I created this question and my browser locked up during the post. I hope this does not show up twice.
Does anyone know if the calibration.ini would calibrate any differently when the tablet is plugged into the AC charger VS when the tablet is charged up but running on battery power?
Someone had posted in another thread that his touch screen seems more sensative when plugged into AC power.
That makes me wonder, do you think the calibration should be done with Battery Power or when the AC Power adapter is plugged in?
I don't think it would matter, but you could always try it.
Fyi. Gojimi ported an app to the caliberation without the ini file. Check out the gtab app and theme section. So, you can try with or with ac more easily.
Possibly being connected to the AC adapter impacts the capacitive touch screen

I woke up to find my SDA powered off and unable to power on, which was odd considering it was plugged in to a (Motorola) charger.
Since the orange charge light doesn't come on at all, I suspect it's just a dead battery. I've touched the battery contacts to a battery tester with no response - as if the battery is totally dead, which is promising. However, I can't be sure I'm doing it correctly since I've never tried this on a battery I know is working.
There are 4 contacts on the battery, and I'm wondering if there's more to it - like needing to have 2 contacts touching the positive lead and the other 2 touching the negative lead.
Can someone try testing their battery and see which contacts give a live (charged) result?
Thanks

Normally you shouldn't try to use chargers not designed for your phone. What has probably happened is that there wasn't enough current output in the charger, and it completely drained your battery. Your battery is probably fine. Get a proper SDA charger and try charging it again. You can even take it to a store and ask them to plug it in for 15 minutes while you browse the new phones.
Yeah - I lost the original charger, but I've been charging with this Motorola one (output 5V / 550 mAh) and via USB for the past 6 months without problem. I still think it may be the battery because it was at 50% when I went to sleep.
What are the output specs of the original charger?

The stock HTC charger (model ADP-5FH K) has output of 1A at 5V. But if you had no trouble charging before it shouldn't be a issue, unless the charger/battery is faulty.
If you have a multimeter you can verify this. To check if your battery is charged place contacts in (+) and (-) contacts on your battery and it should show ~3.7V. I just tried this.

Thanks, silencer. I don't have a multi-meter, but I was using the battery tester as a way to gauge whether it was putting out any current at all, and it sounds like it's not. You were testing the 1st and 4th contacts?
I have read elsewhere that if your battery goes below 10-20% you won't be able to charge it with anything but the stock charger, so I think that's the problem, but I'll probably order a new battery as well just in case.
Yes I check the voltage between first and forth contact. What sort of battery tester are you using? Is there a digital read out display?
You can also try a USB to mini-usb cable to see if the battery get charged. From what I can remember USB ports are designed to give 500mA at 5V, but I have charged my phone when it was flat using a USB cable.
To follow-up in case anyone has this problem in the future: I ordered a new original charger (ADP-5FH) off eBay and with it, the phone's orange charge light came on right away and after giving it a full charge my phone is back up and running.
I'm inclined to think that it's not the difference in mAh of the original charger (1000mAh) vs USB charging (500mAh), but that there is something unique to the original charger which can "turn on" the charging when the battery is completely dead - perhaps something communicated by one of the extra pins in the mini-USB connection.
Hi all,
Sorry in advance if I'm asking for something that has been answered before.
I have seen lots of threads that talked about the Asus Transformer tf101 and tf101G that doesn't charge correctly.
My TF101G stopped charging after it was fully drained after the kids played some games on it. When I plugged it in to charge the TF screen came on with a big battery indicator which showed a empty battery with red at the bottom. Then it just goes off. When trying to switch on again it just briefly flashes this battery and goes off again.
I left the TF to "charge" overnight and this morning after about 6 hours of charging it had +-14% battery life.
So it appears that the charger still trickle charges the TF when it completely off, but doesn't want to charge when it powered on.
Also, the TF recognizes the cable when it gets plugged in. If off and with some power in the battery the TF starts to boot up, but no charge indicator is showed when booted and battery drains as per normal.
Could it be that this is a software issue? I would guess not, but then again I ask myself if the charger or USB cable was broken then it wouldn't trickle charge. right?
Anyone came across this yet?
I know that some people suggested the freezer trick, but I don't want to do that before I checked on this with the community members here.
Many thanks in advance for your assistance and sorry again if I missed a similar thread.

It could. The charger cable got 2 red wires thats connected to the same point on the TF.
One of the wires is your normal +5v USB power, while the other is connected to a USB3 pin to tell the charger to spit out 15V instead of 5V.
If that particular cable is broken, the charger will only send 5V.
The odds that that small wire is broken though, is... well, very slim.
Hi there!
I have a B80 Tablet which was working properly as it should, until on Wednesday I left it completely dry (both dock and tablet 0%) and now they won't charge at all!
The wall charger and cable were tested with my friends TF101 - working fine, no problems at all.
Also when I turned on in the evening it showed the Battery (with red status) icon which means it needs to be charged - I put it on the wal charger for 3 hours and the dock was not charged at all, and the tablet got 3% juice and that was it.
Neither the dock or tablet is charging - tried them separately
Also tried cold-boot, the "freezer trick", the USB trick - no success
Any suggestions? Experience?
Thanks!
P.S: 3.2.1 HC, KRAKD ROM, default kernel, no OC
Mine is doing something similar. Tablet will charge but keyboard won't. If I leave tablet connected to keyboard I will draining completely in less then 4 hours. I have the OG Transformer 101.
ICS (revolver tf101 4.0.0 RC1 with stock kernel)

Now I managed to get the tablet to 9% Via USB Port -.-
Also tested my friend's charger which works as well - but mine does not want to charge...
Ive got exactly the same problem with one exception, i am not able to charge it at all!! After all night connected to charget still 0% battery, in dual batter widget there is unknown battery error. Charger is ok. Dock is fully chargedand even from dock my tablet wont charge.
What is more i am not able to flash stock rom with nvflash, it disconnects after sending bootloader.
Do you have any ideas what to do now?

Just a few questions:
I plugged the dock on the wall charger without the tablet - it shows no life signs. Isn't the LED should be blinking? Also left the tablet on the wall charger for 2 hours and the battery was charged a bit (10%) - so it can't be the charger.
Also since it got a little charge - it can be hardware error with the battery. A loose cable?
Also managed to go back to stock ROM and no help - can it be that the cable has issues?
Battery voltage shows 7V BTW currently
Have you guys try using PC USB port alone and charge the tablet for like a day?
Put the tablet OFF and let it charge thru the day(12hrs) and see what happen.
Next, dock the tablet to it's keyboard and fire up. Go to settings - Developer options - USB debugging(uncheck).
Go to Settings - Asus customised setting - MobileDock Battery mode(uncheck).
Still docking, now restart the TF101.
And yes, the dock would blink when charging take place until it turn green when full charged..
Just tablet wouldn't charge
I have a similar same issue. It was working fine and then when i went to pick it up to use it wouldn't start up. So I followed all the tips i can find so far but no dice. Here are the rest of the info:
The unit will not turn on if I don't have the power cable plugged in.
1) When the cable is pulled out, the unit turns off and will not turn back on
2) When the cable is plugged in, it turns on and work just fine
3) When I put it on the keyboard dock, it turns on and work just fine
4) When I pull it out of the keyboard, it turns off and will not turn back on
5) I have soft reset, hard reset and factory reset (all with power plugged in) because nothing will happen without the power plugged in
6) Battery status shows 86% but not charging:
--When plugged into the wall
7) Battery status shows 86% but not charging while in the dock.
--The dock battery shows that it is charging and the light on the dock is green
I have tested and knows the charger works and the dock battery works.
The main unit battery will not deplete and will not charge.
What do I need to do?

Ive done exactly the same tests, and behaviour of my tablet is almost the same (battery 0%)
I am waiting for a responce from Asus.
Honestly speaking i am glad to hear that someone else has the same problems and the same symptoms. It means that the Asus hardware or ICS update messed something up.
Sent from my GT-I9000 using Tapatalk 2
I hope ASUS says something, becuase this is driving me crazy - out of the blue suddenly not working.
I charged the tablet via USB overnight - 46% right now, but the dock does not want to go up from 0%
And it looks like it charges via the wall charger as well, but it is the same as via USB - so the "real" charging is not triggered.
Fixed!!!
Looks like the wall charger charged with 5V, but not with 15V properly - which is utterly strange.
Waiting for a new replacement charger - with 12V 1A should be working.
BTW, if you want to do this, there are already threads.
You need a Molex Female and a USB Female cable - wire it like on the picture.
Yellow cable from Molex to USB red and the black cable from Molex (next to the red) to USB Black - that's it.
Great that it works for you but I don't think that is my problem though. I can't get it to trickle charge from the USB even. And the battery widget said "battery health = unknown error".
I guess I will still wait...

My charger is 100% good (tested on my friends tablet). Besides it should charge from dock but it doesnt!
Still waiting for asus responce.

GOOD NEWS! Tired this and keyboard showed 99%. I will need to run power down and try to charge later to see if fixed completely.
Now for what I did.
Took the base AC charger from my Galaxy Nexus, any base should work, then used the standard USB cable that came with the Transformer and plugged it into the AC charger and the keyboard dock without tablet attached. Plugged into the wall and got nothing. No lights or anything. Then switched back to the AC charger base that came with the Transformer. Plugged into wall and I got a green light on the keyboard dock so I then docked the tablet. The dual battery widget showed 17% tablet and 99% dock. At last check it was 27% tablet and 99% dock.
Hope this is a fix.

Hi davebugyi, so if I understand correctly, the solution is to use a 12V 1A USB charger to revive the battery of a dead dock? I have the issue as per my post here
Needless to say the dead dock battery is driving me mad!! Even opened up the dock and flipped the battery switch inside!!

Thanks so much for this. This just happened to me too and was tearing my hair out why it wouldn't charge. Done trickle usb charge for 5 min from my phone plug and then plugged normal charger in again and instead of 0% it was at 33% and is now charging again.
Hope This helps
I had this problem for so long, that i even gave up on looking for fixes.
the problem was that i remember dropping my adapter accidentally, so it became loose. but I didn't know this, I thought the cable was faulty. so simple fix...if your adaptor is loose, try fitting it in place.
sorry for my bad sentence structure and bad description, hope it helps
Hello guys, i am hoping that you can help me because i don't know where else to turn. I purchased a Verizon note pro 12.2. I was using it and on for about two weeks until i got my surface 3. Two days ago i went to use it and it wouldnt turn on. I assumed it was the battery so i put it on the original charger for about an hour and attempted to turn it on. It booted to the Verizon logo then flickered off. I put it back on the charger overnight thinking that would fix the problem. When i attempted to turn it back on it loaded to the Samsung splash screen and then turned off again. When i plugged in the charger once again the grey battery icon came up saying the battery was 100%. Even with the battery saying it was 100% it still wont turn past the splash screen. This only happens when it connect to the charger. it doesn't do anything at all if it is not plugged in. I have taken the battery out and reconnected it... still nothing. Looking at other post i assumed it was a software issue so i tried to sideload a stock version (Cant use odin because the tablet cant even boot into odin mode) of P905VVRUANK1 which is what the tablet was running. I got the error footer is wrong security authentication failure. I dont know what to do. Please help!!
correction i did not sideload (wrong terminology) i tried to flash through recovery mode.

Probably you have a loose or cracked battery connector. Try this, power on while pressing hard on the back near the center ( location of battery connector ). If it can boot this way, you need to re solder the battery connector.

I have seen this problem in many Tab Pro or Note Pro: it cannot turn on even with full battery. When battery connector's pins are open or cracked, your tablet won't be able to turn on. There are too many unknowns such as USB charging port, battery connector, or battery. You need this tool to find out where is the problem:
http://www.ebay.com/sch/i.html?_fro....TRS1&_nkw=usb+voltage+current+meter&_sacat=0
When charging, current should be 1.7 Amps.
It sounds silly but I see many users cannot figure out the problem which simply comes from bad USB cable or charger or USB charging port. This tool will eliminate guessing.
Since checking battery connector requires experiences to know the solder joints are good or bad. My recommendation for your problem: Re solder the battery connector if everything else: USB cable, charger, USB port, battery are in good working condition.
Use another battery you won't see the difference if battery connector on main board is cracked or loose.
Cracked battery connector is very common in this tablet but most average users won't see it or don't understand why it's the source of problem.

I do not believe that is the issue. the charger i used after the fact was a samsungng 5.3v charger thats belongs to the other note pro. im assuming if it was a issue with the amp that the other note pro would have the same issue... could it have something to do with the bootloader maybe.... or maybe theres a file i could flash that im just not aware of...

Beut was right all along...
OK, picked up a tf700t with the dock for next to nothing(30$) It has a slight issue.... the display doesn't work. Here is the issue. The tablet charges, holds a charge and functions fine... when plugged in to a PC. If it is not plugged into a PC, the display is dark. Touch screen works, HDMI works whether the tablet is connected to a PC or not. I am thinking it might be the power port as the Asus charging cable is very loose when plugged in. I have taken the tablet apart and nothing appears out of the ordinary. There is some scorch-like damage to the cable from the port to the mainboard.
I am stumped. I don't think it is the mainboard as the tablet boots just fine. I already have it unlocked, TWRP installed and running KK Nougat v13. Pics to prove my point
Tablet plugged into TV via HDMI, but not plugged into PC
Tablet plugged into PC and TV via HDMI
yes, I have searched and while many have posted the issue, I have not seen an answer to the issue. I am thinking if it isn't the power port, that it be the battery not putting out enough voltage. Any help or ideas would be greatly appreciated. Oh yeah, I have to wiggle the plug in the power port to get the screen to come on. That is what has me thinking that it might be something with the port
One more data point to add. Display works when the tablet is plugged into the wall charger.
Beginning to think that it may be the battery. It may be charging and holding a charge, but it may be discharging at a lower value than what the mainboard wants to see. Would this cause the display to turn off?
