone powered itself off. So I went to plug it into my car charger, but the charger port (on the car adapter) was damaged so i never plugged it in. Instead I grabbed a usb charger out of the glove box that I had bought on ebay and never used before. I plugged it in, saw the big battery icon and a few seconds later the phone booted up and I saw the HTC logo. I left the truck and went back to work. When I got doe about an hour later I discovered the charge light on the phone was no longer lit and the phone would not respond to pushing the power button. At this point I figured I killed the battery and would need to try to charge it manually when I got home.
Upon getting home I put the battery in my wifes inspire. It curiously charged it up no problem. So I put the charged battery back in my phone and nothing. It wont do anything. I tried her battery, nothing. No lights, no vibe no nothing. Like the battery is completely dead... But its not.
I actually just bought this phone used about 2 weeks ago its been workign great until now. Im really bummed. I had 2 atrix's get the boot loop problem and another phones screen went. All in the last 3 months.. so annoying.
Im figuring that the usb charger might have an over-volted output and somethign got fried? I have no idea but if anyone can help me that would be great.. I've spent almost 400 in phones in the last 4 months
Thanks!

Also all covers must be on (sim) (battery) to turn on. Sorry dont know what to tell you, phone may have bit the dust. When you left it in the truck charging was it a hot sunny day. You may have damaged internal hardware. If you purchased phone on ebay open a claim against seller. I had a phone I purchased for 400 that kept frying the battery. Ebay made seller refund money back.
See if you can hboot power up holding power button and volume down button at same time.

Device Just Stopped Working

Hey guys. So a month ago I was using my device like normal and noticed it was getting a little low on battery. I put it up for the night and started to charge it. The next morning I pulled if off the charge and noticed that the unit did not want to turn on. I figured that I had it plugged into my phone charger and since the TF700 is a pain and only likes certain charges I checked and plugged it into the OEM charger and left the unit there to charge while I went into work.
I got home that day and realized that the tablet was not charging at all. I figured that the sync/charge port got messed up, since I have 3 LARGE dogs that constantly hit things off the table, so I did what any XDA member would do, pulled up iFixit, and tore apart the unit to get the part number on the cable.
A week later I get the part in and swap everything out and guess what, still nothing. I had the unit plugged in over night and nothing at all. No LED lights turn on or anything.
Finally, I decided to pull my brothers TF700 apart to check the cable and both the ones I have work....soooo ???
What else can I do? I might just part everything out but really just want to get the unit working again.
Thanks in advance.

Changed battery on dead Nexus5, still doesn't work

Old: Phone was working fine at around 7% earlier today when I plugged it in to charging (worked at this time) and went-on playing Civ5 for about 40 minutes. When I grabbed it after that that screen was black and the phone was non-responsive. No charge icon when I plug it in and vol up+down + power doesn't work, nothing works , any help would be appreciated. Note that I dropped my phone into clean toilet water about 2-3 weeks ago but after vaccuming it and leaving it dry for 30 hours it worked just fine. I don't if this (battery dying?) is related to it.​
I changed the battery today to a brand new and the phone still doesn't turn off. What could have possibly ****ed up inside the phone? I though maybe charging port but the phone doesn't even turn on for a bit or show any signs of survival. It doesn't even show up when I plug it in to my PC/Mac... Should I spend 10USD buying a wireless charger to test if it has to do with the charging mechanism or should I just ditch this phone...?
I have this same problem, except on some chargers it gets really hot. Otherwise same as you
I am having a similar problem. One day it shut off and it would only boot to google then go black. LG said it was an LCD connector problem and said it would be $150 to fix...i opted not to pay $150 and when i got it back it was on a previous android version 5.0 i think and it worked fine for a few days. Then i did the update that came along and it sropped working again.. wont connect to computer or turn on. Any chance it is software related? I have a new lcd on the way so i will let you know if that fixes it..
Hello, did a new LCD fix it?

Could be a charging port issue? I have a Samsung s4 that was dropped in water. When it dried, it booted but I got a weird message that said the battery temperture was too low and charging was paused. I changed the USB charging port and the phone now works perfectly without changing any other components.
