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.

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.

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.

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

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.

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.

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.

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.
I had the same problem
I had the same problem, what i did was, instead of charging it with the original charger, i charged it with my nexus 10 charger in download mode all through the night, and the next day it would have about 80 percent charge and it was in the system, but it drained quick when i would unplugged it, so i repeat the same procedure over several days until get to 100% and scince then i have had no problems with my SGP, hopefully i helped you

Anyone see a similar issue and know if the battery is likely to have failed or something more fundamental?

I've tried most chargers and I have a lot of them, including original chargers for Z3 and Z4. Even trickling on a slow charger should recharge after 24 hours but nothing.
Wish I'd remembered to keep it charged, can't even get a bootloader up.
Try this??
Press the volume up button and power button together for 10 seconds. This should cause your device to vibrate 3 times and then show the battery charging screen.
Nope, I've tried all of these already. Probably need to open it.
weird dude.as far I know,li-on batteries need to fully discharged once in 30 charges.I made it once (it closed from battery) but nothing weird happened to me.I am always on KK 4.4.4

Good news! Thanks to everyone here who convinced me to persevere and not sell this tablet as broken!
For 4 days I have been charging the tablet and trying power+vol button combinations a couple of times each day and finally, on day 4, I was able to first get a red led. After the led went out about 10 mins later I tried vol+power again and got the emergency battery graphic plus red led. Led went out after ten mins again and had to use vol+power. Seemed to go a bit strange at that point and charging halted. Swapped chargers and waited.
Next time was the trick, got red led, it went out and I was able to get the normal, smaller charging graphic. Let it get a couple of % for safety and hit power, resulting in a full boot. Tablet is booted at 4% and charging OK.
Thanks to everyone that helped out.

Exactly as per above, keep repeating the power & vol- sequence and putting on charger for a few hours. Exact brand of charger doesn't seems to matter, the one it worked on was a no-name two-socket UK plug charger from Amazon. Obviously a 2A+ charger will help. The cable used was a generic Samsung 1m (3ft) lead.
Just repeat the process and leave it on the charger in between. I'd recommend not charging a unit like this unattended in case the battery is damaged and there's a battery failure, I've seen a lipo fire and they're ugly.
Thanks dude!enjoy the best tablet! ?

Hello again xda members. If you guys know who I am you'll know I love Azpen Tablets bought from MicroCenter. A few years ago myself and others provided the community with a solution to "unbrick" the Azpen A727 and following I had mad a step by step tutorial on how to get the A727 working again.
For about 6 months I have had trouble with my Azpen A1023 10inch Tablet I bought from Microcenter a few years back on sale for 60 bucks. The issue with it is it will not charge at all, it wont even turn on when I have it plugged in to a USB charger. Ive tried multiple things. Holding down the power button for 30 seconds to do what i heard is a power cycle, holding down the power button and the home button for 30 seconds, trying different USB wall chargers with 500ma 800ma, and 2A. And it absolutely does nothing.
Now I am assuming it is a completely depleted battery since I left it unused for a few months since I realized I had this problem. I went from the A1023 working fine to not using it for a few months and it not coming on or charging at all. Now I heard if you leave a tablet that has a completely dead battery (in which all its cells are depleted, not your battery dying) and you plus it into a USB port that has low milliamps (ex. Computer USB 2.0 port (500ma)) overnight or for a day then the low trickle of power for a long period of time should bring the battery back to life. I am actually trying that method right now as we speak. Im going to attempt to bring my tablet battery back to life by leaving it plugged in my computers USB 2.0 for at least 24 hours. Also I heard of unplugging the battery from inside a tablet and replugging it back in sometimes helps this problem, but when I opened my Azpen A1023 up I come to find that the battery is soldered to the mainboard with some wire. Worse comes to worse I'll snip the wires and re-solder them, tell me what you guys think.
I'll let you know how it goes!
P.S. If I need to be corrected for something I said (ex. calling it a "depleted" battery) feel free to correct me because when I do threads on any site I try to be as professional and direct and legitimate as possible. Also to let you guys know, any help and any solution that is found or steps to a solution you will be credited for you help when I edit this post for a final tutorial on how to fix it.
So I had my Azpen A1023 plugged into my desktop computers USB 2.0 port at 500mA I believe for 36hours and still its not turning on. Ill leave it plugged in for a week to see what happens. And of course the PC is on and I shut off advanced power setting of selective USB power or whatever its called. Anyone have any input?
So I decided to open up the A1023. I unsoldered the battery from the motherboard left it for 20min and resoldered it back to the mobo to see if that helped . still nothing, wont charge or turn on. Any ideas?
Azpen tablet not charging.
Did u ever get it charging. If u did how
I've had the S23 Ultra (US, unlocked, from samsung.com) for a couple of months. I didn't root it, drop it, or splash it with water. I charged it last night, but when I woke up this morning, there was no sign of life: a black screen, no sound, no reaction to charging (even after long charging with a different charger and the cable), no reaction to a long press of Power + Vol Up/Down, and nothing detected in adb.
So I have a few questions:
Has anyone else had a similar experience with their device?
Any suggestions on how I could resurrect it?
Do you have any ideas about what might happen? Throughout the two months, I used the same old low-current (850 mA) Motorolla charger. The charger is still operational.
My current plan is to contact Samsung Support.
Any advice is appreciated! Thank you!
Have you tried using a higher capacity charger, like an official Samsung charger plugged into the wall? Have you tried a wireless charging pad to rule out an issue with the USB-C port? Samsung still uses the lowest grades soldier pennies can buy on their most premium devices.

Looks like you've tried everything basic and the phone's just dead. Could be a motherboard failure. Best to go to Samsung instead of breaking your head, as it's still under warranty. At least that's what I'd do in your position.
Wish you the best.
Try half an hour charging on wireless charger if you haven't tried yet
Saw this happen on a Note 4 back in the day. It wasn't really dead but in a weird power state. Fully charging for a few hours (even though it showed nothing) then holding power and volume up and down got it to reboot.

My old Note 4 went into this state and didnt manage to revive it with Power and Volume Up + Volume Down combo. The only sign that tells me it's not fully dead is the green notification light when I do the above combo.
About weird power states - I had Galaxy Buds Pro, which refused to take any charge - wired charging did not work and wireless either. Only way to revive it was to use wireless power sharing from the phone. Problem did not reappear later. Go figure...
Really? I "didn't root it" as if that is a bad thing
You obviously charged it with faulty charger. I experienced the exact same thing. I was about to cry but then i remembered i was testing a cheap, fake Samsung charger...
Then i plugged the phone into REAL charger, waited for 2-3 minutes, phone was alive with all its glory.
Get a GENUİNE one with GENUİNE Cable, you are good to go.

Had this happen on my old s21u. Contacted support and told them I had done all the steps you did. They had me send it in for repair (was actually 2 months after warranty expired but they still agreed to repair it free of charge) and ended up changing the main board, usbc port and something else. Never happened again after (didn't change chargers or anything). So yeah, contact support that's your best bet.
Is this not a legit Charger ?https://photos.app.goo.gl/X9AGuMiz98q3ya2E7

As for resurrecting your device, you could try some basic troubleshooting steps like a hard reset or checking for any software updates.

It will be hard to do it if he can't even turn on the device i any way... No combination of buttons work, no way to turn it on with charger or ADB...
As its apparently either dead or in power-off state you could try to start it into download-mode by:
1. pressing Vol-Up and Vol-Down together and keep them pressed
2. plugging in a USB-cable connected to either a powered-on computer or a charger while keeping the buttons pressed
Normally it should boot into download mode (you can release the buttons after boot-up ).... Maybe this helps if the power button is broken....

Phones have protection. Fake or real charger shouldn't damage phones.

Can't a power surge damage a device? It can happen either during a storm or by using a non-recommended charger. It can fry certain components, even though phones have protection.

No, it was like... My fake charger suddenly stopped working and my other phone recognized the charger + cable as a DATA TRANSFER DEVICE. It is really hard to describe the experience. No charging, my fake charger was recognized as something else..
The experience was... My S23 Ultra blacked out. I thought it was charging. Then, complete darkness. Didn't respond to power button.. Nothing. I thought it was bricked. Then i got up and found my other charger. Waited.. 10 - 15 seconds later my phone was back again. God i swear, i was shaking with sweat. It has been almost 1 month, my phone is just fine..
That day i decided to go with only geniue products. Maybe my phone protected itself by bricking itself. I really dont know.
To me it sounds like what you experienced was just an empty battery .... without juice in the battery the phone cannot do anything and the defective charger did not charge the phone while you thought it did....
Update from me: I scheduled an appointment from the Samsung site with an authorized service center (Best Buy). They checked my phone and said that they couldn't fix it if it wasn't turning on, and I had to send it to Samsung. That was unexpected.
I sent the phone to Samsung, and today I got a message that they could not reproduce the problem. I wasn't able to communicate with the service worker yet. My concern is that it could be a bad internal cable connection that restored the circuit due to the shipment vibrations. If so, and they will not check it, I could end up with a phone with a faulty connector that could die at any moment (hopefully during the warranty period).
It's also possible that being in the weird power state was fixed by simply letting the phone completely deplete of charge so that it properly turned off, recharging, then rebooting.
I had this problem on my old s7 edge. It seems that samsung never fixed this problem. The screen would stay completely black, unable to do anything until the battery completely drained. The device itself was never rooted or modified. Pretty disappointing it was never fixed.
