Hello all,
I have a tablet TF101 B70 with what we think is a faulty battery which causes serious battery drain (charges up to 100% in a couple of minutes but discharges totally in 3-5 minutes as well).
Currently it's rooted, the recovery changed to TWRP and the ROM currently installed is EOS 4.2.2 I have a backup in the recovery of the previous stock ICS version by Asus.
I think I'll have to send it back to ASUS or the store I got it in for repair, and I would like to restore it to default values.
I know there are several guides here on how to do that but I need a method that allows me to keep the tablet connected to the wall charger, otherwise it might get bricked during the flashing period.
Thanks in advance for your responses

First of all; I've used search and found nothing that fitted my problem. I hope I didn't repeat a existing question.
My problem is this:
I have an european Galaxy S running on Darky's rom. Since a couple of days, I've been unable to charge the Galaxy through the USB port, a problem I never had in the past.
If plugged through the USB to a computer, the phone is properly detectd, and I can copy files into it without any problem. If I leave the cable plugged either there, a car adapter on my car, or a wall charger, the charging animation is on, but the battery drains slowly instead of charging.
What I've tried:
*tried different batteries
*updated to last Darky's rom (Slim no wipe)
*read about battery drain, recalibered battery; installing a fresh battery charged on an oem dock), wiping battery stats from CWM, leaving the phone on until battery slowly died
*full wipe, factory reset
*disable voodoo from cwm
*updated to last Darky's rom (full with wipe)
Nothing worked so far.
I have no clue of what is going on. I did nothing strange or new before this issue showed, at least as far as I remember. I'm running now swapping the depleted batteries out of the phone.
I hope somebody could help me.
Thank you.
If Darky broke it he should have the solution .
I would remove Darky rom and flash stock froyo .

I have flashed an older rom, I9000XXJP1, just for testing, and the problem is still there.
Could it be a hardware issue?.
Yeah we got one like this @ work, brand new and faulty.
The symptoms on the first day :
- Doesn't charge via PC or external power source
- USB mass storage is fine
- Still warm after at least one hour on idle (wifi, gps and bt OFF)
=> warranty.
I suggest that you put back the original ROM before it dies by lack of power and use your warranty
I think that's what I will have to do. I'll flash some old stock rom and send it to service. Pity I didn't keep the original one from Movistar network.
I'll look for it somewhere.
Thank you.
One question, was the screen on when you were doing this? I've noticed that the chargers usually don't have enough current to power the screen, the phone, and charge the battery all at once.
Hi everyone,
I was using the megatron 1.0.1 rom and I doubt it has anything to do with my problem, but did happen right after flashing this rom for the first time. I left the tablet docked in the keyboard dock in sleep mode for a few days only to come back to it completely drained. I don't think it was deep sleeping for some reason but I didn't look into it to much. I charged it back up through the keyboard dock, but now the battery widget is displaying 0% on the keyboard dock and will not charge it anymore. The light on the side always stays solid orange, never blinks and never goes green anymore. I have since changed to the latest ASUS official firmware in hopes to revive it with official firmware.
I tried a few suggestions with no luck. This is what I tried.
1. Reset battery stats and Cold reboot
2. Allow wake on keyboard, allow it to deep sleep and then wake it with keyboard press
3. Fully charge tablet with power adapter, turn off, change power adapter to keyboard dock and then reseat tablet and let it turn on automatically.
4. Leave it plugged in USB for a few hours.
5. Charge just the dock without the tablet seated.
I'm looking for any suggestions and hopefully someone who has solved the problem??
It is no longer under Warranty so RMA is not an option.
Thanks for any help.
Hi, i have the same problem. But i'm using Megatron 1.0.4 keyboard blinks orange all the time with the tablet docked and without it. I would also know if anyone have a solution for that. i didn'T tried to go to stok to see if it help.
The wake on Keypress is part of the ASUS official firmware and I saw a suggestion to try that to get the battery charging. Also I wanted to ensure I had the latest dock firmware incase ASUS put a fix in to revive the battery to start charging again. Does you battery widget also say 0%?
Blinking orange means below 5% I believe, and does the blinking orange stop when the tablet is not connected? If it blinks with the tablet disconnected from the keyboard dock, try contact cleaner of the dock connector, something might have shorted pins making it believe the tablet is connected.
Yes, my battery widget says 0%. Now i have tried the latest cornerstone nightley of teameos and my dock now stopped blinking and shows green. that means its full charged. but the widget shows 0%. now i try my nandroid backup of stock rom. in the teameos nightley i havent an option with wake on keypress
Thats good, sounds like you got your fixed. Our problems are a bit different with the status of the dock LED, but glad yours is fixed. I tried eos nightly 24 as well when I first tried to solve the problem, but it made no difference to addressing my problem.
And the wake on keyboard option is only in the ASUS based roms like the official or Revolution, Revolver, Frozn roms which are all based off the ASUS roms. Its in the ASUS option in settings.
Hoping someone will see this thread that might have a good suggestion.
Yes, i hope someone can help you out. my dock behaviour is now how it should be. green when fully charged, but the dual battery widget shows 0% for the dock. no wi try to restore my nandroid of stock rom and the first try failed with an error while restore the "/data"...i try it again after wipe everything. hope the widget will work on stock. But i will try again the megatron rom. Its the best i tried for now. TeamEos have some potential but Megatron is very fast and stable for me...with the only one problem with the dock battery
EDIT: Now it seems like i have fixed all. I have restored my nandroid of stock rom and then it worked with the widget correct. Now i install again the Megatron 1.0.4 Rom and voila it shows the battery icon and the dual battery widget how it should be. hope you will have succsess on your problem

Thats great, glad you've got it working right. So your solution was simply just flashing another rom and then back to stock and you were fixed?
I'm noticing another problem now, and not sure if it is at all to do with this. I was at 40% battery in my tablet last night. I turned it off, and I left it in the keyboard dock. When I woke up this morning and tried to turn in on, it wouldn't turn on. Plug it back in the outlet and let it turn on and it is 0% So somehow its still draining really quickly while being off. I need to test without the keyboard dock attached to see if it is some how sucking the battery out of the tablet. It now does the reverse of what its suppose to do, instead of giving power, it takes power from the tablet.
Weird issues, I might call ASUS and find out what it costs to repair this vs just buying another. Not having much luck on the forums with anyone else having this exact issue.
The quick battery drain is called a "Sleep of Death, or SOD" it's an ICS issue, nothing we can do untill ASUS fixes the firmware, as for the dock, try discharging the tablet completely then charging the dock and seeing if it will then charge the tablet. If so it's probably an indicator light/widget issue, flashing back to stock then back to ROM should fix it. Also check your connectors for debris/etc.. as suggested above.
Well good news for me, I called ASUS last night about the problem and the opened an RMA and told me to send it in. I wasn't going to mention the warranty already expired, and they didn't say anything when I gave them my serial number, so it was defiantly worth the effort. I will report back once I receive the dock, but to anyone that has a similar issue that can't be solved like mine, its worth the call to ASUS to see if they will still cover it. I think mine is more hardware problem then a software glitch.
Well just to end this thread and marked it as solved, I just wanted to comment that the only fix for mine was RMA. It seemed like a hardware problem, but perhaps just a coincidence that I also installed Megatron Rom just before. Anyways, if you find yourself in my situation, try ASUS RMA dept. I was out of warranty, they either didn't know or didn't care and RMA'd it for me. Thanks ASUS for the new keyboard dock, works perfectly again!
Hello all, my belove it Asus Eee pad transfomer is experiencing some battery issues. It has not been two months since I had this tablet and the battery wont charge and the tablet will not turn on with power cord plug into the outlet. I flashed the ROM with 4.1 later with Rom 4.2.1
My question is if it could be a bug with the ROM? How can i tell if its a rom issue or tha battery. Also, can defaulting it back to factory settings fix this???
Hello community,
i have a little bit of trouble with my shiny tablet and i would value your opinion;
Lately i noticed that when my tablet (outside of the dock) reaches a battery percentage of 67% the tablet just dies.
It shuts down and won't power on until i connect it either to the dock or to a wall outlet to let it charge.
I'm fairly sure by now that the culprit is the battery inside the tablet.
So this morning i called ASUS to check about warranty repair and all that fun stuff. (bought the tablet last august)
First thing the guy on the phone told me was: "you have an unlocked bootloader, if you want it fixed, you gotta pay for it!"
Offcourse i was pissed off becouse this is a hardware issue and not software related.
But hey! i'm just a simple consumer so what would i know (i believe this is what asus thinks )
so now i have a couple of options;
1) i send my tablet to asus for repairs. costs are about 75 euro's for initial handeling + costs for replacement part, say another 75 euro. that's a total repair bill of 150 euro's
2) order a new battery on ebay for 50 euro's and replace the battery myself, risking to damage the tablet even further. (i'm a server-administrator and fairly handy with hardware and all but i'm a little icky when it comes to compact delicate tablet hardware-stuff)
Does anyone know of a diagnostics utility that can read the complete battery? (e.g. check if all cells are correct and all)
Is there a hidden ASUS service menu or something? (like on smartphones)
And, if i send the tablet back to asus, should i remove all the custom rom-related stuff from the tablet and restore the factory asus software?
e.g. download original rom/recovery and flash those back (still gotta search for the how-to's and all)
ATM i'm running the latest CROMI (stock ASUS kernel) with TWRP recovery.
I look forward on the input from you guys!
Hello, i had the same problem.
Try this:
- Charge the tablet to 100%
- Turn off the tablet (a couple of hours or overnight)
- Turn it on and it should show the correct battery percentage, then you will have to charge the remaining battery.
well, i eventually put the tablet back to stock and this solved the problem.
after some thorough stress testing i got the battery down to 50% and it still works!
gonna flash a custom rom tonight again (cromi) and see if the problem is still there.
maybe it was the recovery, i was on TWRP 2.3.3 and now i'm on the latest TWRP 2.4
Hi guys,
Had a very weird issue yesterday with my Rogers S4. I have flashed a bunch of ROMS in the past, but wanted to try the new MEA firmware based ROMS..
Well yesterday i tried Mint Jelly v2.1 (flashed via TWRP) and immediately without rebooting flashed 005 FAUX kernal to avoid boot loops. My battery was about 15% at the time. The flash took, and the phone rebooted into the ROM no issues.
Noticed that when i plugged in the charger to my S4 it was NO LONGER charging. I tried multiple 2.1amp chargers, and cables, including OEM, and it no longer charged. However it charged my NOTE2 with no issues.
This is when i was about to FREAK.. but i recall from my HP Touchpad days that sometimes if the battery dies, you need to do something special to get hte phone to charge back up again.
So what i did, was completely shut down the phone, and plug it back in the charger, and it started to charge again. But immediately booting into Android, it would still no longer charge!!.. So i let it charge up for an hour wiht the power off. Once i booted in again, the phone was able to charge again normally with all my chargers while booted in.
I thought my situation was a freak incident until i noticed another XDA member report the same issue. This is NOT a hardware issue, but something related to software.. So give my advice a shot incase you encounter this yourselves!

Never flash anything or make major changes to your phone with a low battery (below 70%).
I may be the member he was talking about. I had a thread on this. Only difference was my phone wouldn't charge at all. When I plugged it in when it was off it would boot loop the charge screen. It was rooted and I had some bloat frozen, but the issue started after I installed Sugarsync. I had the same configuration for a few days with no problems, and my battery was about 50 percent when I tried to charge.

It's definitely possible and usually will work just fine. There are a couple of reasons to flash on a full battery. If something goes wrong and takes a lot longer than originally anticipated, there is less chance of the battery going dead while things are being fixed. Plus, many ROMs (Kernels actually) enact different power profiles for different stages of charge. If this is the case, flashing might not go as anticipated.

I bricked a S2 like that. Flashed a rom adn the battery drained in the process, causing it not flash properly. phone was dead, no download mode or anything.
