Galaxy Tab 7 Won't Turn On? Here's a Fix it!

I've tried all of the other fix its to get my Galaxy Tab to work. I've tried charging for 12 hrs via wall charger (no response)... I've tried holding the power button plus home key while tapping on the screen at the same time for over 2 minutes (no response) ... I've even tried putting it into download or recovery mode by holding the power button plus the volume key (up or down) for over 2 or minutes (no response) ...
If you're like me and thought the manufacturer was your only option left, there is one thing left you can try.
All I did was remove the shell and unplugged the battery for 30 mins, plugged it back up and viola!!! I have the battery charging icon. And it now boots perfectly into the OS.
Its worth a shot.... here's a video I watched to learn how to remove the shell.

Note: you will need a tri-wing screw driver to remove the first two screws. I didn't have one and just used a precision flat head screw driver and it worked like a charm if using enough down force so you won't strip the screw.
Hope this helps someone...

Battery removal resets almost everything -- I'm grateful for your confirmation that it works on the Tab, and also for your links to the hammerless teardown.

XDA forums has helped me so much, so I'm glad to return the favor to those that need it!

good find
not had the problem myself, but that info is now in my brain for whenever I do have a problem

Good. Thx man!!!

Many thanks man, this saved my (tablets) life. Switched off my tablet last night after charging, for the first time in weeks, just to refresh everything. Tried switching back on this morning and nothing. I've spent all day trying to find out what the hell was wrong and tried all the various button solutions others have mentioned. Nothing worked. came across your info and links and thought I'd give it a try as I had nothing left to lose, tablet was dead. Voila!...back up and running again. I won't be switching it off again in a hurry. Once again great info and much appreciated.

Nice info, really helpfull, my friend gtab p1000 have some problem, wont turn on, and i found this thread, i just try once, and amazing its working, i hit thanks to you

My have turn off and dont turn on, i wiated 2 days and plugged in wall charger, and they work again.

dead tab
still got no luck...i'm tried of your skill yesterterday n my tab still won't turn on...

thanks for the advice
hai, i saw your posting and thank god it really helpful. i own a p1010 and some how it cant turn on twice!. what ever i do, and what ever tricks available in the internet i had tried it all, all with no success. so the first time around i had to sent it for repair and because my tab's warrant had already ended i had to fork out a lot just to make it running. the repair shop just stated that the battery and the touch screen need to be replace. how stupid of me to fall for that. after that my tab is usable again. then it happend again. two days later the same problem occurred. now i know it is not the hardware but the software that causeing all this headache.
now, with your posting, i opened my tab, disconnected the battery for 15 minutes and walla my tab is ok again. phew...save me a lot of money.
i see that the problem might be in the software. i see that alot of p1010 owners face the same problem here after upgrading from froyo to GB. and i notice that the blank screen syndrome would happen if we put it in a standby mode (my standby mode would be you touch the power button once just to make the screen goes blank).
just my 2cents.

Hi, I got same problem with you guys with my P6800. Tried all those methods (execpt those removing the casing/battery). I followed one tip and it works. Press and hold the power button for 20 second and release it. The screen displayed an image (icon?) of battery and clock. Some said it also work by pressing the button for 10 second.

thanks for the advice guys
holding the power button works
but my question is why is this happening?it wasnt happening before?

guys
does no one know whats causing this? is it a firmware issue? or battery?

for me, this happens every time I use the Netflix app. if I don't go into task manager and clear memory after every use of Netflix, my galaxy tab will not turn back on. sometimes fully charging it will wake up the screen, but that's not helping today so I guess I need to remove the shell even though I don't want to. I miss pocket PC's with soft reset buttons!!!

How are you sure that the battery is good and charged. Normally after one year if the usage is heavy, the chances of battery down happens. So make sure battery is good. Secondly you mentioned volume down button, how about vol up button ie recovery mode?

This happened to me as well last week. Tried everything but failed.
I did below steps and my phone is up & working
1) Remove the battery and keep it in a dry place for 4-6 hours (Very important step to make this work)
2) Place the battery back into computer and do not turn ON the phone
3) Plug the phone to wall charger and charge the phone for at least an Hour (I kept for 2 Hrs)
4) Remove the charger and gently press the power button for 15 secs
5) This should turn the phone back ON
Above steps helped for me. Let me know if this worked for you also :angel:

Ankush,
In your case I can think of only 2 things
1) If you have CWM installed then
press and hold "Volume UP Key + Power Key + Home Key" all together for 30 secs (may be a min) and see if you get recovery screen
If yes then all is ok & you just need to flash a new ROM
2) If you do not have CWM then
press and hold "Volume Down Key + Power Key + Home Key" all together for 30 secs (may be a min) and see if you get a custom screen
If yes then you can install custom ROM (or original ROM) using ODIN.
Let me know if anything helps you here
Regards,
Israr

This step kinda weird.. Since I my note never get wet. I hope it will work.. I tried it later.. I dont have much budget to upgadet to Note 3 now. :crying:

Same kind of error
Over the night my phone closed. When I try to open it, on the screen apeared "Insert PIN to decrypt your ~something~ ". I never encrypted my phone so I tried to restart. I got stuck on the samsung logo. Then I removed the battery and put it back in and my device never started again. I have 2 batteries and none of them worked. I can charge the batteries independently and this is not the issue.

Have the same problem right now.. did you find a solution eventually?

Same happened to my device today. Had trouble with some apps before. Wanted to play back a two days old backup. But my phone never woke up again. Shut down forever. Never got to recovery. Had the latest cm11 nightly. Now its dead! RIP. My dear friend. We've gone a long way together. Never intended to replace you anytime soon. But I can't be without a Phone. Moving on to Galaxy S5 now. Hope it can fill the gapp.

Same here, completely dead after a reboot. I took it apart but I see no damage or signs of burn damage anywhere on the motherboard or other components. Is there anything I can do to troubleshoot and find out specifically what happened?

i am not sure, mayb the phone is design to last for only certain years, new apps launch make the phone in applicable for be running with latest apps and everything. Or mayb the phone is design with a timer to self destroy its chip or component after specific numbers of days being used??

[Q] My Moto g 2nd gen got switched off while encrypting and now not switching on

Hi
I need urgent HELP.... Its my new Moto G 2nd Generation which I brought around 1 month ago. I was trying to encrypt my phone using the option in settings. It went perfectly fine till it shows 100% . Then it got switched off and now no response. I tried charging it up. Not working. Then tried to get into recovery by pressing power button and Volume + also Power and Volume -. No change. Did I bricked my phone? What shall I do? Its still in warranty, so giving the phone to service center helps?

Did you enter recovery before? Look at the following video and see if you can enter recovery:

Thanks for the reply.....
Thanks for your fast reply. I tried the same method but it didn't work at all. I kept my phone at home and after I came back from my office I just plugged it to give it a try. I guess my battery was fully drained, when I plugged it charging screen appeared. :laugh: A small hope came and I kept pressing the power button and Volume down for sometime and in between Volume up also. I guess Its my lucky day today, phone booted into recovery screen and I just selected normal power up option and I got all my data back. ..... You don't have an option to take your battery out and put it again. Other wise I won't be facing this situation....... Thanks for all.

you always hard reboot your phone by long pressing power button.

phone dead

all of a sudden galaxy s6 died. it was about 70% charged, i received a call of about 5 minute length. then i just placed phone on my desk. i picked up the phone after about half an hour to make a call, and it won't turn on. I thought battery may have been drained for some weird reason, so let me charge it, but after connecting to the charge, i don't see charging led come up. still kept phone in charge for about 20 minutes, still it will not power up. The phone "was" on stock release, haven't rooted or anything like that. it simply went to heaven. :crying:
called up t-mobile, at least they will send a new phone, but what will be the life without phone for next day ?

hold all four buttons (power, vol up/down, home) until it reboots. this happened to me a few days ago (assuming it's the same issue)

thanks master, that worked, but what could have caused it ?? when customer service wanted me to press vol+up, home , and power button, it didn't work, but holding all four worked, so puzzling ! anyway, they are sending me the replacement, so i think, i will swap the phone.

i know it is a pain to set up a new phone, but i don't want to take a chance, if this has happened once, it can happen again. it may be that hardware has some issues like loose pins or something. I have never paid attention before, but now I remember that sometime when i connected it to charge with the supplied quick charger, it will just show "cable charging" , and rest of the time it will show "fast charging". So, this may have something to do with that.

XT1095 suddenly switched off and wont boot

I have a problem with my Moto X 2014 - XT1095. Phone was fully charged and in the morning suddenly went off and wont come back on after that. I have been over 24 hours now without a phone.
I have tried to force restart and done external factory reset as mentioned here: https://motorola-global-portal.cust...prod_answer_detail/a_id/101072/p/30,6720,9197 and the same problem is still there.
When I press and hold the volume down button and the power button at the same time while plugged, a green light blinks briefly in the middle of the top speaker grill and nothing more happens.
This phone is about 6 months old. Can anyone help me solve this problem and get the phone back?! :crying:

It sounds like your battery died and might need replacing. Does it attempt to charge?

When plugged to the mains, nothing happens but when plugged to the computer, green light briefly show up in the middle of the top speaker grill and computer makes that connecting sound.
Cant also get to boot Mode Selection Menu

Please give us some details. Which rom did you use? It was a custom rom or the stock one? Did you have an unlocked bootloader? Did you have installed a custom recovery or not?

I was having stock ROM, never rooted and no unlocked bootloader. This is a vanilla device and totally untouched.

Using moto's charger, charge your phone for about 2 hours. After this time and while your phone charging, press and hold power button for about 3 minutes and see if your problem solved by this way.

Maybe i'll have to do this again but unfortunately that hasn't helped earlier when I was advised to do this by Moto's support rep

I have tried that again @Jim_C30 several times and the phone is still dead. Any hope for this phone anymore?
Would have been nice if the computer recognise the phone and at least can try and flash a ROM to it

Without charger hold the Volume Down and the power button together for at least two minutes. Is there any difference?

thanks @Jim_C30 for your assistance. Unfortunately no difference ?

Is your phone under warranty? I read that is only 6 months. Why don't you visit a Motorola Service Center?

well yes that's where I've got problems... bought the phone in the US and I'm now in the EU so warranty only works in the US. Sending it to the US is impossible because of lithium battery inside the phone ?

I am more than sure that the warranty is global. Make a question at motorola but i think that i am right. The warranty is global not only at the place you bought the phone. They could find anything by your imei.
Do it, don't be scared!
Just make a question...

thanks I've asked already Motorola before I came here for assistance. They said it is having only US warranty. Motorola's warranty isn't global anymore unfortunately. I've to send the phone from here to the US for repairs - this is just terrible from Motorola.

exactly the same problem here and at the same moment, yesterday morning

I have the same problem here. Do you find any solution ?
It is stock ROM, never rooted and no unlocked bootloader.

Solved for me :laugh::laugh:: I disconected the battery for about 10 days. Then I conected it again and with the solution " press and hold the volume down button and the power button" but for about 3 minutes, and MAGIC
I've tried this like 5 o 6 times during 2 weeks but at first I only saw the green led on at the top of the screen and a vibration but finally it tuned on yesterday!
This problem was produced after two hard resets due to the hard battery draining cell stanby
