[Q] Battery indicator always showing question marker, level at 0% all the time

Hi, I just received my Transformer yesterday, and I'm having a great time using it. However, it seems i have a show stopping problem. When i first took it out of the box and powered it up, the battery indicator in the lower right showed some charge; when I touched it to bring up the expanded view, it showed the battery as being at 39%. I had an update available, but it wouldn't let me install it without being at 50% so I plugged in the charger. The battery level percentage kept going up until around 49%, then when I would pick up the transformer to check, all I would see is the battery icon with a question mark in it at the bottom right, and when I bring up the expanded view it showed the battery level at 0%. I was able to install the update by putting it into airplane mode and then putting it back into regular mode, somehow the battery meter went true and allowed me to install the update. However, I'm back to the previous problem and the airplane mode trick isn't working. The transformer KNOWS when the charger is attached, because when I remove it, it says "please connect your charger" because it thinks the battery level is at 0%, then I connect the charger and the message goes away. I also check the battery usage graph and it shows that it's being charged. I also used it for a couple of hours last night off the charger and I had no problems. I need to know if this is a software issue(fixable with an update) or a hardware issue(where I need to send in for a replacement). Any help is appreciated, thank you.

First, paragraphs.
It certainly sounds like something is amiss. But before contacting Asus or your retailer I would power it all the way off (hold the power button until the power off screen appears) and charge it for 8 solid hours as per the instructions. The power control circuitry may need that full charge to determine what is fully charged and set the appropriate values in the firmware.

I'll give that a show tonight and see what happens. Anyone else face this problem, or has heard of it?

I am having the same issue, battery meter has a question mark on it and it does not show the real battery strength.

Best solution is plug in immediately after removing from box to fully charge battery. I would plug in, turn it off and let it charge for 6-8 hours then do a reset.

Thanks, tried it but still the Battery Meter has question mark on it...

if battery was not charged enough, it may have mis flashed the update. Flashing a fw update requires a considerable amount of power. might get update follow directions to add to memory and manually install

Didn't understand this part...
Also another issue is that it does not detect my Dock, however when its docked and the dock is connected tp PC, i can access the files on Transformer.
I have even flashed with Prime 1.4 using the nvflash released by Rayman but still the battery icon has question mark on it.

I have these same issues......but my Transformer was working fine for ~1 month before it started. Did OP find a solution?

Bump
I just got this a couple of days ago. I was using the tablet as normal, when it suddenly turned off (like if someone cut the power).
I thought the screen turned off, but could not turn it back on.
Tried to hook it up to the dock, but only showed red battery logo then.
When hooking up to computers USB port, nothing is registered. When trying to turn on the tablet while connected to computer, the screen flashes ever so quickly like it doesn't get enough power to turn on.
If I hook it up to the power charger, it turns on fine, but only shows the questionmark in the battery icon. Status for battery in settings is "Unknown" and 0% (alternating between discharging and charging).
When hooking the dock up to wallcharger, it shows the green light (95% charged). The wallcharger obviously works, think it's the trasformer that crapped out.
Any ideas? Haven't tried the hard-reset or cold-boot yet (power + down for 10 secs) will do when I get home today. Who knows, I might be lucky

I fixed it by letting it die then recharging it completely (without use)

[Q]Tablet will only work when plugged into charger

So there is another thread sort of like this a bit below this one, but it's not quite the same situation, so I figured I'd make my own thread. My gf's tf101 has been working fine for the last couple of months, and then a couple of days ago, she found that as soon as she unplugged the tablet, it would shut off instantly. Once it's plugged back into the charger, it will boot and work fine. But, it will only work at all when plugged into the charger. When removed, no matter how long you hold the power button down, it won't turn on. I tried plugging it into the computer, and when I press the power button, it will flash the boot screen for about half a second, and then dies again. Keeps doing that, and will not stay on. Any suggestions, before an RMA? Anything to try?
Thanks.

What is the battery level showing when it is plugged in and on? Also check it with the Dual Battery Widget to see what that reports for battery charge/
I would back up all the data and apps, back up any important files and try a factory data reset. If that does not help, I would send it in for repair.

Ok, I was thinking about trying a factory reset next. The tablet shows 99% battery life left.

[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.

Leave it plugged in to a wall charger for a while

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.

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.

[Q] Tablet doesn't charge, dock does - what to replace?

I've been enjoying my TF300 since the month it was released, but in the past few months the battery stats have become less and less accurate. I was watching YouTube videos on it while it was docked and charging yesterday when it suddenly died, and I haven't been able to get it to boot since. Sometimes it will start to boot, but die half way through the boot animation, which implies that the battery isn't charging.
When I plug the charger directly into the tablet, it flashes orange twice and then does nothing. When I plug the charger into the dock, that shows green - so I assume the dock is fully charged. When I plug the tablet into the dock, it flashes red twice again.
The logical assumption from this is that my TF300 has stopped accepting or holding a charge. My question is, which part do you think I should try and replace first? I understand that the dock connector has separate pins for 5V and 15V charging, so maybe that's been bent or broken somehow...or the battery itself could be worn out...or the motherboard could have developed a fault. Has anyone had a similar experience to this? I don't want to buy a new tablet as there is absolutely nothing wrong with my beloved Transformer other than this!
I'm going to leave it plugged directly into a standard PC USB port for several hours tomorrow while i'm at work, to see if it will trickle charge that way. That would imply the charger is at fault, despite the green light from the dock when it's plugged in.

sort of same here
My thoughts are that the one battery is no longer seen by the tablet and the other is getting too much of a workout as a result.
We have possibly just lasted beyond it's expected lifetime - which is kind of dissappointing. I don't understand exactly, but we might troubleshoot this still.What rom or Firmware are you using? I am on straight CM11 with no other modifications. I am using the tablet docked al th time and th rom "sees" the two batteries but dies at about 50% of the one without touching the other. I'm pretty sure that it really only is using the dock battery and never seems to go to the tablet battery anymore. Wish I could fix it - will try to use it without the dock and see what happens.

It was running KatKiss 5.0.0 - I kept reminding myself to go and download the latest update but never got around to it.
After leaving it plugged into a standard 800mA charger all night and all day, it booted for about 20 seconds and then died again before it reached the lockscreen. It seems that the battery is either charging unusably slowly or not at all. I may have to start hunting for a new convertible!

Well mine is working fine disconnected from the dock - so it sees the Tablet battery and uses it now; I will use it until it needs charging and then try again - by attaching the dock and charging etc. Will yours work if just plugged in? - like a laptop with an old battery, does it still work but you are tied now to the power supply / charging cable? I have installed the latest "homebrew" Omni now to just get a new start on things and will continue to just use up the battery and see what happens next. My preference is to have vanilla CM but it seems the tablet battery was invisible. I hope by re-setting things and having a new Rom in place will give me a clean slate.

Sadly no, it doesn't run even when permanently tethered to the power supply. I think the battery has to report a minimum state of charge before it's allowed to turn on, and that's where it's failing in my case.

Batteries are back
I wish that I could tell you how - but I can't - the batteries are back to full functionality. I will tell what I have done and this might possibly help. I installed Omnirom with Lollipop and it worked but was very slow. Then I installed CM 11 back (then CM 12, then CM 11 again all with the appropriate GApps & SuperSU etc.) and it seemed to put things back in order. I did also install a battery calibration app which just deleted a file tracking the battery(s). Some where in there the batteries starting working properly - this involved more than a few re-boots and re-installs (dirty and clean). In all this mess lies a possible solution or maybe it was when I slammed it shut in frustration - this could all be due to a loose wire/solder joint too. The battery is following the "normal" process now of first draining the tablet battery to ~ 80-90%, switching out to the dock battery, then switching back to the tablet when the dock is drained fully.

@kjwaugh
I can't recharge my battery and I have CM-11-20150112.
My little led never turn on orange light.
My question for you is: Does your led turn on when you plug in the USB cable ?
I'm afraid I have broken some analog circuit inside the tablet or, I hope, only the cable.
Please let me know.

Battery completely dead or other hardware issue? [semi-resolved]

Hi All, my wifes s6 (using xtrestolite rom) has stopped taking a charge. Im trying to figure out what the issue is. Unfortunately im travelling for the next month so have limited trouble shooting options.
Background
- wife has been complaining that her phone battery dies quickly. I kind of dimissed her assuming it was in her head. she said it loses 10percent in standby mode in 1hr roughly. Shes been complaining about this for a week.
- yesterday at the airport her battery was at 12% and when we plugged it in to charge it wouldnt take a charge. Bolt icon did not come up and still said "connect charger" on the screen. Normally when connected the red Led comes on, but now it doesnt.
-our normal chsrging method is using and aukey 3port charger as fast charging mode.
Troubleshooting/diagnosis
- i have an s6 as well so i tested all the cables and chargers on my phone and it works. We even had the official samsung charger and cable but same issue.
- after the phone was completely dead, if you plug in the charging cable the charging bolt icon comes on for a few sec, the top left says "kernel is on seandroid enforcing" for a sec and then everything goes blank. Red charging led doesnt come on. So it seems like it detects the cable but wont charge enough to boot up.
- i was able to boot into twrp recovery but where its supposed to have a battery level its completely blank. Originally i was able to do this without any canles but then it wouldnt. My guess is that i orginally had a bit of juice and then it was completely dead.
-after leaving it plugged in for a sec, im able to turn it on where it boots and i can see it says 0% battery. It stays on for 5sec before turning off itself.
- i also tried plugging it into laptop, but laptop does not detect it. The phone does detect the power though and does the same as above but this time bolt charging icon stayes on for 1-2min before going off and seeing the "kernel is on seandroid icon". Once the seanadroid goes away nothing seems to happen. After doing this i was able to turn it on and it showed 1%. I thought this was promising but after trying this a few times ive never been able to get to 1percent again.
- with the brief charge thst i guess its getting, i was able to go i to twrp recovery and do a factory reset. This was with cable plugged in the whole time. Without cable in i dont think it would complete the action.
That about summarizes whats happened.
Ive concluded the following:
- charger and cables are ok and not the issue
- it is not the charging port since the phone does seem to be getting some juice bacause charging icon comes on for 2sec whenever cable is plugged in.
- its not a software/app issue since it wont charge even in recovery mode. Also factory reset was done and no luck.
My best guess is that the battery can only hold a 0-1% charge which is enough to register it being plugged in but not enough to do anything else. But if everything else is ok shouldnt it work when if the cable is just left in. This makes me think theres something else going on.
Any suggestions or theories would be much appreciated trying to decide if i should pay to get battery replaced.
Sorry for the long post. Figured it is best to give all info.
Thanks in advance!
Update June 3:
Hey everyone, just a correction on the above. It looks like it is able to charge in recovery (slowly). I realized that although there is no battery level during recovery, no charging led, and not booting up after being charged for a bit, maybe its just going slowly.
So i went into recovery and left it overnight on the non-fast charging and woke up after 8hrs and it was at 78percent!!!
Im not sure why it didnt go to 100% in 8hrs.
The phone still doesnt charge regularly when plugged in, so still need to fix that.
Do you guys think its a rom issue (only factory reset done before) ? I will see if i can get a rom for flashing.
Update 2:
Reflashed xtrestolite rom but still no luck. It wont charge.

Seems like a dead battery.

Bump.
Went to the phone store and they said its probably not the battery but the ic chip for charging? This will cost 150, but doesnt include the screen if they break it...
Does this make sense since i can charge in recovery.
Thanks. Any direction or input is much appreciated.

Go on the local store and change your battery (if isn't in warranty)

Hi all, just wanted to update the post that the issue is semi-fixed.
I brought it into a repair shop who offered to diagnose the problem for free before paying to replace the battery.
He told me there was nothing wrong with it and not sure what my issue was. Plugs in the charger and lo and behold it was charging. He said he didnt do anytning to it except blow some compressed air on the port.
Im guessing the comporessed air cleaned out a short? So now it charges properly.
The issue remaining is that the pc doesnt detect the phone. It shows as charging on the phone but no conmection. Tried to install the latest samung driver (1.5.4xxx?) but no luck. On occation sometimes it says "usb port has malfunctioned" but other times nothing.
My s6 does actually connect, so definitely my wife's s6 itself and not comp. Im tempted to buy some comlressed air and give it ankther blow, but dont want to risk messing it up again. im pretty happy that it at least charges up.
Hope this helps others that might have similar issue.
