Charging Issues - Eee Pad Transformer Q&A, Help & Troubleshooting

I was wondering if anyone else has this issue. Charging my Transformer has always been a little "hinky". Sometimes had to plug in, re-plug to get the charging notification on the screen. This was both with unrooted stock and stock rooted. No custom ROM or kernel. After the ICS update, plugging in the charger does not work at all unless the tablet completely re-boots. I learned this by doing the plug, unplug thing and the tablet re-booted on it's own and started charging. The next day I tried just plugging it in and did not charge until I manually rebooted. Just wondering if I'm alone in this problem or if anyone else has experienced this. Reading the threads I wonder how many people wake up to dead tablets because they never charged in the first place.

Mine has improved actually. Instant recognition of power being plugged in...whereas in HC sometimes...like you said...it took 10 seconds or plug and unplug to get the tablet to register that it needed to start charging.

No problem on my ICS. It's always instantly recognized like the guy above said.
Do factory reset and cold boot.
If rebooting fixes the issue like you said, it's probably because there is some incompatible app causing problems.

Phone Freezes While Charging

I had my phone freeze when charging, the screen would be of, when i would hit the power button the phone would not wake up, I would have to take the battery out to turn it back on, Any one else experiencing this? Its happen 3x to me already
I guess i am one of the lucky people i have yet to have any problems other then alittle bit of lcd bleeding. My phone is running great. I would tell you to keep an eye one it. If you bring it into a store will they need exchange it for u unless the problem is going on right the store. It could also just be something with android as well.
Probably bad grounding circuitry in the charger or phone.

I have had it happen twice, and once I found my phone stuck in boot loop forcing me to do a hard reset.
Just happened to me. Never happened to my G1 while charging in the same place
Sent from my LG-P999 using XDA Premium App
Its happened a total of 8 times for me (My 3rd day with the phone). First time I was late to work because the alarm didn't go off.
Always when I charge via a wall charger. Have tried the LG charger with LG usb cable, oem usb cable, blackberry charger. They all freeze my phone. I've noticed that every time it happens, my phone gets real hot, often times when i get a text in while its plugged in it freezes. The only way I can charge the phone without it freezing was through a usb port on my computer. Don't know if its an issue with the charger or the phone, but this is annoying
O and I've looked at the LG O2X forums too, it seems like they are having the same issues too, freezes and bleeds
It's happening to my "replacement" g2x. I have to pull out the battery to get it working again.

Could be a combined hardware/software problem with battery charging, which also explains the poor battery life many experience.
When charging via wall adapter I wouldnt doubt if it is going into thermal shutdown and the battery is getting too hot, pushing too many amps too quickly....usb connected to your computer fixes that issue since it cannot push that much current.
Sounding more and more like LG did something bad here.
I have never had this happen.
I use the included charger, a nook charger, and the charger for the HD7.
All have worked perfectly fine. I would definitely keep an eye on your heat.
I've had at least six reboots and a few of the black screen shutdowns where the battery has to be pulled.

Yea I think it really is heat related. Using battery monitor widget, I found that the last few times my phone froze up while charging, the temp was hovering above 35 celsius, seen it hit 39.8

Those temps aren't bad. I have seen up to 45c while charging and using wifi tether and I haven't got a force reset.

I had this exact issue; plugged in, got a text and it froze, requiring a battery pull. I also noticed it got really hot. Interestingly, I had received a bunch of texts prior just fine while plugged in. The last text I received was repeated three or four times and then I got a notification about what appears to be the SMS app hanging (I forget the exact package name but I know it had SMS or MMS in it).
I have had my g2x for about 3 days and this problem has occurred on mine about 3 times so far.
The first time it happened i pressed power button several times, also tried holding it down. After about a min of messing with it. i actually got the screen to light up with the lock screen by holding down power button and up volume. but once i let go of buttons screen blanked out again. i was unable to reproduce it again. so i pulled the battery.
Having the same issue here. I'm on my second G2x (exchanged the first one because of lcd bleeding). Had the phone for 2 days, and I've had 2 freezes with blank screen and one reboot while charging thus far.
Interestingly, both times I encountered the phone freeze with blank screen were when I've completely discharged the battery and the phone was off when I plugged in the charger. After I plugged in the charger, i turned on the phone, and about 20-30 minutes later, i'd get the blank screen phone freeze.
The other time my phone rebooted while charging was when I plugged in the charger with the phone at around 75% battery.
I think it's because of crappy charger or cable. I don't have difficalities at home with the original ones but in the office the touchscreen of my Motorolla Photon freezes.
Its the kernel. My Transformer will do the same thing on certain kernels. I haven't had it once while on MIUI and Faux, and I went through 2 phones.
LG G2x - 2.3.5 MIUI
Asus Transformer - 3.2 Revolver

It's dead Jim.

OK, never had any auto resets, just had to manually restart often to cure various ills. Then yesterday it was stuck on the dimmest backlight setting. This morning picked it up from charging overnight and it's 100% dead. Switched batteries, plugged it into various computers and USB power sources. Dead.
Anyone brought a G2x back to life?
Have you tried a wall charger? If your battery discharges completely, like deader than dead, then sometimes you have to plug it into a wall charger and leave it there for several minutes before the phone will even show its connected to a charger.
I guess the real question to ask first is, what did you have it plugged in to? What kind of charger? Was it plugged into a surge protector?
It was plugged into the LG wall charger it came with overnight. I tried a iGo USB wall -> USB power supply and a USB port on my desktop windows PC.

It depends on how dead it is, if its a hardware defect of some sort then you're probably SOL. But, you don't have to be able to turn it on per se to use NVFlash, so if I were you I would try to see if you can get the device to be recognized using the APX drivers. If you can, then you might have a chance.
My G2x died after freaking up during one of the Davlik cache clears....
It originally would boot up and get stuck at "LG", but after a while it was completely unresponsive (not even a Boot Logo) and wouldn't even turn on. I thought it was fried. Luckily we have NVFlash that you can use without booting the phone up.
Take the battery out and press and hold the VOL keys, then plug it in. Your PC should "ping" letting you know something was connected. Then just reflash a recovery.
I did this a ton of times and it didn't work at first. I kept flashing stock then CWM, then stock, then CWM (different versions too). Eventually it displayed the LG logo and allowed me to boot into CWM where I flashed a new rom.
Been solid ever since.
I also read about this in the Asus Transformer forums (cause I just picked one up) and read about a guy experiencing the same thing.
Worth a shot. The NVFlash method will at least let you know if it is DEAD or just not working. If NVFlash doesn't connect then it is hosed. If NVFlash connects and accepts a new recovery, then something just got corrupted.
All good now! I unplugged, removed battery, let sit a while. Put the battery back in and it booted! Yet more strange behaviour from the G2x, but as usually I get it working again and stick with this phone.
But today I got a second from craigslist to play with alternate ROMs. Trying CM7.1 RC1 first, it's working pretty good on my Nook.

[Q] Bricked --> Battery Drain

Hi all,
So my transformer is bricked... completely been trying hard reboot, APX mode, holding power button, HDMI output the list goes on.
My only final resort is what I've read is draining the battery down and trying to recharge it? (Just need some confirmation here please if possible).
I've kept it in the dock, what I've noticed is, in the morning it was green LED now its gone to the amber so something is draining the battery I"m hoping I can get this down to 0.
How long do you guys think with both dock + pad and most likely on standby. Not too sure of the issue here
Anyway, I'm really reluctant to send this back to Asus RMA because in short:
1. First time I sent it, it got returned like a squeaky box. Every where you held it you heard a creak like it was about to snap. They didn't fix some things, and more dust ended up in my camera lens... + had to pay postage..
2. Half fixed, came back with wrong firmware (TW --> US). Could never update ever again, so microsd card updates FTW. No way was I planning on spending an extra month sending my TF back and forth... I paid extra to get the first batch B40 lol.. They replaced everything inside my TF motherboard, screen, Inside LED!?, buttons. Close to the works..
This happened right after I upgraded to ICS, it was the US stock rom booted up fine. my apps were updating, and as everyone else was saying about how some apps caused ICS to slow down I wasn't aware so I thought I would shut it down and power it back up. Since then it's not been able to come up ever again... Any suggestions?
What do you think?
Thanks in advanced.
One other thing, could someone check.. when tablet is docked and OFF. Do the usb ports still work?
Right now, when docked but "bricked" I can still charge my phone via USB.. If someone could test this that would be much appreciated as that could at least eliminate that my TF's battery is dead, right?
get it off the dock, hold volup+pwr, count to six and leave it for a couple of days. You can test if it's empty when you plug it in your pc via the cable. If you get the device plugged sound it means there's still juice there - unplug and press again volup+pwr. when you unplug it from the pc the tab shuts itself down.
if you don't volup+pwr before you plug in the usb it won't turn itself on. but it turns off automatically at unplug, as I said.
after the battery is down, plug the tab to the charger. I don't have the dock so I can only speak about the tab itself. Don't know why, but it works for me everytime. Hope it fixes yours, then, if possible, root and flash something.

Hi there,
Thanks, I'll that a try.
It's definitely charging and discharging, the battery brick is warm.. I've never had to connect my tablet to a windows PC. Today I did, it didn't make a sound.. Do I need to fully charge to be able to turn it on?
Normally not. I plug mine to the charger, I don't remember if it stats or I have to press power, when it boots the battery stays at 0% for several minutes.
Sorry for the late reply, did you manage to wake it? It's a long procedure of waiting mainly and can get annoying.
I'm still trying, earlier you had a thread about it poping up through the computer. What was the command you used in Linux?
Windows gives me nothign even when there was power in it.
Thanks.
Thank you sooo much!! It finally has powered back on, I hope this doesn't happen again.

[Q] Shuts down completely when not charging

I posted this to another similar thread but they have solved their problem but mine is not solved.
A little background:
It was most recently upgraded to the the newest OTA and been stable since then. The unit is nearly 1 year old B50. So I know all about holding the power button down for different lengths for different purposes. It is NOT that. Until two days ago, everything was working fine.
First, I couldn't turn it on. I thought since I was travelling and using it a lot, it just ran the battery down. So when I got to the hotel room, I plugged it into the wall charger and it turned on. I was relieved for a while. Then I checked the battery (dual battery widget) and it shows 86%. When I was leaving the room, i pulled it off the wall and bam...it shuts down completely. Curious, I plugged in the charger and it boots back up (asus logo and whirling circle). I decided to leave it plugged in all night.
The next morning, I pulled it off the wall and bam, complete shut down. I plugged it back in and check the battery status. Still showing 86% and I notice it is not charging. I check the battery summary and it shows, battery = unknown error.
I did the hard reset (with it plugged in) VolDown/Power sequence. No luck. I decided to wait until i get home to test further.
At home, I plugged it into the dock. Widget shows the base battery is charging but the tablet is not charging. (it turns on when plugged into the base). It stays on even after I unplugged the base from the charger but the moment i remove the tablet from the base, it shuts of completely.
At that time, I decided to do a complete factory reset. After the reset, it is still having the same problem and dual battery widget is reporting the same unknown error problem.
In summary:
1) The unit will not turn on if I don't have the power cable plugged in.
2) When the cable is pulled out, the unit turns off and will not turn back on
3) When the cable is plugged in, it turns on and work just fine
4) When I put it on the keyboard dock, it turns on and work just fine
5) When I pull it out of the keyboard, it turns off and will not turn back on
6) I have soft reset, hard reset and factory reset (all with power plugged in) because nothing will happen without the power plugged in
7) Battery status shows 86% but not charging:
--When plugged into the wall
8) 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 and will not keep the unit running.
What do I need to do? Any thoughts? I would greatly appreciate some help.
Are you rooted? and did you try to clear the battery stats?
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
you can use that to clear your previous battery stats, and may help with getting a better reading on whats wrong. a messed up battery stat maybe messing with the charging process.
No, it is not rooted. I have just reset to factory settings again. But I might take that route soon if I don't hear from Asus. Is there an good detailed instructions for rooting my TF101?

http://forum.xda-developers.com/showthread.php?t=1366743
you can start there. i got rooted when it was in HC didnt like the stock feel, so went to Prime Rom( honeycomb builds) the dev kept it close to stock but with some tweaks to the kernel. was a bit afraid to root at first, but just read through the tutorials, and just did it.
anyways Good luck!!
OK, nothing else seems to work. So, I am trying to go down this rooting road and using the battery calliberation tool.
As I was reading through the instructions, I find the build version supported is much older than mine (9.2.1.21) so, unless i am reading something wrong, this will not work.
Anyone has any other thoughts? Thanks in advance.

[Q] Did I just brick my Evita One X?

I do apologize for filling up this forum with yet another "Did I brick..." question, but I'm really at my wits end and need some guidance.
This morning I decided to update my kernel to ElementalX 5.0. Prior to this I was using the 4.5b kernel and had no issues, but I wanted to move to the stable release and hadn't had any issues in the past. I have ViperXL 3.2.3 installed on this as well. I have yet to apply S-Off as I haven't had any real issues at the time and wanted to wait for the weekend when I had enough time to dedicate to the process (life is hectic blah blah blah).
I downloaded and installed the 5.0 kernel as I had previously, making a nandroid prior to the install. I decided to try some of the overclocks/undervolts that everyone raves about so during the install I chose the 2.1GHz overclock (because I can always step it down if it gets flaky, right?) as well as overclocking the GPU and undervolting to 850. I also went with zRAM as usual. After this was done and the phone rebooted twice (a common occurrence) I was brought to the window where Android was optimizing my apps. After that completed, I was brought to my home screen where I saw the clock and everything else. It looked like yet another successful install....and then the phone went black. Since then I have been unable to get it to boot. Pressing and holding the Power + Volume Down does nothing. I've held it for over a minute and no blinking capacitive lights or anything. The charge light does not come on when it's plugged in and, while my computer first tried to install the drivers when I plugged it in, I received an error saying the device was unplugged and no matter what I do I cannot get it to try to install again. Device Manager doesn't show it as being plugged in and it no longer comes up in Windows Explorer. Prior to the install the batter was at 83% and I have had it plugged in now for almost 20 minutes and still the charge light has not illuminated.
I never thought it would be possible to kill this phone, but I think I successfully did. Does anyone have any insight, suggestions, or helpful pointers. Yes, I know this was a risk I took doing this and I am not going to bemoan the fact that I did this to myself...I just really want to know if it's possible to resurrect this phone.

So do that as opposed to plugging it into a PC? Asking since I don't have a cube with me at the moment and will need to run home at lunch to grab one if the case.
Yes into the wall charger...and hold power for thirty seconds does anything light up?
As for my own experience I have had trouble getting my phone to reboot or get into the bootloader when it plugged in. The charger seems to keep the phone turned on while it charging. Try unplugging it from the charger and try again.
Sent from Xparent Red using my Venomized Evita
This happened to me too, but I got it to reboot by holding down the power button. What's happened is that the phone thinks the battery is dead. When it comes back up, you'll probably show 1% charge. Somehow or another, the battery monitor data gets corrupted. I think it's related to the general battery data bug that's plagued this phone from the beginning.
Your phone clearly can't handle 2.1 and undervolting (I increased my voltage to run 2.1). Bump up the voltage when you get it back up.

Definitely. The wall charger is much faster than USB from a computer.
IT LIVES!!!!
I ran home and grabbed my wall charger and brought it back to work. I plugged the phone into the charger and let it sit. After about 2 minutes, the charging LED lit up. I gave it about 15 minutes and then tried to power it on but it was no go, turning off the charging light and not doing anything, so I let it charge for another 30. When I thought it should be good and ready, I decided to go ahead and attempt to boot into the bootloader, as my fear was that the undervolt and massive overclock would most likely bring me back to square one. Holding down Power and Volume Down, I said a silent prayer to the device gods.....and the capacitive buttons began flashing.
Once I got into the bootloader, I quickly booted into TWRP, cleared cache and Dalvik, and then reinstalled ElementalX 5, this time choosing the stock voltage and not overclocking the GPU. I kept the overclock at 2.1 because, like I said before, if the phone is flaky, I can dial back the speed and restore functionality. I like the idea of having the option to go balls-to-the-walls if I WANT to, but not necessarily will I go that route.
After the lengthy kernel install and the normal 2 boots, I was met with my beautiful Viper lock screen. Thank you guys so much for the insight into needing to charge from the wall instead of the PC. I never imagined the computer would refuse provide a charge to it if it was completely dead (or the phone thought it was completely dead...once I got into TWRP it stated battery life was 86%). I am calibrating the battery now as I just realized it hasn't been done in probably 6 ROM installs.....derp!
Since this issue is resolved now, the thread can be closed. Thanks again, all!

USB charging might still work, it would just take a lot longer. Some folks have had to plug there wall charger for hours or overnight, even on the wall charger, to get their phone booted again. So the wall charger is just better since its faster.

And it may have, but the thing I noticed in the 90 or so minutes it was connected to my work PC was that the phone was the coldest it had ever been since I got it, meaning that the usual warmth caused by charging was not present at all. I did notice in Device Manager that when I plugged in the phone, it would register the phone as an HID (Human Input Device) and then it would disappear, only to reappear again and then disappear once more. This would happen non-stop until I disconnected it, so perhaps that's why it didn't charge at all during the time it was plugged into the computer? In any event, good ol' wall current supplied the juice necessary to bring this sucker back to life, so I'll file this info in my memory banks and make sure I have a wall charger at my desk from now on.
