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?

I plugged in my phone to charge it this morning and all of a sudden when i connected it to my wall charger it went into USB Debugging mode? This is a first for me and it kinda scared me a bit. I then unplugged and plugged it back in and it went into charging mode. Can anyone explain this? Has this happened to others?
I believe if the charge current is low, such as 500ma, the phone assumes it is connected to a computer. Doesn't mean anything other than a slow charge.

thanks for the reply.
im sure it was just a fluke. ive always charged it in this wall outlet. i replugged it and it works fine
has this ever happened to anyone else?
This happened again. Can someone help me out here?
Happens to me all the time. As the poster above mentioned, shouldn't be anything to worry about.
You can turn off usb debugging if it bothers you or use a different usb cord as some have a tendency to do this because they reduce current flow too much

That happens to me when i try to use the iPhone charger.. I'll try to jailbreak it..
Download "Spare Parts" from Market. In the Battery Info section, you'll se if the phone detects your charger as USB (PC, below 500mA) or a Wall charger (700mA)

So if it detects my wall outlet to be below 500mA then the power going to that wall outlet is low?

Let me test.. But my iPhone charger is 1000mA!! And my phone detects it as DC, acording to Spare Parts (USB), and if i switch to the original charger, it turns into AC..
If the phone controls how many mA/Volts can receive, and the charger is detected as DC, it will be charging at the same speed as if you use the PC USB, no matters if you uses a 200000mA charger...
BTW, sorry about my english

The charger has wiring that shorts the data lines - this tells the phone it is a wall charger and not a usb port - the usb port carries data, so the lines are not shorted. This controls the amperage - If it shows AC - the phone detects the shorted data lines and the phone draws about 700mA. If the phone does not detect the shorted data wires, the phone only draws about 500mA. In all cases the voltage is 5V DC.
I have a 2A car charger. With a regular cable (non-shorted data lines) the phone thinks it is on a USB port. I short the data lines and the phone says AC charging.

I am using the regular charger that came with the phone. Does this mean the charger is faulty?
I get this all the time. Probably because I'm using the little white USB to wall converter from my old iPhone. I still get a good charge, though I've noticed it charges about 2x faster if I turn it off and use the black charger from Samsung. That way I get about 20% an hour, otherwise about 10% an hour.

If you are using the charger and cable that came with the phone, and the phone settings page says you are charging via USB and not AC - then either the charger or phone is faulty.
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.

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 this is my first motorola and I had heard of the issues they have with non motorola chargers. Now I am experiencing it first hand. With the same ac charger I have charged many phones with and is capable of 1 amp output (D4 charger is only rated at 850 mA) my D4 struggles. With the device off it charged painfully slowly. While on it cannot even charge. It discharges while plugged in despite the charging indicator and reporting "charging (AC)" in status.
How does it know it is not a moto charger? Is it just about the resistance between the data pins? For most other phones shorting the data pins on the charger indicates to the phone that it is a high current charger and not a computer USB port. Is there a similar trick for motorola phones? I would rather not have to purchase an overpriced moto oem car charger. I have a perfectly fine 1.2 amp car charger soldered directly into my car's 12v system behind the dash. Can I make it work?
Thanks!
On a regular basis I successfully charge my D4 using both a charger from a Samsung Reality feature phone and from a B&N Nook Simple Touch, in addition to the one that came with it. I've also used a variety of car chargers.

Actually, so far I have only one charger that had any trouble charging the phone (it was a $3 charger with 2 USB ports), but the $3 charger with ONE USB port works fine, as does the Nook Color charger, Blackberry charger, and Samsung charger I have tried it with, as well as both my old car charger and Lenovo's always-on charging port on their laptops.

Not sure how it knows one way or the other. I've successfully used a few LG chargers to charge my D4. The only really hickup I've ran into is the usb cables from those lg chargers won't sync data to the phones when plugged into a computer, they'll still charge off the usb port but won't read as a usb connection to the computer.
Heh, captcha is trynply.
Every charger I've used, including an old charger for an EN-V, kindle, supplied, and various other phone chargers works just fine with this phone. Probably have a bad charger, guy.
Thanks for the replies. I guess I was wrong. My modded car charger works just fine. I guess its just time to retire the old charger that I have been using. I think it might be my old nexus one charger.
A more important question would be does the thing charge over computer-bound USB ports?
When you're without a charger, but there's a USB cable that fits your phone, sometimes a regular USB data port is the only that is around... even though it might take a really long time.
Try a computer bound USB port, then try your actual charger, again. Or do the hard reset (vol down plus power, hold until it actually does it), which is just like pulling the battery.
See how that goes.

It does in fact charge via USB port. In fact, it has a 'charge only' mode. Depending on how much juice your port puts out, and what you are doing with the phone, it will charge slowly/not at all, though.
from my experiences, the droid 4 will not accept lg microusb cables, the charging bricks work tho. i use a blackberry microusb on mine along with a Logitech and the stock moto ones. 1.2 amps is a bit high but not crazy sounding. personally, I charge at 1 amp.
after years of not issue, yesterday my note stop charging in the outlet chargers, I have several all do not charge it but have no issues charge my wifes phone.
but I can charge the phone with the same orig cable when the usb is my computer and not the outlet.
any clues why my phone will charge in my computer with same cable but not in orig outlet plug. please tell me I do have to have my $2K high end gaming desktop on just to charge my phone in its usb slot.
I cleaned everything, it is a new battery

I have tried 4 different adapter/cords combos ( just in my house) none of them charge my phone in an outlet - all work with my wife's smaller samsung in output. so weirdly only a direct usb with the oem cord to computer works ( in both my desk and laptop). so weird. so annoying.
You have to buy a new charging port, and the board that comes with it. This is a link to the part you need. If you search "n7000 charging port flex ribbon" you should be able to find other places that have it. http://www.etradesupply.com/oem-samsung-galaxy-note-gt-n7000-charging-port-flex-cable-ribbon.html
So i am having this problem, wonder if anyone else is also. I reported it to samsung.
The problem is when using a car charge my phone will say charging like normal. BUT then it will says "powering connected usb device".
It will say this the whole time it is charging.
Its a 5v 2amp charger i am using a micro usb cable with the included usb c adapter.
I use the this same charger for my s7 edge without problems.
Now the kicker here. Once i unplug the note 7 from the charger it will keep to saying "powering connected usb device"
The battery icon will flip between the power out icon and normal battery.
The first time it did i had to reboot the phone so it would stop.
The next time it went away after a few minutes.
I havent try using a usb c cable, but will later today.
Just wondering if anyone else is having this problem. Its probably OS related or have something to do with the adapters.
Just wondering if anyone else has this problem
The included micro-usb-to-usbc adapter seems to inhibit the charging speed. I used the adapter with an official Samsung Micro USB cable that came with my Note 5 and plugged it into a Samsung fast charger and the charging takes forever... Maybe you're experiencing a similar symptom?

Its possible. Today i drove for about 20mins and i didnt have this problem. It charged but only went up 3% more. I should of gotten at lest 5-6% with that charger (amount i would of gotten with my s7 edge, same charger in cable)
I will do a test today with the usb c cbale plug right into the usb adapter. I only have the one for the time being
Well the problem is still here.
My wife gotnher phone and the same thing.
She needed to charger her phone.
Plug it up and it says chaning connected usb device. Just stays on the screen for a while then goes away.
Now we got out the car and turn the car off.
Then phone lit up and says powering conntect usb device. Then my rasio started to boot up and ended up in a boot loop as long as the phone was connected.
So thephone was trying to power my car through the usb charger.
This is something samsung should fix asap. There should be an option to turn this off.
Ill have another chat with samsung
