I did a soft shutdown and now it won't turn on. No response to Vol UP + Vol DOWN + Power. Nothing but black. Its connected to power and was at 80% when I shutdown. USB debugging was enabled. Any hints? Thanks, -RP

Ugh, I had to hold power button for 30 seconds. Its really excessive. Delete this please. Thanks.
funny thing is the old nexus 7 had the same issues
I received mine today and it wouldn't turn on at all. All I got was a flashing white light after holding the button to turn it on so knowing that the same thing was common on the previous generation N7 I tried the 30 second trick with no success so I figured I'd share my experience.
Turns out my battery was at 0% out of the box. It was so dead I had to do the following to actually get it to start charging unfortunately:
1. Open it, I followed the guide @ ifixit: http://www.ifixit.com/Teardown/Nexus+7+2nd+Generation+Teardown/16072/1
Note: The plastic bezel surrounding the screen is incredibly soft plastic I just learned. Even using plastic pry tools I ended up leaving marks the plastic, despite being extremely careful.
2. Disconnect the battery (follow the guide above)
3. Press the power button and hold down for 10 seconds, but don't release yet.
4. Using the supplied AC adapter, apply the power and continue holding for another 10 seconds.
5. Reconnect the battery while the AC adapter is plugged inThis should get you to the point where you at least see the battery charge icon on the LCD. I waited another 30 minutes before moving on and powering the device on. I intend to leave it charging to 100% before I do anything else with it.
I remember on some older devices I've had when they got into 0% state, they didn't want to take a charge from a high power charger and I needed to switch to 500ma USB 1.1/2.0 slot on PC and let it sit a while before it would trickle in enough charge to get some life.
After that it would take charge from any source again.

lol - this happened to me too. Except double whammy - as soon as it was charged enough to turn on, it wanted to do the system update and wasn't charged enough to do that. Back to the USB it went!
Well I got my replacement for the one with the dead pixels, it started up fine and I even configured just to check it had no dead pixels. I had to step away for a few minutes and it was off, completely dead. Tried ever variation of tricks and I get nothing, no white LED, no charge indicator, nothing.
I think I'm sending both the replacement and the original back for a refund, this is just unacceptable at this point.
I bought one but returned it after 3-4 days. Mine was fully powered and I would go through the shutdown procedure. The device would power off. Then I tried to turn it back on. It would not work. I held it down for several variations of time: pushed it quickly, help the power button in for 10 sec, 15 sec, 30 sec... I found that when I connected the device to power through the usb the screen would show 100% charge right away. I would then hit the power button and it would turn on fine. I immediately unplugged the device and everything was fine. i powered it down again and repeated this process 2-3 more times before I said the heck with it. Anyone else know of this issue or did I just have some crazy unit?
I have the LTE version of the G Pad 8.3. I have TWRP and an unofficial CM11 on it. I left it on long enough for the battery to be drained and now it won't turn on at all. I have plugged it into the charger for over an hour. The power button does nothing, holding Vol - and Power does nothing. I am at a loss. Any advice would be appreciated.
I'm experiencing the same issue, although I had twrp and a stock rom. It ran just fine until I let the battery run out.
I have tried power + vol down with no results. I have left it on the charger for several hours as well.
Thanks in advance for any help...
I have shipped mine back to LG for repairs. I will let you know how it goes.
How did the repairs go?

This worked for my VK810... my tablet was unresponsive "dead"
1. Hold the power button and the volume up/volume down button (directly in the middle/center of the volume +/-.... So right between the two! Not one or the other, middle so both!) for 20 seconds...
2. Keep holding the middle of volume+/- and power button and plug tablet into usb wall charger.
3. Release both buttons.
Hope this helps!

Oh, this actually works.
This happened to mine a few years ago, but no button combo would power it up and it would not pull any current when trying to charge it.
I think it drained the battery beyond what the internal protection circuit would allow. I had to open it up, de-solder the battery and force-feed it a 4v for a couple minutes.
Soldered it back together and it started charging normally and booted fine. I've had similar problems with other cheap LiPo powered devices; charger packs, Bluetooth audio modules, etc...
Hi there,
Earlier today I plugged my tablet in to charge and left the room. When I came back, the screen was on (very dim) with the Samsung splash logo running. The tablet does not react to anything. Holding the power button changes nothing (so it doesn't turn the tablet off). I unplugged the charger hoping the battery will slowly drain and turn the device off for me. Any tips?
My device is rooted btw.
e: holding power, volume up + down for a few seconds made the tablet reset. All fine now.
I'm experiencing the same behavior meanwhile on two different German SM-T800s. Both have been charged, diconnected (everything still OK) and lay unused for a few hours. Upon picking them up, the screen displayed the above mentioned Samsung Logo.
Here are a few facts about the Tablets:
Purchased and made a OTA update to LP (5.0.2)
Rooted using CF-Auto-Root
Kernel: 3.4.39-4620222 [email protected] #1 Fri Apr 3 09:48:41 KST 2015
Buildnumber: LRX22G.T800XXU1BOD1
SE for Android Status: Enforcing SEPF_SM-T800_5.0.2_0022 Tue Jun 23 14:43:13 2015
There haven't been any updates or modifications of apps or Android itself, which might be seen in a causal context.
As Grawl mentioned the tablet doesn't react to anything. I tried the following on one device
Long press of power button
Power button + vol up + home button
connecting to PC via USB, device is not recognised (Kies is trying to establish a connection, but eventually failing)
connecting to a usb charger
I noticed a significant generation of heat right between the camera and the Samsung logo on the backside, I normally only notice when I've been gaming for a long time. Both have the original Book Case Cover attached.
I decided to let the tablet discharge and see what happens. After letting it lay overnight, without the cover I was anxious and again tried to press power button + vol up + home button and this time the screen went blank and the tablet booted up, which felt a bit longer than usual. I've started the tablet a few times since and everything seems to be back as before this freeze up.
Could it be a 'heat' issue or does anyone have a clue as to where we might look for a cause? Any help is really appreciated.
To add more information:
- I also updated to 5.0.2 using OTA update
- Also rooted using CF-auto-root

I don't think heat was the issue (in my case). It was a rainy day with temperatures of around 20C. The week before I used the tablet outside, when it was 35C+. I made no changes or installed new apps 24 hours prior to this incident.
I mentioned 2 devices and was expecting the second one to be handed to me by my parents. But they took matters in their own hands.
They let the SM-T800 drain the battery and connected it to a charger when the screen was all black (no Samsung Logo anymore). They told me that the green battery symbol appeared, just as it does on a switched off device that's charged. Unfortunatly it wasn't possible to see what would have happened, when the device would be fully charged, as my mom, in her infinite wisdom, decided to boot it into recovery mode (as I had asked her to try that two days prior , which didn't result in any reaction at that time). After choosing 'reboot system now' the T800 started flawlessly and continued to work in that way since.
Still no clue as what might have caused that.
cross posting but we can't delete so:
it just happened to me right now, what a rush ! finally , holding power, volume up + down for a few seconds made the tablet reset
( while connected on usb) once booted the battery was at 60% , WTF was that ?
I had a similar issue. As of 13 hours ago my Tab S was fine. I went to go use the tablet maybe 4 hours ago and I saw the screen dim and samsung logo there (just as was the case with the OP). The tablet had been in my bag, so maybe it accidentally rebooted or something while it was in there?
I did the power button + vol up + vol down reset trick and on reboot it worked fine. It was at 7% when it rebooted :S, but it was around 37% when I was using it last so this makes sense.
I also have a rooted tablet running stock...
Hi, I am desperately trying to revive my Tab S 10.5. It went blank a couple of days ago, the battery should not have gotten empty, but my first action was to plug in the charger. Didn't work of course.
Then I googled and ended up here. I have tried various button combinations, with charger connected and disconnected. Also while connected to my computer, but maybe Ubuntu doesn't count on this occasion.
I fear I wasted my chance for the magic power + vol up + vol down by trying other combinations before it.
My only hope now is if any one of you wizards could talk me throu a magic spell for reviving my precious Tab S 10.5 LTE, or maybe link to an howto guide. Please :-\

Plug the charger in hold POWER + VOL DOWN.
Hopefully you will see your tablet restart.

Thank you very much for the reply. Unfortunately it does not work in my case. I am not sure which one is volume down so I plugged in the charger and held power + one of the volumes for about 20-30 seconds. I then unplugged, waited maybe 10 seconds, plugged the charger back in and held power + the other volume, also without succes.

Leave your charger plugged in for a while. A totally dead battery will not be able to boot the tablet until it has some juice. I'd also check the charger or swap it.
After a short while try again. VOL DOWN is the one closest to the power button.

Thank you, but still no luck. Trying another charger now but the other one works with my phone so I don't think it's the charger.
Open tablet up at own risk. There is videos on YouTube how to do this. Take out battery wait 3 minutes, plug it back in. Press power button. Should work if not try 3 button combo as above

But need time and tools so not tonight. If any one posts a miracle tip before I crank my Tab Open, I will stick i sign with the screen name of that person in the ground of the moon, whenever I get there.

Impatience is my nightly name. I got the back cover off, it was Hard on my finger nail but even harder on my nerves. Then I fiddled with some incredibly-fragile-looking cables and got the battery out. As I am writing this I'm letting the residue energy disappate from my Tab corpse, before attempting resurrection. I did hold the power button 20-30 seconds after removing the battery.
Note, this was tougher on the nerves than replacing the camera module on my LG G4, wich was fairly easy.
Now, by the power of geeks and The starship Enterprise, Reassemble!

Note, The tiny cover for the Ir blaster came off, keep your eyes on it. I got it back fine thou.
However, plugging in a charger and holding power + vol down still does nothing magic. Thinking I'm to leave the charger plugged in over night.
Nope, still can't get my Tab to liven up. All hope seems lost

Yea that is the next step for me. I'm not entirely sure it isnthe battery so I'm sending in on service. I really liked my Tab S, a bit sluggish but still, I want it working.
Thanks for your time everybody, I really appreciate it.
This morning, I turned my phone on and it was working just fine. I put it on its charger and left it alone for about 30 minutes. When I came back, my phone seems to be dead. So far, I have tried:
Holding the power button for at least 1 minute
Holding the volume down and power button for at least one minute
Holding the volume up and power button for at least one minute
Holding both volume down and up and the power button for two minutes
All this was done while the phone was hooked up to a charger. So far, there is no activity at all. The screen doesn't turn on and I cannot connect the phone to my computer. Does anyone have any advice for this situation?
Update: There is a bad burning smell coming from the charging port and the charger, I think my phone is done for.
That doesn't sound good hoss. Might wanna try warranty?

Good Morning,
I have a big Problem with my M8, it wont boot anymore. Yesterday evening my phone shut itself down because of low battery and I let it charge over night on a wall charger. But It wont boot, no matter how long I press the power Button/Power Button+Vol. up/ Power Button+Vol. down....
When I connect it with a charger, the orange led is turning on and the battery with the lighting inside on the black background is turning up. Nothing special until now. But it doesnt stay in this state, after 3 seconds the screen gets black and the orange led ist turning off for 1 or 2 seconds. After this the same process is starting aggain. The Led is turning on, the battery icon with the lighting poping up.....
Is my M8 dead or does someone know to fix this?

I don't know how long you are trying to push the buttons (always help for you to be specific as possible when asking for help). But try holding power button only for a minute or more, as that is the length of time required in some situations. Many folks (myself included) have freaked out, thinking the phone won't power on, as they don't realize the button needs to be held for that long (and a minute is a pretty long time to hold the button - maybe a bit counter-intuitive).
If still no change, try a different charger and a different cable. Maybe the phone is not receiving proper charge.
I'm confidant you don't have a "brick" (such as damaged hboot, bad motherboard, etc.) since you at least get the phone charging graphic. I suspect the phone will boot (at least to the bootloader screen) as long as it has sufficient charge. Bad batter is another possibility. But seeing as replacing the battery costs money, and involves taking the phone apart; let's eliminate other possibilities first.
