Hi, I start this new thread as a new user and my first message because I'm really really worried about my samsung galaxy 10.1 tablet, It is a wi-fi only tab I bought through Amazon, and has just arrived to my country, Costa Rica, so, as any normal person, I opened the box, readed the manual and turned it on, and started checking everything in the tab, and when finished, (because I don't have wi-fi yet) I turned it off, and started to charge it with the factory charger (AC conector) it has been 5 hours since then... It has not turned on again, no matter if I press the On button 30 seconds, nor turning it on conected to a computer, or to the AC, or without anything, so I called support, and they said the same thing I was expecting, charge it and see what happens, and nothing happened, I'm really really worried about my tab, 600$+shipping is a BIG amount of money to have invested, the computer is brand new, as you will buy it from the second link availabe in amazon when you type samsung galaxy tab 10.1.
Can you help me?
Tab does not turn on..
What finally happen did it turn on...If not there is a why to reboot it by holding the vol. button and the Power.
Hope it went well, don't give up..
That is why I made this thread, I already tried the volume technique, with +, with -, with both, with + and shaking, with - and shaking, and all those with also touching the screen, an nothing!!
when you turned it off and plugged it in to charge, did you notice anything appear on the screen indicating that it was charging? Normally when turned off and plugged in a battery will appear on the screen. even if the screen turns off you can touch the power button to show the battery again.
If no battery ever appears, then it looks like you were not receiving a charge in the first place so the tab can simply be dead of juice.
Yes, the first time I turned it on I saw the battery, but when I turned it off, I never saw it again, even in this 10 hour period that has been charging on different outlets to see if the outlet is the problem.
Even I used a pencil tipe voltage tester, that tells if an outlet has voltage current, and the voltage could be felt around the tablet when charging.
But the screen does not turn on when pressing the button, nor touching the screen.
as a test, use just the usb plug and connect it to your computer. it shouldnt receive alot but see if that will initiate the screen turning on displaying the battery.
No, it does not turn on even when conecting it to the computer, it appears a message of no controlers found in the computer, but the divice does not turn on at all

idk then man, it could be the wire or it could be the tab itself
Besides something wrong with the GTab, I guess it could still be a defective cable.
Yes, it could be a possibility, that the wire is bad, but also, I can mention that in the time it was on, and working, I exchanged a couple of photos for my wallpaper, photos that I took with my camera long ago, so, if conection means, the cable I think works ok.
this happened to me.. tab is finished, send it in for repair and you will receive a refurb....

Did you press power and volume down at the same time for at least 31 seconds for samsung logo to come on?

I've tried with the volume key and the power key at the same time for almost a minute, without being conected to the charger, and being conected, also tried conecting it to the computer, and downloading the drivers that samsung offer in the support page, and samsung kies, but they don't recognice the device, when checking the hardware of my computer, I see inside the tab of "other devices" one called APX that I know that is my tab, and says no controller is assigned to it.
Mackie, yesterday (today) I chatted with a support agent of samsung until 2am, trying to see for a solution, but he couldn't find one, so, we ended up in making a request for service, to use the warranty for them to repair/give another machine to me, but, I don't want to do it, because, it would be enormously expensive for me (100$ for a Costarrican is very expensive) so, I'm trying to find a solution to the problem before I send the tab to the US with a friend that lives there, so I can use the warranty, but that courrier charges would be really expensive for me.
In summary, I'm trying and trying to look for a solution, testing your comments and suggestions, and also at the same time looking for myself for an answer.. before december 8, when I plan sending my tab if anything works.
Once, this happened with my nokia e71, but because it ran out of battery, and won't turn on again, but... cellphones are easy, you can change the battery, and actually, it worked, and when I had time to take him to repair, they checked him with the old battery, and it worked again... Tabs are horribly sealed tight and I would lose the warranty if I try to open it to change the battery, and it might even not solve the problem!
i don't know if this would help.
I had the same situation and i thought mine was dead.
I pressed the volume button as long as i can. Took about almost a minute.
Sorry if this doesn't help
people please read previous comments, Coliner has stated numerous times in different posts that he has tried the power+volume method and has had no luck so please stop suggesting it
Coliner, the only other thing short of paying the money for the exchange/repair is to attempt using a different cable. you stated before that you used both the usb partial charge and the actual A/C charge method and have received no results. The only thing I can suggest is to try a different cable, if anyone else you know has pretty much any of the galaxy tab (7", 7+, 8.9", 10.1", 10.1v) then you can attempt to charge it. Or hell, see if any store has any of them on display charging, explain your situation and ask to let you give it a shot and if it works buy the cable from them if possible.
Short of prying the thing open to play surgeon, these are your only options.
NyPlaya, today, I'm going to the capital (the only place you could find something similar) and look for stores with tablets, and also directly to a samsung store, ask for a charger, and to see what happens, and try again to turn it on at my house, I've let her charging for 2 days now, continuosly, lets hope it worked!

I re read your post and i think we missed a big clue. You said you can see APX device in control panel. Apx is nvidias debug mode and in this mode (usually reached via power and volume up) the screen is blank. it is waiting for nvflash command. Check this thread for more info http://forum.xda-developers.com/showthread.php?t=1324461
So wonder if volume up button might be stuck
Sent from my GT-P7510 using Tapatalk
Well, I tried the procedure, and got to step 17... How do I run that command, how, where? so I then uninstalled the controler, and now not even the APX error appears, and tablet is still dead!
Also I went looking for chargers in stores, and they did not have chargers! so I couldn't test it!
I was searching in other forums and found this other clue:
Taken from http://www.htcmania.com/showthread.php?t=274687 post #14:
"What you run "dead" after having it at night charging, is something that unfortunately is still quite common. It happened at the beginning and pulled by soft reset, ie power button volume button -. It has happened a few times and this has been solved. I think it is related to removing the charger. Unplugging from the wall and then the tablet does not usually fail, but if you disconnect first tablet, it "dies." I tried also to turn on the screen before unplugging and so has not failed me to unplug the tablet first. Clearly a bug, I do not know if Samsung or Honeycomb, but obviously it is a pretty annoying bug. regards"
I remember I did that same thing! because my tab was conected to the PC, and I discovered it was not charging, I conected her to the AC in the wall, and without taking the 30 pin conector out, and boom, never again it has turned on!
I continued searching and found another method, power button plus volume- 10 seconds, release and volume + for some seconds, then conect to PC, and the driver appeared again, in this case Nvidia USB boot recovery
I continued to try the method shown to me by animatechnia, and typed nvflash --bl bootloader.bin --go, it says then:

READ THIS, IT'S HAPPENED TO ME
Shortly after buying my tablet, before rooting, my tablet was charging and would NOT turn on. I read somewhere to do this:
Put your finger on the screen while holding the power button for as long as you must.
Don't let go til it comes on.
Edit: best of luck if that doesn't work. Things like this suck.
First time I tried with the finger, I forgot to disconect it, so, my pc started making sounds of conected device, disconected device, just like an USB stick, then I took the cable off, and tried for more than a minute both finger and power, and nothing happened

i tried to do all instructions posted here, but i can't do anything to turn it on. no matter what combination of buttons i tried didn't work. i have time until Monday when i was planing to ship it back to amazon to try to revive it... anyone has any idea...
it doesn't react on anything, it doesn't make any sound when i plug it in usb in pc.... just nothing!!!! please help me!!!
This just happened to me yesterday. Have you tried holding the power button for more 15 seconds to force a shutdown and then wait 5 seconds, then hold the power button for 4 seconds to turn it on again?
If that doesn't work (as was in my case), get android screencast (available here on xda) and see if you can view the transformer screen on the pc (must already have usb debugging enabled).
Using the screencast I figured out my screen was dead (the touchscreen was working with my fingers but screen showed nothing). I just sent mines off for RMA today...hopefully this won't be the case with yours.
thank you for your reply.....
unfortunately pc doesn't detect transformer at all.... i am desparate
Are you sure the transformer is on when connected it to the pc? I would hold the power button for 15 seconds to force a shutdown, then connect it to the charger for about 5 minutes so I know its def on. Then connect to the pc and see if the internal storage shows up.
If not, the other option is to test it using a hdmi cable....and if that doesn't work then it sounds like your transformer is not turning on at all which either means the battery is dead (needs charging) or the device is completely broke!
it is final - the device is dead.... on the bright side i can still return it to amazon....
sorry to hear...well at least you can return it to amazon. I'm going to have to wait for Asus...and whats worse is Im leaving to go back to the UK in exactly two weeks (what timing!!). If it doesn't arrive back on time I'm going to have to get someone to mail it to me.
On a side note its odd how the device's are dying...I've come across a couple of cases while googling and I was extra careful with mines....bit woried about my replacement. As much as I hate to say it I'm considering selling on ebay and getting something else (not Galaxy tho...cannot live without sdcard slots).
i have the same problem, what tablet to take instead of transformer.... if 10.1 had a sd card slot it would be my choice.... maybe i should wait for toshiba....
connect via usb cable to pc ( ON) let it sit for 6-8 hrs and try again. If your charger is not working, you may have killed battery. If TF turns on, turn it off so all of the limited current is used to charge battery.

Thats a good point...I would suggest you try that Klokom as some people have found their charger pins to become loose or their chargers just melt and die.

The toshiba does sound interesting, and theres also the Lenovo K1 and Sony S1 too. Will have to wait for the reviews to come out to decide tho.
i'll try that....thanks....
although i doubt that it is a case, because when i left work yesterday it had around 40% battery and when i came home it was off... but i'll try that...
Hold power for longer than 15 seconds, every person in the world sucks at counting in their head so hold it for 30 seconds, then try and turn it on, if that simply doesn't work and usb doesn't give you anything try charging your tablet overnight. If still nothing return or RMA it.
Didn't even flash or root yet and my 32 grey GT died last night. It had been working great and was getting ready to flash pershoots kernel this weekend. Last night I plugged in after shutting it down like I do every night. Today when I went to turn it on nothing. I tried holding down the power button for a while and still nothing. I tried holding down volume buttons with power for extended period still nothing. I even tried plugging into different outlet to see if something happened with outlet and maybe drained the battery overnight. Luckily I got it from Fry's two weeks ago on Friday right when they came out and Fry's has a 15 day return policy but this makes me a little concerned... and that's cutting it a little too close.
Has anyone heard of things like this happening with the GT? I'm thinking I may need to see if they'll still sell me the extended warranty. I babied this thing and hadn't even flashed anything on it yet. I'm a little concerned about the reliability of the hardware... I'm not usually the one with the needle in the haystack device that goes bad but who knows... I'm already in withdrawal without it.
Is there anything else I can try before I take it back? Maybe try plugging it into the computer instead to see what happens? I can't really see what else I could do since this thing doesn't have a removable battery. If it won't power on I can't imagine there's much I can test with the SDK dev tools from the PC using the usb cable?
plugged it in with usb...
I do hear the sound of a device being plugged in on win7 when I plugged GT in and got the driver message in tray. GT still won't turn on. When I hold down the power button every about 6 seconds my windows machine machine makes the same sound you get when plugging in a usb device in addition to an extra sound at the end.
[email protected] well I guess it's going back tomorrow.
You got the sleep of death. This is a honeycomb bug that i have personally experienced in the xoom, transformer, and the GT. The way to fix it is to unplug the GT, press the power button down by itself and hold it until the you see the screen turn on and startto boot up. It may take 15 seconds or more.
If that doesnt work, plug it into the wall outlet and try the process again. If that fails also, unplug it again and try the process once more.
That combination seems to work for everyone. The only exception would be if the battery is completely drained. You would need to plug it into a wall charger for a few hours and let the battery charge, and then try the process again.
I dont know why this hasnt been fixed by google yet, its really annoying. I thought 3.1 would fix it but it didnt.
you should have post this on the general thread, but why dont you return it for a different one? problem solve...
Android Development is not for your Questions or Problems Please post in the correct forums
Moving to General
I think you got the battery drained .. for some odd reasons the android has leaky power consumption even when shutdown on occasions ..
Charge it up for a while .. wait .. correction LONG while ..
Hope that is the problem
Exactly the same problem, I have tried the hold power button but it is not working... any other work around?
Please Help
I chatted with a rep from Samsung last knight and he told me that I needed to leave the Tab charging for at least 6 hours and then try again... so I'll let you know if that did the trick... hope it does...
I've actually had this happen on two different 32GB Galaxy Tabs (the original one I purchased and its replacement). After powering the device down it would not boot up.
In both cases it happened about 3 days after receiving the tablet and with 80-90% battery charge remaining. I tried additional charging, holding the power button down for an extended period of time, and attempting to boot into download mode - everything failed to bring it back to life.
I'm not sure what triggers this condition my only suspicion was that it may have something to do with enabling encryption on the device. On the second tablet I didn't have time to do much customization or install many apps but it ended up dying shortly after enabling encryption.
Wow. This happened to me yesterday with my 16gb from Sprint. Had come unlocked,yesterday 3 days in, died. I tried all the suggestions above to no avail.
Took it to corporate today. Now waiting on replacement.
bumming*
Hope next one is unlocked
Edit**** worked. Lol. Guess I didn't try it again today after I tried charging it last night.
About 15 to 20 seconds and she's back!!! Excellent! ! Thank you so much.
Not sure now whether to replace it.
With another.

Hi everybody
I have a problem with my Galaxy S5 (no custom rom, official)
I normally used my phone, I locked it. But, after about 10 mins I tried to unlock my phone, but nothing happens
I tried to reboot, nothing happens. I tried take out and put the battery - nothing happens. So I searched on Google and tried some keys combinations, but nothing happens. My phone has about 80% battery. I tried to charge it in the charger, but nothing is happening (black screen, no notiffication light). Also I tried to put off my SIM and SD Card, but nothing happens
Do you have some skills in it? Can you help me?
Few days ago, I faced the same problem..
http://forum.xda-developers.com/showthread.php?t=2853472
Then I'd to take it to the Samsumg store.. And they return it back in 2 days and said me it was a software problem..
I wanted to do a recovery reset, but i can't boot my phone anymore, also the Kies doesn't see anything, so. Did you really think that is a software problem? Because my phone won't vibrate at boot. So maybe it can be a hardware prob :/
EDIT: Phone started blinking red light... (nottiffication), I tried to charge it, but nothing...
Mate as mentioned early, same problem I faced..
It'll be better, if you return it to Samsung customer care..
You seem to be saying that the problem occurred unexpectedly. So presumably this isn't subsequent to a flash error, newly installed app or a trauma (dropping the phone, etc).
First ensure that your battery is charged, plug in the phone to a charger as well and try turning it on. If at all possible, borrow a battery from a friend's S5 or go to a store and borrow a battery for 30 seconds to confirm that the battery isn't the issue.
If the problem persists, then remove the cable and battery. Then put the battery back into the phone and press and continue to hold in this order, the volume down key, then menu key, then power key. Hold all three until the screen powers up (about 5 seconds). If this doesn't work.. the most likely problem is a damaged power key - try pressing hard or "wiggling" it to see if that makes a difference.
If you still can't start the phone, then see if a local cellular repair shop has a "jtag jig" that you can borrow. Or you can buy one on Ebay for a few dollars. When this jig is plugged into the USB socket, the phone should automatically restart.
If all of the above fails (which is unlikely), you would seem to have a hardware problem or unknown origin. Which would be very unusual. If your phone is under warranty, make a claim. Otherwise get an estimate to repair it.
.
If I hold all 4 buttons at the same time and connect the phone to PC, PC recognises the phone for a few seconds. Well, maybe not recognises, I cant see it, but it plays the same sound as if connected flash drive to pc. However, everytime it disconnects within a few seconds...
I´m in the same case, but I was flashing the Galaxy S5 with the four files ROM and the pit file using Odin3.09. All the process ended well, but after rebooting there apeared one Screen sayin something like "Some files at this phone are encripted and there can´t be modified......." so I did a manual reboot and take off USB cable and from this moment the phone don´t do anything but giving a sound when I plug USB to computer cable and I can see new COM --> Qualcomm HS-USB QDLoader 9008, and there repeat a loop.
I´m still looking for a solution, but it gives me that there is time to change phone.
Possible Fix
This thread is old but idk if this was ever solved, so in case anyone else ever has an issue like this. My Gf is still rocking this phone so i've had a little experience with it. The phone wont turn on or charge. I got it to work by sticking a flat head screw driver and prying it fairly hard against the bottom of the battery (the side closest to the charge port) and forcing the battery harder against the metal contacts. While pushing the battery I turn on the phone and it starts right up and continues to run even after letting the pressure off. I've noticed this happens every few times i take the battery out, but this method has never failed for me turning the phone back on. Hope someone finds this helpful.

Hi everyone,
yes this may seem at first similar to several other posts, but rest assured, I have googled from one end of the galaxy to the other and so far no solution has helped me.
Basically, my N7 a month ago was bootlooping loading android, this has happened before and usually i just re-load the factory image and i'm good for another few months. This time however, I was busy and said, no problem, i'll load the image in 2 days or so. By then, my N7 appears off and does not react to me pressing the power button or plugging in the charger. My assumption is it was in my bag and kept bootlooping and eventually drained the battery.
On my google searches, i've noted that there is a huge issue where when the battery drains completed, it is a pain to get it to turn on. Most people seem to be okay letting it charge for a while and holding the power button for 30 seconds or so. I've looked at google's official video about this issue and their steps to fix it, and i have not gotten any of this to work. I've held the power button for not 30 seconds, but several minutes until my finger became sore and it won't turn on. I've also done this holding down the power and the volume up button, volume down button, both etc. all combinations. I've left it on the charger for days and when i unplug and re-plug the charger, i don't get a hint of the screen powering on, let alone the battery charger icon you are supposed to see. I've tried this with my other chargers as well. The n7 charger is fine, i use it for other android devices no problem. If i plug this in the computer, i get a driver install failed error as well.
I've gone as far as taking off the back cover and double checking the battery connection which apparently gets loose quite easily and this is fine. I know my charger is fine, because i use this charger for other phones and they work fine, i've also tried using the usb cable to the computer and that does nothing either.
I would rule out an issue with the usb port on the device itself, because i have the dock which can charge the nexus 7 from the connections on it's side, i think it would be highly unlikely that both these pieces failed.
I am at my wits end, i really liked this tablet and want to salvage it as best i can. Only thing is i can't really do anything with it, all my google accounts are saved on this device and i'd rather not reset all my passwords if i attempt to sell this for parts.
I'd like to know if anyone has any other recommendations on what i could try, even if it is swapping out hardware inside the device. If i can salvage and sell this for something, i am willing to do that, i'm just not sure if it's something with the hardware at this point or if it's that dreaded battery drain issue.
Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!

let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.

Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.
