My 18 month old Tytn is not longer charger via the wall chager or car charge. But strangely it will charge is connected to the PC. I have tried a few different wall chargers including the original one and also test the wall charger on other charge by USB plug devices.
I have done a hard reset and also re-installed the stock rom.
Any other idea's ?
Same strange thing happens to me since 2 weeks.
No Charge with power adapter, tried different modells.
No Charge in car
But Charge via USB from PC . And Activesync works...
Any Idea would be very helpful.

Same here, no fix, just dealing with it, hoping the charge by usb doesn't crap out.
A few months ago I receive a wallcharger from a friend who had a HTC TOUCH, as I inspected the voltage on my original TYTN II charger and the touch charger I figured out the touch charger would do the job, so I plugged in and for a brief moment the amber light go on, but almost inmediately it went of, so I guess it would not work with my phone.
But I rechecked the voltage and got me thinking what could be wrong, and after messing around a little bit with the charger and the usb plug I found out that for some reason if I plug the usb jack all the way down it doesn't make contact with the phone usb, so I have to plug it half way to make it contact and charge the phone.
Maybe that would be your case.
Good Luck.
in my situation the yellow loading light of the TytnII is even switching on when I connect the power charger . But even after being yellow=loading for a full night .
No Change in battery status

My Tilt had a loose Mini-USB connector thing.
:S
OK. After reading people having the same problem I decided to pull mine down and take a look. Expecting to find a blown SM fuse on the circuit board. To my surprise I did not find any SM fuses in that area of the USB plug. While I had it apart I noticed some damage to the USB socket, viewable from the outside without having to pull it apart . I re-assembled the unit and VERY VERY carefully tweaked the damaged pin (pin 1 in my case) with the tiniest sewing needle I could find in the sewing kit. I bent the gold color wire back into a position matching the other 4 and pulled it into a wall charger and it started charging. So the problem in my case was a damaged pin 1 in the USB plug visible from the outside.
Charging is done by the two outside pins.
For the pinouts check out http://pinouts.ru/Slots/USB_pinout.shtml Picture on the left hand side of the screen called MINI is the same as looking at the plug on the tytn from the outside.
While looking at the plug with a magnifier I could clearly see that pin 1 was collapsed into the plastic center part and would not be making contact with the USB charger when inserted.
I will need to take more care when inserting a USB plug from now on and reduce the amount of time I used the plug. I have been geocaching with my TytnII the last few weeks and it has resulted in a lot of plugging in each time when returning to the car. This practice will have to stop for me if I want to get more millage out of my tytnII.
When I first got the phone earlier this week, I could plug it into the charger in the wall just fine with no issues, it would just charge. Now suddenly it started telling me USB connected and goes to the MTP screen and of course locks up the phone.
I can of course bypass this by switching the phone to mass storage mode, but since I have Kies and use it occasionally, it would be nice to not have to switch that setting each time depending on my charging/syncing situation.
Why would it have not locked it up with the MTP screen originally when charging from the wall but now it does? The results are the same whether its plugged into the wall or the USB port on the computer. I have two Captivates bought brand new on a family plan, both do this now with any combination of chargers and USB cables, wall USB port, or car charger. Neither one has a common application installed since the other is my girlfriends who hasnt done much to it yet, so Im blaming the phone itself for now...

Interesting. I just checked with my BB charger and they dont do it using that charger, but they do it as soon as I connect the stock charger again.
Im wondering if its a voltage sensing circuit thats tripping due to the different voltages which should be applied - either wall charger or USB port. Maybe for some reason my wall chargers arent putting out enough voltage and its thinking its a USB port, but the BB charger is putting the right amount of voltage out?
Am I on base as to how it differentiates between wall or USB port? The number of pins obviously doesnt matter as all the cables have all the pins in them, unlike some charger cables which only have the power and ground. The only thing I can think of is that it uses the amount of voltage/current to tell the difference and create its reaction.
~T.J.
Sounds like a problem with the stock charger, maybe usb cable alignment. My iphone wall adapter does this with the samsung cable but the samsung wall adapter doesn't, same with my car charger from att. Also I have a $5 walmart car charger that has a cable that splits into both a mini usb and a micro usb that isn't a real usb cable, it's charge only. That cable has no problem on any wall or car adapter. I believe the phone detects if its connected by checking voltage on a data pin (just a guess really) so if a nonstock charger is used it assumes that it is a computer. But it may also be a data signal that is given off by the charger.

did you try a new charger and if so, did it work? I've had my captivate since Thursday and on Thursday it charged and everything fine, but then yesterday,
a) no computer I connect it to while recognize it, no matter what I have it set too and have latest drivers installed
b) if I charge it, after I unplug it, it locks up to black screen and I have to remove the battery to get it to work
c) I also have an in-dash touchscreen monitor in my car that has a usb port because it works with an ipod. I plugged the usb into to use it as a car charger, unplugged it, same thing
d) it did say usb connected after it was unplugged, but I switched from mass storage to ask on connection and it went away
so is an actual wall charger the solution?

and now I unplug it, and if it locks, it will not unlock, just black screen
I have to take out the battery and then only way to get it to turn back on, is to plug it back in the wall

I bought a Nook Color a few weeks ago, charged it to 100% over the wall charger, and after that I mostly used the USB charger since I haven't been using it for extended periods of time away from the computer.
Today I inserted the wall charger, as usual, upside down into the wall outlet at work. It charged for about 5s then the orange N went dark. I switched outlets, used a power strip, and took it home and still nothing. The USB cable is fully inserted. Now I can't get it to charge over the wall charger but I can get it to charge from my computer with just the cable.
It seems like the wall chargers are low quality in general, but is there anything else I could do to fix it? I live overseas and it'll be a pain to rma a wall charger.
Do you have any other device (iPod, cell phone, etc) that gets recharged with a USB charger?
As a sanity check, have you tried charging that device with the Nook charger?
If you try that and it doesn't charge, then it's pretty clear that the charger is hosed. The charger likely has a fuse inside. Whether or not it's replacable is unknown. I'd be very disinclined to try to open the charger. Unless you know exactly how to open it, you'll likely visibly bugger it up, removing the option of a return/replacement.
If the evidence shows that the charger is dead, I'd contact BN to explore options, given your situation.
sounds like you fried your brick (charger). You mention that you are overseas. You have to be carefull about placing devices made for US current into electrical outlets in other countries, as each local can vary the amount of current they feed into their lines. Were you using a converter from your charger to your outlet? Or does you current location use standard US configured outlets?
I'm overseas but I'm running off American power right now. The charger also accepts pretty much any overseas voltage available. Don't have anything else to test it with(mp3 player takes different voltage and I don't want to fry that) Probably blew a fuse ><
Guess I'll send it in for a replacement.
I got the 16GB Touchpad few days ago and since i got the one with an american charger i cant charge it yet (till i get the traveler kit).
My actual problem is that it doesn't charge through the USB port too. I left it for like 24-30 hours charging through the USB port (with the cable that came with the touchpad) and when i try to turn it on, it shows me an icon of an empty battery.
Is my usb cable problematic or it just that the touchpad cant charge through the usb port from a PC?
ps: every time i plug the usb it get a message telling "to reliably charge please use the charger and cable that came with this device"
I have the same issue with a 32 GB one. I received it brand new, factory sealed today and it is going back to HP. I called HP, the cable is fine, works with my HTC phone, it's the USB port on the Touchpad, it's loose and losses connection. HP is sending a box with prepaid shipping label and doing a warranty repair.
I really love the Touchpad and I am a bit disappointed with receiving a new device with a loose USB port. HP has great support and I can't wait until I get it back.

Unfortunately thats not an option for me (returning it to touchpad), since i bought it from Ebay (thats the only way possible for me to buy a touchpad from my country).
You had the same issue with the charger plugged in the usb cable as well?
What sort of power source do you use, if not the charger.
I've tried to use a computer, but it does not look like it's charging, but data transfer work.
I tried with an iphone charger, that sort of work. It complains about not getting enough power (iphone charger is 5,0V while the hp charger is 5,2V)
Bottom line. Use the original charger, just buy an us adapter. It works great.
There is another thread here sonewere discussing chargers for non US owners.

Im trying to charge it through my PC using the original cable that was in the box (tried it in a USB 2.0 port) and im getting the 'try a reliable recharging source like the USB cable and the charger that came with your touchpad'.
I also tried charging it with a 5.0V 200mA phone charger but it didnt work either.
Shouldnt it charge even a bit with the cable? im trying to charge it for 2 days now

Yes, tried the wall charger, then pc, a different usb cable, all had the same result. When I plugged in I could feel the USB port loose in the Touchpad itself, it had a bit of play and if I played gently on it, it would begin to charge or connect to the pc. When i let go, it disconnected from my pc and then gave me the charging error message. I purchased mine from an e bay store and it has a warranty for 1 year.
I would be happy to help you with yours, if you want to ship it to the US, it has a warranty from the factory. Pm me if you'd like help. I am certain that shipping to and.from US could be costly but I am willing to help.

Mine will only will charge from official HP chargers. This is much like my old iPhone 3g before all the generic manufacturers caught up. I suspect that the voltage and amp requirements are tighter than the USB specification, so it will be a crap shoot if you use non HP chargers.
With that said, HP has 30% off all touchpad accessories right now. Combine it with the cupon SAVE15HP

Don't worry over that, I can get what you need and ship it to you.
Also, in speaking to HP, any USB charger in the US works, they're considered universal.

you cant charge the touchpad using a computers usb ports. it doesnt draw enough power. the voltage of the charger doesnt really matter, it needs at least 2 amps or it wont charge the touchpad. cell phone chargers usually only draw 1 amp or less and usb ports only .5 amps.

That is absolutely not the case.
I have only charged mine once with the AC-USB thing and I have been using it since I got it the first day of the sale. I use mine all day long and only charge it occasionally via USB to PC connection. I use the original cable from HP and another one from my Samsung Mythic (work and home).
The message that you get when you plug it in is misleading but normal on a stock TP. However there is a patch in PreWare that changes it to just default to charge and not bug you. Anyone who intends to use this thing at all with WebOS needs to get PreWare installed. In fact, some time spent at precentral.net would benefit any new owners. You will learn A LOT more about these little jewels. I spent a few hours reading stickies and interesting threads and learned a great deal.
If it is really plugged in (and you will know because your PC will tell you) and you get no charge, you have a problem. It should charge on or off while plugged in - mine does.

Now to be completely honest - the first charge I made out of the box was with the AC adapter and I left it in overnight like I had been told.
But since then I have never used the AC plug and I have let it get down to about 20% or so but no lower.
It very well may be that from a DEAD state, it requires the extra amps to jump start it, but as long as you have that initial charge it is covered by the lower amperage of the direct USB-to-PC connection. I'm guessing it came with a fair charge and you burned through it without ever plugging it in to the USB.
Bear in mind that not ALL USB ports on a PC are powered the same either. Older USB 1.0 and 1.1 are crap for power. Front or top-mount ones also may not have as much juice as the ones in the back directly off the motherboard. Look at portable hard drives, some come with a double-header cable to use two low-powered ports. I know my top-mount ones will not power my 1TB 2.5-inch drive, but the ones in the back do.
However, I am really surprised you can't pick up a standard plug in USB adapter for your country for a few dollars (equivalent) for wall. Jeez they sell them at the dollar stores here now. I don't know if a car adapter would output enough to do it but that is another idea. If you can get one, you should be able to bring it back easily enough. The 2 amp adapter does charge a lot faster.

LOL, I am really in a rare mood as this question has bugged me a little. So I decided to find some straight poop. Here is the best description I have seen anywhere.
http://www.maxim-ic.com/app-notes/index.mvp/id/3241
If you don't want to read it, the gist (as I understand it) is:
At 5V, the USB ports in a PC have to be able to source (provide) at least 500 mA (.5 AMP). However, depending on how your motherboard is provisioned (MOSFETs and diodes) that is limited/controlled.
The spec though, does allow as much as 5A to be provided. In fact, 2A is not uncommon if the other ports are not loaded.
So you could try unplugging all your other USB stuff or try another computer's USB ports.

Given that the HP charger has a 2A output, odds are that anything much below around 500mA isn't going to charge the device, or at least not at a rate that'll offset the drain while it's running.
The USB ports on laptops often won't supply enough current, particularly if there's other devices on the same bus. If you plug it into a powered USB hub then you should be in business as they should supply more like around 1A generally.
My Touchpad charges from my laptop USB port, however it is slow. I am getting about 8 - 10% charge per hour. The screen needs to be off though, otherwise there is no noticable charging happening.
Mine is not charging with USB laptop at all. Need to use wall charger
I have XRON VB2.8 on my two touchpads and both show battery charging symbol when they are connected to computer via USB and yes the they charge very slow.
FYI, can't remember if WebOS / Govnah tells you what the current amps being used is, but if you are on Android tools like Elixir 2 tell you how many amps you are either discharging (-) or charging (+). So depending on what you are using (wifi, bluetooth, # of widgets, running applications, screen brightness, overclocking, underclocking, etc.) YMMV on whether or not you can charge via usb connected to your computer.
So if you are discharging at a rate of -750 mA connecting to a usb port on your computer will still have you discharging at a rate of -250:
Code:
[COLOR="Red"]-750 mA[/COLOR] + 500 mA = [COLOR="Red"]-250 mA[/COLOR]
mine charges in the usb port, but only if I turn off the screen or turn off the touchpad completely. my ports only provide 500mA, and with the screen off, the touchpad draws about 50mA, so it can charge at about 450mA. With the screen on, it draws about 760mA, so even when it's plugged in the USB, it is discharging at a rate of about (760-500=260mA).
So I have a streak 7 wifi only model. A few nights ago I upgraded manually to HC 3.2 with no problems. System seemed normal and everything in life was good. I forgot to charge my streak and when I woke up it was dead as expected as the battery was already low. So I plugged it in and let it sit for a few hours. Didn't even occur to me the light never came on for charging. So I figured I must have forgot to plug it in. When I looked it was plugged in correctly. So I plugged it in yesterday and let it sit for 24hrs and still no juice in the battery. I have tried unplugging the cable and reconnecting. I have tried using the power reset pin. I have tried different usb charging adapters. As I said it is dead so I can't get into the recovery menu to perform a factory reset. The power cord I got was just shipped to me on Tuesday Oct. 4 from Dell and worked fine when I first used it. Any help would be greatly appreciated.
Try this as it may not be the cord but the converter itself. Plug in the USB to a computer that is ON and RUNNING. In other words...not in sleep mode. Let it sit for a few hours and also note if the light comes on. It just may be the converter may have gone bad. Also try by resetting in using a needle and push it in the small hole to reset it.

Do you have the original charger and the cable that was received from Dell is the right cable? I had one shipped from China and all it does is trickle charge, the original cable from Dell that came with my unit charges it in less than an hour on the same charger. Make sure your charger has at least 2 Amps output, cheap 1 Amps will only trickle charge

I want to thank you both for your responses. I have had it charging for about 3-4 days now and it has not worked no matter what I try. I called Dell and they are sending out a new unit. It is scheduled to arrive today.
Plug a charger and force power off with a button(A small hole) next to SD card. Mine sometimes freezes not responding after screen off so I just do this trick, power on it and OMG it works
Cheers
Thanks - this worked for me
