[Q] Standard Dock not charging or USB connecting

So this is weird... Plugged my standard dock into the same mUSB cable I used to have my OG Droid's dock plugged into, then insert the Bionic into the dock. Up pops the docking selection etc., thinking all is good.
Couple hours later I noticed my battery was down to 40% while docked! (yay LTE battery black hole...) Of course, the only reason I noticed is because the screen had timed out as well (10min in settings, never turn off when charging). Of course, if I hadn't been charging the device I would have turned LTE off.
I then realized it also wasn't showing the USB connected option; figured maybe the cable wasn't in completely. Yet when I unplugged the cable, the Bionic gave me the "disconnected from charger, unplug charger to save energy" message.

Hokaaaayyy... mebbe the Bionic doesn't like my OG mUSB cable? But when I plug it in directly to the phone, bingo, charging occurs, and the USB connection options dialog pops up as well.

Think I have a DOA dock? I hope not because it came as part of a bundle from Costco; I might have to exchange the entire kit (phone, dock, car charger, car dock, battery charger dock) just to fix this!
<edit>So for some reason it looks like the standard dock just doesn't like working with computer USB ports. It can tell if the USB cable is plugged into a PC (tried my desktop and laptop both) but won't charge or USB connect. It does charge if I plug the USB into a standard wall charger, but obviously doesn't allow me to interact with the device.
I'm guessing this is "as intended" even though my OG Droid gave me the option of USB connecting when I used its standard/multimedia dock?

Wow. I'll go grab mine right now and test and report back. Same CostCo bundle purchaser here too, so....

Confirmed. Incidentally, I used a powered USB hub to try to fool the dock - no dice. if I connected the dock to power from my USB hub, it did not charge the phone, As soon as I connected to the wall charger, though, it started charging right away.

Mine worked fine for the first few days, but now all of the sudden, it docks, but will not charge while docked. It doesn't seem to matter wether it is plugged into a wall charger or USB. Wierd....

Correction!!!
I just switched cables and found out that my Wall Charger must have got fried with my recent power outage! It is connected through a new cable (through USB) and is working fine. It docks and charges. SWEET!!!
EDIT, EDIT, EDIT!!! - I just realized that it is not hooked up via USB Power, It is indeed hooked up through another wall charger. I have both on my desk at work and thought it was in the USB cable hooked up to my computer, but I was wrong. It is in fact hooked up to a new wall charger.

The standard dock sucks. I did the same thing, unhooked my D1 dock, plugged in this one and it will not connect USB to my computer or charge the phone, I have to use the wall adapter that came with the thing. Planning to use this one at the bed anyway, I have a HD dock on the way as well, that one better connect to USB b/c that's how I debug apps via eclipse, much easier to tap on the screen when it's docked and debug. Ehhh, Oh Prime where art thou!

Mine only works with the Bionic Cable... Not the original droid or Revolution cords...

[Q] Recharge via Computer USB Port?

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.
Sent from my HTC Sensation 4G using Tapatalk

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).

How can recharge batterry from USB link with PC

I don't know , but I think even if you were able to charge via usb it will took very long time in order to full charge it because capacity of battery is big

Need to make your self a universal usb charging adapter,look it up on here.
Works and been tested with 7.7 aswell!
You need to solder resisters 33k and 10K To the data and power lines...

Do you mean D+ and D- lines of USB need to be pulled up ? and which D line should have 33k or 10k ?

Link please .

yes thats the one..
(make sure you join the resistors to each other at the middle aswell.)
Look at the resisters you use and make sure they are both facing the same direction.My first attempt to do it failed and at first i thought it didnt work on 7.7
Then i noticed one resister was back to front.not 100 percent sure if this was the problem but after i changed this from looking at pictures online and comparing the pics to my resisters i noticed what end the 2 colored bands are at.the 33k one with the gold bands and the 10k one with dual black bands.
The end of the restister with the gold bands(33k) and Black bands(10k)
is the end that the power joins to.
The other end of the resister should have matching bands on 10k and 33k.
this is the end that joins to the data line.

once i left my turned-off 7.7 connected to my running PC for few hours, to my surprise the battery seems to be charged-up during that time

yup... its still charging... but slowly...

Actually you could get faster charging with that USB data cable when the PC has been installed with the proper drivers. The standard downstream port could deliver up to 500mA ONLY after the USB hub has negotiated power draws with the host interface. Otherwise the port might just deliver less that 100mA power.
Kies provides the suitable driver. You may uninstall Kies afterward and keep the driver installed.
In addition, PCs have two kinds of USB port — standard downstream port and charging downstream port. Some older PC would label them 'SDP' and 'CDP', but I found that most modern PCs don't distinguish them at all. As you might imagine, you could get faster charging plugging into a CDP than into a SDP.
FYI., those ports used in wall charger is the third kind of USB port, CP - Charging Port.

Hi!
After installed the Battery HD soft, when link with PC, That programe showing the charging time and progress charge. but still not sure.

I am charging via USB as we speak.
I am doing it using a standard mincroUSB cable (that I use to charge my GNote and SGS2) and added an adapter I got on eBay for my SGT10.1
You can pick one up here: http://goo.gl/EMzpJ
It's not as efficient as the AC charger but it's doing a good job and will get you by if you haven't got access to a power point.

Can use this hub to charge as well
This SIIG INC - SYNC/CHARGING HUB AND READER FOR GALAXY TABLETS - CE-H21112-S1 gives you the capability to charge your Tab through a computer USB port. Seems to work pretty good used it last night. Checked the net prices vary per vendor.

The connector on the 7.7 tab is exactly the same as on P1000. There is no trouble in charging.

My original cable came with the tab allows me to charge via USB @ my laptop, but the charging speed is very slow. So I prefer to use an external portable charger over this most of the time. Not sure if there are any apps or software that allows fast charge kinda stuff?

(help) Battery not charging

Hello,
I cannot charge my note, neither from genuine Samsung charger, nor from my laptop using usb. It shows dots for a couple of minutes- up to 15 I guess, but the green battery is not filling with its juice. After a quater yellow triangle with exclamation mark appears on the screen.
I am able to switch it on, while the dots are on the screen, but after logging it, message appears that my battery is low and I should plug in the charger (but it is plugged...), thank after a couple of minutes battery remains 1% and goes to 0% I asume as GNote switches off.
Kernel is 2.6.35:7-N7000XXKL3-CL793489 [email protected]#2
And Baseband version N7000DDKL1
I guess it is a software error, because it worked well for previous owner while on CM9 (or the previous owner lied to my and sold me faulty item ;( )
Is it possible to somehow flash it or change the rom to any other while having that issue with battery? I mean while seing that yellow triangle?
Things I did that did not help:
- tried to clean usb slot,
- took off battery for a couple of minutes so somehow reset the device
- plug it to laptop

mhm, had that problem too, but removing USB and putting back and it works.
did you tried another USB cable?
other thing I got while charging under Android was "stopped charging, battery temperature to high" very strange...
Sent from my GT-N7000 using xda premium

I can only charge it via my laptop, but it takes ages - 10-12 hours to charge....
Any ideas why travel charger (added to set) is not working?

Now, while GNote is plugged it is still draining the battery

Had similar problems,
I have 3 stock USB cables and 2 chargers - I can only charge via one of the cables, unfortunately my rabbit chewed it within an inch of it's life..
I bought a new USB cable, Which connects via data mode to my PC but will not charge when using it in PC or wall charger.. Shows connected and charging - but battery continues to deplete...
Fortunately as I have one working cable I try to keep both batteries fully charged..
---------- Post added at 04:53 PM ---------- Previous post was at 04:49 PM ----------
Could always try Dr. K's Suggestion:
Remove battery for few min
re insert and just plug in to charge.
Afetr few min try to switch on

I've had similar problems recently myself. I think in my case it's a bug in the CM9 nightly i was using.
Plugged into the charger over night, no charge on the phone. Reboot of the phone has fixed this for me. I updated CM9 yesterday and the problem is gone for me.
I'm using a SE charger and it works fine. Charging via laptop works great as well.

USB Port Busted?

Over the past few months i've noticed my USB port on my Nexus 6 not working correctly. Nowadays only certain cords work, if any, and it just wants to charge on USB. i have to jam the cord into the port with the palm of my hand to trigger something to make it say it's charging over USB. i might have to either get a new nexus 6 or send this one off for repair.

Unfortunately, the USB port is soldered onto the phone's mainboard. It really can't be "repaired" without replacing the most significant part of the phone.
While you could easily switch over to wireless charging (I strongly recommend this, since it helps the usb port last longer by not using it) to keep the phone working, the problem is that you won't be able to use a broken usb port for much, meaning you won't be able to deal with recovery or fastboot on it.
My first suggestion would be to buy a BRAND NEW usb cable. Try that. Most of the time, the problems are on the cable end, not the phone's socket. It is certainly possible, and even likely, that you have more than one bad cable end. They are *incredibly* flimsy. There are also, unfortunately, a lot of micro-usb cables that are... incomplete. They come with devices as charging only cables, so they won't even hook up the data lines. You probably have a few of those and don't even realize it.

But what about data transfer ?

I have the exact same problem, not the port is completely dead. I've not only replaced the usb port but also the strip between the port and motherboard but it still won't work. I'm using wireless charger for charging but it's twice as slow as wired charging also I want to transfer files to pc and install custom recovery to install custom ROM n root. But without usb port that is impossible.

I guess the last 2 options left are to dismantle the phone and clean everything n make sure all connections and flaps r in place n maybe replace the "ribbon cable" connecting the buttons and battery (yes for some strange reason doing this fixes the charging issue coz probably the ribbon cable also has charging cables in it)
OR change the whole motherboard by ordering one from Ali express which costs 3000 with shipping but the main challenge is to replace it with the old motherboard. This process if not done correctly could completely damage the phone and make it useless.
