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 recently received my fresh NT from the ebay sale, and yesterday had it running CM7, with CWM installed internally. Everything was fine with the world.
Today, I wake up and find it boot looping constantly.
- When plugged into USB, it boot loops constantly. As soon as the N screen disappears, it restarts. I can't even get it to turn off.
- When disconnected from USB, I can't even get it to turn on. Period.
- When disconnected from USB when the N screen is showing, it instantly shuts off.
- 8 Reboot trick doesn't work, booting onto a CWM or stock-flashing SDCard doesn't work, acclaim doesn't work.
Almost sounds like a dead battery, considering the instant shut-off when unplugged, but it can't charge because it's constantly trying to turn on. Any advice?
Leave it on the charger and don't touch it for about half an hour.

Unfortunately, it's degraded to the point that it won't even turn on -- plugged in or not. I'm going to go ahead and pass it off as a hardware failure and see if I can get an exchange.
mine is doing this , i didnt charge it last night , when i woke up it went to cynoboot showed 12 percent batt and now its looping just like what you said yours was , what is the end result ?
i've already taken the back off i have access to the batt connector im thinking about maybe rigging up a trickle charger to that directly also i dont have the BN charge cable im using a micro usb and its worked well so far, i did order a BN cable it should be home by the time i get home though , im guessing i need to find an alternative way to recharge this battery
id like to know if you got an exchange ? or if you still have the tablet ? im going to try a few other things too but if you still have yours and i figure it out ill pm it to you
solution
dude sorry to dump this on you years after wards , crack it open , flip it over to its back flip up the sd card cover take out the torx 5 screws , use a small flat head screw driver pop out the back tabs once its open , disconnect the battery and the other cable up top , i left em disconnected and tapped them with my volt meter , i saw a capp drain flat on the outside red and outside black lines, then after a few minuets reconnect the two cables , plug it into your power and leave it for 2 hours your now at screen of death and just need to charge the battery,
manually forced the device to reset , it keep running in circles and would never charge , just disconnect the batt man ...
mines on and at 20 % batt and charging ...
later
I have the same problem. Would letting it drained completely and recharge work? I don't have the right tiny screw driver for it. :crying:
I think the battery is still good. For me, It's able to get into CWM and install the latest cm-10.2-20130811-UNOFFICIAL-acclaim.zip. Just, when reboot, it goes into the endless booting "N" loop.
Thanks.

Had almost the same problem as you. Bought a Nook Color off eBay. Battery was discharged to 0%. I didn't have the original Nook Color charger cable so I thought I was fscked. I had a few microUSB chargers lying around. I used an old Motorola flip-phone charger to charge it back to life.
Get ANY microUSB charger, like for an old cellphone, or buy one (they're cheap off the streets). Plug it in and let it charge overnight. Do NOT under any circumstances press the power button or you'll have to restart the charging process. The next morning my Nook Color booted up (although it had only 18% charge) and everything was fine (poor seller sold it on eBay for parts, I got it for $28 in total LOL, but I knew it was fine).

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.
I am sure this issue is somewhere on the forum, but I am unable to find it. I have had some charging issues with my Galaxy Tab s10. My husband has bought both a battery and a usb port but I'd like to check here before we crack it open.
There are a few things going on:
Tablet charges to a point then stops
Tablet won't charge at all
Tablet flashes on and off while charging
Recently I let it die completely, it then charged to 100% but now all of the above is going on
I have tried a different micro usb, a different wall charger, letting it die and recharging (which let it go to 100% but problems still happening)., I tired wiping and factory reset...
I understand that the charger is pretty specific to the tablet so a generic one likely won't cut it. I am hoping to figure out what could be going on here.
Any feedback is appreciated.
Found Solution
So after more digging I found a solution on another forum, so simple. Everything is normal again. I thought I'd share in case anyone had a similar issue.
"Try holding all the buttons (volume up and down, and power) in at the same time for about ten seconds while the device is plugged into the charger.
This seems to reset the tablet and its charging circuit.
You may have to allow it to charge some more after that before it will power on.
The lithium ion batteries in these tablets aren't designed to be completely drained, and doing so can damage them."
Dug out my trusty Z3TC 16GB WiFi to browse the web and its dead and refuses to charge on 4+ different chargers. Won't respond to power+vol up or show any activity.
Software was fine when I last checked, running CM12.1 and no issues.
Anyone see a similar issue and know if the battery is likely to have failed or something more fundamental?
I'm ordering a pogo pin charger to see if that works, had a couple in the past but the connecting wires in the stand broke.

Happened to me. Try this: NEVER LET IT GO FULLY DEAD
https://www.ifixit.com/Answers/View/225037/No+Power+&+Not+Charging
Yup, saw that thread. Looks like I'm out of luck as I certainly can't resolder any of the components.
did u try with a quick charger?
Peace to all
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
or u can try press the tiny reset button near to usb port.here says that nothing is being erased.

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.
glad to hear!so can u tell us the working process so just us to know just in case?....

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! ?
Peace to all
Dude glad you got it working. I love mine but i have it rooted. hoping that the latest stamina battery return update is rootable
I recently picked up this galaxy s6 edge from a friend that upgraded to a new phone. It won't turn on, neither to android recovery, nor to download mode nor the android. I charged it via wireless charging overnight and i tried for around an hour with a usb cable. What do i do?
same issue i am facing, i tried original charger, wireless charger and fast chargers from many different brands. but all failed. The device only gets warm/hot while charging and nothing happens. neither download mode nor recovery mode works. I am kind pf stuck without any solution, my device was used very rarely and its like an brand new device. Doesn't know what to do, if you find any solution then please let me know too. thanks in advance
Same problem. If I press power button very long, blue light comes on. Then it's stuck and stays like this until battery is flat. Battery charging is not possible: device heats up (tried USB and Qi), but battery doesn't take any charge.
So I opened the S6 and checked the battery directly. I can charge it directly with a lab power supply and when I plug it in and press power button, the blue notification light comes on again until battery is empty again. I can also see that only ICs get hot, but not the battery when plugging in USB.
So, it's definitely some hardware fault. I suspect power IC that is not able to power up the screen. But I don't know. I will investigate further but it looks difficult. However, I have seen many YouTube videos with same symptoms, but problem was always different than mine :/
Hi guys,
This thread is 2 months old, any of you managed to fix the problem?
I am having very similar problem. My phone was on a shelf for about a year and a half. Before now it was working perfectly. Now I can't charge it via USB or power adapter. When trying to power it up or get into download or recovery mode, nothing happens. Computer does not see it. Tried different cables, USB ports, power adapters..nothing.
The only thing that is happening to the phone is the battery logo appears when trying to charge it, though the green bar does not go over battery, only the empty grey battery with lightning icon in the middle. Also the screen does not go dark after a few seconds as it should and the red/blue LED does not turn on.
Is this the signal from the phone, that the battery is to deeply dischareged and cannot be charged again? I am googling all over the web and can't find anybody talking about what phone does in case of to low voltage on battery.
PS back does not seem to be bloated, USB port was working perfectly last time used
Please try to help, you are my last stop before opening the phone and start probing the poop out of motherboard to see what gave.
EDIT: something interesting happened just about an hour after my post. The battery suddenly started showing % of charge and the green bar started running, computer recognized the phone.. as everything should be.
My FIX: leave the phone pluged in and charging for about 3days and it will start working again.
My semi professional explenation of fix and problem: the phone has a ''backup or reserve'' battery. It is actually main battery but the last I think I read somewhere it is 20% of capacity, is reserved for phone exclusively for the clock and all other electronics that need power when switched off. Now these 20% probably were discharged due to laying around for almost 2 years.
It took me 3 days of charging to fill up these ''20%'' I guess. Probably because Lithium batteries are charged VERY slow at very start and end. This is safty procedure for ALL Li batteries.
If any expert can confirm my conclusion please do so, to help other people.
To answer partialy to my question: The phone tells you battery is ''deep'' discharged when you only see the charge icon without the green bar.
In the mean time I was writing this edit I came up to 4% battery and turned it on!
