Sometimes I let my battery run to empty. Everytime that happens I can still hit the power button and my K-Jam will do a soft reset and then turn off shortly afterwards. I let my phone die yesterday when I was on the road. It won't turn on and it doesn't appear to be charging. I checked the battery with a multi-meter and its showing 2.5V on a 3.7V battery. Is this too low for the phone to work? Can anyone think of a reason why it would be completely non-responsive? I bought the K-JAM on ebay and its not really sold in the U.S. Does anyone know somewhere I can bring in my K-Jam to get parts or at least some advice. Thanks for your help.

Lithium batteries behave differently from NiCads regarding charge discharge cycles.
Where NiCads *like* to be fully discharged before recharging, Lithium batteries *hate* it. They prefer to be topped up regular and often.
My guess is that you have a dead battery given the way that it has been abused (by being treated like a NiCad)
Really, I thought Li-ion was a deep cycle battery? Well should the phone show any signs of life if it is plugged in and has a dead battery? Is their a way to test the hardware without replacing the battery. If replacing the battery is neccessary. Do you know where I can find one? Thank you very much for all of your help.

I had the same problem some weeks ago. If the battery go down to much and wizard switch off then you have big problems because this ppc charge only when OS is loaded!
So if you are not able to switch on to charge it you have to charge the battery outside the phone.
This problem happen to me when i was traveling and i forget my charger at home... I bought another USB cable i cut it to take out the red and black wires, then i take out the battery from the wizard and put red wire on the pin with label (+) and black wire to the pin (-), the pin label are written on the battery. I put attention to don't make shortcuts and that wires and pin was touching and let 15 minutes to charge (natually the USB was attached to my laptop). Then disconnected USB cable from laptop, put the battery on wizard and switched on it pressing the power button few seconds. It booted up and when OS was loaded i connected the normal USB cable to the phone to finish to charge it.
Now i charge the battery before that reach 0%!
Thank you so much, I will try that as soon as I get home tonight. If I understand you correctly it sounds like battery charging is software based and not hardware based, which is a major design flaw. If this is the case I'm going to sell my k-jam, because that is bs. Do you know if Jasjar is designed the same way? Thanks for all of your help.

This works !!!!!!!!!!!!
I had the same problem. I thought my battery or my device was defect, but following this instructions I was able to charge my battery again !
THANKS A LOT
had the same problem some weeks ago.
battery was down so low, that after plugging in the wall charger my pda booted, just to switch off again after a few seconds.
so what i did was going into "serial boot mode" - that way imho the pad doesn't turn on wifi, bluetooth, sd card and things like that that drain battery too much. after some time the battery was loaded and i could reset the device and go on working with it.

You are a lifewsaver -- I woke up this morning to a dead battery and a device that wouldn't turn on and using your tip was able to revive it in a few minutes. I really can't imagine how someone could have designed a device that can't recharge a dead battery. Very dumb.

Thanks Dalamario, it worked for me.
A small amount of electrolyte goes a long way
I just found this thread as my O2 Wizard did the same two days ago.
Once I realised which was positive and negative I just applied a fine lick of saliva onto the positive and negative terminals of the battery and the phone's battery terminals.....
Lo and behold, it worked !!!!
Shame I logged a call with O2 earlier today and they are sending out a replacement!!!
Frustratingly I put a friends battery in mine, transferred everything off and emptied the phone's memory!!!! grrrrr, I should have thought about it first.
To add to that...the standard battery is some cheap and nasty Chinese battery.
Sadly, all the aftermarket ones are mostly made in China too!
BTW. Drinking an acidic fizzy drink probably helped the revival process by making my saliva that little more acidic.
Unbelievable.
I had the same problem last night. The phone just went dead while I was working. I could not get the thing to take a charge overnight with a wall USB charger.
I took a cheap USB printer cable. Cut off one side. Isolated the black and red wires. Attached them to the +(red) and -(blk) on the battery for only two minutes. Put the battery back in the phone and turned it on. When it booted up I quickly put it on the USB charger again. And now it is charging as usual.
I guess someone may need to start marketing a USB with blk/red pigtails for emergency charging.
Thank you soooo much!
Dropped my MDA Vario in my pint of beer the other night - had 48 hours of worry as it dried out and things began to work again. Then had the problems described before - not able to charge, red warning LED. Didn't want to put it in for servicing as it is unlocked (and smells of beer!) but found this solution which works perfectly (I used blu-tack to attach the terminals)!
Excellent!
So.. here goes my problem..
Got my Qtek 8310 three days ago, and the very same day I got it, decided to upgrade from WM5 to WM6. However, the battery charge meter gave me wrong info about the battery charge percentage, and the phone battery died just after I formatted the BINFS and re-setted the device in TeraTerm.
The device still powered on, after each USB cable re-insert, but died, after 5-10 seconds. After a couple of attempts, the phone didn't turn on at all.
Did some info search on the web and found out, that my battery fell to an critical voltage level. Li-Ion batteries require a certain voltage to even be able to accept a charge.
As I got an non-original battery (Sanyo ST26C) I suppose it is poorly designed and doesn't have good under-voltage protection (I have read about other HTC models (e.g. Wizard) having this problem as well), so the battery dropped below these limits and phone now identifies the battery faulty and doesn't let it charge. This is for consumer safety, because attempting to charge damaged Li-Ion cells can be dangerous, as Lithium is known to be able to catch fire/explode.
So the phone doesn't let to charge the battery in any way (1amp wall charger or USB cable).
Anyways, I tried to jump start the battery (charge with bare wires) to give it initial charge and... it worked. However, there goes my main problem: As soon as I insert the battery which has the initial charge, the phone starts immediately and boots to a bootloader (as there is no OS, formatted BINFS) and the the phone does not charge while in bootloader.
Then, I tried to turn off the phone: Hold down power off button for 5 seconds - phone turned off. But as soon, as I release the button, red light flashes once (as it does everytime, when you try to turn on the phone, it's normal) and then orange LED comes for a second, indicating a charge (as the battery is no longer considered faulty - phone lets it to charge), BUT then phone starts again to the bootloader and it somehow prevents further charge.
So: as soon as I release the power off button, after the phone has shutdown, it starts again, everytime, and soon the battery dies again.
My own thoughts of solving this:
* Get a fully charged battery from a friend, install the windows on the phone, and then charge my own battery (I know noone, who may have HTC Tornado, will be hard to get);
* Buy some standalone dock charger, which can charge batteries directly and charge the battery happily (haven't seen any around yet, so will be really pain in the arse, to get one);
* Charge battery with bare wires for an extended period of time, to give it enough juice to install windows (which I strongly doubt, as battery damage could occur);
Any other ideas? Ideas and comments, from people who know, or had similar experience is more than welcome. Looking forward for answers
Its funny. Reading you I've realized what people tell me about "I make a question and I answer it myself" So... You have the answers my friend. For options 1 and 2, use E-Bay. As a matter of fact, there is an aftermarket charger in ebay that charges your phone and a spare battery and it includes the spare battery when you buy the charger. I believe it runs for under $20.00. For option 3 use some wood cloth pins(those used to hang cloth to dry). I would say with at least 2hrs charge you should get a good 50% charge on your battery, enough to flash your phone.
Edit: Here is an Ebay Search. But, keep searching till you find the one that includes the extra battery. Chances are your battery is no good or won't last you very long.
Good Luck!
Get a new battery man, these li ion batteries, are no joke, especially the fact that they are made in China/Taiwan, I myself had used a tornado battery even till the days when the battery has bloated and cracked the back cover, when a single charge could not even last 4 hours.
Those days, were like having a timebomb in your pocket, ended up I got mysel a new tornado at a price cheaper than a replacement battery.

Thanks for the suggestion. The main reason why I am in serious doubt about this option, is that standard chargers usually have some sort of regulators and monitors the charge, prevents from overcharging, etc. But on the other side, USB charge output is only 100 mA, so it couldn't be that bad if you think about it

Well, the fact, that it is manufactured in China actually says nothing Many companies choose China to manufacture their products because of low costs. And the most of electronics is manufactured in China and other Asian countries.
Anyway, before getting myself an new battery, I would like to try resurrect this one If this won't last long for me - no problem, I will get an new one. But until I'm convinced enough, it's a waste of money, which I don't like doing
And one more thing.. maybe someone knows a way to keep the phone power off?
Because as I said earlier on, it's charging only when it's turned off, and not in the bootloader. And problem is that, as soon as I put the battery, it starts-up the bootloader.
Get a desktop charger perhaps?
Or if you are adventurous enough, mod the USB cable, and charge the battery directly, only if you know what you're doing, and only if it works

Well.. thanks for the answer, but we've already discussed this option and now I am asking whether or not, someone knows a way to turn off the phone and keep it turned off (prevent from self startup) while the phone has no OS (got formatted BINFS).

I've already done that, and yes, it works. But I need someone to confirm, if it is safe enough to charge the battery for an hour or two.
Have anyone tried that?
I don't think that it's very safe. But I was having a similar problem, and I just left the phone connected to the power cable, and even though it seemed like it was not charging, it apparantly was.
Or you could just get a new battery. On expansys I saw a new one for ~$20.

Well..
With a modified USB cable (bare wires), which got power output of 100mA I have charged battery directly for approximately 3 minutes, and the phone turned on, and was operational for 4-5 minutes until the battery died again.
And before that, I've tried leaving it on an mains charger, which got power output of 1A (1000mA, 10 times USB). I left it for a hour or two, although no led was showing up to indicate a charge. The phone didn't event turn on after this 2 hour "charge".
And the reason for this is explained in my first post. Will try to leave it charge over a night, though, expecting for a miracle

But new batteries usually come empty, so it's no use to me. I have also explained why, on my previous posts.
So before buying an cradle charger, I would like to find out if these budget-friendly solutions will work:
1) Find out how to keep the phone powered down (because it's the only moment, when it truly charges);
2) Find out if it is safe enough to charge battery with bare wires for extended period of time (1-2 hours);
Just came up with another idea. Searched the forums and found a very similar problem to mine:
fritzgerald said:
For some odd reason my wizard likes to say the battery is full when its actually dead and that it's dead when it's really full. Well a few days ago I was reflashing to try and take care of the issue and it died during the middle of flashing. It would only goto the bootloader screen and would not charge. Well I decided I'd post a few pictures of my recovery technique utilizing my wife's phone. Cat5 cable striped at the end and twisted to each of the positive and negative battery terminals and the Blackberry's battery put it so I could use it to power the wizard.

So.. I've got a Sony Ericsson w810i, would this technique work? The w810's battery is Li-Polymer, 900mAh 3.6V (although some sources say, that this exact battery is 3.7V..), compared to Li-Ion 1150mAh 3.7V Tornado's battery.
Voltage seems suitable..
Haven't got any answers to my previous posts, so I tried.
The trick worked, Sony ericsson's battery can feed HTC Tornado perfectly. However... got another problem..
Here's how I wired it up. The positive wire takes two contacts and the negative takes another two aswell. The ends of the wires are then connected to the sony ericsson's battery. Phone starts, and boots to a bootloader. Everything's seem to be perfect.
Then I plug in the USB cable into the computer, the other end to the phone. Phone recognizes the cable and puts label "USB" at the bottom of the screen.
However, there's something wrong with the connection.. TeraTerm fails to connect and Update ROM utility fails, too, with an "cannot connect" error..
After that, I have tried using the original battery, with no wires attached, just plugged it in (gave it an initial charge again) and the USB worked without any problems: TeraTerm can connect.
So the problem seems to be in wiring.
I have tried to connect the wires in different random ways (crazy, I know), but only one alternate way did worked. Although, phone did heat-up rapidly at the area, where it says "HTC Innovation" and phone's display showed "USB" even if no USB cable was connected.
So.. looking forward to some thoughts or any knowledge, of why is this happening, wiring schemes, or any other suggestions..
FINALLY! SUCCESS!! I've connected the wires from the sony ericsson's battery to touch only one pin on the phone, instead of two, as shown in the picture. The phone didn't turn on, as I've tried this before.
But then remembered that the same pins charge the original battery, so inserted the battery and VOILA! Phone turned on to the bootloader and the USB circuit wasn't blocked no more! Flashed the phone to WM6.5 now successfully and the original battery is charging, as I write this post )
So, if anyone got HTC smartphone dead, while flashing, let me know, will try to help you out, since I've walked through this hell myself
Thanks goes to karhoe, for an excellent guide for flashing, also dharvey4651 for an excellent guide on installing vista's USB drivers (got new PC, upgraded to vista) and last, but not least - the whole XDA-developers community for helping me out
1A Wall Charger Works!!
I've had the same problem discussed above. I was trying some of my own 6.5 ROMs, which by the way were getting stuck at the initial boot screen itself. Due to some unavoidable reasons and circumstances, the phone freely was left to itself at this exact state, untethered to any power source, for extended periods of time, during which it slept and refused to wake up again, all my pleadings going in vain. And when it did boot, it went into the tricolor screen conveniently and switched off in ten seconds. I turned to the net for help and found that any charger with rating above 1A would help in giving it the required juice. I didn't want to waste any of the 6 USB cables I have.
I got the original charger, which is an 1A charger, after 2-3 hours of searching my room (Hey, Don't be too hard on me! In the end, I got it, right? Actually, I use the PC for charging, and a smaller 550mA one sometimes-- both didn't work this time) and then, when I connected it showed the screen again. But this time, I found that it was capable of running it without the battery being present.
So, all I did was I kept the charger connected to it with the phone switched on in the tricolor mode and with the battery inside. After half an hour, I tethered it to the PC and flashed a proper ROM. And Voila!!! IT WORKED!! It was 2.45 in the morning!!
I guess the power from the 1A charger is enough for the phone to run and charge it too which is not the case in the 550mA one and the USB cable.

Glad to hear that it worked for you Unfortunately, it didn't for me (as I only have an after-market charget, not the OEM one, although it is 1A), so I had to search for alternative methods.
Hello, sorry for the bother guys have a problem here:
i have my atrix 2 and last night i leave it charging and fell asleep' when i woked up this morning the phone was completly off but it was connected to the power outlet.Now the phone does not boot up and when it does it just reach the att logo and shuts off all bye it self. By the other hand when i connect it to my computer it shows a white led on its top right corner but nothing happens.
i have done everything like taking out the battery, leavin it on the wall charger, triying to turn it on connected to the wall but with no battery, trying to boot up in recovery and the other ways but still nothing. i am very scared because it has no warranty

Sounds like you may have an issue with your wall charger and/or power outlet in which it was plugged in to. You may have a bad charger, but you should first try to plug it into a different wall outlet -one that is in a completely different room, just in the off-chance that something is wrong with the outlet you were charging from.
If this doesn't do the trick, you're going to have to find a way to get a charge to the battery while in the phone or by using a battery-only charger. There's not many ways about going about this easily, other than buying a OEM battery for the Atrix 2 or by purchasing a Battery-Only Charger. If you're feeling adventurous -and I STRONGLY CAUTION you with this, but there is a way to charge your battery. Please read, re-read, and read again THIS THREAD.
So, received my TF700T in the post today. Got all excited, went to start it up, and nothing....
Has been on charge for 3 hours now, and I still get nothing when trying to start it up.
The orange light near the power button is on, indicating the battery is charging, but no matter what I do, whether I hold the volume down with power, hold both volume buttons and power, it won't start up / boot.
The strange thing is, when I first tried to start it up, it wouldn't load, so I plugged it into power, and I got the ASUS post screen, then it turned off almost immediately (I presume as it had insufficient power). Since then, I have not even been able to get the ASUS post screen. If I hold the power button for 10 seconds, it will vibrate after 10 seconds, then nothing happens.
I have tried all the volume + power buttons described above, as well as trying to reset button.
Is the tablet DOA? Any suggestions for ways I might be able to get it started?
Try putting a pin in the pin hole above the HDMI.

Tried this already, and just tried again now. Nothing!
Its weird that if I hold the power button in for at least 10 seconds, at about the 10 second mark, the tablet vibrates, but nothing happens.
The charger light is now green on the tablet, and still nothing. Has been on charge for 5.5 hours now.
Unfortunately, It sounds like a DOA. It happens. Good to know now then 6 months down the road.

Exchange it.
Haha, good old DOA. Mine took 6 weeks and the store gave up and just gave me store credit.
Return it!
I had exactly the same: on first boot it turned off after splash logo and I needed to use reset button to restart again.
long pressing just makes it vibrate but nothing more
And when it started, it crashed and rebooted all the time. Sometimes it went black and I had to reset it again
My replacement works perfectly, so yes it's a semy-DOA

Mine bricked with the same exact symptoms after a week. Worked flawlessly up to that point. Waiting on the replacement to ship...

hi,
I was gonna open a new thread since my problem is based on charging but this thread pretty much is for the same use.
I got my tf700t yesterday through a friend visit from US. It has been nearly 2 weeks since he got it and he never charged the tab since he wasn't much of a user. So yesterday he brought it to me (i'm in TURKEY btw) and the tab was working pretty properly. But it's charge was near %4 so i plugged it on to its dock and plugged the usb charger to the dock via my PC. I just saw on the tabs screen that its charging so i left it there for like 12 hrs since it was its first charge. Then after nearly 12 hrs later this morning, i disconnected the charger and saw that the tab was off. I tried to turn it on but just like cjhod1 says, I got the ASUS post screen, then it turned off almost immediately. Different then cjhod1's case, no matter i plug on the charger or not my battery led near the power button is off for all times. So i guess this means it doesnt charge at all which was operating properly 12 hrs ago.
Strangest thing is my dock doesnt charge either. I tried every possible combination but couldn't manage to get it done. Even more strangely, after a one hour charging with nothing indicating it's actually charging (the orange battery led is off for all times) it managed to get a %1 of battery charge and opened. It managed to stay on for 10 seconds and then shut down once more for all.
It seems like a battery problem but what are the odds to lose both dock's and the tab's battery after one charge. And now that i'm in Turkey, and as far as i know, asus doesn't provide an international gurantee but only for US, i can't seem to get any service here. Unless any solutions to this matter occurs, i will have to ship it to the seller that i got from the Amazon. Every suggestions or helps appreciated. Thanks in advance.

The tablet CANNOT be charged via a USB port! Use the specific charger that came with the tablet. This will deliver the necessary 15V to the system to allow it to charge.

then how come i managed to charge it the first time i plugged it to the PC? And even if so, that is not any handy at all. I will have to carry not only the usb cable but also the adapter with me for all times to be able to charge the tablet. That is not an issue for ipad as far as i know.

It's not a big deal. It charges to full within 2 to 3 hours. Put the darn usb and adapter in your bag pack along with your tablet. It's not like it's a size of a water bottle or something. Charging through the usb is not ideal since it trickle charges and will take forever. Charge it through normal means first and see if it can hold a charge through your everyday use. If it does then your good to go. Then try charging again through pc. Honestly with the tablet keyboard combo you won't have to worry about not having enough battery life to last you the whole day regardless of what you use it for.

I got my tf700t yesterday through a friend visit from US. It has been nearly 2 weeks since he got it and he never charged the tab since he wasn't much of a user. So yesterday he brought it to me (i'm in TURKEY btw) and the tab was working pretty properly. But it's charge was near %4 so i plugged it on to its dock and plugged the usb charger to the dock via my PC. I just saw on the tabs screen that its charging so i left it there for like 12 hrs since it was its first charge. Then after nearly 12 hrs later this morning, i disconnected the charger and saw that the tab was off. I tried to turn it on but just like cjhod1 says, I got the ASUS post screen, then it turned off almost immediately. Different then cjhod1's case, no matter i plug on the charger or not my battery led near the power button is off for all times. So i guess this means it doesnt charge at all which was operating properly 12 hrs ago.
Strangest thing is my dock doesnt charge either. I tried every possible combination but couldn't manage to get it done. Even more strangely, after a one hour charging with nothing indicating it's actually charging (the orange battery led is off for all times) it managed to get a %1 of battery charge and opened. It managed to stay on for 10 seconds and then shut down once more for all.
It seems like a battery problem but what are the odds to lose both dock's and the tab's battery after one charge. And now that i'm in Turkey, and as far as i know, asus doesn't provide an international gurantee but only for US, i can't seem to get any service here. Unless any solutions to this matter occurs, i will have to ship it to the seller that i got from the Amazon. Every suggestions or helps appreciated. Thanks in advance.

Hi Bezendra, did you get it to work? I have the same problem. I'm in Vietnam, and whilst the tablet charges just fine, the dock seems totally Dead on Arrival and doesn't charge (no light, nothing). Warranty isn't really an option here so I need to troubleshoot this exhaustively before giving up. Did you discover the problem?
Speculation: I remember a friend who visited here once, and their externally powered USB hard drive didn't work in certain houses. I think it depended on the type of voltage regulator in the house. Did you discover anything similar?
Hello,
This is the first time I am using Android so please understand that I know basically nothing about it.
So I received a refurbished note 10.1 (software 4.0.4) with about 50% of battery left. I played with it like 3 hours and then updated to 4.1.1 (or 4.1.2), battery went down to like 10% so I plugged the charger in and kept playing. After further 30mins I realised my battery still goes down (8%). I had a quick look in Google and many people are saying that after updating to JB tablet takes very long time to charge or doesn't charge at all. I thought mine will charge slowly so I left it overnight plugged in. I woke up with 7%...
I tried charging it with a USB cable connected to a TV, in the first hour it charged to 8 and after that (about 3h) it stayed the same.
So the question is: Is it the charger, software or is it just a faulty tablet?
What I would like to try is to downgrade it back to 4.0.4 but I am not sure how to do that (or if it is safe) with such low battery level. Is it possible to downgrade when tablet is off?
Thank you

Factory reset or reflash the firmware JB you flashed .
But i would return to the seller has you have no evidence JB is the problem as you only had the tablet 3 hours .
Flash any firmware via Odin min requirements 30% battery to be safe .

Have you tried charging from an actual power outlet I don't believe that you can charge them via tv, pc or any other device only via an actual power outlet.
As far as roling it back to ics I believe you would have to flash it but don't take my advice on that one, maybe someone else could advise?
Also no I would upgrade or down grade firmware without a fully charged battery.
I found that mine was charging worse after jb update I actually factory reset it and its a tiny bit better, I still find though that if I want to charge it fast its best to turn it off and let it charge, I also noticed that the biggest culprit for draining the battery atleast on my device is Skype just having it running in the background drains it heaps.

Yeah.. but what if I can't charge it?
Can I factory reset (I believe that's via recovery mode?) when battery is almost dead?

I left it charging the whole night using the included charger (It looks like an original one) and as I said it only dropped by 1% (tablet was off the whole process)
From what I know it does charge through TV's and stuff but it just is a lot slower.
And I have no apps running, wifi off, gps off - everything off. RAM cleared
// After about 3 hours of charging through a TV it went up by 1%...
I left it charging through a TV because if a normal AC didn't help I thought it may be something to do with the charger.

Factory reset is in settings under personal heading its the backup/reset tab obviously make sure you back up your stuff first or you will loose it, this won't role it back to ics but might help. Also I have never found that any of my android devices charge via another Device only wall outlet they do maintain the power level there at but don't really charge.
Do you have another ac adapter I youncould use to test with try a different ac adapter if possible.
charging cable likely cause
I have had very bad luck with factor Samsung cables.. I would Use a different usb cable and wall plug usb brick.. make sure its output is equal to or above the original Samsung charger .
This is likely why the device was returned to begin with. As most of us know refurb devices are usually just open box customer returns. Often are just factory reset and resold .

It might work check the voltage to see if its the same and use your usb cable, they use mini usb I believe. Thats the other thing the usb cable that you using might be stuffed. The cable on galaxy tab 7 looks 100% but it doesnt work at all, as erica_renee said samsung chargers aren't the greatest.
I use a Belkin charger much stronger than samsung original
From what I've read, one review says that there is no way to use a S3 charger. + it has 1A
Apparently note uses different pin configurations..
I have no idea what to do now... :<
What about finding a galaxy tab charger?

Galaxy tab charger will work I have and I just use it for both without any problems, you could go to tandy electronics or radio shack depending on what country your in they might have somethingcheap that might work or the might be able to test the one your got to see if its actually working

Right, before I get one, at the moment Im trying to use iPhone charger with the standard samsung cable. I showed a red cross (what I would expect it to show). I then tried to hold the volume up while plugging it in (Ive read on one forum that it helps, not sure what it does but worth trying) and it jumped up by 1% - no red cross now... I have no idea what Im doing or why no red cross is visible.. ehh
//edit:
Guys.. this is working!
Another 1% in 15 mins.. It may not be much but believe me, Ive been waiting for that 1% for a long time
I'll give an update soon
//
Further 15-20 mins and it increased by 2%. Well, yay! I guess

Not good where did you get it, does it have warranty make em fix it and give you another charger
Hi all,
last night my n8000 stop charging. ..
I even tried the different chargers and also tried to charge thru pc...
When I connect with charger the beep sound come but nothing more and cross sign appears on battery icon.. and worst of all my n8000 not even recognized by pc even...
Any idea ?
EDIT : changed the cable and everything returns to normal
Yes, return under warranty... This is not right. It sounds like the usb connector might have a problem...
