Gtab won't turn back on after going into sleep mode on TNT lite. Can anyone help me get this tablet back on? Is there a hard reset button somewhere?

There is a reset button, but you have to crack open the device to get to it. I'm serious. This is a known issue with stock (and I assume TnT Lite 1.x is also affected, going on what you've written) - I've had this happen myself and I've called CS about this, already.
imo, you have three options:
1- Wait for the battery to die and it might "fix itself" (stress the "might" part). The device is definitely on, in this sleep mode that you can't get out of. I know this because when it happened to me, the device was recognized as a USB device when I connected it to my system and ran "lsusb" (Ubuntu). Second, when I first cracked my device open, I could see a green light inside so that told me it was actually on and drawing power.
2- Crack it open and hit the reset button in the middle of the board - this will most likely fix it immediately, but as you may expect it will void your warranty. There are four screws behind the rubber feet that you have to take off, and a bunch of clamps around the device that you'd need to pry open with something like an iPod plastic prying tool. It's a bit of a PITA to open and you have to be careful.
3- Return it / exchange it. Of course, all your data is there so hopefully there's nothing you care about or stuff that's confidential.
EDIT: The battery should drain completely within 24 hours. Once that happens, you can use the power button again to start it up and then you'd want to connect to AC to recharge, of course.

Hey, all.
What does the internal reset button actually do? I was expecting it to reset to factory settings, but fortunately for me it didn't do this. I'm actually happy it didn't, as it means I didn't lose any of the customizations I had done or applications I had installed.
I just cracked open the case on my gTablet and pressed what I assumed to be the reset button, a tiny little white switch in the center of the unit. After pressing and holding it for about 3 seconds, the tablet immediately powered back on and returned to its previous state. Everything appears to be functioning perfectly normally and exactly as it was before.
What does the reset button actually do? Do I need to worry about battery meter not being accurate or any other weird side effects? I only mention that because the battery gauge is showing 100%, but the external red charge light is still on.
I'm not sure what prompted it, but earlier today, my gTablet went blank and wouldn't turn back on at all. My son had been playing Angry Birds for an hour or so and I had been using it heavily showing it off to my in-laws, so I thought perhaps the battery had simply gone dead. I had not plugged in the charger the night before, so it seemed to be a reasonable explanation.
I plugged the charger in and the external red light was visible, so I let it charge for a little while, then tried turning back on. I could press any number of different key combinations (power & vol+, power & vol-, holding button for long time followed by short press, etc.) but I got nothing but a black screen. There was no indication whatsoever that anything was happening.
I was assuming something had gone quite awry, but didn't panic. My wife was not quite so calm, but I reassured her that I would be able to find the answer on the XDA forums. Thanks to everyone who has contributed to this great community, by the way!
First, I tried plugging in the USB cable to my Windows 7 laptop and heard the distinctive 'bing-bing,' notifying me that hardware was recognized, so I knew it wasn't dead. But, it didn't show up anywhere, so I checked the Device Manager. Interestingly, there was no yellow exclamation mark anywhere, as I expected from reading some other posts about NVFlash. I finally found it listed under the 'Disk Drives' section as: 'NVIDIA Tegra 2 USB Device.'
I remembered reading about people experiencing problems with the unit going into APX mode, but I also remembered reading about the internal reset button on the gTablet. So, I figured before I attempted to use NVFlash, I would try the reset button first. Fortunately, these devices were designed well and the case was very easy to pop off.
By the way, I was running the stock ROM, but with the TNT 3588 Enhancement Pack (Gapps with nVidia Drivers) provided by edirector. I had also installed the z4root application. I used the default ROM for the first day, but was comfortable with the idea of flashing othe ROMs, as I've done it with my HTC Aria phone. I flashed roebeet's TNT Lite 4.40 and used that for several days before going back to the factory ROM with the enhancement pack.
Thanks in advance,
Calvin
Well,
I've been reading these forums since last November and I don't know of anyone who
has really reported on "pushing" the reset button before!!!
Usually when people crack the case to push the reset button or unplug the battery
for 10-15 seconds it is a situation where they can't get the machine to start and
literally have nothing to loose.
Sounds to me (in terms of 30+ year of different computers) that you did a hardware
reset and boot. I assume something was locked up inside and the reset key released
it to restart.
Glad for you!!!

Last night I was using the tablet as normal. I sat it on the pillow next to me to grab my TV remote and I saw a pop-up on the screen out of the cornerbofbmy eye ,which was out of place. There was no reason for any kind of pop up.
This wasn't a notification. It was a pop-up window right in the center of the screen. The same place where the the window appears when you hold power down and you get the menu of Power, Restart, etc…
And in fact, all I saw of this pop-up was "… .. is turning off" and then it did.
But, it immediately came back on and the Android logo appeared like always then TWRP recovery screen flashed for a second and it went off. I have not been able to get it on since.
I have held the power button in for 30 seconds and I have tapped the power button. I have done every combination of power buttons with volume button and then repeated those with it plugged into the pc.
I just removed the back of the tablet and the battery out reading spot on. I'm confident that the battery is not the issue.
Now I'm lost on where I go from here. Is there a method to bypass everything and fire up the screen to see if that works?
I'm open to anything.
Any help would be life saving.

It sounds to me like you got the ota that killed your tablet. Is it the original shield tablet? You should check the serial to see if it was recalled. I don't know the address but just Google Nvidia recall battery, you'll find it

Yes, it is an older tablet compared to the newer "K1 no stylus" version however, when checking the battery number it said it was a B01.
The idea ilof getting the kill switch never occured to me as a possibility due mostly to the above mentoned not being a candidate but also because i didnt realize the kill switch completely shut it off and somehow render the power switch useless.
I was thinking it caused a bootloop or something like that. My tablet has zero signs of life.
I will have to approach Nvidia tomorrow and hopefully get this somehow sorted out.
If this was in some way my fault and I misread the battery info i still shouldnt have recieved the kill switch because I never activated a replacement. Correct?
Is this is somehow reversible? I imagine its not since I can't power the damn thing on. I have 3 other Shield Tablets in the house. 2 OG tablets and 2 new K1s. If there was a method to use a working tablet to resuscitate my dead one, that'd be interesting.
I'm getting ahead of myself tho. I feel this is an Nvidia error and should be taken care of by them.
Word if caution there's guys going around on craigslist emailing about shield tablets that are for sale asking for serial number to verify warranty..only to submit a claim for the recall tablet .. Happened to my brother..
Hey everyone who reads this.
I'd like to start my topic with apologising if I post this in the wrong section.
So, I have a LG Spirit H440N LTE for about 3 years now, maybe a little less. I've always taken good care of it, both physically and in updates / security wise aswell.
My phone has been working flawlessly until the last 2 days. 2 days ago i was charging my phone, and when it vibrated (meaning its 100%) I pulled the cable off, and pressed the power button (power button locks - unlocks the screen) the screen didn't turn on. I was like "wow that's strange" but didn't care much, i just kept pressing the button every 5-6 seconds, nothing.
At that point I pulled the battery out, let it sit for a short time and then put it back, start the phone, I felt the vibration (meaning it's starting up) but no screen, so my first idea was that I need to get a new firmware and completely reinstall my phone, as it seems like it got bricked.. for no reason, by itself ? Strange thing but I accepted it and literally been googling for 9 hours now and I find more and more issues.
After I got LG FlashTool, drivers, and even 3 different firmwares, I wanted to start the phone in download mode to start upgrading, but even though I held down "volume up for 5 seconds and then put the usb cable in" nothing happened, no screen, my PC didn't recognise the phone either.
So I got a little bit mad and pulled the cable out from the phone, I wanted to remove the battery, but out of nowhere the phone suddenly started loading in, screen working completely fine, i could do whatever i want, so my first thing was to do a hard reset. After the hard reset I set up my usual stuff (important apps etc) and I locked the screen so my battery won't go down. Little did I know, I ****ed up again, because ever since that happened, I can't get my screen to work again. I tried everything I could but my PC still doesn't recognise the phone (even after a LOT of drivers being installed), charging the phone doesn't do anything. Regardless if I remove - put back the battery no screen, no screen in download - hard reset mode either, it's just completely black.
I'd like to have some sort of help, because I am just completely out of ideas, I really feel like a firmware change could fix the phone, but if the computer doesn't recognise it, I have no idea what to do.

You might be having hardware issues, such as a faulty power button. If you are the type of user that frequently presses the power button to lock/unlock the screen, this leads to excessive wear on the button components, this is why some users prefer to use the "tap to sleep" and "tap to wake" feature, to avoid wearing the power button out. On my LG, this feature is called "KnockOn", it's located in Accessibility settings.

So my Note 10+ screen broke so that I can only see the top 15% and only touch the bottom 60%. I booted into TWRP to backup everything, and now I'm in a situation where I can't turn the thing off. I am unable to press the shutdown button, only the download mode and recovery mode buttons. I am also unable to press the ADB side load button to send a shutdown command. It will be quite some time before I am able to fix the screen, so I don't want the phone battery to be sitting dead and degrading for a month or more. I already tried draining the battery and then plugging it in to charge, but the phone automatically booted into TWRP.... hardware key combos only reboot, they won't shut down...
Does anybody have an idea how to power off my device? Or to reboot into system or gain ADB access without being able to use the touchscreen? Thanks for the help
Humm, after reading the "how do we make XDA a better place thread", and the "this place is just not as good as it use to be" thread, I thought I would try to help. But I suppose that if you were on the forum since 2010 you have probably already thought of this. Also, I don't have a "Note 10+", so this is just guessing based on general Android behavior.
My screen is also unresponsive and I was able to reboot/power off by just by holding down the power button for half-a-minute. Sometimes I would have to "pull the battery", as soon as the phone started to reboot. I've done it a few times and haven't bricked the phone yet. So it is not something you do not want to do all the time. But then again this response will probably not be helpful because your phone does not have a removable battery. (whether or not a battery is pull-able is not something generally listed in the phone specks unless you do lots of digging).

Yeah unfortunately battery is sealed inside and holding the power button yields no result
@TheLexx
Take phone to authorized service center and let them fix it.
The problem I have is with the galaxy z flip 3, it worked just fine inthe morning but after it ran outta juice and I charged it to a certain percentage, it stopped working properly, and got into an infinite boot loop, I tried forcing it to restart by long pressing volume down+power , but it didn't work, then I tried opening the recovery by long pressing on volume up+power and yet it also didn't work (I think that maybe it's because it was trying to boot at the time), so have you guys any solutions , please do help me cuz this phone really is important and with all honestly, isn't even mine XD, I'll be waiting for an answer
Your failsafe options are contact Samsung or do a factory reset (and then potentially contact Samsung).
If you can't boot it to anything, the only real option you have is to flash firmware, which likely won't help without wiping.
Unfortunately, not booting doesn't have a whole lot of options that don't wipe data without being rooted. Even then, you'd need recovery.
I see, then I may consider giving it to samsung, as long as they won't reset it, cuz the only reason why the phone is so important is because of the data, altough, isn't there any other way to acess recovery? Cuz I had this problem with the s10 before and I fixed it somehow (a certain Bixby key combination), but this time it seems there isn't any hidden combination.
Samsung is going to reset it. It's a required first step for them to do any work on it, even if the work has nothing to do with the software. What may help find a way to recover the data is starting with how it got to this point. Did you install anything new, change any important settings, or anything else that could have been a part of the issue? If not and it is an unexplained hardware failure, the data is likely gone already.
If it's something you might have installed or changed, it's possible that putting the phone in safe mode and undoing it may solve the issue and let you boot normally.
Booting into Safe Mode:
Make sure the device is powered off (charging is ok, as long as it is not currently trying to boot)
Hold the side key to power on and continue holding until "SAMSUNG" appears and the device vibrates
Immediately release the side key and begin holding volume down until boot completes
If the device has booted into safe mode, you will see a translucent "Safe Mode" in the bottom left

Well I just asked the original owner (my mother), and apparently she doesn't remember downloading anything new into it, and it just went crazy by itself, also something else I wanna note, I tried charging it and it booted into recovery all by itself, I taught it was weird but Still went and wiped the cache and then when I tried restarting it it suddenly ran out of juice once again, also, it's second display shows some weird curruption/bug or glitch-like lines. So based off of this, can you really find the origin of this problem and if there is really any hope of saving it's data XD. Thank you btw, and once again, I'll be waiting for an answer
There are hundreds of reasons it could do that, including a faulty board. Thanks to the removal of physical sdcard support, you'd need to get it to boot into something with at least adb support to pull anything off it. Stock recovery doesn't provide any ways to perform a decent backup, but it sounds like the only option that wouldn't wipe the device didn't work.
I see, alright, thanks a lot, I'll consider resetting it
It may be worth trying to flash firmware first. Go into it knowing it may reset the device or leave you needing to reset it, but it doesn't hurt to try if you run out of safer options.
Same here, same symptoms, happened in front of my wife's and eyes face. We are fairly techy and understand our way around our devices. We also noticed the device crashed then would make it all the way to the home screen launcher and before catching signal the crash would cause a restart at that point I went in and did a cash swipe rebooted right back into recovery by itself then I unplugged the cable and it was acting as if it has a dead battery but when the cable was last plugged in during a couple of crash and then restarts all the way to the home screen I know the battery was at 70 something percent. My next step is going to probably be flashed the current firmware that just released on top of it as a dirty flash and see if I can get it to boot. If not then I'm going to do a hard reset and see if that works. When plugged in it automatically starts exhibiting symptoms as if the buttons are stuck. The devices in the OtterBox and it's fairly brand new I would say mint. Not dirty or any smudges either. all I'm saying is I'm one of those type of technicians that say yeah right when people say it just happened I don't know where but this actually happened I don't know when I was able to witness it. I'll come back and let you guys know what works and what doesn't. (By the way excuse my grammar I was voice typing while driving )

Hello everyone just a quick update. Once I got home I plugged the device into a Samsung fast charger and Samsung OEM USB type-c cable and realize the device booted all the way to the home screen but register the same battery level as I mentioned above. Device was working as if nothing happened to it. So I updated all the apps on the Galaxy store then updated all the apps left over from the Google Play store, I then proceeded to check for a firmware update because I know the April update just released and installed the update with no issues. Updated the apps that needed to be updated again somehow there's always something and unplug the device from the power cable. Everything was working if no issues about half hour later the device cuts off and does not want to power on. FYI I already had my wife contact T-Mobile and get a warranty replacement we only paid $5.00 so my thoughts and conclusion on what's going on something happened to the battery or it's defective. Btw we only use Samsung OEM cables and equipment at home and in the car while connected through Android auto. it's only working while being plugged in it's not charging all the way even though it's registering it's charge level while the device is on.
