[Q] Charging Problem - Nvidia Tegra Note 7

Hi,
By battery was running low so i turned the tablet off, plugged it in and went out. When i came back i turned it on only to find that the charge was at the same level as when i left it. I first thought it was the charger, but after testing it was fine. On plugging the charger back in the battery symbol comes up and shows that it is full, before the screen goes black for a short period before the symbol comes back up again showing it is full (Im unsure if it normally does when charged as i cant remember)
I then turned the tablet back on and left it to charge. The device charged slowly, but when i checked the battery status the tablet claimed that it was NOT charging.
Im worried that when it runs down it will not charge to turn back on. On the other hand it might recognise the battery is flat and charge normally.....
Anyone got any suggestions?

Update: I left it on and plugged in overnight and it charged back up to 100%, albeit very slowly (I woke up once and checked and it had only reached 75% after about 4 hours).
So still not sure what to do. Factory reset?

Even i had the same problem
Try changing ur usb cable,
it worked for me

Stock USB cable lasted one day for me. Absolute garbage. No problems using the stock cable from my ancient HP Touchpad.

Sorry to jump on a fairly of thread, but....
Hi Barking Mad,
Did you ever get to the bottom of your particular charging issue? I've bought a TN7from ebay, and I'm having ng exactly the same problems as you described. Not really charging when turned off and the screen showing the charging symbol for a couple of seconds before going black and then showing the same symbol again. It will charge whilst turned on, albeit it very slowly.
I was just hoping you may be able to shed some light on my problem for me!
Thanks
David

make sure you use a hi capacity charger 1A plus most phone chargers are too low and will only trickle charge when the unit is off, also my four came from ebay with no power faults and I patched a QI charger inside the casing as the usb ports had failed.
I'd do that to any tn7 now as the port is just too fragile and might be needed for an emergency recovery.

Wizard won´t recharge!

Hi,
My wizard run out of battery completly yesterday, I brought it home and try to recharge it, but no recharging light will appear.
I left it overnight connected to the mains but to no appeal,
I also removed the battery for a few minutes and then plug again but no luck.
I´m not using the mains provided adaptor but my travelling kit, a proporta mains/usb adaptor and a retractable sync/charge cable with a mini-usb pin cos I´m back home for Xmas and I don´t travel with the mains.
I have read about problems with some chargers from Boxwave, but I have consistently using this charging conbination since October.
Any ideas, should I send it back to expansys to repair, or is there anything else I can try?
Thanks
Elsral
same thing happened to me.. Supposely the phone will not charge from being completely dead without a charger that puts out 1amp. There is another method if you are a little brave... cut up an old car charger and hook it directly to the battery (red cord to + on battery and black to -) Read about it on howardforums and it worked like a champ. I only needed to jump the battery for about 30 seconds before I put it back in the phone and the amber light kicked on.. I was very relieved!!
Same happend to me yesterday. Simply plug the carger in and wait 1 or 2 seconds then switch the power button. After some seconds the carging light should switch on.
The wizard won't charge if it's switched off.
Export800,
you are a megastar,
I put apart a usb adaptor that I had built to charge my gps and I connected cables directly to battery for a minute and Voile,
tnx a million,

But if the battery is totally dead surely the unit wont switch on ? Thus its a catch 22 ??? There is no power to switch on and the battery wont charge totally dead.
Ridiculous if you were caught out away from a charger and ended up having to pull apart a usb lead to get things back to life.
If the battery is so low, that the wizard switches off itself, and you connect the charger, it won't charge, because it's switched off.
Use the power of the charger to turn it on, then charging will beginn (and also the device will boot).

Can anyone else confirm this works as there have been many people having this problem. Simple solution if it works.
Switch off your device completely (hold the Power Button) and try to charge: Nothing happens. Now switch it on - charging begins.
I have noticed that last week, when battery was very low and i know that i would need my wizard in about half an hour. So i switched it off completely, so that it would charge faster and noticed that.
Yesterday when battery was totally dead i remembered that and i switched it on.
Btw, doesn't it damage the battery, if you connect it to 12 V (!!)??

If I come across the problem will certainly be trying your method before I will be ripping into any usb leads
The same thing happened to me this past weekend. We were out camping and my MDA's (wizard) battery went completely dead. I had a USB sync cable for my laptop, but that would not revive the unit. I'm afraid the only way to bring it back to life is with the original OEM charger which has an output of 1 amp. Thanks for the post!
I had the same issue a while back. At first I thought the moto charger I had was dead but then I plugged in a old SMT5600 and it worked fine.
I left it plugged into my computer for a hour or so and finally I heard the "new usb device blip" from the other room and it started to charge. Guess I was lucky.
Same thing happened with my wifes SMT5600. The battery died and she couldn't get it to charge with her moto mini usb charger. I plugged it into my machine and a hour later the charging light came on.
I have heard that the Wizard will not charge from my laptop using a usb cable if it is completely drain. I find this to be NOT TRUE.
I ran out of juice twice last weekend. The thing about the Wizard is that, if it's completely drained, it will get stuck at the boot screen, and go no further.
Take out the battery to turn it off again. Put the battery back in, and then plug in your charger. DO NOT TURN IT BACK ON. It needs all the power it can get. Give it a minute, and you will see your orange charge light come on. Just leave it alone for several hours, and it will charge. This is my experience.
I got it! But, first the story.
None of the above methods helped me. I tried plugging it in to a big truck lighter, a pickup truck, even an ac adapter for my coleman cooler. Nothing!
However, I had a powered Pro-Clip mount that I had as a backup for the one I use. Guess what? THAT worked!
I think the cable makes the difference. Need to find the specs on those puppies. LOL
Thanks for the help.

Question about charging the phone

Hi there! I just bought a Cingular 8525 Unlocked phone and absolutely love it! After having it for two weeks, so far i have upgraded to the 2600mah extended battery and i am currently using PDACorner v20 rom (nonRBSN)
Now to my question, is it bad for the phone i keep plugging it in randomly throughout the day on the charger or USB? I upload files sometimes and i just leave the phone plugged in the computer or I would sometimes charge the phone when it hits 70% and unplug when done and would charge again before going to bed.
Also, is it ok if i leave the phone on the charger even if the light turns green? sometimes charging would be done around times when im knocked out....and usually dont unplug it until i have to leave.
Thanks for your help/replies.

Well, I don't think that's such an easy question to answer. There have been the following reports:
1
Attempting to charge the battery with either PC USB or non approved charger (500mA) if the phone has less than 10% charge can lock up the charging circuit and result in a Red no charge LED showing.
2
Leaving the phone on charge overnight for example can result in the curious situation of having a flat battery and RED LED showing in the morning.
3
In general problems can result if 500mA 5v chargers are used instead of the 1000mA official charger - particularly if they are used when phone charge is low.
Now despite all the above, I regularly charge overnight without problems - and clearly that means the green LED is on for most of the night. I frequently top up the phone with the PC USB and do sometimes use a non standard charger. I have only ever had the RLOD red light of death once and was able to kick start it eventually.
I generally do not let the phone fall below 20% - but even when it does I have had no problems.
Mike
Thanks for the reply. I never let the phone fall below 40% so i should be ok on that. But when i bought the extended battery it came with a wall charger but its 500mA.....im guessing its ok for the battery since it was packaged with it.
But i might look into buying a charger from ATT. Leaving it charged till i wake up should be ok then....thanks!

Anyone having charging issues?

A friend of mine just picked up a Droid X today and he's having problems.
First, the charger it came with doesn't appear to charge, there is no charging indicator light.
I attempted to use a number of USB chargers, the first from my HTC Hero, another from an iPad, and a third is a cheap Chinese AC charger with a USB port that I picked up for my EVO.
The only charger that turns on the green light on the top is the cheap Chinese one.
If I plug it into my computer, I can also get the green light to come on, but it doesn't appear to be charging it. When the phone is on using the cheap charger, the phone appears to work, but says on the lock screen to plug the phone in.
Further, the lock screen is not responsive. We let it charge with the phone off for about a half hour with the green light on, the phone boot up and had a little bit of life and the screen did work, then it suddenly turned off and won't boot past the Motorola logo (just flashes for a couple of seconds then disappears.)
So, whats the verdict? Hardware problem or is anyone else experiencing this? The phone did completely die, so I wonder if that caused a problem of some kind.
Do you have a Green light when charging with the phone off? Does the light flash red when it's on and charging?
Thanks for the help!
I plugged it into my home computer and nothing happened vs. being able to charge my computer and nothing. Although the phone was about half way charged before I plugged at work, vs 10-15% at home.
Mine didn't charge while plugged into my netbook, but does charge while plugged into my PC, and definitely charges while plugged into the wall charger.
Update: After using the wall charger and fully charging it, I connected the Droid X to my computer and it now syncs up. Maybe the amount of battery power matters?
I don't think the green blinking LED is a charging indicator. Mine charges without it....but I notice when I was charging it the first time, it was going off when I had an unread text message. Is everyone sure the green LED is supposed to be a charging indicator? Mine's charging right now according to the bar on top when I turn it on while it's plugged into my computer.
I'm having a charging issue with my car charger.
When I plug it in to the car the audio volume drops to almost inaudible and the voice commands don't respond anymore.
This is with all the volume sliders set all the way up.
I have to reboot the phone in order to get it to work again.
I've charged it connected to my PC at home and work and it works fine with those.
Wow, the OP totally describe my problem i had too. I went back to Verizon and got another battery. My first battery wouldn't charge above 50% and the second came with 80% and we tried charging it at the store and it never went higher than 80%.I read on another forum that the charging indicator only reads at every 10% intervals, so that may be the problem. The rep and I at Verizon was watching it to see if it would move up to 81% so we would know it was working(beside the bubbles moving animation) and it didn't and we gave up, I will see what happens when I charge it tonite with the AC plug for the first time.
So the green LED light is not a charging indicator. Apparently, there is no charging indicator at all.
We left the phone off and plugged in with the stock charger, no light, but it did gradually move up.
I did some searching on the Motorola forums and another user ran into the same issue, he said that leaving the phone off and charging it for an extended period of time solved the problem.
I have no idea what the green light meant when it was plugged into my cheap Chinese charger, it must have been nothing.
It wasn't a text message or any other kind of notification since it was on only when the phone was completely off.
Before he left with the phone it was up to 90%. A brief press of the power button brought the phones battery state up, but didn't boot the phone.
Hope this helps anyone else with issues. Just plug it in and let it sit overnight.
I had a similar issue the first day.after overnight charge all seems normal for day two.

The only charging indicator is the lock screen part if you just turn it on it will tell you at what point it is charged.

It will occasionally show 5% intervals when it gets below 20% (I've seen 20, 15, 10, and 5% intervals).
I've noticed my phone doesn't like charging from a computer while the battery is really low. Once it's had a little bit of a boost from the wall charger, it will charge fine off the computer.
I just changed to a new one today.a friend of mine is having the sand issues. As so did i. It seems its not the battery its a short on the ground on some phones. Its pretty awkward but it has only been a handful from a batch of thousands that were released. So were in good money.

Is this good or bad?

When you said charge fast you're referring to wall charge? Car charge? Or usb charge?
Stock X
Hey guys,
Figured I'd swing over here and give this a bump for a buddy of mine. Seein if this may be a slightly common issue.
The situation(for him): All on stock phone NO ROOT
- No charge on wall/home charger. Shows charge indication but does not actually charge whatsoever.
- No charge using PC usb cord to charge.
Again everything is stock and not currently running any app killers or really anything out of the ordinary as I can tell. The only thing he has purchased and is running that I am aware of is Launcher Pro. The issue has been brought to the attention of Verizon which is his carrier and he just received his 4th phone! Honestly thats the only reason I'm posting an inquiry into this hear. A simple google search results shows others with similar issues(posted link at bottom). He has purchased a new battery and wall/home charger along with another USB cord. All 3 phones he has had produced the same issue with all of the charge accessories(4th phone just received so no tests as of yet, but i put money on it doing the same thing). Verizon has been willing to replace every phone so thats not a problem but seriously! Is that the only answer?
any help is appreciated in advance

There are two charging indicators, no lights! One is on the status bar, you'll see a lightning bolt through the battery meter, and on the lock screen it will say charging as well with a %.
Absolutely, yes sir. Both indicators(lightning bolt in battery, and battery charge indicators) light up and show charging. Although once phone is unplugged it will keep whatever the charge level indicates for a random amount of time usually between 1min-15mins then the battery indicator drops immediately and shows an almost dead battery. As in charge shows 80%, unplug and within mins phone shows 10%.
Also:
- There are no other indicators of charging other than those mentioned (as it should be).
- The phone connects to PC just fine for mass storage. Files transfer with no problems.
thanx again!
So... which one is it? First you say no indicators, and now there's indicators but it just doesn't hold charge. is VZW replacing the phone or the battery? sounds like a bad battery to me.
My apologies you are correct *edited post* i meant to say it does show charging as in you see the lightning bolt and everything even the battery icon fills to show a "fuller" battery although that stat drops almost immediately after unplugging.
As in replacements they replace the phone and battery as well. I know its the 3rd phone so far with the same problem.

[Q] Help! Battery won't charge

Need some feedback, any one has had a bad battery yet? I had mine charging up to 85% yesterday and went back to bed thinking that today (sunday) morning will wake up and do some early stuff but I woke up late and had a dead Streak next to me. I left it charging overnight (I know it was only 15%) but you never know when you're going to need that extra juice. I tried turning it on, no luck, took the batt out tried turning on with only the mains plugged in, no go, I had blinking LEDS for a short moment then it turned off and that was it until I decided to jump start the phone (I don't recommend doing this to no one) with a BB Bold Battery (3.7V 1500mAh) all of a sudden I get the battery with exclamation mark, like I had a dead battery, I've only had the device for 2 weeks, also this is a Beta Unit I bought "AS-IS" but the problem was a simple restore and not the battery. now I manage to charge the battery in a raw way, just hot wired into a 4.2v DC. now the big question...
I'm at 40% battery it is draining very little, I would even say it is under normal operation, but i can't tell I don't have a SIM on it ATM. but I checked on "spare parts" to see status of the battery and it all seems ok but the bit that says BATTERY STATUS: discharging
No matter where I plugged the wire it is discharging, the phone is being detected on windows/mac any computer I plug, the phone does detect where the source is coming it says AC when I plug into the charger that came with, if I plug it into the USB of the computer it does says USB but it will never say charging, I even transfered files to the phone to test the wire, seems to me I have a crappy battery but just need more feedback, anyone has had this problem before? on any phone should I call Michael Dell and order another batt?
P.S. I have a BB Javelin had the same problem did jump started the battery and now the mobile is charging no probs and it DOES hold charge.
UPDATE: Ok guys any of you running 2.1 (8105) on your USA Beta (probably regular too) and have this issue about not charging, I went back to 1.6 (4399) issue is gone, I also had the crazy screen couldn't unlock/answer phone, will see if that is gone too, more than likely it is but I'm not 100% sure.
if it wont charge using usb or mains but only by jump starting it, then the streaks charging circuit is most probably f***ed.

Problems with phone

Has anyone heard of these problems before? The first one is that the back and menu buttons don't work. They don't even light up when its turned on. Second problems is the battery doesn't charge well, I will put it on charge when its turned off and it won't get to the charging animation and for example when its on and shows its charging I pull out the cable and its still showing as charging. Also the percentage of battery left was all over the place sometimes. I turned the phone off, when I turned it back on about (without the charging cable in) it went to the charging screen, so turned off again and on again, this time it started up fine but when got to the home screen its still showing as charging with no cable attached. When I got the phone the battery was completely flat, so he must have had some trouble charging it too (he supplied me with a black 1a charger rather than the white 2a charger they normally come with)
I got this phone off eBay so I am sending it back, it had a new screen put on it apparently they didn't wire up the back and menu button? as for what's causing the charging problem? I noticed there were interference type lines when I used the touchscreen when it was charging. I was able to charge the battery in this phone in my other working S4. There was a OTA rom update but that didn't fix any of the problems, I'm guessing they are hardware problems and not much I can do about them other than send it back?
