Hi readers and experts. Today I had a weird thing happen. As you can see from the image I uploaded my battery drained so rapidly from like 60% to an alert reporting me my battery was critally low. I've searched the forums and can't seem to find anything on this matter. Any assistance would be greatly appreciated.
This is usually an indication of a defect battery.
Thank you for the reply. I still gave the reciept so I'll take it back and see if they can do something about it.

If your tablet is new, a defect battery is rare, most this problem comes from a cracked battery connector. Look other threats you will see the same problem as yours.
Most people think it's battery problem but the root cause is its connector: female white connector, attached to cable, and male black connector, soldered to main board.
90% comes from battery connectors, only 10% comes from bad battery.

I tried the procedure defind in wiki page, but still same
Regards
Sorry man but no help for your battery

Or buy a new battery...
I had this problem, but my solution was a tad risky.
Try discharging the battery COMPLETELY, so letting the Universal die at 66%, then trying to turning it on after that until it simply will not turn on anymore. When you get to that stage, take your A/C charger and plug it into the Universal, allowing it to charge for 9-12hrs (overnight is good). Once it's fully charged (green light where the orange once was) take it off charge and see if that 66% goes any lower. Mine goes to about 12% before it dies now, which is a good day and a bit of charge for me on the stock battery. Not bad, considering I top it up everynight anyway.
The reason it is risky is because I've heard the batteries the Universal use don't like being completely discharged. Not sure on the technical reasons why, they just don't. So I'd consult another before trying this.
go universal's wiki and read the how to fix battery issues!
you may need to recallibrate your battery!
if you update your latest rom, with the battery not fully charged, you need to charge the battery to 100% and flash again you rom....

dont mess! for the cost, buy a new battery. Batteries do wear out. If it is a fake one, they wear out even quicker.
Had the same problem myself, tried loads of stuff. In the end I also bought a new battery.
One thing you could do, is run your uni with out your SD card.
Thanx to you all for replying,
I think new battery suggestion is good, instead of taking nay risk.

PLS help..my phone got drained and when i plugged it in to charge.the led light keep blinking in color orange.is that normal when you charge it from completely drained battery?
what i know is that when you charge your phone it only get solid color orange light
I had the same problem with my old Anker battery, and that battery can only be charged from outside of the phone. What battery do you use?

im using anker battery too. but im charging my phone with the battery inside.
does the anker battery can only be charge outside the phone?am i not doing the proper way?
From my experience, the blinky orange LED indicates that the battery is too low to power on the phone. However, for me at least, the battery charges in this state and the light will eventually become steady orange.
I have experienced that some batteries, if allowed to drain too much, will not recharge easily. This may be your case with your anker.
I am guessing you have tried leaving it plugged in for a while?

I am using anker battery since 4 months never had problem. The blinking light suggests ur batteryis on very low charge less then 5% leave it on charge for a while light will get steady.

Yes, if the batt is zero, the orange light blinks for a few minutes while.charging.... It then turns to solid, and the phone can be switched.on....... Had this experience last week on my wife's sensation xe.

Yep. Remember a wall charger will charge your battery faster then connecting to a computer.

i see i think that would not be a problem.
one more about the anker battery, is it ok to charge the battery in 5v output charger even in the label of the battery it only says 3.7v?
This happens with the normal battery too if you drain it all the way. Just plug it in, let it charge for a minute or 3 and you can turn it on.
If you get the blinking light for more than 5 minutes of charging than your adapter is not giving it enough juice.
Try to get your hands on an old Motorola charger without a a detachable usb wire and plug that in - imo they tend to give a lot more power, and also dont leave it plugged in for more than a few hours since they make your battery kinda hot.
Also, see if your input might be loose, take a tweezer and gently squeeze from top to bottom to make it better for a tighter fit.
Let me know how it goes, cheers

I had a similar problem and this one felt like it was sort of abandoned / unresolved.
I would hate to be the person who uses search but to end up here and find this.
Also, what you wrote seems to be broken. Are you simply informing me that I replied to an old thread or that I can't reply to old threads that aren't closed yet?

Hello everybody!
I have a tranformer tf101 with + / - 6 months of use. After being stopped a few weeks (drained battery) it no longer charge and the system does not recognize the battery. When I plug the charger he starts the boot and not charge the battery. In settings with the battery status is "unknown" and a question mark on top.
I've given a factory reset and nothing. Has also has opened the tablet and unplugged and plugged the battery again. I did a test trying to turn on the device without battery and it turned on like before, like when connected (interrogation and status unknown).
The charger is apparently working, coz is charging dock.
I can not send to warranty because I live in Brazil...
Can anyone give me a light? Have researched a lot and found nothing ...
Thank you all!
Try plugging it into a USB port on your PC and leave it plugged in overnight, turned off.

thanks for the reply! I've done it, one entire day on energy and other day directly to the USB... But nothing!
Well... It might be possible that the battery is busted from being discharged for so long.
Although... Does it work on battery or does it instantly die when you unplug it?
When I disconnect die instantly! But if is on dock, he stay on
Yeah sounds like the battery is busted then. It works from the dock because the dock acts as a charger for the tablet, just like the 'real' charger.
Strange how a battery with six months of use given problem.
Would if I try to put a higher charge on it (20v) and force her to reactivate might work?
Batteries only last so long, and yours sounds like it is shot.
It's very strange that yours went bad after such a short amount of time.
If the charger charges the dock but not the Transformer, then it's not the charger.
You could possibly buy a replacement battery and perform the surgery yourself.
Other than that, RMAing is the only thing that can be done.

Software should not be the problem, right?
I'll try to overload the battery to see if she resurrects.
Then post the result!
thanks all for now!

It not that strange. Its not the age per se thats the issue here - its that it was discharged for so long. Once a battery reaches a certain level, it simply wont charge anymore.
Applying 20v will just blow the fuse in the TF, or worse - fry the whole thing... Dont do that
I read somewhere the fuse blows at 17v or something.
And even if we ignore the tablet for a second, applying higher voltage to the battery will just kill the few cells still alive.
And, in worst case, it can even cause the battery to explode, possibly starting a fire and/or damage a person. Although thats not likely with such a low over-volting as 20v. Im just trying to tell you not to put more voltage on a batter than its designed to get
The only way to 'possibly' repair a dead battery is to trickle-charge it, meaning applying a low voltage over a period of time.
Hello Goatshocker!
This charge 20V must be made directly to the battery and not in TF, it really would kill him! And it would be just a "scare" the battery in about 2 seconds only, the rest of the charge would be normally done after (15v). I've done this with cell phone battery several times!
As the battery is dead it seems, think it's the only option.
But before doing so I'll take you on an assistance to make sure it is the battery.

Ah yes, you are quite correct about that. I completely forgot about that method.
Yes, that might indeed work. But I would only do that as a last-resort, although you seem to be quite out of other alternatives
I took him in an assistance yesterday. Tomorrow should tell me the problem. Depending on the result already do the "scare" on battery.
then put the result here!
I had a similar problem. I tried connecting it to different sockets and it finaly charged.

whath kind of sockets you used?
Unfortunately, the overcharging did not work! The battery was completely dead, not sure how this is possible! But it's a valuable tip! The battery dock is the same tablet. So I changed them and I was working with the tablet and dock only works on energy.
Can anyone advise me a reliable site to purchase this battery? The model is ASUS C21-EP101
ty all!
Left my tablet in my car windows up, on dash in sun! inside a gumdrop case to top it off.
still turns on battery did not swell was at 10% when functioning lipo dissipates over charging through heat so i would assume overheating would drain?
Either way tablet still turns on and tablet did report battery at 11% than after a day reported 4% been at four for over a week now.
it will turn on while plugged in but no charging
I want to take battery out and get voltages from each cell but rather not unwrap it does anyone have diagram to what each wire is?
i fully understand batteries and how to make them alter them and bring back from the dead and i know two are negative and two are positive but the other wires are balance leads either going to other the series bridge or positive or negative terminal on the cell?
any help would be appreciated im about to take it out and give it a go!
if i get no response i will report back with a diagram myself and detailed description of what i did to bring the battery back
both cells are reading 3.67 before the pcb and coming out of the pcb nothing so at least i got my answer that recharging the cells individually isnt gonna fix anything as the pcb fried.
but at least i can make a 2s lipo with the old battery and buy a new battery and still fix my old tf101

Try Another Charger
you have to jump start your battery if you dont even get any feedback from EDL or fastboot. just plug in c type connector, then repeatedly plug in and out your charging adapter. this once brought back my old xperia xa ultra from being completely dead to back to life. also dont drain your battery past %15-20.

I'd like to know your findings from the service center or if you were able to revive your phone. Same thing happened to me. new phone arrived and the battery was drained. LED Lights flicker when plugged in but won't turn on.
the phone is expected to recharge even from a flat 0 battery.

Hi, of course the same thing happened to me. I didn't notice the battery and it ran out to zero. Then I can't charge the phone anymore. I tried different cables, different chargers and nothing. After connecting the charger, only the LED flashes and that's it. I left the phone on the charger for a few hours and something didn't change. Don't have new information on how you ended up in the service? thx
This thing worries me a lot!
Also because I have seen that it is a very common problem among Poco phones.
Even with a lot of attention it can happen, inadvertently ... at that point what do you do?
What if it happens out of warranty?
Is it possible that there is no solution?
Has anybody found a solution to this problem? Which I think is a software/coding problem.
I had the exact same issue in April (phone bought in January) where I didn't notice that the battery had gone flat and plugged the charger in and left it to charge, only it didn't.
Now I was in the position where my son also has the same phone so to diagnose the issue, i took mine apart and removed the charging port and swapped it with his. No change, his phone charged mine didn't.
I then swapped the batteries, his battery would charge in my phone and weirdly my battery would charge from '0' in his phone. So the charging ports and cables were now known to be fine and working, but also the batteries were both able to be charged so it seems it is a software issue.
I now have a new battery on order because he's not got his phone any more
