So my little sister's tablet the SGT 10.1 just pooped out apparently. About a month ago it stopped responding to USB Mass Storage/MTP when connected to computer and now it just won't charge/turn on. So I tested out the charger/usb on my samsung galaxy note 10.1 and seems that the charger is dead so I was like great, the charger's dead not the tablet. I plug in my galaxy note 10.1's charger and charge the tablet overnight and try to turn it on this morning and it still doesn't turn on (yes I held the power for at least 15,30,60 seconds and also tried to get into recovery or download mode). Is this tablet salvageable or am I going to have to pay a hefty fee to get it repaired? I am out of warranty because this was a refurbished product (never buying refurb again btw). I'm not sure whether the entire MOBO is dead, or the SSD, or the battery. Not sure where to start troubleshooting but am willing to take the time to repair it myself if I have some hopes of preserving her data which has countless pictures and videos. And I'm pretty sure there's no way to take the nand flash chip and transfer the data to the a computer...or is there? Any advice or comments are appreciated. Thank you.
Are you able to get into recovery mode?
Lol did you even read my post? No it doesn't turn on at all no download recovery nothing.

31 dollars to diagnose the problem, 86 to replace the battery, 200ish to replace the MOBO, and 63 to replace the power button. It could be any of these.
Sounds like you have a dead unit to me. I think you need to decide how much that data is worth to you.
Same Problem
Hi Users
i am from germany (sorry for my english).
i have the same problem, the tab normaly works until 12-10-04 in the evening, later i connect to ac adapter, next morning the screen was black, noting works.
I flashed cm9 (http://forum.xda-developers.com/showthread.php?t=1670964) in last week, all was normal for the last week.
Now the tab ist dead.
OK i tested the following
hold power button for 2 minutes, noting
connect to ac adapter, notoing, no icon for loading the battery
hold power button an vol down key, noting
But the led flash light on the back side makes a short flash every 15-20 sec
Help needed
Thanks for answers
IF you are up to it and you know what you are doing.. you could find a dis-assembly guide for the tablet..
Take the battery out and get it checked / charged separately from the unit.. Just make sure you're giving it 2 amps at the correct voltage..
Connect a DC supply at the correct voltage, and limited current, to the unit, and see if it powers on..
That will give you some answers at least as to where the problem lies.
All at your own risk of course..
Try disconnecting the battery and reconnecting it. I know this method sounds too easy but that happened to me. I bought my tab from eBay with a cracked digitizer and LCD, so I didn't know what exactly could be wrong with it. Before I got my replacement parts, it would power up but since it came with no USB/charger, the battery had almost no juice. Before I received the cable, it came to a point where the thing wasn't turning on at all... even with the little juice it supposedly had.. and yes, I was doing all of the button combos. So a few days pass by before I finally disconnect the only component I had yet to disassemble (battery) and I reconnect it and the tab turns on. :what:
I was amazed at why that was even the issue. So that's one thing you could try in your attempt at cornering the problem.

Edit: Does anyone know how to charge the battery externally? I've gotten as far as removing the battery but...not sure what to do now. I found some batteries on ebay so I am able to get a new one, but I want to check to see if this battery is bad or not. How can I do that?
I'm having the exact same issue with my device. It's the same device, and it wasn't refurbished either! I've tried everything I could, it won't turn on long enough for me to reset the device!
I have tried the customer care, but they just asked me to buy a new charger, but I think there's something wrong with the device..

So I had bought this phone off ebay and when I got it today I tried to turn it on, but nothing happened.
I then plugged the phone in and tried powering it on and still nothing. I tried charging the battery and left it alone for an hour and afterwards the result is the same. Basically when I plug in the phone to the charger, the phone's screen will flash a battery icon as if its going to charge for a split second and then go blank. And then it will flash the battery icon again and then go blank again and it will go on like this for a couple of minutes until the screen finally stays blank.
So as I said even though I leave the phone to charge for a while, it still won't turn on and the only result seems to be that the phone gets warm near the camera. Also I tried to see if download mode works and pressed both volume buttons and I get a brief flash of some words. After doing it for several times I saw it said 'Low battery, cannot download' all in red.
I searched the forum and tried leaving the battery out for a while and also putting it in the fridge to see if anything would happen but nothing. So can anyone help? Is it just the battery?
Could be the battery - if you are on good terms with a local ATT store, try going there and asking if you can borrow a battery from their demo device to see if yours will power up. That's the best cheap way I can think of to rule that out.
Other possibility is a bad USB port. My first device developed a failure at about 2 months - I'm actually on day 5 with my warranty replacement. There is another member here, Moustro I think, who also may have a bad USB port. He and I were wondering if perhaps there was a bad batch out there. I'm not sure what ATT's warranty policy is for items re-sold on eBay, but might be worth checking out...
yeah that does sound like it could be the battery boot loop, take some photos of the battery to see if it is the oem... if it is the oem try a stand alone chager

I live in Canada don't think I'd get much help from AT&T probably.
Also the battery is the original one and not a replacement. I left it unplugged for a few hours and just now plugged it back in and its the same battery icon flashing for a couple of minutes and then blank screen. No charging whatsoever. I tried different outlets and different USB ports on my notebook and its all the same.
I also have an Infuse and charging for that every by every method is just fine so its my SII that's messed up.
If it's any condolence to you, I just bought a brand new GS2 from the ATT store today. The battery was semi-charged when I got it, and when it ran out, I plugged it in and got the same thing you did. Battery is flashing, cannot power it on, even plugged in. I also got the red "Low battery, cannot download".
I spent the better part of 4 hours reloading my apps and email addys, and everything else to get my phone up and running, and now this.
I am going back to the ATT store tomorrow and requesting a different brand new one.
This is my 2nd GS2, because I destroyed my first one in an accident.
Just as dandrumheller was saying. I had simimiar issues where the phone battery would blink on and off even if the charger was plugged in or not while the phone was powered off. The only way I could get my phone to boot to prepare it for warranty exchange was to flash a rom through Odin. But if you can't get it into download mode this wouldn't work.
My suggestion would be to use a different battery. That would let you know if its a hardware issue or bad battery.
hmm...
I was able to to get it to power on last night with what little battery was left. I then plugged it into the USB of my Mac, rather than the charging wart. When I awoke this AM, I have a fully charged battery, and a working phone. I will let the battery run out again completely today and see what happens.
That's great news! I hope it continues to work for you
I would not let it completely run out. Our batteries don't like that. Don't go below 25 percent. I'm glad you got it working. I know you're relieved.

Anybody got anymore suggestions?? Can't get it to work no matter what I try.
Call samsung and see if they will honor the warranty? Don't know their rules, but in another thread someone suggested that sale of the phone does not void the warranty.

Were you able to find a fix for your problem? i bought a SGII from ebay and is presenting the same issue
For what its worth I am able to enter download with NO battery. In fact I ONLY do it without a battery. I just hold both volume buttons and plug in the USB to my computer while not pressing anything else. Without battery.
Thought the OP said he couldn't enter download.... so if that doesn't throw it in download it's more than just battery.

Guys,
I tried this and it worked...
At a last resort, i put the battery on nexus to see if it will charge and DAMN !! it did,, so the battery was not the issue...so i grab a swab with little alcohol then clean the terminals on the battery and the spring connectors on the phone... and voila !!! started charging and keeps working perfectly.
It worked for me, hopefully it will work for you guys.
Glad you were able to isolate the problem.

Same problem
Flashing on for a sec then flashing off, buttons flashed too. Phone got hot around the battery. Couldn't have described the problem better
Took some alcohol, cleaned the contacts for the USB connector, cleaned the battery contacts, and booyah, got the charging symbol again! Problem was, I didn't use the phone for a month, it rode around in the front pocket of my laptop bag, and apparently got the contacts dirty. A little toothpick and q-tip fun later, and my phone started charging again. Thanks -

Really? I've had mostly HTC phones and we could run them down pretty low.. I've been running mine down past 10 and it's been fine.. stock battery.
I had the same problem as op. My last resort was to cut the micro usb end of a spare cable and connected it to the (+) and (-) on the phone itself. since the phone booted up, i knew it was the battery. Next, i did the same thing but (+) and (-) on the battery itself while connected to a computer. i held it in place for about 10 seconds. put the battery back in the phone and it started charging again. im sure it wasnt the safeat thing to do, but it worked. Maybe the dead battery needed some kind of jump.
btw. The wires you would be using are the the black and red. and i got this idea from

I believe these are different types of batteries. Not Lithium, but something else. I bought some spare batteries from eBay and the batteries had the same instructions... That it is not good to let them die completely, and charge then preferably when they still have 1/3 charge left.

Hi all. I have a big problem. I placed my phone onto my desk before sleeping (my battery was +/-55%). When I woke up my phone did not want to go on. I tried charging it for 3 hours with my 2 pin charger and it still didn't want to come on (the charging battery animation didn't even show). I also tried charging with the USB cable via PC but that didn't help. I used my multi-meter to check if the battery was working and it showed that it contains +/-3.4V (battery is rated 3.5V). I tried to boot up into recovery mode (volume down + home button + power button) but it still didn't come on
I bought my phone at the beginning of the year (brand new) and it has been working with no problems until today. I have essential data on my phone (phone book, messages, apps etc) which are really important and I wouldn't want to lose them. Help would be much appreciated.

But how can it get bricked out of the blue? Was working perfectly night before happened. The only app I installed was Angry Birds: Star Wars (officially from Play Google Market).
Hard to say. Phones (like any other electronics) can die for all kinds of obscure reasons.
Service centre or JTAG repair; if you choose the latter option (assuming it can be JTAG'd & it's not a hardware issue), you could ask the repairer if they can recover your data. Might be possible. Service centre will wipe it if it if it's not a hardware issue, and if it is, they'll replace the MB which means you get new internal storage/you'll lose your stuff.
LOL.
Its happened to me and its just a BUG...
you may have 100% of battery but the phone is showing like 50%(fake)

Same Issue
I have the exact same issue with my i9100. I woke up and it was dead. No recovery mode, no download mode, nada...nothing comes up on screen. It has been a little buggy ever since the ICS update but it has always worked eventually. I put the battery into my friend's phone and his worked fine. I am really hoping somebody has answers and it is just not "dead". I never used a ROM or anything, it's killing me that a $500 can just die overnight like this. Any help would be greatly appreciated!
If your phone is still under warranty, go to Samsung service center.

I can not believe that just happened overnight, the only possibility is that you put some of the room's, if you have a warranty on the device, you can send it to the service and just hope that they will accept it and serviced
Hello,
So last night I was using my optimus g, the notification that my battery was too low came up, and the phone shut off. After that I went to charge my phone and the usual red light did not come up around the power button and the phone will not charge. There is no water damage or sudden incident that could have caused this to happen. AT&T will not replace the phone due to a small scratch on the front of the screen done a couple months ago. Does anyone have any suggestions about how to get my phone to charge and turn on again??
Any help is greatly appreciated! Thanks!
have you tried to hold the power button down for like 10 seconds? try a different plug outlet and plug it in and see what happens
If you can't get it working then send it in to LG since AT&T won't help you.
Have you tried a different charger? Tried usb charging? Somewhere in this forum are instructions for removing the back case and battery. Two others had similar problems and removing the battery helped.

Yeah, I tried a lot of different chargers, USB charging and different outlets. I will have to try to remove the battery i guess. AT&T told me that I could not have LG repair it because it has a small crack in the bottom left that I made a couple months prior to this happening. Do you know how to get to the thread about removing the battery? I cant seem to find it =/
Anyone have any other ideas?

If that doesn't do the trick then replacing the damaged portion of the phone and then claiming warranty would probably work, especially since it's already bricked and you don't have to worry too hard about it not turning on again after you reassemble it because again, it's already bricked probably a whole lot cheaper than buying a new one off contract.

The only problem is that the crack is on the front class screen, and I have heard that the screen is hard to replace
Before you open it up and go fiddling around on the inside, try these (in order):
1. Hold down your power button for at least 15 seconds.
2. Plug in your charger
3. (If that doesn't work) Use a different outlet/adapter.
4. If all else fails, try the 15 second power button thing and then connect it to your computer.
My Nook Tablet's display wouldn't work once and it took me the better part of a week to figure out that holding the power button down for 10+ seconds manually turns it off (I was a noob). (I then plugged it into my computer instead of the charger and it powered on!) A lot of people forget to try the simple things first...

Ok, let me rephrase that. A new one is $450. You can get a screen/digitizer for ~$85. I'm not a math whiz but to me the difficulty is worth saving that much cash.
download mode
it could be a software problem try going into download mode (holding vol down and power then plugging it in at the same time) it may take a couple trys but if you can get into that then it could possibly be a software issue maybe its a prob with bootloader if it is try useing some teenybins somthing similar happened to me i unlocked the bootloader and everthing got better post back if you can get into download mode

Been doing this charge for like an hour or more, with varius attempts to switch it on but it still it wont switch on! Any tips or anything? I am going to leave it charging for a coupe of hours and see if I have any results...
My phone started having issues where it would randomly shut off and sometimes holding power for approx 20 seconds or so would turn it back on or other button combinations sometimes requiring me to force download mode. I have always been able to force it back on however previously when plugged into a charger the notification light wouldn't do anything.
It shut off yesterday and I have tried every combination of buttons for at least 30 seconds, including trying to force download mode with volume up and down and USB into computer and nothing. The difference this time every time I plug it in the notification light either is solid or pulsing rapidly and will not turn on or go to download mode.
Phone is rooted running paulicats aosp and has been since I got the phone 3 months ago, it was dropped in water the week I got the phone but was disassembled and cleaned that day with no issues until this last week.

Hey guys, it's been awhile since I asked a question, but here I am, lol.
In a nutshell, I'm pretty sure something in my device (hardware) is fried, but I thought I'd see if anyone knows better.
The problem is my device seems to be sending power out of the usb port, and doesn't connect to the pc or recognize it is charging correctly.
This also applies to download mode (windows says device has malfunctioned) and when powered off (there is no battery that shows up when plugged in). In order to power back on after turning it off, I have to remove the battery, then reinsert it while holding down the power. I can't think of much that could have caused this, other than I was visiting places with high humidity levels. One unusual thing that happened before this started was my device rebooted into safe mode when playing bad piggies. That was really weird since I have tried booting into safe mode before, but thought samsung must have disabled it for some reason. I have already tried wiping data and flashing a new kernel/rom. Obviously I can't re-partition since I can't connect to my computer in download mode. What do you guys think? I think it is time for a new device.
EDIT: I should mention that it started behaving normally yesterday for about 5 minutes, but then it went back to this.

I'm 99.9% sure that under normal conditions that an Android device should never power the USB port. Source of speculation. If it is indeed powering the USB, then you've either got a really wonky firmware installed, or some sort of hardware issue. I'd try to make sure that it's sending power out before going further (especially if you can't charge it, the battery will be dead soon). After this test, I'd keep the battery out for a while, just to be sure it's not going to short anything.
One thing I've noticed in my tinkering is that taking a device apart, then putting it back together again can mysteriously fix problems (although 75% of the time the fix is temporary). If you suspect water damage, opening it up and letting it air out might help. I want to say there are certain cleaners that are great for cleaning up any water spots that might be shorting things out, but I've never had to try myself.
That's all I can think of right off. Good luck.

Yeah, I'm working on taking it apart right now. With my limited experience on electronics, I would be willing to bet it's a capacitor that's gone bad somewhere. That wouldn't be a problem on a desktop since I could just solder a new one in, but I don't think I have the skill to do something in such a small scale, not to mention I don't think you can even buy them that small.
The same thing happened to me, and I had to send it in for repair. Luckily, I was still in warranty. Also, are you sure it's not the charger cord?

I've tried multiple cables, and I'm unfortunately out of warranty.
Upon disassembling and cleaning with rubbing alcohol, it seemed to be working properly, with the exception of computer connection. However, I plugged it into a DC car charger (leaving the charger itself unplugged from an outlet), and the light came on again (which is what I was talking about when I said it was sending power out), and now it is acting weird again. I guess I'll take it apart and clean it again...

I guess I'll take it apart and clean it again...

See! Told you taking it apart and putting it back together again works... temporarily. :silly:
You're right, that does sound like power going out. Which would be super cool for powering, say, a micro USB laser pointer, but it's not so great when it should be charging. Can you double check with another device that the charger doesn't light up normally? I know my wife's laptop charger has a LED that stays on for a long time after it's been unplugged from the wall, sipping off of power left in the charger. It could be something similar with your charger.
Just a though... if power is only suppose to go into the device, then wouldn't it be reasonable to assume to that there would be a diode forcing power to only go one way? Or does it need to cycle power back to the charger? IDK, but it might be worth looking to see if something looks missing.
I read somewhere that if the battery voltage gets too low i.e. battery is totally flat, a current will flow from the device to the charger so this may be what's going on here. I didn't really understand the post as I was just whizzing through the thread, but i think the solution was to charge the device for many hours until the battery voltage was high enough for normal charging to occur. I'll try and locate the post, but it might take a while

@iJimaniac if all of these suggestions dont work, there is the possibility to just buy another battery and a battery charger and keep switching out the batteries when they die
Maybe @henk5066 would know something about this?
From what it sounds like, your power circuit is fried and is not directing power correctly this means that you're probably going to have to replace the mainboard. however don't worry. you can get one from a player with a broken screen on ebay for about 10 $. I can p.m. you some links to products on eBay with main board working and not screen and I can post a video on YouTube that shows you how to replace the board. it's actually rather quite easy. I don't get why most people don't do that and instead buy a new one. let me know if that helps

Wow, I didn't realize a broken player is so cheap. I'll look into it, and instructions won't be needed; I've already fully dissasembled my device many times in the past, just for kicks.
Edit: could you send me those links? I'm having a hard time finding very many under $25, which is still a good price I suppose.
the broken player it's self is cheap (0.99$ if your lowest bidder and win) it is shipping that makes up for most of the cost. Just make sure you get one that says powers on, that is the main indicator that the main board is still good.
EDIT: I just looked on ebay, aparantly the person i bought my new board is out of the 4.0 player. and it looks like there is however one with a 9.99$ bid. you could raise it and get the player but that is the cheapest you will get. i will pm you a link to it.
I had the same problem
I had the same problem, what i did was, instead of charging it with the original charger, i charged it with my nexus 10 charger in download mode all through the night, and the next day it would have about 80 percent charge and it was in the system, but it drained quick when i would unplugged it, so i repeat the same procedure over several days until get to 100% and scince then i have had no problems with my SGP, hopefully i helped you

Interesting, i thought the devices could not charge in download mode.
On the subject of odd charging behavieor, has anyone noticed that when plugged in running cyanogenmod overclocked to 1200mhz, the micro usb port area on the player gets rather hot?

Oh sorry. APX i mean. my question above is now edited. Any idea sir? or i should brought it to samsung service center?
Maybe the only thing to try at the moment would be the old battery drain technique... Usual means is to tape down the power button and wait days and days until it is dead, really dead ( shows nothing when connected to computer), then connect to wall charger and reboot and see what you get. This is really the ultimate "hard reset" but same result can be obtained far more quickly by removing the back and disconnecting the battery for a while to remove residual charge... Not as frightening or difficult as it might seem, have done it loads of times for various faults and to replace batteries in several tabs.

thank you sir. Im doing it now. But Im a doing it correctly? i just connected it to the computer for apx mode then after that i tape the power button so that it continuously on and off for apx mode then i disconnected it to the computer or I should leave it stay? i think it will charge if i connected it to the computer.
If you're trying to discharge by taping down power button just leave the tab on it's own not plugged into anything... Plugging into something that charges rather defeats the object of the exercise

Samsung Service Center
Thank you for the help. I think I need to bring it to service center. There's no battery charging icon when I charged it. I dont know if its well drain but I use a laptop cooling fan via OTG to drain it. the fan and the lights from the cooling pad is not functioning anymore so i try to plug the tab to the wall charger and nothing happens.
By the way thank you. :good:
Any luck?

In some cases it takes more than a day, be patient... Unless you are prepared to remove the back and unplug battery... The aim of the game is to completely power down the tab and remove residual charge in components, the "hardest" reset available.... So, two ways to achieve that is drain battery or disconnect battery... If you drain battery you must be sure it's empty to achieve desired effect then you obviously cannot restart it without charging a bit as the battery is empty, so you connect charger then try to boot, but the tricky bit is being sure the battery is completely drained otherwise you are just wasting your time... That is why battery disconnect is preferable

How do you disconnect the battery to discharge. I tried the taped power button for five days and it still seen by PC in Device Manager.

Suggest you go here http://forum.xda-developers.com/showthread.php?t=2325109 download the manual - then unplug the battery for 10 mins or so to remove any residual power, reconnect and see what happens
Good luck
Edit....I got beat to the post. I would follow the advice above first.

Look for some videos on YouTube because it involves removing the back of your tab. So see seeing it done is a great help.

Many Thanks to You stinky73
I had to purchase an iFixIt repair kit to get the correct driver to remove the two screws. I disconnected the battery, waited ten minutes and when I reconnected I was SO HAPPY to see the battery charging icon. I charged for a while a fired up the tablet. Everything was the same as if nothing happened. I am so happy because Samsung said they could fix the problem and it would be a flat rate of $150 which I don't have and I would lose everything.
Many thanks

How hard was removing the back? I'm wanting to do some building for my 7510 and will be using it for testing so I'm most likely to brick it at least once or twice.

It took me longer to remove the screws then anything. I stripped them and will need to replace them. I tried a regular screwdriver before the tri-wing screw driver and paid dearly in time. Once the two screws were removed, use a plastic pry tool starting on the bottom where the screws are because once the bottom and sides are pried lose, the top will slide over the extended audio jack.
1.5 hours to remove stripped screws
10 minutes to pry open
1 minute to disconnect battery (did not remove battery or three data cables on top of battery)
10 minutes wait for discharge
3 minutes to re-connect battery cable (it slides forward and snap down)
2 minutes to replace case

Forgive the gravedigging, but I am unable to find anything regarding my situation, and the original poster has a problem that is similar to mine (my thread is http://forum.xda-developers.com/showthread.php?p=52931715 ). I hope someone is able to give me a hand here!
I am wondering, it has been over 15 minutes since I disconnected the battery completely, but connecting the P7500 to my laptop still shows an APX device being connected. Could there be some hardware issue preventing the device from being fully discharged?
Thanks in advance for any help!

I've got the same issue as Lightside and the original poster. Mine is a GT-P7500, which had CM10 nightly ROM with CWM recovery. I sold it on eBay, but before selling, I wiped the tablet and got it back to the Clockworkmod main screen. I turned it off completely and shipped it to the buyer, ready for it to be registered by the new user.
The buyer received the tablet and from the e-mails I received from him in the first couple of days, all was going well. Then, a couple of days later, he sent me an e-mail saying that the screen shows the android lying on its back with "Odin download" mode showing. A day later, he sends me a messaging saying that he can't turn the tablet on at all. The guy who bought it is an old man and didn't know much about fixing the issue. I asked him whether he powered the tablet off while still plugged in to the wall charger and he confirmed that he did. I asked him to return it to me and I can try and fix it, so now, I have the tablet back and it won't turn on. Here's what is happening:
1. I drained the battery using the cellotape method
2. Installed the NVflash drivers
3. Waited for the battery to drain (almost 9 days and the LED flash stopped blinking, so assumed it was completely drained)
4. Plugged it in to the PC and it immediately showed up again as a device under the USB controllers within Device Manager
5. I then unplugged the battery by opening the back of the tab, left it for 15 mins, then tried the wall charger again, but nothing. No charging icon on the screen.
When I try to press the power button, I can see the LED light up, but the screen is still blank.
Could this be a hardware issue and if so, what do you think could have caused it?
Could really do with some help here, folks! I don't want to have to give the buyer a refund because technically, he got it when it was in working condition and he probably did something to screw it up, but since he's an old man, I thought I'd try and help him, if I can.
