It seems my power adaptor has died..
I have been using it daily with no problem, and charged it over night last night.
I got a new stand today and moved the power supply to a new location, shifting the transformer with the adaptor still plugged in.
From that point on, no charging...
the cable is good cos it still shows up on the PC, although I guess it could be partially broken.
I have tried leaving the power adaptor unplugged for an hour or so, but no luck.
Anyone else have suggestions?
Is it possible that you bent a pin in the slot on the pad that you plug the charger into? Alternatively, you could take apart and reseat the 2 pieces
of the charger itself.
Pins in the pad seem fine, same on the charger.
I just turned it off to see if I could get it to charge from a USB hub on my PC, but it seems not.
This points to the cable being at fault, but with no replacements available I am still stuck with a discharging tablet.
Very Frustrating... I guess I will be Calling Asus support on Monday.
Its a shame Comet is out of stock locally, or I would walk into store for an exchange

charging thru a PC usb hub is slow...the ac adapter is rated at 15v 1.2a...and a PC hub is only 5v .5a i think...
Anyone know what the adapters for the other tablets are rated at?

I realise its slow, but I would expect SOMETHING after leaving the TF plugged in for almost an hour turned off!
This might sound ridiculous but unplug the usb cable from the power brick, unplug the power brick from the wall, set them aside....then wait a while (20+ minutes), then come back to it and try to plug it back in.
I had this same exact problem but I did the steps I told you and it began charging again. I'm not sure how or why though.

Plugging in the PSU normally turns the tablet on, and currently it isnt doing that.

What is your battery percentage at? Anything above 90, and it won't charge until it drops below. Kind of a built in failsafe.

Ah yes, it is above 90%, but I am sure it would show the charging icon?
I can only hope this is a false alarm, I will be less annoyed then..
Nope, won't show the charging icon. What I've done, if you want to ease the paranoia, lol, is hold the power button down and keep holding until the device shuts off completely. (do this with the plug disconnected) .. Now, plug the charger back in to the device. The device should power on, and you should boot up to a charging icon.
If it doesn't start up, then yeah, you may have a faulty charger. Let me know how it goes.

Then just let it run down passed 90% (like 88-89%) and see if it charges. If not, then yeah, sorry.

Little tip for you all... don't leave it charging overnight. It may be a bit late advice for some, but for others it might help them ending up with a useless power adapter. Unplug it when it gets to 100%. Get an app that alerts you with a sound, signaling when the battery is full. Battery monitor widget does this. Also unplug it soon after its done charging. This is assuming you don't care about battery life of course.
If you DO care about it then charging it up to 100% all the time isn't a good way to keep your battery healthy in the first place. Loads of guides on the web for Lithium Ion battery care.
There's obviously a problem with the adapter design, due to the amount of threads talking about this very issue, when people leave them charging all night. Maybe they are overheating, or some other reason. Prevention is better than cure.

Yeah I agree it shouldnt happen. Just saying I think it is. Pretty sure there are guidelines and safety features that are applied to all power supplies to make them safe for use in the home, at least there are in the EU, and it seems these ones are in violation of those guidelines, even though they have the CE approved label. If you are smelling something burning/melting its obviously faulty and needs to be replaced.
Well I tried comet for the warrenty and was directed to the asus support line, which is closed today.
How dull.

Is using the Desire charger just as slow at using a normal (5V) USB hub?
I'm no engineer but aren't there safeguards built into a charger/battery that is operating normally? ie: put TF on charger overnight, battery draws power till full then stops charging?
I use my TF all day, at night it goes on the charger, at no time does my charger get "hot" to the touch.

So last night before I went to sleep, my NT had about 40% battery life left in it. I'm currently running the final alpha build of CM7. I've been experiencing really bad wifi loss issues and have kept the 'Never' option enabled under the wifi sleep policy (thinking that would help hold the connection).
I woke up to find the NT was turned off. Figured that was odd as I was only asleep for about 5hrs. I turned it on and then noticed it got into the OS and then died. I did see the battery icon was red briefly.
I then plugged it into the wall and it was boot looping. I saw the 'n' logo pop up, screen went black, 'n' logo, etc. etc.
After numerous attempts of holding down the power button for 20+ seconds, holding power+vol down for 10 seconds, plugging it with or without an sd card into the wall and computer, nothing is happening.
The computer does see something as I'm hearing the common connected/disconnected tone from the USB port. Now I'm noticing that plugged into the wall, the 'n' on the cable stays orange. It never turns green.
Did it go 'poof' in the night somehow?
[EDIT] Ok after leaving it plugged into the wall for about 15mins, it suddenly turned on but had a google framework FC error. Yeah, not sure what I should do at this point. It appears to be charging...
It's been noted by others that if the power level goes below 15% you mustn't turn the device off if you don't have the original charger nearby. If it dies you need to charge it with the original charger for a bit before it'll power back up.
I assume this means that you can't run it off the cable while you've got a completely dead battery. That kind of stinks but isn't too surprising, a lot of devices are like that.
So does that mean that if the device is <40% of battery I need to plug it in if I won't be around it for a while? Not sure I'm cool with that. Battery life was great all day yesterday but somehow it dropped 40% in under 5hrs while asleep.
I can't really say much as I haven't dealt with it personally. People were talking about it in a couple threads about the NT's charger and unique 12 pin cable.
Here's what I understand from what I've read:
You can run it until it's empty all you like. You'll just need to use the Nook's factory charger (or a compatible 2A charger with bridged D- and D+ pins) AND (this is the important one) the factory USB cable to charge it.
If you run it until it dies you have to charge it for a little while before it'll turn on again, BUT you have to use the original cord and charger. It won't charge off of a regular micro USB cable nor will it work if you're using a 2A or smaller charger that doesn't have the middle two pins bridges (the Apple UBS chargers won't work nor will your PC's USB ports, for example).
The NT will charge, albeit slowly, if connected with a third party cable or USB charger (without the data lines D- and D+ bridged), but not if the device's power has been depleted.
So I suspect something sucked up a lot of juice while you weren't using your NT. Not a huge deal, but definitely annoying. Plug it in for 15 minutes and you can get rolling again.... BUT only if you're using the original charger and cable. Lovely isn't it? It's not a huge problem but it is annoying. I wish you could at least use the device with a dead battery while plugged in.
I just mention the charger/stock cable thing because I'm sure someone will probably see this post in the future and may be having that particular problem resuscitating their NT.
Cool, yeah I don't specifically set out to run it down to zero but since the device is clean with minimal stuff running in the background, it's difficult to know when this might happen again. I assumed I'd wake up with like 20-25% battery left. The framework FC is also something I'm concerned about but maybe it was just a fluke.
Ah well, really do appreciate your input and I'll be sure to keep the stock cable/adapter on hand when I'm on the go.
Battery showed fully charged, I rebooted to do another CWM backup and then when it came back up it showed 84% charged. Lol. And this pic made me laugh even more. Time to get that lady from Poltergeist involved I think...
The Google Framework force close is typical of stock rooted NTs. I don't believe it ever did any harm to anything though. Just that it sometimes appears on reboot.
I'll ask one additional question as to not make another topic since it's related.
Opinions on battery calibration with the NT? That was one of the reasons I didn't charge it last night as I wanted to fully run it down and then fully charge it back up. Does the NT require this with a new rom install? That pic above shows the battery gauge clearly wasn't correct initially.
Your battery is draining overnight because wifi is running the whole time (as you stated in your first post).

That's what I obviously thought of at first but it didn't drain nearly as much when I was using it throughout the day. The only thing I can think of is maybe the fuel gauge itself was wrong from the start, which refers back to my calibration question.
My GS2 has the sleep policy set to 'Never' as well and only loses maybe 7-8% after being asleep for around 7-8hrs and it certainly uses more juice in sleep due to the cell communication, etc.
I just got my new Prime in today and it is completely dead. Plugging it in via the wall charger or USB in my computer, I do not get any charge lights. From what I have read, the wall charger can have some issues and it may take several hours for the unit to charge enough to turn on, but I do not get any charge lights. When plugged into my PC through USB, I dont get any new devices in device manager.
Are there any tricks or resets that I have missed? I will leave it on the charger, but it looks like I am going to have to return it for another one
This happened to me yesterday. I had left it on while out of town, got home and it was dead. I plugged it in and no lights, no sound, no nothing. Left it plugged in for about 10 minutes and then went back to try. Held down power button for about 20 seconds, nothing. Tried holding it down again for about 20 seconds, nothing, and then when I released the power button it vibrated and powered up. Don't know if this helps, hope it does.
Try the paperclip into the reset hole below the micro-sd card slot.
Try putting the power adapter in a baggie and throw it in the freeze for a little while. This is been posted before and got me going again after mine did the same thing. I had always left my adapter plugged into the wall and some seem to think it for whatever reason causes it to overheat or stop working.
Last thing. The Prime will not charge off of a PC using USB ever. Only 5vdc from USB and it takes like 12-15 volts to charge the Prime.
Good luck,

That is incorrect. It will charge, when turned COMPLETELY OFF from 5v, although it is at a VERY slow rate. 15 volts is required for full speed charging.

I stand corrected then. I did not know that. Thanks for the heads up!

The freezer trick is for if the charger seems to be overheating.... If you notice it gets very hot then thats a quick way to cool it down (happens from time to time)
You can also try ipad chargers, they should be able to put out the 12-15 volts the prime uses to charge, or you can build a custom charger, theres a few threads on XDA about it
It will take roughly three times longer to charge via the computer with the prime OFF, with the prime on its using about as much power as its getting so having it plugged in to the computer will do basically nothing.
Hopefully this helps

Look at your charger brick. The plug end can slide off of the brick part. I've had mine slide slightly and you couldn't tell that there was not good contact between the transformer part and the plug part and it would not charge. I thought, oh good, my charger is dead then I realized what was going on. Snapped it back it place charged fine.
yep, gotta put some force towards sliding it in until it clicks

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...

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.

Ever since sometime yesterday or something. My phone has been steadily discharging whilst plugged in.
I charged my phone to full yesterday and noticed that it was charging a bit slowly.. but eventually it got there.
Then I unplugged it and plugged in a really low battery (4%) to charge it to full overnight (I have 2 batteries)
I woke up to the phone at 26% after an entire night of charging (about 8 hours).
I thought that the battery must be dead. It's a cheap one from Ebay but it has the official sticker on it, but it's a bit creased so it looks like it could be a cheaper one with a fake sticker on it. It always used to last about 20% less than the original one I got with the phone anyway. But that isn't the point.
I thought it must be dead. But I charged it a little before work and nope, it just kept dying. So I started worrying if the charger had died.
Then I just swapped the battery out and decided to use the fully charged one.
After about a days use I went to plug it in and it ALSO started discharging whilst being plugged in.
In fact they seem to discharge FASTER if plugged in.
I immediately thought that the little Wall Socket to USB Adapter had just blown. So I unplugged it and just plugged the phone in via my PC's USB 2.0 Port.. Same thing.. it sits on the same Percentage (%) and then gradually (if I use it at all) it starts to discharge.
It's charging so slowly that if I use it at the same time it'll die. When before I could even have a Skype call and keep it plugged in and it would overcharge through the amount of power I was using.
Does anyone have any ideas? It can't be the battery because both of them are dying no matter one, and they can't have both died. It might not be the little USB charger (although it no longer gets hot like it used to) because if I plug the phone straight into a USB port on my PC (I know the mW is lower but it should still prove if the charger is dead or not) then it still discharges.
Any ideas? I mean... it looks like somehow the USB port is no longer taking a charge? Without my phone I am a dead man.. it will totally mess up my work and everything...
Have you used a different cable? You said you plugged it into your PC USB port but you didn't say with which cable.
I don't have another cable :/ as it's a proprietary one... I can't just use some normal micro USB..
9/10 it's the cable that's the fault.
It's not proprietary. I walked into a shop and said "2 micro USB cables please" and they both work better. Also my HTC and blackberry micro USB cables both work better. Try another cable. Borrow one if you have to

I have a micro USB cable.. it's for my HDD and it doesn't fit. It's a little bit too big. The last HDD I had too was the same, just a bit too big. Maybe it's not proprietary but I'm pretty sure it's smaller than the traditional Micro USB.
Also, I tried doing a file copy from the phone to my PC and back and forth. The speed is totally fine, really fast.
So could it still really be the phone? I'm a pessimist and I don't see why the cable would just suddenly die... I've already had my phone replaced on one of the 'sudden death' issues like everyone else. I wouldn't be surprised if there's yet another hardware fault...
At the moment it's off, and charging from the wall.
EDIT: Maybe it's a Mini-USB not a Micro.. in that case I have 1 Micro USB. Still I think my phone just died somehow overnight................. again.

what? yes you can
Well cables are expensive in Finland but I suppose I have no choice but to bike down into town and buy another cable...
Most hdd caddies are indeed mini

no, your phone uses a traditional micro USB. and data speed is not really connected to charging speed
New cord seems to have fixed it. 'Hama' brand (Finnish) triple shielded, with some gold plated connectors. Looks a lot higher quality than the traditional Samsung one. (Unshielded, no gold plating)
Also it's a bit longer, which I dunno if that will affect the rate of current. I know that shorter is better. It's 1.8m vs the older 1m.
Seems to be charging properly now, still a bit slow (phone is off) but I suppose that could just be the battery getting used to actually receiving a proper current finally.
Christ and I almost went and just bought an iPhone...
If in the end it was just the cord then €12.95 bought me peace of mind.
EDIT: Scratch that
It won't charge if the phone is on at the same time... it just sits at the same level of power. But if I use it, yeah it starts to discharge.
So basically it's lost the ability to charge whilst being used, and on top of that it did charge pretty slowly when turned off, but at least it did.
Looks like I'm going to have to sort out a way to fix it, then maybe sell it and get something else. I can't handle a phone that's such a disappointment.
The Galaxy S2 was a bit of a let down, to RMAs to Samsung now...

Shame that it doesn't seem to have done the trick.
I'm really confused now. The battery I got off the net doesn't seem to be charging really at all, but ever so slowly when the phone is off.
The other battery, my normal OEM one charged sorta slowly but kinda normally I guess..
Really don't know what on earth is going on. It's going to be a total pain to get this thing repaired a second time, and it's been rooted and flashed multiple times. Plus it has the new bootloader on it that you can't possibly trick that it's been rooted.. (was installed after a fix on warranty)
So the oem battery charges normally?

of course you can, use TA
You may have a faulty charging port (if not battery problem)
Why not download the Galaxy Charging Current app and see if your SIII is charging at 1000mA using wall charger?

BTW - Other than faulty charge cable, it could also be faulty wall charger

Thanks so much for the app. I bought the pro seeing as it's only 0.50c
Now this is really confusing. I'm gonna do some testing now:
On the cheaper battery Ebay Battery Using New 1.8m Shielded Cable With the OEM Wall Charger
If I plug the cord straight in from the wall charger without moving it the power starts off at 1000, then goes down to about 900, then after awhile to about 400, and then after awhile longer to 100. But I can't be sure that I am not bumping the cord even a tiny bit. Also the battery is at 94% so it could just be shutting off the charge in order to not overcharge. (Though before the issue the batteries always charged to 100%).
If I move the cord around and tap refresh the number drops by 100 - 200 every time I press refresh (all the way down to 100). Also if I move the cord perfectly back into the middle, the number doesn't go back up. It's like the more I move the cord around the lower the charge will be. If I leave the phone alone for a bit and look at it again after a minute, the rate has gone back up to 1000, then down to 900. Where it seems to stay.
The statusbar battery app shows that it is charging too (% is going up as normal)
At 97% charged on the cheap battery the phone only accepts a maximum current of 300. So it seems that the overcharge protection is working.
Though the battery can display fully charged and then drop to 97% after I unplug the cord. Which didn't happen before but it's an understandable thing.
Summery:
Moving the cord a lot causes the rate to drop dramatically.
When plugged in the current starts off at a full 1000, then drops to 900 (dunno if this is normal) so it seems to start off charging at max
The max concurrent, current that can be achieved from the wall charger with new shielded cable is 900-100 it seems.
The phone seems to discharge faster when plugged in (and current on 100) than when it's unplugged??!
Could someone please install the free app (Galaxy Charging Current), who isn't experiencing issues like me and wiggle their cord around and see if the rate drops too? I want to know if there's some sort of methodology that if the cord is moved around a lot the current rate is dropped, and it won't return to normal. Or if it's just my phone. Thanks so much!
====================================================================
Ok... tested with everything I could honestly think of. Ebay/OEM Battery, Both OEM/New Cord and USB/Wall chargers and etc,
Basically it's like this. Both cords are fine. Both charge the phone just as fast. Using the wall charger is faster than using a USB. (But not if the cord has wiggled so much that the rate has dropped lower than what as USB gives)
The current rate only drops when the cord is moved, and here is the crucial thing:
When the cord is moved the rate drops anywhere from 100 all the way to 900. Meaning that the rate of charge can go from 1000 (max) down to 100 (absolutely nothing). Either in 1 go, or in bits every time the cord moves. Also if the cord moves EVEN ONCE, even the smallest bit the rate can just drop on its own.
So basically it seems that somehow there charging port has been damaged or something and the pins are no longer connecting and the phone or charger or SOMETHING has this incredibly bloody stupid thing where if the cord moves or if the rate drops, it doesn't go back up. So if the rate drops all the way to 100, it won't increase or go back to normal after a certain amount of time.
Or maybe I am wrong.. because if I push the cord even a little towards the back of the phone the charging light goes off completely, and the rate hits 0. Whereas if I pull it towards the front of the phone, the rate stays constant (at max) but if I take my hand off it, the rate drops to about halfway or really low. It just seems like the little connectors inside the phone are really.. really flimsy and loose. It obviously got damaged somehow. Either by constant connecting and disconnecting or bending or just you name it.
So does anyone have any suggestions? I might try and clean the inside of it with nail polish remover or something in case they're just dirty but I doubt it will do much. It seems definitely like the plug just doesn't fit in and connect well enough any more and that's where the power is being lost. It's gotten a bit loose, but really nothing out of the ordinary.
I can confirm that putting it in such a position where there is absolutely no chance for the cord to move at all, allows the phone to receive a constant rate of the highest possible charge.
I guess I could try and make the fit a bit more snug myself but it would be only really temporary.
I think I just need to get it serviced again, but I am not sure that I could because it's got a custom rom, it's rooted and it's already been repaired for one of those 'sudden death' issues already...
How generous is Samsung with their warranties?
Either way this is a terrible blow for me, I need my phone to pay my bills and stay connected with my work and friends. If I can't have it plugged in and still be able to move it around and use it. Then it's basically useless.
At least for now it seems to be charging okay just sitting completely still on the table.

I am having the same issue as you, I have been managing to get it charged using my ipad charger which is stronger but it sometimes still doesn't charge with that. Last night I put it on charge and it turned off due to dead battery in the middle of the night. Did you manage to fix this?

Since no one replied with a solution I will let you know my fix. I sent it to Samsung for repair under warranty and they have fixed the issue. It is due back tomorrow. Just so anyone else having this issue knows its covered under warranty.
I've got the same issue. At first i thought it was the custom ROM acting up. But even after unrooting it and going back to the stock firmware its still the same. The only way i can charge my phone is by switching it off nd plugging it in. Cuz no matter what i try, if the phone is switched on,the battery still drains. Couple of my friends had the same issue too.They ended up buying new phones. Guess this is a standard fault with all Samsung phones. If anyone's got a fix,do pass it on.

I´m having the same problem. I flashed my S3 i9300 to a cianogenmod 11 ROM. It's a relief to know it's not the ROM. The technical service prom the phone companies here really suck, so i'm taking my S3 to a third party cellphone technician and tell you if he solved my problem.
try this.
dear poster I have a solution that may work for you ,first thing take the battery out of the phone and leaving the battery out plug the charger in .leave it that way for about an hour .then unplug phone pop battery in turn the phone on .the replug the charger while the phone is still on and see if it charges better .
Ok, so I've crawled everywhere for the last few days to try and see if anybody else has had this issue, but alas, nobody has.
So my device was purchased in Nov 2013, out of warrany. No luck there with a replacement.
Last week I was watching a show, low battery, it powered down. No biggie, just plug it in and let it charge. But it refused to do anything at all, even after charging for 24 hours. No power, no screen, nothing. Held the power button. Nothing. No noise, no lights, nothing.
Contacted Tech Support and they sent me one of their 9w chargers and said to try that. Got it, plugged it in overnight, again, nothing. Held the power button for 40 seconds, nothing. Tried it while plugged in, nothing.
Contacted Tech Support again and they said nothing they can do other than offer me $20 off a new device. No thanks.
I plugged the unit into my desktop and it blooped that a new device was connected, and in the device manager I have the "QHSUSB_BULK" device. This is a totally stock, nothing new, not even developer options enabled (when it had power)
Is there anything to be done with the device at this point?
Again, no power, no screen, no lights, nothing.
Unresponsive.
Help?

Probably not, sorry.
There is a reason why Android in general pops up request about battery charging 2 times before it shutdown itself. One is about ideal state for charging modern Li-ion battery , which is around 10 - 15 % its capacity, second is about a minimal safe level for Li-ion battery, which is cca 5%, and under this (believe or not) some bad things can happen, including internal storage media corruption while writing something and not enough juice left in the process of shutdown for finishing it...
I don't know for real what happened in your case, but I have seen this type of posts about android shutdown because of no juice left in battery and after charging device was dead in other forums for some other devices...
My first tablet was Asus Transformer tf101, which had extra battery in the keyboard, and manual clearly stated, that its capacity must not drop under 3%, otherwise it can't be recharged properly and must be replaced...
So IMO people risks every time when they ignore this request for charging battery, and I must admit I too let my Apollo shutdown 2 times in last 2 weeks because I was too lazy to connect it to charger... but after this post I will definitely rethink next time...

Sounds like you have done your homework. Unfortunately, gut tells me you have a defective hw component. Could be the battery, regulator or some other power circuit. If you have a USB3 port (and cable) try plugging into that for awhile. It might just put enough charge on the battery to permit some type of response combined with the higher power output of a USB3 port. In my experience a USB2 port does not provide enough juice to power high draw devices with a crippled battery. It's a long shot a best but if you can get a response and diagnostics confirm it's the battery you could consider replacing that (no easy task) to recover your device.
Another option is to snag an inexpensive USB current meter (examples here and here) to see if the device is actually drawing power while on charge. If the reading is close to zero you likely have a charge circuit problem which can't be easily remedied. A bad battery would still draw some current...just wouldn't hold a charge. Note these gizmos can also be used to identify a bad cable, bad charger or combination of the two for virtually any USB device. You'd be amazed how many crappy cables are out there that severely restrict charge rates. But that's another matter ...
Sorry I couldn't provide a more optimistic response.
So maybe try replacing the battery?
ifixit says they're kinda hard to replace, but for $50 off Amazon it might be worth it vs the $150 they quoted me for a replacement tablet.
I've had a few devices shut down on me like this (I try my hardest not to, but we all fail sometimes) and I've just never run into this issue before.

Thanks for the reply. Like I said above, I charged it with their charger, 3 of my own, my USB 3.0 port on my desktop, all with multiple cords. So no luck there. I've kind of been figured it's just EOL for this thing unfortunately and I just don't think I'm gonna bother with it at this point. USB on the desktop recognizes it, but nothing further.
Time to mount it on the wall I guess lol. Thanks for all the responses and confirming what I suspected, it helps to know that others think that my conclusion wasn't premature.
