TF701T won't charge - Asus Transformer TF701

Initially, it wouldn't switch on at all but, after a while it showed the battery empty gauge and wouldn't turn on, even though the power cord was attached - and, in any case, it should have been fairly well charged.
After a while I opened it up again and it had a dialog in the centre of the screen saying 'Android is upgrading... Please unplug the power adapter before updating the Pad firmware'. I did; it turned off.
Subsequently, though, it turned on with the power and dock connected and everything was working as normal. The dock was charging, but the tablet wasn't.
I've done a factory reset from the Settings menu to see if there was something about the interrupted firmware update that had stopped it charging and it still worked afterwards, but still wouldn't charge. I did an erase/reload from the Bootloader menu and that didn't help either, but then prompted me for a system update. This insisted I had the power cord in (which seemed to make more sense...) but after the first reboot it didn't restart. I gave up at that point and, when I went back it was saying 'Android is upgrading... Please unplug the power adapter before updating the Pad firmware' again.

Yeah, those Charger plugged and not plugged messsages are totally misleading. First it says disconnect the charger (otherwhise update would not continue) and when the update is actually underway it says "do not disconnect the charger during the update".
Yeah, right, Asus. Totally makes sense.

And, of course, if you don't unplug the power when it tells you to, it doesn't proceed. And if you do, there's no charge, so it switches off. And you're back to square one... If the firmware change fixes the charging problem, I'll never know because it won't install.

This is probably a bit late to help, but for what it is worth, I have had a similar problem with my almost new ASUS TF701T; it simply would not charge. Dock battery State of Charge (SoC) fell to 0% (although all keyboard functions operated normally, I suspect powered by the Tab battery), and the Tab SoC steadily fell from a high % slowly towards discharged.
Nothing I could do would get the thing to charge, either the Tab or the Dock.
A bad charger or a bad cable was the next thing to suspect. I did try to charge from different power points - always the same. No charge (although, to be fair, the "Power Saver" icon did show that charging was occuring, but still the SoC fell. There were no charging lights on either the dock or the tab).
I considered Factory Resets as suggested by various forums, but fortunately, I didn't. I eventually ordered a new USB charger cable. And still no charge.
It was then, by accident, that I tried yet another power outlet for charging - heh Presto! Full charging almost immediately.
What had changed? It was then I noticed that on all previous charging attempts where I experienced this difficulty, I was plugging the charger into either power points, or power boards which had "surge protection". And by chance, this last time, I had plugged the charger into a "non-protected" power outlet.
I have since replicated the problem, and as such I have concluded that the ASUS charge adaptor does not like power which is subject to "surge protection" as so many power points are these days.
In my case, the power network is 240VAC 50Hz, but I suspect that "surge protection" can be implemented on any grid power system.
I hope this helps someone.

Urgent help about the battery

I posted this question before, but no one answered. But this problem drives me crazy!
My Kaiser turned off when the battery was running out.
When I connect wall power to charge it, the orange LED indicates it was charging, but just few seconds later it automatically boot, and the orange LED was off.
The problem is, it can't boot into OS due to low battery(it only shows "Smart Mobility", but can't even enter bootloader mode) And only if it boots into OS successfully, it can be charged.
Anyone met this problem on any other devices before?
How can I stop auto boot when charging?
What can I do?
That must be something specific to the rom on yours... mine does not automatically boot when when power is applied (assuming it is off, not just in sleep mode), and it charges fine when powered off.

Thanks
I use the ROM from this forum
RUU_Kaiser_HTC_WWE_1.56.405.5_radio_sign_22.45.88.07_1.27.12.11_Ship
What is yours?
I'm just using the stock AT&T Tilt rom.
Here's the fix!
Yes, I've had the same problem a few times on my Vario (Wizard). Very annoying.
Here's what to do:
- Take a mini-usb cable (the one you use for sync and charging from a PC) and cut off the mini-USB connector
- Strip the wires
- Take the battery out of your TyTN
- Carefully connect the ground wire (black) with the ground connector (-) on the battery. Fix it with clear tape.
- Now do the same with the (+) (red wire).
- Attach the USB cable to a running PC and let the battery charge for about an hour. After that, put it back in your phone, you'll be able to boot it up and charge it the regular way.
Yes, it costs you a cable, but it solves the problem.

I think you misunderstood. The problem is that the phone only charges when the OS has loaded completely. So if you really run your battery out completely and there is not enough power in your battery to boot up the phone (read: it turns off again before the boot has completed) you won't be able to charge it the regular way. SOMETIMES a heavier charger (2A) does seem to be able to charge the battery even with the OS shut down, but most of the times it won't work anymore... see below for fix.

Based on this, it sounds like it is starting to charge without the phone booted (orange LED on), but for some reason it then automatically boots up, then crashes because there's not enough power(??)
But if the problem IS that the phone only charges when the OS has loaded, that is also not how my phone operates. In fact, that even goes against the manual, which tells you to plug the phone in (without turning on the phone) and let it charge fully for the initial charge before turning on the phone and allowing it to boot.
Sorry if I misunderstand, but neither way is how my phone operates... it can charge without the OS loaded, and the phone does not automatically boot once power is applied.
Not sure I fully understand what's going on here but, I am wondering if the power on/off button is stuck in (i.e the micro-switch is clicked in and not releasing). I cannot think of any other reason the device would turn on when connecting the charger if the device is powered completely off. ( Except perhaps shorted connections in the Usb port)
Mike
To SteRo:
Thx a lot for the solution, I tried, but still doesn't work.(I charge it more than 2 hours, and still can't boot into OS)
To mikechannon:
yes, it happened. :-( the power on/off button is NOT stucked. And the device is powered off completely.
To All:
Thx for your reply. What I mean is almost what dscline said:
It starts to charge without the phone booted (orange LED on), but for some reason it then automatically boots up(around 15 sec after I plugin power), meanwhile orange LED is off. But it can't load into OS, just re-boot again and again because there's no enough battery. That makes it's impossible to charge, 'coz it's only charged when the OS has loaded completely.
Anyway, I called customer service to ask them replace the battery. I may try to use different ROM and see what will happen. I'll post the result here.
It's also possible that it has nothing to do with the battery or charging at all. I just checked mine, and the charging indicator is lit with the unit off, but it does go out for a bit during the boot processes, then comes back on again. So what you're seeing with the charging light is normal. It may simply be that there's something corrupted, or some other failure with the device, that is causing it to not boot properly, and get stuck in a reboot loop. If so, it will probably do the same thing with a completely charged battery. You may have just been assuming that it was related to a low charge.
That's what I'm worry about,, Coz I can't boot it by SteRo's solution.
okay... they say trouble comes in three's...
Yesterday I flew to Asia, 20-hours with a full charge. No suprises during the trip. Checked email from Narita during the layover, no prob. But after I arrived in Taipei I received the low battery warning. Plugged in my usb-to-usb (notebook to kaiser) cable and "no charge light"!
This morning I plugged it into a ac battery charger and waited for >10 minutes, still no charge light.
Now, at the risk of a battery, I'm attempting to charge the battery removed from the kaiser using the previous mentioned method. In an hour I'll test it.
This afternoon I'll pick up a new battery charger and spare battery.
In 14-months with my trusty TyTN (cht9000) I never once had a problem like this... I'm a little bummed right now...
[update]
okay -- battery is okay and can be charged externally (using the two wire method or an external battery charger). BUT... the device still won't take a charge using either a direct AC adapter or a USB cord. This was also retested after performing a hard-reset. Not a good sign folks.
The charger works (connected to a Trinity), so it's not the problem. They battery works (charged to 45% after 45-minutes connected to an external battery charger). The HTC OS after a clean hard-reset used to work but now doesn't, so it's unlikely it's software related.
I've made no other modifications to the bootloader or SSPL... everything is original stock. Wish I had my TyTN with me right about now...
Sounds like something I had on my previous TyTN:
The power connector was a bit flaky on my charger at home. So when I'd hookup the powerlead it would charge to 10 secs or so and then no longer charge. I had to put some pressure on the connector to have it continue to charge. So I put a ballpen on the powerlead, just under the phone, when charging.
It's a long shot - hope of use. When you've connected the phone to power, and the orange light goes off, try wiggeling the connector a bit - see if that helps.
Hope of use.
Re
OK,
I've got excactly the same problems... I dont want to make you illusions, but you cant solve it and you need to send it back for repair. Your usb connecter on your tytn is broken...
first i will tell my story...
My tytn did excactly the same, shows the led, powers on automatically (normally it don't do that, so it;s not a rom issue) and then powered down in the smart mobility screen. I tried 4 chargers, and 2 battery's. with a full battery it will power on and load windows, but unable to charge. with the empty battery it will power down in the smart mobility screen. soft reset, hard reset, it won't work.
You can check if it's the same problem, by attaching it to your usb on your computer and call up the bootscreen by pressing the camera button and stick your stylus in the soft reset hole. If it comes up with serial instead of usb, then your device usb connector is broken.
BUT, you can charge your battery in a very strange way i figured out. since i am on a buisness trip i need my phone and don't send it back!!!!!
ok, this is what you have to do, plug in the powercable, call the hard reset screen BUT DON'T APPLY!!!! you will notice it will not power down, so just leave it on this screen for a night with the cable connected. you don't see the charging light, but actually it is charging. for me this temporarely solution works fine... but when i'm back in about seven weeks i send it in for repair.
Hope this will help you!
Swiftgs:
Many thanks for your insight -- you are correct, in bootloader mode the Serial shows instead of USB. I just purchased a spare battery (1100mAh, made in Taiwan) and battery charger for US$17. It'll get me through my business trip, but this is disappointing. As I mentioned in my earlier post, I used a TyTN for 14-months (July 2006 to Sept 2007) as my primary phone, recharging it daily via the USB connector and on a desk charger in my office. I can only conclude that if the USB is physically damaged (not evident visually), then it is not as robust as the USB port used in the original TyTN. The strangest part of all is it worked perfectly until the battery level fell below 10%...
FWIW: I purchased the phone through R&D Marketing. Ron Webber quickly responded to my note and gave me a contact at HTC America. I'll follow-up
after I return and report my experience.
Cheers
well, thanks for all of your replies/infomation.
I tried evey possible methods mentioned above, unfortunatelly none of them works :-(
and the most depressed thing is I filnally get a new battery, but it still doesn't work!
So I sent it back to repair, cross figure...
It works
I would like to thanx 2 SteRo for his advice. I am using Qtek 9000 and had the same problem. Battery was empty, and I tried many times to turn on my PPC, but without success. All the time when red light appeared after 10-15 sec display become black and tried to restart from boot again, and it's happened many times. Finally I thought that I just can trow my Qtek, but seeing your recommendation decided to try. I took USB cable cut it and strap the wires. Connecting red on (+) and black on (-) after 1 hour charging I was able to start my PPC, to recharge battery by 100% and it is working now OK. I must check duration of the battery tomorrow, because reason why I discharged battery was automatic turn off of my PPC when it was on around 45-50% battery capacity. Tomorrow I will check how it's working when I recharge battery again.
Dear SteRo you are the king.

[Q] Battery discharging when on powered USB

Here's an interesting discovery - would be interested to know if anyone else has the same issue.
Basically, my old WM6.5 phone (Touch Pro) used to take charge from a powered USB socket, even when the computer was turned off.
Plugging the HD7 into the same USB socket, and the phone won't charge. That's fine, I can understand there may be valid reasons for it.
What's *really* interesting is that if I leave the phone plugged into this powered down PC overnight, the battery is pretty much dead in the morning. Compare this to leaving the phone unplugged completely, and I'd generally see 15% battery usage overnight.
The solution is pretty simple - don't leave the phone plugged into this USB socket, but it seems odd.
Any chance someone else can try this?
Is the Zune client on your pc open because my phone will not charge with zune open
but once i exit out of zune on the pc it charges fine...
ive lost my charger and too lazy and cheap to buy a new one so im just using the pc to do it....
no - the PC is actually powered down. However, with soft power switches, the USB port stilll can get power, as proven by my ability to charge my Touch Pro from USB when the PC's off.
I'm not sure what could be causing this, but i will try to see if mine is the same too, then i will post feedback
I've charged mine on a USB port at work, but there isn't any Zune software in the way there... Honestly, I don't sync through USB, so I never noticed this, but at work I have used the USB port on our camera system to charge my phone...
most likely cause is the fact that the computer reduces the amount of current send to the usb port when powered down.
normaly all that is needed is a move of the mouse or a key press to power the computer back on.
now both the keyboard and mouse are low power devices.
now my guess is that the touch pro needs less power in standby then the hd7, and therefore the first will charge and the second will drain.
so to solve this question you need to measure the power comming from the computer in standby (powered on it's 500mA), and both the phones in standby mode.

Here's what I find odd:
The phone will not charge unless powered on. For example, if I have the phone turned off, and plug it into the wall charger it came with, the phone boots up. It will NOT charge while turned off.
Anyone else notice this?

i saw someone mention that the led won't turn on during charging while the phone is turned off.
sadly he didn't wait long enough to see if the led turns on when the battery is fully charged.
also i have no idea which model he was using.

I posted earlier about charging issues on the HD7: http://forum.xda-developers.com/showthread.php?t=849548
What I found was that if you have the HD7 plugged into the USB port and then you suspend/shut down the PC, it'll stop charging (while all other phones I've used - iPhones, HD2, etc. - will keep charging).
Once you suspend/shut down, you need to then unplug and replug the HD7, and it should start charging again. Not sure why this happens, but I need to do it every night, otherwise I have a dead phone in the morning.

[BUG] N4 charging stuck at 99% and other charging related issues

is it just my unit or anyone else have this issue? the battery indicator (lock screen and notification bar) shows 99% and just wont go up anymore.
UPDATE 2: Trick - when the phone stop at 99% while charging after a while, unplug the cable and immediately plug the cable back in. The battery indicator now should show "Charged".
UPDATE 1: Seem to be a safety mechanism to protect the battery from overcharged.
Also notice the following issues:
2) battery indicator may show as still charging when cable is already unplugged (only happened 2 times so far)
3) screen on by itself randomly while charging (not always but do happen some times)
4) battery discharging mechanism (to protect from over charge) may go haywire! It may go down from full/ 99% to 90% or less while still charging (may be related to (1) ).
Check your cable while charging. Also check to see if its charging as AC not USB. When it switches to USB, then screen will turn on.

Can't speak for the other 2 issues, but only charging to 99% isn't really a bug. This used to occur on the Galaxy Nexus. More reading here
Battery Charges Only to 99%
You can just ignore it, as it's apparently a way to safeguard the battery. Not sure the exact percentage point at which your battery stats reset, but it will have already occurred at 99%, for sure.

I was charging with AC, and I used a cable which is for charging only (can't transfer data). I tried it again today with the original cable from the Nexus 4 box, and have not noticed the screen turn on by itself again... Suppose it is the cable fault.
As for the stuck charging icon, it happened twice since I got the phone, but have not appeared again. Can't pinpoint the issue.

Ah... this is my first Nexus device. Surprised to find that it is actually a safeguard feature :silly: well as long as it is not faulty I guess I just have to get used to it. Thanks for sharing.
It has to be the dumb usb adaptor that comes with the phone. Mines charges perfectly fine to 100% using an LG AC wall charger I bought.. And even if I restart the phone it stays as charged at 100, USB would be at 99% when I rebooted..

[Q] Touchpad won't boot

I cannot get my sisters TP to boot. I guess she let it die completely, so now when I plug it in, all I get is the home button to blink back and forth. If I try to turn it on, I get the red battery with a lighting bolt icon, then a white plug icon, and when I plug it in from there I get the "To reliably charge" message. I don't have the original ac adapter or cable because she lost it. I have already reflashed the A6 firmware. Also, if I leave it plugged it with the home button flashing, after about 20 minutes or so, the flashing stops for a few seconds, then starts for a few seconds, then stops again and so on and so forth. Is there anything else I should try? Or is this thing dead?
See if you can get an OEM cable or a Touchstone.

You need to find an original charger or maybe a compare able 2amp Carter will work. A standard phone charger or USB port on your computer is not powerful enough to charge it.
Check amazon it shouldn't cost more than $10
I have another tablet charging block that is 5.0v and 2 amps, but when I use that all it does is make the home button flash then stop then flash again. I left it charge on my computer overnight to try and get it to trickle charge. When I woke up the home button wasn't flashing and when I try to turn it on, the red battery comes up for a second then the white plug icon. I guess I'll see about getting an OEM cable, hopefully that works.
UPDATE: I got it into "recovery" mode? It was plugged into my PC so I held power and vol up until my pc recognized it. But it's showing up as palm in the device manager, and no drivers seem to work for it.
UPDATE 2: My sister found her OEM charger and now it seems to be actually charging. Thanks for the help, I'll let you know if this doesn't work.
Yep, usually issues like that are because of not using the OEM Charger.

Battery dead, bricking issue
I have had several charging issues with my Touchpad. I am using ClassicNerd Butta OS. IF I am using the Android OS (Butta) and I turn off the Touchpad and then plug it in to charge it will restart the Butta OS. When this happens the Touchpad discharges instead of charging. So, when I come back later the Touchpad is dead and it takes a lot of messing around to get it going again. To prevent this I always turn off the Touchpad when I am using the Butta OS but I don't immediately attach the charging cable. Instead, I wait a bit. Then when I plug in the charging cable I immediately switch to the WebOS operating system. The device seems to charge well using WebOS. When it is done charging I unplug the cable and turn the device off. Next time I restart the Touchpad I let it boot to Butta. Then when it discharges to 80% or so I start the process again as stated. Sticking with these procedures has prevented the no-charge / no-boot issue from reoccurring. I also no longer charge the Touchpad at night. Instead, I charge it in the morning or during the day and only leave it on the charger for an hour or two until it is fully charged. It is my understanding that technique should result in longer battery life and better (longer) charge in the battery.
When my Touchpad battery has gone completely dead it is a real pain to get it to charge up the battery again. When the batter is totally dead the device will not boot into any OS or allow me to even get to the boot loader program. Takes a lot of messing around to get it to start charging again. Though I have been able to, eventually, get it to boot into WebOS and start to charge. But this was not an easy process by any means.
Also, I would agree that you really need to get a stock charger with the cable for your Touchpad. Using a different charger could damage the battery in your Touchpad and/or cause the battery to charge too slowly.
Good luck!

My Hp TouchPad tablet came today and I was told when bidding that it was doing exactly the same thing as mentioned here. I have the OEM charger and cable.. I'll let you know when I can get it straightened out and I hope it is a good one.. Thanks for the info..
While on the OEM charger it booted and I selected webos for the tptb to reflash A6, but soon after it was off charger it went back to the battery icon. battery life low I guess? I selected shutdown. Let it charge over night and see what happens.
Many thanks to many members who are so helpful...

[Q] HTC One Will Not Charge

My HTC One had a full discharge a couple days ago.When I got home to plug it in, it showed a blinking red LED and the battery charging animation, but didn't charge at all over a full day. I tried rebooting while still plugged in to the wall charger, which took me to the OS. From the OS I could do anything -- text,call, use Chrome, etc -- but the battery symbol had an exclamation point and the LED was still blinking red. As soon as I took it off the charger, it turned off.
I have tried Power + Volume Down, Power + Volume Up + Volume Down, and the bright light methods.
I was able to restore the phone to a previous backup from TWRP while plugged in, but the problem continues.
Any suggestions?

Try connecting the phone to your computer's USB port. If it charges there, then your charger is bad. You can check to see if is charging by going to Settings -> Power on the phone. If you are using the cable from your charger to connect to the computer and it isn't charging then try another cable. It that works, it may just be the cable that is bad and the rest of the charger is OK.

I have tried multiple cables, including the HTC stock cable and charger. When I plugged the phone into my computer, it did not show the blinking red LED and did not power up. The phone was basically unresponsive. I assume this is from lower amperage from the laptop's USB ports, but could be wrong. The laptop was also plugged into its charger at the time.

The battery is severely discharged. Since, it will not charge via the charger or the computer it looks to be a phone hardware issue. You probably need to take it back to your dealer for servicing. Before you do that, give the connection to the laptop one more go except leave it on the for about an hour or two undisturbed. When batteries are severely discharged, it takes a while for it to recharge enough to give any indication of life.
I ended up sending the phone to HTC. I had modified the kernel and OS, but figured it was worth a shot since the phone was dead and it was still under warranty.
They told me it was out of warranty due to liquid damage. I have no idea how it may have been liquid damaged, but oh well. I wasn't going to pay the $200 to replace the motherboard so I asked them to send the phone back to me.
I received the phone last week and plugged it in. I wanted to make sure I could repeat the symptoms and that HTC hadn't further messed up the phone before I took it to a local repair shop. But what happened when I plugged it in? It came to life and began charging as normal. Either a generous HTC tech fixed my phone for free or the phone needed some interior jostling to get circuits back to normal.
Whatever the situation, my phone has been good as new with all the data just as I left it. For a full week, I've had no problems charging.
