Samsung Galaxy Tab 3 8.0 (SM-T311) not charging: troubleshooting help needed - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hi there,
I have received this Galaxy Tab 3 (SM-T311) and it does not turn on nor charge.
I have tried the various suggested button presses, I have tried unplugging the battery for a while. Now I am leaving it to charge but this was already tested by the previous owner with no success.
I would like to find out if charger circuit, battery or motherboard need replacement.
I have tested with a multimeter that battery leads show 3.7V - with charger plugged or not. With battery removed the leads show a value of 0.4V.
Can somebody help to figure out whether it is a battery problem, a charger circuit problem or a motherboard problem? I think it might be one of the first two since battery charge should not be so low.
Thanks

By the way, I have already been through this video: https://www.youtube.com/watch?v=m2VJ_VRIRSI
Which comes from this blog post: http://www.bigpicturebigsound.com/Samsung-Galaxy-Tab-3-Won-t-Charge-or-Turn-On---How-to-Fix.shtml
I am not using the original charger and cable but a 2A one, sorry but I do not believe that the original USB cable and PSU would be any different it's like with HDMI, it's a standard. The only thing that could change is the power intensity which is 2A as per original.

Sorry I can't help, except to say it sounds just like my problem. I'd been using mine mainly as a clock/alarm clock using a great alarm app. The battery was good enough to last about 15 or more hours with a clock display on, but then I left for a 2 week vacation, and decided to turn the tablet off rather than leave it on a charger. Came back and it was dead.
I also did all sorts of button presses, used various chargers and cables (I have the original charger, which works for other devices, but didn't help). I disconnected the battery for several hours. Tried charging off a computer USB-2 port. etc, etc. Still, "It's dead, Jim".
I suspect it's the battery, which is pretty old now, and has been left on the charger a lot lately, though not 24 hours a day. Lithium batteries don't like to go totally dead, but I guess that's what happened. If the tablet were still useful to me, I'd try a cheap one from Amazon, not really expecting it to last a long time, but useful to see if it works without losing too much.
I've seen one repair tech who fixed a similar problem by disconnecting the battery and connecting it to a power supply briefly to give the battery enough of a charge to get the phone to start charging it normally. Obviously, this is something that mere mortals would not be able to do.

Broken USB/charging port?

I'm not sure if this is the right place to ask this, please excuse my ignorant.
I have an EVO that won't charge. I've read a lot from Google search results that this is a common problem among many users. However, the port seems to be working, because my computer will recognize the phone and storage when I plug it in. The charge led will come on, and the indicator on the phone will say that it's charging, but the phone is actually only discharging while plugged in. Eventually the led will turn itself off, and the phone stops telling me that it's charging when the battery is down to its last drop.
I hope that someone with similar problem can help me with fixing this, or if anyone cause tell me if it's possible to fix? I want to send it in to HTC since I think the phone is under warranty, even if I don't have the protection plan from Sprint? The problem is the touch glass is cracks, and I don't know if they'll fix the USB port without saying that I broke it and won't cover that under the warranty. I want to buy a new screen and replace the broken one, but if I open up the phone it would void the warranty as well...
So I'm stuck with a discharging phone, cracked screen, and having to carry around 3 separate batteries everyday, and I have no idea what step I need to take.
Please help?
Have you tried plugging it into another charger? It may just be the charger that is screwed up. If this behavior pattern is consistent across multiple chargers then you may want to talk to Sprint to see what options you have.

Doubt it's the charger as it was stated that the computer connection works - should get a bit of a charge from that. I agree that a Sprint visit is due.
Just went through this myself! Would plug my phone in before bed and wake up with the phone at 2% or so. Thought it was the battery- so i took my battery to have the sprint store check it, they did say it was bad. So i bought 2 batteries off ebay.
I got the batteries and still had the issue. So then I took my phone to the sprint store and had them check the micro-usb port. They said it was fine and they cleaned it out cause dirt/dust was in it. Still had the problem..
So I bought a new micro-usb cable of monoprice (still using the same wall charger) , and that solved the issue! Had a bad cable. Now my phone charges super quickly in matter of 4hrs.
It could still be the charger. The USB cable sends data and power through different pins. So a bad cable could still transfer data while not pushing a charge.

It's gotta be the port happen to mine and I was able to get it fix as long as the port was still attached to the motherboard, if its not attached then have to go thru the insurance.
EVO with Identity Crisis
I was able to connect to my computer and send data just fine with the old (broken) usb cable.
I've tried three different cable and a car charger, same result; they all say the phone is charging but it only gets discharged. USB/storage connection works. Last time the Sprint store said the battery is faulty, but I have 3 different ones and neither will get charged with the phone plugged in, an external charger will work.

Definitely sounds like a port issue then. If you return to Sprint and review what you've done, as well as the result of your previous trip, then they should be able to take care of you. If they try to tell you it's the battery again just stand your ground. Good luck.
I had a similar issue. I tried everything. It wasn't until I found my HTC cable that it started charging again. I work in IT and tried cables from everything I could get my hands on (blackberries, external drives etc. ) The cable that came with my phone was the only thing that worked.

If you replaced the port yourself, I would love to know how to do it!
Took the phone back to Sprint and they said there's nothing they can do. I don't have the protection plan so I couldn't even pay the $100 to get it replaced (although I probably wouldn't as I can upgrade my contract and get a new phone soon). They also told me that HTC wouldn't cover it under their warranty because the screen is cracked and they will blame that on me for misused. I tried to check the warranty policy on HTC, but the page is not even available. Does anyone have experience dealing with HTC? I bought a replacement screen, I'd like to replace the screen but don't want to open up the phone if there's a chance HTC will fix the USB port...
HTC EVO 4G Won't - Stopped Charging Battery Issue
Hey Guys,
Two nights ago I woke up to an EVO that was plugged in with a Cellet
extractable charging cord, as it is just about every night. But, the phone was
still showing that it was charging the battery, animation with lighting bolt,
at only 50% charged after about 6.5 hours of charging. Hmmm....
The latter after trying to charge in the coffee shop first with Cellet chord in the
wall then a portable 3500mah solar portable charger; the phone not seeming to
charge at or past 50% charged.
My EVO is rooted but still with the stock ROM and the gingerbread 2.3.3 OTA
update. The battery is a Seido 1750mah and SetCPU is at 245 - 998mhz. The
phone has only been rooted for a few weeks, but I don't see where rooting
would interfere with battery charging.
I've pulled the battery out, several times to no avail. Switched back to the
stock battery, same results. However, if the battery is less than 50% full
the phone will charge the battery to 25% or 50%, weird. If the battery is
at 75% or more full, the phone will top off the charge to a green LED at 100%,
sometimes. Sometimes it won't fully charge the battery. Weird.
I read different posts regarding poor USB chords so I pulled out the stock
micro USB to USB, a charge only chord I figured, and am trying to top
off the Seido battery, which it seems to be doing as it's now full green but
still charging as the animation shows the bolt in the battery and the LED
is still orange.
If put the batteries in the Seido wall charger, the thing the size of a deck
of cards, both batteries fully charge.
I also use Screen Off by Iwashi Soft. That app has worked pretty well with just
a little funkiness now and then. However, while plugged in, I hit the power
button, instead of the home button to turn on the home screen. The phone
wouldn't open to any screen nor would turn on or off. So I ended up
yanking the battery to turn it off then reinstalled battery and turned phone back
on. I don't know if that had any effect on the charging issue, but I took
the icon off the homescreen and am using the power button only, for now.
I don't think both batteries are faulty at the same time at this point. I
don't know if the screen off app caused some wake issue that interferes with
charging the battery.
I do know that when plugging in the phone to charge there's a bit of clunkiness
initially as the phone locks for a second before allowing use for screen or app
and that's always been the case since the gb update. Also, the LED doesn't
always turn green from amber when fully charged with the screen off until
you reboot or use the phone in some way while still plugged in. So there is
some kind of wake issue in the stock ROM. But the latter has never stopped
the battery from charging.
I do know that Plume, the twitter app, started acting clunky with not updating
in the background unless I opened the app at least once after a reboot. But
I don't know if the latter is a wake issue.
Battery still seems normal. Heavy normal use, lots of SMS, tweets, Pulse reading,
Dolphin browsing, I'll kill 50% or more of the battery in 4+ hours. Otherwise, the
phone mostly in standby with periodic email and twitter reads, the battery lasts
all day or more than 24 hours. But the latter rarely happens anymore because I'm
a user.
The battery just went full charge with the stock charging cable just now.
This morning, I woke up with a dead phone, auto shutoff even though it was
plugged in which I did after solitaire and before going to sleep; as a charging
test.
I don't know if it's the phone or the Cellet retractable cord or both that's
stopping the battery from fully charging normally and consistently. I'll need
to get another data-charge combo chord and do more testing; and a new ROM.
Any ideas anybody?
try a new rom and also try using the stock charger and usb cable. Check inside your usb port on your phone for dust as well. Also go into recovery and wipe your battery stats. In the wipe menu for amonRa and under advanced (maybe here, i dont use cwm on my phone) in clockworkmod. also wipe your dalvik-cache just to clear any issues you may have, restart and give it a test. good luck
I just bought a phone with a broken charger port. Broke clean off the board, so my next step is to try to get liquid solder and stick it to the board. Did you take ur phone apart to see if the port is lose?
So I used the stock USB charging chord. Sure enough, it charged the phone.
Then I tried the portable charger at the coffee shop, worked. So the Cellet retractable
chord obviously had a short or something damaged/shorted for the charging part of
the cable after a year + of use and abuse.
What I don't understand, and haven't researched, is why there are charge only
chords; the stock USB HTC chord charges the phone, but the PC won't recognize
the phone's Micro SD card or the phone as an external drive. I presume the duo use
chords have a data path as well as a charging path. And yes, I know to switch the
phone from charge only to disk drive. The Cellet chord would provide the PC with
recognition for the phone's drive.
Considering the latter, what I'm not sure of, and haven't researched, is why when
the phone stopped charging, the chord eventually stopped charging, the phone
status still showed it as charging; the amber LED light on and the battery icon
in charging animation with white bolt showing? I presume that the charging path
still triggered the charging status, except once when I turned the screen back
on the battery icon was not animated and the white bolt not showing so I unplugged
the chord then plugged it back in where the battery icon animation continued.
Fortunately, or not, this forum returned 600+ results for 'battery not charging' and after
sifting through a few, the charging chord was mentioned which prevented a Sprint trip
and me contacting Seido; thankfully.
So I think manufacturers and ROM/kernel developers should visit this issue as a chord
that actually is not charging, or charging at an absurdly low rate, should trigger some alert
and not show a battery icon animation that appears to be charging normally.

[Q] A100 Powers OFF when charger is connected.

Recently successfully replaced the LCD screen on my Acer A100. Device worked fine for some time after that repair. Wanting to get a secondary charger for use at work I went to radio shack. Sales "tech" tried several different adapters, found one that fit inside he port, but wiggled. She plugged it in but device wasn't showing a charge. Decided to order one from online. At home the device still would not charge with its own charger. Thought maybe the charger was faulty. Ordered two more. Still the A100 turned off when charger plugged in. Figured tech had burned out the a/c port. Ordered and installed a new one. Still A100 turns off immediately when charger is plugged in. I have 3 chargers now - same results with all 3. Have now ordered a docking station to utilize (hopefully) charging ability through 40 pin connector.
If this connection creates same shut down am I looking at a battery replacement? AM sitting at 33% battery level now, device shut down completely.
Acer wants 199.00 prepaid to submit to them for repair - this is more than I paid for the device! Not really an expense I am willing to pay if all it needs is a battery. There is no erratic behavior , just immediate shutdown as soon as a charger is connected. Any ideas?

If its doing it on 3 chargers its sounding more like a board charging circuit issue. You could remove the battery and then see if it behaves normally, that'll be battery or board right there. Or if you have a multi meter test output at the battery connector.

Don't have a multi meter. Tried connection via new docking station, got same response: device immediately shut off. Tried your suggestion, disconnected battery connected to docking station, got immediate shut off. Same with charger via a/c port. :crying: Mainboard is out? But Device responds and acts normal when in battery mode - or is this isolated to the charging circuit part of the main board?
Thanks for the suggestion!

Sounds like its tripping on the charger circuit and cutting out, like a breaker tripping. IMO look carefully for any shorts on the boards, even something stupid like dog hair can cause strange things to happen. A good blasting with air wouldn't hurt either. It could even be the dock port as it does charge from there and is subject to debris also.

Thanks again for more suggestions. Yup I have been over the board and all connections with a looking glass. Changed out the A/C dock port. My suspicion is that when the Radio Shack tech powered up the "Almost fits" adapter it blew whatever breaker the board has.
When I had it connected to the docking station with the battery disconnected, it powered on, then immediately shut off. So this definitely sounds like a "blown fuse". I completely disassembled and reassembled it again (except for the LCD screen) and checked all connections and plugs. Nothing visible to indicate a burnout or cross connection.
No odd smells either. Probably some teensy weensy transistor or resistor or something. I am not an electrician - just good at R & R.
Another visit to ebay and I am parting with 50 bucks for a "factory refurbished" motherboard. In the mean time, my beloved tablet will await further surgery. Will keep you posted. Board should be here by Saturday. I hope so - battery is down to 27%. Thanks again for weighing in!

To bad considering the crappy battery life so its not like you can charge some other way and swap the battery around.
Example, I have a bricked unit that charges but doesn't otherwise work, so I mean using my bricked board to charge it and the non charge board for use. The a100 isn't really a good setup for swapping around lol. I may actually be interested in that board now that I think about it...

If I could figure out a way to charge the battery OTHER than through the board - I would! Which got me to thinking. One COULD get a second rear panel, cut a door in it, install teensy weensy hinges or create a hinge with cloth tape. then make some sort of extension cord for the battery charging cord, plug it in to the "external" charging board and refill the battery that way.
With a working board and the right know how, one could just extract the board, put it in a box and make a charger out of it too.
But that is just my brain rattling around ideas. :silly: Hopefully this new "refurbished" mother board will do the trick and I will learn my lesson and NEVER let a sales "tech" attempt trial adapters! at 10 minutes to 9pm tonight it was in Texas....
Until I CANNOT use it, I didn't realize how MUCH I used this little tablet!
now it blinks orange?
Oh fer cryin out loud! The motherboard has arrived, I have installed it. Can plug n the charger and drop it onto the docking station and now I get the same response for both charging options: Charge LED lights up orange solid for just about 60 seconds, then begins blinking. Device doesn't respond when power button is pushed UNLESS it is plugged in, and then it just sits at the "ACER" screen.led changes to blue.
OK, wait a minute, this is the third time I have turned it on while plugged in. Acer screen has moved to Android, Device has started. Battery icon showing a question mark. 23%
Turned off, turned back on, now battery shows only 3%????
Think I saw something on the forums about that. will go on a quest.
Finally charging again!
Shhh, don't want to disturb my device....
Found folks on other forums with similar issues of the Acer A100 tablet showing only 3% charge. I removed and inserted the charging pin several times, the device would show solid orange led for about one minute then start blinking. Turned the device on when charger plugged in, unlocked the screen, then with device still plugged in I shut it down completely. Removed charger. Plugged it back in and so far the led is staying at solid orange.
Please keep your fingers crossed for me! This has been quite the roller coaster ride of discovery. Will leave it be for overnight (what is left of the overnight). Then peek at it in the morning. With any luck at all it will have accepted a full charge and I will be greeted with a functioning device! I almost want to learn a new trade..
well now that is weird, got up this morning to a nice blue charge indicator. Yay! Unplugged charger, press on button, hold, hold, hold, hold, hold and device does not start up. Dang it! Plugged it back in, led went solid orange, then started blinking again! Pressed and held on button. Device came on. battery meter shows 3% and a question mark! HUH?
have device plugged in, settings of course show android version 3.2.1 for this motherboard. Guess I need to upgrade it to ICS maybe that will resolve this weird battery issue? Hope soemone here has ideas, feels like I am soooo close to resolving this.
I read the upper posts.
Now I want to share my experience regarding battery load sharing:
I have allso problems to charge the battery.
I have on my tab, for example, 40% of battery power.
I turn my tab off.
When i plugged the charging cable in it shows me the orange led for load.
After two hours or more i turned the tab on.
It shows me not more than 40% but only 37% or so.
So not loaded. This was a bad sign....
I dont no was happend.
I get a little bit nervous but when the tab not get power it doesnt work....
After two/three hours the battery was empty.
Now i can only start my tab while plugged the charging cabel in because the battery will not load.
I have tried several options to find a solution (disconnect the battery, install a new battery, etc. ....).
My solution was fairly straightforward:
I open the tab. Look where the power comes in.
Of the charging socket go four (two red and two black) cable to the motherboard and from the motherboard it goes seven (two red, two black and for me not so important three other coloured cabels) to the battery.
I organized four thin wire and soldered it from the charging socket directly to the battery (of course red to red black to black ).
The result:
When i plugged the charging cabel in while android is running i get no information to load and it shows me not to.
But when i turned the tab off and on again it shows me that it has the battery charged :fingers-crossed: .
After on night while the charger plugged in the battery is fully loaded!!
And of course i get the information in android the discharging of the battery but this is an normaly thing!
So, the problem to load the battery for me is solved .
I hope it helps a little bit for everyone!

I really hope other isn't any voltage or amperage changes needed of that can blow that battery up real quick, plus it can't stop charging, you'll need to monitor that yourself.
Thanks for the info though, it does appear to be yet another somewhat common bug these have that can be addressed by a user if they feel the need to.

Not switch the charger off when the battery is full?
I think the charger there is a shutdown would otherwise overload the battery, right?
Or do this the motherboard?
Anyway, for me the tab is fully working now and if the battery is broken, it is not a big expense to replace them .

I was saying the board is in charge of cutting the battery charge off, not the charger itself so maybe keep an eye on it, its a good way for an explosion or fire.

A100 tablet not charging still
Frischies is much braver than I am.
Wiring the battery direct to the charging port- I would definitely worry about burning up the battery or causing a fire - especially while charging when I sleep. I have had more than my fair share of run ins with fire.
The Motherboard I ordered arrived and I installed it. It was listed as "factory refurbished", but unfortunately will not accept a charge. I thought it had charged overnight at one point, but all it does is blink orange and the battery reads 3% or 0%. Turning the device off when plugged in and doing a reset has not helped. The vendor has been gracious to do a replacement, so I will follow that route until I get a working motherboard.
I have discovered that the docking station will be a welcome addition to my Acer tablet paraphernalia! Although this model docking station isn't the one that allows HDMI throughput, it still will be nice for music, and other media. A Bluetooth keyboard and the tablet will offer yet another computer tool!
First things first though, get the tablet to accept a charge - until then it is a really wide flat paper weight! I am getting VERY adept at opening the tablet and removing the internals!
It is working again! The motherboard sent was defective but vendor issued an RMA. Received the replacement yesterday, installed it last night. Charged over night and fully functional this morning! Ahhh it feels good to have my little buddy back again. Didn't realize how much I used it, until I couldn't use it! Thanks to all for the help.

Note 8 5110 dead?

The other day I plugged in the Note 8 at night, all was fine. When I picked it up the next day, it was totally dead. There is no charging light. I have tried several chargers. I have tried holding down the power button for over a minute. I took the back off and pulled the battery and reinstalled it. Nothing. Tried multiple chargers (all of which are in working order and several that were used to charge this device previously)
Could this possibly be a bad battery? I would try replacing the battery if it seemed like a possibility, but I've never had a battery go instantly bad. It would make more sense if it just wasn't holding a charge but the charging light would still be on.
It's just out of warranty by a month. Anyone think it's worth spending the money on a new battery?
Thanks in advance for any wisdom
My 5110 does not have a removable battery, though I had two bad samsung USB charging cables, and went to Blackberry and Samsung cables. My second Samsung cable melted down and just about caused a fire at the tablet's connector.

Thanks for your response. It's not officially removable, but it just involves removing the back and then 8 screws. I'm certain it's not a cable problem. I've tried most every cable and charger I have and they all work on other devices.
I guess I'm a little confused. Where is the charging light? There aren't any LED's on the 5110 and the charger doesn't have any either.
As mentioned, the Note 8's battery is not intended to be replacable, as other phone batteries are. It is doable, and would be my first attempt as it sounds like you've tried multiple chargers.
Beyond that, I doubt anyone here would be able to diagnose without seeing it personally.

Ok, I have to admit it, I cannot actually remember what it looked like when powered off and charging (mainly because it is rarely powered off). Can someone tell me - Isn't there a battery symbol that displays in the middle of the screen? If so, even if the battery was totally honked, my uneducated guess is that it would still show the battery symbol perhaps with a yellow triangle.
If there is not supposed to be any charging indication at all, then my hopes are higher, because that's what I see.
Either way, I've got a battery on order, so I'll let you know what happens.

The only battery indicators are on the screen. When it's powered off and charging you should see the battery in the center charging up. If the battery is hosed it'd be like no battery is in there at all, and on Samsung devices you won't see anything on the screen if no battery is present while power is plugged in.
My clients frequently have the microUSB port (charger port) go bad on tablets in general. If you've got a can of air, blow out the inside of that port (You can also use a compressed air line, but be a little more careful with that). You might also benefit by checking out the condition of the contact pins in there.
Other than that, try a different cable and a different USB charging brick. Try to use the original one that came with it, then try one that has an output of at least 1 amp (The one that came with mine was a 2 amp, but it charges alright with 1 amp). And check your outlet. It sounds stupid, but you never know.

Cant charge now....

Got down to around 15% and then plugged in. Noticed level continued to drop. Opened battery page and see this:
Plugged in, Can't charge now.
Did a restart and same thing. If I flip the USB connector 180degrees, it charges. Swapped ends with the wall part of charger. Same thing....only charges with one side of usbb cable pointed up.
What up?

Sounds like a bad port, or cable. If another charger or cable doesn't work, RMA that puppy. Of course, Google support will tell you to do a factory reset first. So be ready ?

On 30 minute hold now.
Flipping the end on the wall doesn't matter. Flipping the cable around doesn't matter. Whichever end is plugged into the phone only works on one side. Weird....I thought they were the same.
No spare USB C cables. May be able to test with an A to C in a few minutes...

Mine was taking 8 hours to charge. Wouldn't charge if on, just couldn't keep up. Rma'd it. Told the guy I'd already tried the usual stuff. He said ok and authorized a new one. Took like 3 minutes.

But did you have a "can't charge right now" message showing up? I've never seen that.
Troubleshooting per Google...
Tried full off instead of restart
Tried safe mode
Same behavior.
I have tested with factory A to C cable and iPad brick.

Send it back bruh! :good:
.. previous post truncated. Copy paste always does that in xda app?
I have tested with factory A to C cable and iPad brick. Seems to work fine either way I flip the cable. But I do notice the above msg for a half second when first plugging in, then switches to charging.
With my stock charger, phone does the same with one orientation (brief msg and then charging)....but NOT fast charging.
With the other C cable orientation, it cycles several times between not connected at all and then stays on msg above.
All for now.
Would like to test with a different USB C cables....but not available now.
Is it normal when plugging in, to momentarily flash that can't charging msg? Never noticed it before, but wasn't looking
I was wrong about charging rapidly. On the lock screen, using the orientation that works, it does show charging rapidly.
BUT Ampere app (which measures charging current) only registers about 1mA.
Thanks

1) Yes you're right. It does momentarily flash "can't charge right now" for me. Literally a split second flash. Wouldn't see it unless you were looking for it.
2) You really can't trust apps for measuring charging current. It's especially inaccurate when the screen is off which you need to do to check it. If anything, it would close to accurate if you had your screen off for 5-10 minutes then checked it quickly before it throttles the charging down. Only way for an accurate measurement is a is a power meter like this:

Thanks....
True, charging current with Ampere is less than accurate with screen on. Accubattery however will calculate charging with screen off. Would be interesting to see how that compares to the USB meter.
Was able to test another brick/C to C cable combination and it worked fine both ways. My cable worked in 3rd party brick. Using my brick and either cable, it will only charge in one direction.
So I guess my brick is bricked.... will ask G for replacement.
Well the sent a new brick. By the time I got it, things seemed to be working ok for a while.
But last night my phone was charging next to my bed. Middle of the night I noticed it was on. I grabbed it and unplugged the USB C. The cable connector was extremely hot. Didn't think much of it.
Now, near end of day, I try to charge again. Won't charge. Turned ohone off and tried to charge. Plug gets way hot, but no charging indication.
Back to Google support.

@akenis Did you ever sort this out?
I'm having the *EXACT* behavior, but on a OP6, the same "plugged in, can't charge right now" message.
If I reboot, I get one charge (still with the brief flash message "...can't charge") and then it charges, until I unplug it. Once unplugged it won't charge again, until rebooted.
Same charge-source/cables/Qi receiver that my OP5T had, and my wife now does, zero issues on it (the Qi pad is my main charge source, typical is about 500-700ma, do-able, for me). Re-tested the 5T on a couple of the cable/charger combos, absolutely no issues, it charges every time.
If I use their Dash charger (which I rarely do, because my Qi receiver is stuck on the back, under a case), it gets around this, but it's not a great solution for me; I only have one of them, and we have Qi chargers "everywhere", it seems ;-]
I had a 6P prior, my mea culpa for posting on a Pixel thread, with OP repro instance. I do think these are both s/w related, and probably related to some kernel issue, that's persisting in Oreo builds. I bet if I were really motivated, I could find this in several other brand devices, in various other forums...

I think it was hardware. On my 3rd 2XL. 1st one ended up smoking at us port. The replacement wouldn't route audio through us port.

Dead after Qi charging?!

Hi Guys,
I'm hoping someone can point me in the right direction here, firstly, I have indeed used the search function and I am more than aware of the many cases of dead tablets with charging issues. As such, I have also tried all of the proposed solutions with no joy so far....
So my N7 2013 is basically my old work tablet that was never used, literally sat in my drawer for 3 years not even out of the box but a couple of years ago I started to use it, loaded it up with a custom ROM and everything was well, no issues whatsoever as it was a brand new tablet. Now, my PC monitor has a QI charger in the base and I had been charging the tablet on there for months but one day it was left on there all day and when I got back later on that day, it was dead..... It was warm to the touch, normal for charging but would not power on. No indicator light or anything.
When plugging in the usb cable to charge, I get nothing, no indicator or anything.
I have held the power button for well over a minute and nothing.
I have held the power and volume down button for well over a minute and nothing.
I have done both of the above with power plugged in and not plugged in, nothing.
I have replaced the battery with a brand new one, nothing.
I have checked the contacts for the QI charging meet the tabs as I read this and the USB charging is on the same circuit, nothing.
I have vaguely read something about quite literally "jump starting" dead N7's and I have not yet gone down this road, I'm hoping there is something obvious I have missed.
Can anyone suggest anything else?
Thanks in advance! :good:

Hi, the new battery may be faulty too. Measure its voltage - if it is below 3V, it is faulty for sure.
If it is above 3.0V but below 4.0V, recharge it externally in any Lipo charger to 4.2V, then re-connect it to N7 and try to power up.
Your N7 may work on pre-charged battery, but be unable to recharge it because of an internal fault. There is no N7 schematic available and component-level repair is unlikely, but if it works on pre-charged battery then you could do "no battery mod" and keep this great tablet alive and useful. So, do the above tests and search for the mod, which is very popular for car use.
:highfive:

Thanks for the reply, I hadn't thought to check the new battery.... I'll do that tonight..... The "no battery" mod is no good to me unfortunately as I want the tablet as a tablet..... I already have an android head unit in my car...
The thing I find slightly jarring is that if i put the tablet on my wireless charger, it gets really warm at the top end of the tablet but with the USB, literally nothing. The charging indicator has not been seen since it first wouldn't turn on.

Ok, so I've tested both the old and new battery and both are at a solid 3.8v as per the battery spec
