[Q] power down bug?

hey guys.
i just want to know if you guys can replicate a problem i found and see if the problem i have is isolated or not.
so i've been charging my phone today and noticed that when i try and power down the phone while it is charging, the phone hangs at the shutdown circle and freezes.
when i unplug the charger (wall charger), then the phone immediately turns off.
at first i thought it was because of low battery ( i ran the phone until it died).
then i thought it was because i had no wireless connection (was in building-no signal).
when there was enough juice, i shut down the phone (not charging this time) and the phone powers down.
if this has been already covered, i apologize...
sorry for the bad grammar/punctuations. im feeling lazy. lol

defective NS?

My phone powers down while plugged in just fine. I just checked for you.
It takes about 30 seconds of the spinning shutting down message, then the screen switches to the battery charge icon for a few seconds, then the screen goes black.
A quick press (don't hold) of the power button brings back the battery charge icon for another 10 seconds or so.

Thanks for the reply. What is weird is that I tried the test at my local best and their demo phone was exhibiting the same thing. Maybe I'm not letting it shut down long enough.

okay, i've powered down again while charging. stuck on power down screen.
been over 2 min.
looks like i'm replacing this today.
anyone else want to chime in on this?

Since you're going to have to do a factory wipe/reset for privacy/security to exchange the phone anyways, can I suggest that before you assume the phone is bad that you perform a factory reset on it and then test again?
For all we know, you've got some rogue app that is causing the problem. I'd hate to see the NS returned as bad hardware when it might possibly just be bad software you've installed...

exactly what i plan on doing. gonna do a factory reset first.
But i think it will still happen because the demo unit at bestbuy was a clean install with no apps on there.
But i will update as soon as i restore!
thanks distorted!

wanted to add that when i shut down the phone while it was usb connected to the comp, it shut down properly and i saw your battery icon you were mentioning.
edit:
now i tried other wall plugs, usb cords and such and it all shuts down.
very weird.
It looks like it was the micro usb charger that i was using that was the problem.
I was using one that came with my blutooth charger.
I double checked all the information of the BT plug and compared with the ones that worked. the bluetooth cable was rated a .7 amps (just like the one that came with the nexus s). other cables were rated at 1 amp (which shut down the phone fine).
oi! saved me the trip to best buy.
i tested before and after factory reset.
all good except for the BT charger.

I can confirm that this is an issue. I have a spare micro-usb cable, and when I connect that to the computer, it charges fine, but the usb-debugging or usb-drive options never appear.
While it's in this state, and I go to shut down, the Power off - Shutting Down... screen will in fact freeze until the USB cable is unplugged. It does not do this with the stock usb cable.
When this "bad" cable is used with the stock wall charger, the same thing happens.

Hmmm... I wonder what can be causing this. Anyone else have this happening?

My best guess is that maybe there's something different with the pins and they are shorting/not aligned right in some cables.

[Q] Dock will not charge

My TF pad charges just fine, so there is not any problem with the charger. However, the dock does not charge at all. Even after 12 hours plugged into the wall with the unit turned off, the orange light is still flashing when I boot up. This might be a problem with the firmware. I am running:
HRI66.US_epad-8.2.3.13-20110511
I read somewhere that I should reflash the firmware. I have downloaded this version of the firmware onto a USB drive and the TF recognizes it but will not open the zip file.
What are the steps required to reinstall this firmware? Does anyone know of any other ways to fix the charging problem? The ASUS support site is nearly worthless. I humbly apologize in advance for my ignorance and thank anyone who responds.

that is the Build Number, and mine is the same and I updated everything correctly so it looks like you have the most updated version.
My MobileDock version is EP101-0209
It might be an issue with the dock charger, a hardware issue, the battery may have stopped working, we never know...
if it's a firmware issue, give Asus CS a call and ask them what to do next or how to properly install it.

Does anyone have any other suggestions? My keyboard has stopped charging as well.

Same for me unfortunately

I had the same issue and had to unplug and wait, switched outlets and it's fine now.
There is definetely something wrong.

Maybe it's designed to fully charge the tablet first then start topping off the dock.

I had the same issue - constant flashing orange led no matter what configuration I tried.. TF docked, TF not docked, TF docked powered on, TF docked power off, change outlets, let it sit for hours and hours (over 24 at one point) etc etc
Nothing worked.
And like yours, my TF always charged - whether docked or not.
Called Asus - w/o even asking any questions they just directed me to the RMA dept.
Instead I just returned it to Amazon and then waited until I could order another one. It took nearly a week, but they finally came back in stock on Amazon (for an hour) and I ordered another.
It should be here Wednesday, so by then I'll know FOR SURE whether it was the first dock that was bad - or if it's my charger / cable.
I'll post back once the new one gets here..

My keyboard is waiting for UPS pickup for a Newegg RMA. The keyboard is deactivated at Newegg now. I'm wondering if they will wait for more stock or give me a refund. I'm just glad I still have the tablet.
Does anyone know how widespread the dock charging problem is, and if newer units have any changes to fix this?

The docks were scarce here in Taiwan, still are. That must be an indication something is rotten in Denmark and Asus knows and are working on it.

Updating from my earlier post: My new keyboard / dock arrived yesterday. When I plugged it in, the LED was solid orange (ironically, this LED looks a lot more "red" whereas on my other dock it was definitely "orange").
I charged it for 8 hours and the LED turned green during the charging time.
So at this point I can definitely say that it was the dock that went bad and would not charge - as opposed to the charger being bad.
I would advise just returning your dock to the place of purchase if it's no longer charging.

Be interesting to see if those having charging problems with the dock have an orange or red led. I have had no issues, but my led definitely looks red. When the charger is charging, it gets very warm (hot). If your dock has been plugged into the charger for more than 20 mins and the charger is not very warm, it probably isn't charging.

Just wanted to update my previous post (2 up) because now my second dock is dead.
Under normal usage everything would worked fine - the battery would drain and then charge - no problems at all.
HOWEVER - There appears to be BIG problem with these docks and I feel this is what is causing (or contributing to) my docks dying. These things have a constant drain on them when the Transformer tablet is attached - even if you power the tablet OFF.
http://forum.xda-developers.com/showthread.php?t=1112835
I believe what is happening in my case is that the dock battery drains to a point where it will no longer accept a charge. In both cases, I had the tablet docked to the keyboard - powered OFF - and did not use it for a week or so. When I went to power it on, the tablet/dock had just enough juice to tell me that the battery was very low (I believe around 1%) and that it needed to be charged - and then it shut down.
OK, fine, no problem. I plugged it in to charge and left it.
The tablet charged up to 100% with no issues, however 72 hours later and again I have a keyboard dock with a constant blinking orange LED that will not charge. Again, I tried charging it with the tablet attached and without - no change. The adapter doesn't even heat up when trying to charge which again tells me that something in the battery on the dock is not accepting the charge.
Looks like this one will be going back to Amazon as well. I'll also contact Asus regarding the issue and will report back what I hear.

Hello,
I Have the same behaviour,everything were fine until I unplug the dock during several days and the charge was down at 0%.
Now, I 'm unable to charge the dock with or without the tablet plugged
I hope that it's only a firmware issue.....................

Sorry to hear it, but thanks for letting us know.
I have a bad feeling that this is an issue that is going to end up biting MANY users after their return period has expired. It seems that the huge majority of TF owners use their tablets / docks nearly every day - if not daily - so they won't run into this problem.
I'm concerned that after a month or so and some of the excitement has worn off, and they put their TF/dock away for several days suddenly their dock will be rendered useless (at least as far as the extra battery goes).
I've just sent a note off to Asus (per their request from my Amazon review) and I'll let you know what I hear back.

OK
thanks you for your action !! and to keep us informed.
For me, a lot of people are concerned ..... as you said...

i have same question too

My dock has same problem, have tried with or without tablet recharging, the led of dock is always blinking red when tablet connected, and dual battery widiget always display it's discharging and slow draining from 40% to 35% now.

In order to consolidate and try to keep this issue in one thread, I'll only be updating this thread going forward: http://forum.xda-developers.com/showthread.php?t=1112835
I just added my latest correspondence with Asus on the matter, but unfortunately it doesn't look like I'm really getting through to anyone of quality over there..

gents,
just wanted to add my possible fix for this issue.
I had this probem and my dock would not charge. Somehow i got it working again. Here are the steps i took, not sure what fixed it in the end but you could try and replicate and see how you get on.
1. I went to charge my keyboard on its own. I left it charging for hours and it was still flashing red.
2. docked the keyboard and the power widgets showed no juice within the dock althought it worked as a keyboard.
3. I plugged the power in the dock while docked and on. It showed that it was charging the tablet but not the dock. The dock stayed at 0%.
4. I left the two charging while on for a few hours. The tablet was now showing as charged but nothing still in the dock. I then shut down the device with a turn off but left the power and the dock in. As i shut down the light on the side went to solid red and stayed solid red while the device was off.
5. I left the device off but with the charger in the docked keyboard for about 10 minutes. I then turned the device on while docked and still charging. When the device turned on the battery widgets showed the dock with 35% charge. i left the device alone for a while on and dokced and charging and after about 10 minutes the dock charge started going up. I left the dock charge while the on the tablet was on and docked until the dock was charged to 100%. I then turned the tablet off. took the charger out and undocked. Turned the tablet on while on its own. Then docked it with the dock with no charger in and da daaar the keyboard showed 100% charge and was working......yea!

This is what I figured out, not sure if it's actually true but whenever I did some huge data transfer from the datacable computer --> tablet afterwards it wouldn't charge... so I had to leave it unplugged for over 6 hours adapater and cable, then tried again and it works... still going to go visit the local asus warranty center sigh.

[Q] Charging oddities while phone is off

Hi,
Last year my girlfriend allowed me to root her Sensation to try out different ROMs and all went well. A few months ago however, she started to have problems while charging her phone.
If she plugs it in while the phone is closed, the orange LED flashes on/off at around a 2 second interval, instead of holding it's colour. Furthermore, it never changes to green to indicate that the charge is complete. When the phone is in this state, she can't turn her phone on either - she has to unplug it in order to turn it on. If the phone is already on, and she plugs it in, everything behaves normally.
Either than that, the battery seems to hold the charge normally and the rest of the phone still works very well.
I've tried searching for similar problems but haven't landed on anything similar or which may be helpful. It's really got me stumped to what could be the cause, and more importantly, how to fix it!
Would someone have any ideas?
Thanks!

Does the phone behaves in same manner if it's fully charge n switched off when plugged to the charger.does the orange led fluctuate.
The orange led fluctuate whn the voltage of charger is less and it takes times to charge try switching the charger means if you use wall charger then charge through pc and vice versa
Hit thanks button if you find me helpfully

We tried switching from wall plug to USB on the laptop and it does the same thing. However, we noticed that if the battery isn't completely drained, the led doesn't flash - it charges normally.
Would there be a way around this?

I'd pick on the odds that the LED light hardware controller is slightly faulty, but if its really like you said its nothing to worry about, right?

Hi,
greetings
this used to happen with me when i was on stock rom.
the problem is when the battery is completely drained it needs lots of voltage to get charge
for this problem i took my cell to htc service center and they replaced the adapter and the problem was solved
i think you must buy a new adapter or say a new charger i thing that must solve your problem of led and your phone will get charge as normal even with the battery completely drained OR i think we get wall chargers you can look at the picture in which we have to place the battery and the battery gets charged you justt have to put the battery.. this charger is locally available in indian market for 80 to 100 rs.. you can search on net for the charger this is really a good thing and is a universal charger chagers each and every battery here in india we call it as khekda (marathi word for carb ) charger
let me know if it does solve your battery

[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.

K1 tablet screen turns on randomly

I posted this in the geforce forums as well with no response so I'm trying here. Original post: https://forums.geforce.com/default/topic/903373/k1-tablet-screen-turns-on-randomly
I haven't had this tablet for longer than a week now. When it's charging the screen turns on randomly. There will be no notifications or anything on the screen. It keeps happening when it's charging and i have no idea why. I don' t have a case yet so it has woken me up a few times over the night from lighting up my room whenever the screen turns on.
This doesn't seem like normal behavior to me.. has anyone had this happen to them? Should I be concerned and try to get a new one?

Has anyone fixed the problem?
Thanks

Do you have locked bootloader and a custom ROM installed?

Nope, everything is stock..

Then I don't know man...
The same happens to me with every custom ROM in my locked bootloader tablet. With stock it behaves normal, so I concluded that somehow it has to be something related to bootloader or something.
But re-reading you again, it isnt the same thing. In my case, The whole tablet turns on after being off when charging. Not The screen only. If I were you, I would do a factory reset and would see if it does The same thing with no other apps installed.

I have this happen using both the stock kernel and the BitO kx 060 kernel, but only when charging from my laptop usb. Using ampere to monitor battery charging I notice that my laptop's output fluctuates up and down, sometimes down to zero. For me I'm assuming it turns on when it either stops getting a charge, or resumes charging. I do not have this problem using a wall charger, but i am using a 5v 2a charger. Hope this is of some help pointing you in the right direction.

ooohhh.. that's a good idea. Thanks! I'll have to try another power source when I get home. I'll try that and will update the thread with my findings.

Hey, just thought I'd ask if you ever found a solution to this? It's happening to me, too: brand new, entirely unmodified K1, straight from the shop. While charging, the screen keeps turning on and off, which is not only mildly annoying but probably makes the charging take a lot longer than it needs to.

That's actually normal for Android devices. If the screen is off and you plug the charger in, the screen goes on. Same when you unplug. So that you see/know it's indeed charging. However, you can change the screen Sleep time and Daydream under Display.

if i leave my moga controller connected my screen keeps turning on

Happens to me as well, wild guess for me is there isnt a charging animation for the tablet when it is powered off, if i power mine off the second i plug it in to charge it will light up with a black screen 1st then proceed to normal boot, or sometimes there's a battery charging pic then it boots normally
