Hi All,
I recently took out my Tf701t after not using for a while because my normal laptop died. The tablet wouldn't charge and is now dead. When I plug it in, the charging LED on both the keyboard and tablet does no light up either. However, when pressing the power button, I do get the screen with depleted battery. I can also feel static electricity when I touch the laptop's metallic back.
Is it possible that the whole thing is dead? it's very strange that neither the keyboard or the tablet's charging LED come up, even if plugged in separately and it seems like too much of a coincidence that both batteries died at the same time.
Before I took it out recently, I had it out a few days before that when I was clearing stuff from my drawer and it did turn on then with some battery left.
Any help would be much appreciated.

Do you have the original charger?
The tf701 doesn't charge with 5v chargers it needs the 15v of the original one

Hi,
That worked! Silly me, I did not even know that there is any difference between chargers for mobile devices in terms of voltage.

hi, new member here.
bought my tilt on 10/4/07. has been flawless since that time.
used the nav quite a bit during a road trip, used a cig lighter usb charger.
got home and my battery was at roughly 40%.
put it on the charger at night went to sleep. in morning disconnected it at 8 am. shortly after i arrived at work i got the critical battery low chime. checked and it had like 7% battery life.
figured i didnt plug it in right, or it got knocked loose some how and didnt get charged.
put it in flight mode to minimize battery usage. left work at 2 30 pm (4% battery life) and put it on the car charger. got home and put it on the HTC supplied wall charger. light turned amber, so i assumed it was charging.
checked an hour later and turned phone on, it said 0%, and immediately died. left it on the charger for a few hours and the light was still amber, turned it back on and again 0% and phone immediately died and did a soft reset on its own. i turned the phone off and left it on the ac charger, took out the sim card and put it in an old blackberry to use while the battery was charging.
its been on the ac wall charger for the last several hours, i checked and the phone is totally dead, cannot turn it on, and the LED at the top is now RED.
what is the problem here? why wont this thing charge?
thanks in advance, i have alot of critical info on this device and any help would be greatly appreciated.
i cannot hard reset because i cannot turn the flippign thing on....
Does it charge when you connect it to your computer? If it does, then your charger is toast. If not, then it's probably the phone itself.
I'd try a different charger first. If that makes no difference then a different battery. If that still does not make any difference then time to exchange it.

connected to either the computer or the wall charger, the LED thats normally amber when charging, and green when charged, remains red.
I had something very similar happen to my wizard.
And as weird as it sounds, the only fix was to charge the battery in a friends wizard on his charger. I'd check the battery if possible.
Could be the battery. Know any place or anyone that will let you try a charged battery? If not, you might have to go in to an AT&T store.
i think i got it working. did some reading/browsing...
took a usb wire and cut the mini usb head off. dissected it and found the the red and black charging wires. took out the battery and held the leads to teh battery while the other end was plugged into a USB/AC adapter wall charger from a old blackberry. after manually charging the battery for several minutes, i put the battery back in the phone and the phone started up. now it seems to be charging off the wall charger and the led is now amber from red.
thanks for all your help/suggestions.
well it worked briefly. the amber light has gone back to red and it seems that the battery is not charging.
dont know what happened to my perfectly functioning phone.

Repeat this proceedure but this time do not turn the phone on, just plug it in to the wall charger once you have zapped the battery again.
Turning your phone on probably just caused the already recovering battery to die whiles it is trying to take on a charge.
It is mentioned quite a lot on the boards that Li-Ion Batteries do not like being over disscharged and there is usually a little protection circuit in the battery to provent complete disscharging although this circuit may be on board the phone. Completely disscharging a Li-Ion cell will kill it stone dead and it will need replacing.
When you took the battery out and so called jump started it with your flying leads, this possibly reset the little protection circuit in the battery so it can now take on a charge. I feel that once you turned on the phone, this was to much for the already depleted cell to take and possibly re-tripped its inbuilt circuit.
If you do manage to recover you cell, in future it is good practice not to let the battery go below about 25%. Li-ion cells are generally happy being top off regularly.
I hope this helps buddy
Do let us know!
Cheers

thanks, that was very helpful.
ive tried defibrillating this battery out of the dead several more times to no avail.
ill try it one more time when i get home from work, if its a no go i will go to teh att core store. the phone is 6 weeks old, dont know what they can do for me if the battery is toast...
That Sucks! I hope they'll give you a new battery.

I had exactly the same problem with my battery. It came on though after a day. Although the battery life after this happened went down to 10hrs max on standby. I sent the phone back and got a new one and now all is fine.
This is a problem that affects almost all makes of phone. There are three (main) causes of the problem:
1.
The battery charge drops too low to allow the charging circuit to recognise a battery is even in place (red no charge light stays lit)
possible solution:
http://forum.xda-developers.com/show...22&postcount=6
(in the end very similar in the end to the USB wire used in post above)
2.
A faulty battery (but if you can charge it using a cut usb cable or using a couple of AA batteries this may not be a faulty battery.
3.
A faulty charger OR a charger not delivering 5v at 1000mA as the OEM one does. Many chargers that are used for other phones or generic chargers only deliver 500mA. This is not enough when your battery drops very low. (these chargers are OK for occasional use but I do not advise using them regularly particularly if the no-charge syndrome has shown itself)
4.
A faulty USB connection on the phone. I have now seen a couple of reports where the fine wire connections in the phones USB port have become bent out of place.
Number 4 above is at least possible for the OP as it seems the battery will charge using a cut USB cable but not when either the PC USB cable or mains charger is connected. A USB port on the phone with a a bent internal contact would explain what's happening.
A previous poster was able with a needle or similar to bend the contact back into place.

i had the same problem with my phone.
put it in the charger overnight and woke up in the morning and couldnt turn on the phone with blinking red light. I don't know if my battery was over-drained though. I went to AT&T and was playing around with their charger and new battery and somehow the so-called dead battery started working again. They changed the SIM card on my phone there and then i haven't been able to use the phone since. I've changed the network to GSM instead of Auto setting under Phone Options which allows us to make calls; but now I can't connect to 3G network.
Charging thru mini usb
My phone started to exhibit similar problems...plugged in but no charging of the battery. I finally realized that my mini usb connection on the phone has been compromised (bent, distorted=not functioning properly) Now I have to prop the mini usb connection up at a slight angle to engage the charge. I think the plastic/metallic connector on the phone is somewhat fragile ...I had similar issues with my hermes.
called customer support.
they are sending me a new phone and battery.
how do i know its not a refurbished one? any clues?
before u send out your defect phone, have u check if your phone's mini-USB connector has bent or misaligned pins?
yeah all the connectors visually are fine.
My battery died last night and i charged the phone up and now the phone will not turn on anymore. Anyone have any ideas cause i'm completely out of them???
have you tried takin git out an putting in the phone again?
Yup. I dunno what is going on. I was using sony's cable to charge the thing and the power button was lit up red and now i switched to a different cable and the power button doesn't turn red anymore but the indicator lights are flashing like it doesn't have enough power to start. It may just be dead and sony's cable just stopped working and never charged the thing
Nope that isn't it... it just won't power on for some reason. i hope someone has an idea as to what is going on because i don't
I had a similar problem and had to leave it plugged in for at least 10 mins before the LEDs indicated it was charging.
THANK THE LORD THANK THE LORD. I was right. The crap cable sony uses just didn't charge the phone at all. Now that i switched i was able to turn the phone on again.
Try hard reseting the device while it is powered, might do something if its a software issue.
battery stone dead~won't recharge
I have the same problem. I don't believe ti has anything to do with the cable. The first time it suddenly came to life after a day or two fo being dead, but this time so far it is still in a coma. It did briefly awaken when connected to the pc, but it kept blacking out, and now it's completely gone again.
Could it be that it is not set to power off until the battery is completely stone dead, and therefore it won't recharge?
I think you are absolutely right. I don't believe it allows you to charge it until it is turned on. So try and plug it for like 15mins and try and power it on. Let us know if it works
This sounds like what I have seen on more than one device. If you let the battery go completely dead it will not take a charge from a USB cable to a PC or hub, even if it was a powered hub. We had some old HTCs that would only take a charge from a transformer when the battery had been fully depleted. It was like the USB to PC or hub did not give it enough amps or watts to turn it on and start charging.

Came accross this also in the Kaiser forums - think it has something to do with the battery being absolutely drained, so much that there isn't enough power to switch the current to the battery again.
Never happened to me, so never quite figured it out. But the Kaiser forum had a lot of discussion (and solutions I think) on this. (Xperia has HTC involvement..or so it's rumoured).

yep... I have had that happened to my blackjack 2 a couple times too. everytime I had to connect it to the charger for like 10 15mins before it can turn on again... plugging it to the pc/hub never work.... also happened once to my iphone as well
Hey I just ran into this problem today.
Turns out it was activesync messing with the phone
Ended the mobile device center process in task manager and phone went back to normal.
EDIT: Ok maybe its not back to normal. But it was definitely caused by activesync...
EDIT2: Back to normal now... Had to plug in the wall charger. After a minute the charging lights flashed and i was able to turn it on.
Checking battery status, and its in the red.. I guess the activesync was just a coincidence.
But wow, I left the thing plugged into my computer overnight to charge, and apparently it drained more than it charged?
There is defiantly something extra going on with the Xperia. While other devices I’ve seen fully drained refuse to start charging again from a USB to PC cable and even some power outlet charges. My Xperia is also doing as Nipperos. With an almost full charge I plugged it into the USB to PC cable and the icon went to the little plug and when I clicked on it the status said that it is was charging but when I got ready to leave for the day it had drained down one red bar. It was also very warm. With this, the $800 price tag and the random crashing made worse by the incredibly poor location of the reset button and made even worse by the incredibly poor design of the battery cover. Really, what is the proper way to get the thing off without breaking it? I’m fighting the urge to return it.
Any word on a new firmware?

I've noticed this too... My phone will be on full charge, i connect it to my PC to install a software, then i check one bar's gone... it drains more than it charges...
my x1 did this today. my buddy has a verizon htc phone and let me use hus htc wall charger and it did the trick...
my x1 is a x1i so i dont know if the US. plugs or what dont agree with the phone. but out of 6 cables and chargers only 2 will charge the phone from a dead battery the other 4 would only charge after it was on.
so my best solution for you all is to find yourself a htc wall charger and let it charger for 20 mins before trying to turn it on.
and of course theres htc involvment on the x1. look in the windows folder. all drivers are HTCxxx.dll the comm manager is htc. theres a forum here the htc developers site. this isnt a site for samsungs and other makers. this is a site for htc devices. if it wasnt a htc device it wouldnt be here.
My experience
I had a similar experience while on a trip to Korea. I didn't foresee that a 200mA difference in the current output of a wall socket charger will cause me so much pain.
I had always been able to charge the X1 with my Jabra headset's wall socket charger, hence I brought it on my trip. Not being mindful of the ratings, it can only supply 500mA, which is different from the X1's charger, 700mA. I was using it happily on a bus, happily keeping it alive with a solar USB charger (till it ran out of juice too). A while later, playing with the GPS I noticed my battery power dropped to 20% (2 bar) so I pressed the power button to conserve energy.
Unknowingly, the battery kept draining and the next time I wanted to turn it on I couldn't. The top 2 LEDs gave me 3 red blinks. I thought, "ok, so I just go back to the hotel to charge it with my Jabra charger."
When I tried that, I noticed that the power button gave a constant red LED and the battery did not charge. Taking out the battery and putting it back, I noticed the power LED went off (which indicates it was going to charge) but came back out again. It never charged.
Back home, after using the supplied SE charger, the power LED went off and never came back. I tried to turn on the X1 after 15mins and it powered up, showing the usual charging LED cycles.
Lesson Learnt. Always use original accessories.
Same problem here....
I knew about problem charging totally dead battery with wall plug-in (from previous HTC). Totally dead battery was not possible to charge via USB (from PC). But I have bought xperia via ebay and didn't know the wall charger is not original SE charger... Hope to work with previous HTC charger
Tx for coming to the idea
Just happened to me :S
I had used it all day and Wifi was turned on so obviously battery was almost dead. To save battery I turned off the Xperia.
When I tried to turn it on again it wouldnt and so I connected it to the pc.
That didnt work out so I connected it to the standard charger but that also didnt work. Right now my Xperia X1 is lying unplugged on the table because someone said you should leave it unplugged for a couple of minutes.
Hopefully it will work, I only have had it for 3 days :´(
Also hope this doesnt happen everytime your battery is drained because that would be annoying as hell.
--Edit--
Ok so what I did was I removed the battery and plugged it back in. This worked and I managed to turn it on and right now its charging.
Though when I try to go to sleep mode it turns the display on again after about 3 seconds and does what I am guessing is a low battery beep (Sorry windowsmobile noob here) but then stops instantly, which is pretty stange.
ok anyone know a way to increase the power wattage from your pc to the usb device? (sounds dangerous i know), but there must be someone who has had a similar prob and was able to fix with a bit of tweaking....ill google and come back with any results
okay...i had similar problem today morning..it wudnt start.
so i left it charging for ten minutes...and now it has turned on finally.
i think the battery goes completely dead.
i got zapped by the dreaded broken power button.
ive read up on a lot of soln from app/widget/rooting work around to solve the lock/unlocking. these work great.
but
my phone wont charge the battery any more.
this happened the same time the power button stopped.
the charge light is red not orange.
ive tried a plug in charger, car charger, usb, and my desk charger.
the desk charger saves my butt because i have two batteries and i can charge one while the other one is used by the phone.
so my question is:
is this simply a flex cable replacement fix?
ive read lots about the power button problem but i have not seen any accompanying issues with charging that im experiencing.
Sounds like two unrelated problems. If you fix/replace the power button you would probably only fix that and not the charging. You could check where the short is by backtracking from the plug with a multimeter.
Is the device visible with usb plugged in and doesn't charge? If that's the case you probably just have a short in one of the pins. But if not, that would need to be replaced.
hey EK,
thanks for response.
yes USB connectivity works great. and yes it wont charge while plugged in. When the battery lowers to a certain percent like 90% - i assume thats when the phone starts to charge it and when it begins this charge cycle, the battery light is red instead of orange.
ill give the multimeter a shot. i havent looked but wondering if there are any instructions out there for this check?
HH
The battery won't charge if it is plugged in between 90-100% as that can cause batteries to age quickly.

yup, knew that.
an update. both batteries do in fact charge. it just doesn't register as in charging mode for about 5 minutes - weird!
I can live with this. I'll just do a flex cable swap.

Ok basically I had my first battery drained completely (my phone was around 1 year ++).
I've been experiencing battery drains on my phone such that it is discharging faster than it chargers and I also realized that I'm unable to connect to the PC/ unable to mount SD card.
Knowing that my problem exists, I went on to a repair shop and they replaced my port for $S90 SGD. After replacing my port, I was happy that my phone can finally be connected to my PC without any problems..
Until one day, I realized my phone was discharging faster and soon it reaches 0% on my screen. I quickly plugged in the AC wall adapter and continuing using (by right it shouldn't go flat). To my surprise it went flat and I couldn't charge my battery at all, I was having the Orange LED light.
So I went to the repair shop again and they sort of bumped my battery up and charged my phone. Seeing that my battery discharges faster than it charges, they told me they my battery is damaged and so I went on to get a new battery...
New battery came, I plugged in, turned my phone on successfully without any problems. Battery was at 65%. I left it few hours to charge and WTF my battery turns to 19% and eventually flatten out again .
Now here's the thing.
My 1st battery, (Totally unable to charge, No blinking orange LED)
My 2nd battery, when I leave it for a few hours (I plugged it in and there's orange LED), and soon there's not even an orange LED light anymore.
I really do not know what the hell is wrong with my phone. I'm so disappointed. I just thought that it might not be my battery's problem because a brand new battery shouldn't have any problems..
Really need some advice noww :crying:
Gonna cry. Wth is wrong with my phone?!

You might have apps that are drawing too much current, a charger that's not supplying enough or is not recognized as ac charging.
Install current widget or something similar to see both how fast your battery is draining and how much current the charger is supplying.

My old Inc S did the same thing as what your describing, and the charger port was faulty. I had to wiggle the cord into the perfect position to get it to charge, and even then it only actually charged half the time. Got it replaced by bell.
When you plug your charger cord in, does it wiggle a lot to the left or right? As in more that it normally should?

The problem is I can't even turn on my phone at all to install any apps because my battery is completely drained. I just don't get it how come my phone drains the battery faster than it charges. Perhaps it's my charger not supplying enough power .
It's my second battery already and I'm now sure that it is not a battery problem.
Should I change an adapter (like maybe the iPhone adapter head) and use my usb cable to charge my phone. Will it provide more current

Well, I am not sure whether if it was charging port that was fault. It indeed charged when I tried my 2nd battery when it first came it had 65%. I went on to charge it and the percentage drops when it was charging (when the phone is off) . Perhaps it's not the apps that are draining all the current.
My phone is losing current... My 2nd battery is also completely drained off after sometime and I'm unable to on my phone. Irritating max.
My charging port just got replaced because I cannot mount my SD to the computer and I had it replaced and I was able to connect to the computer and LED indicates it charges.
What could be the other reasons that my phone is losing current? I'm not sure about hardware parts, but maybe perhaps it's the charging gland or whatever things inside the phone that is damaged?
Leave charger plugged in while light flashing. If the light goes off unplug and plug again. You might need to do a few times but the orange light should stay on eventually. Let it charge a while before switching back on. Good luck.
HI all,
C6903 would previously charge using an official Sony dock cord. Yesterday, however, the phone started making the 'phone flat' beepjng noise (it was close to flat), so plugged into the dock to charge. The beeping continued every few seconds, the screen rotation started playing up (I do have a screen rotation lock that hasn't been a problem) and the phone won't fully charge (the charge symbol is there, just keeps dropping. The error message "the connected power source is not sufficient. The battery is draining faster than it is charging. Minimise device usage while charging" popped up. It does charge VERY slowly if the phone is off airplane mode and the screen is off (it charged approx 30% in 10 hours, this way).
No rogue apps, etc. I reset to factory settings and the problem is still there. Phone charges fine using standard micro-usb.
Here in the NL, the carrier (KPN) send your phone away for minimum 2 weeks (& will not give you a replacement), and they will likely just test with the standard USB charger, which is fine.
Anyone experienced this & any advice would be greatly appreciated. Thanks, Adam
sounds like the cable is faulty, probably only one way to find out if you know someone with a dock - or just send the dock back to were you purchased it declaring it faulty
I've had similar issues, I solved it by rebooting the phone and plugging it in using sony usb charger until the charge is over 30%, after I got mine to 30% using usb, it then was able to charge using the dock.
you could check the dock with a multimeter, but there's not really much to the dock itself, so unless it's a broken wire, the problem is with the wall charger which the docks plugged into or the phone
Thanks all. I will check if it is the dock/cable or the power plug when my wife gets home - she also has the Z1.
Thanks again, will keep updated.
Adam
Yeah, sadly the cables don't last too long - went through 2 cables up until now and many more to come.
