Dell Venue 7840 not charging (android) - Dell Venue

As the titles says, my tablet stopped charging. I already had this problem while it was under manufacturer's warranty and they fixed it for me. Now, with the warranty expired and all, I have no idea what to do.
I have looked everywhere and I can't find anyone who even knows how to fix this, let alone finding the spare part needed. I guess I'm just venting and asking for advice at the same time. Any pointers would be greatly appreciated.
Many thanks!

Bummer. Probably possible to resolder a micro usb power jack. Had it done on my HP Chromebook 11. Go to your local computer wizard shop.

Kinda sad

Well my X10 usb port is broken and won't charge, so I decided I might as well get a new phone (I looked up trying to fix it and etc but came up with nothing). I bought the phone unlocked and had it imported back when it first came out so no warranty for me. Well anyway the point of this is I decided I don't want to spend so much money right now so I'm gonna stick with phones provided by my service provider which is T-Mobile US, so at the moment I have the choice between the Samsung Vibrant & the myTouch 4G and I just wanted to hear some opinions on that (I don't really like physical keyboards so the G2 is out) I'm still going to do my own research but its always nice to hear other peoples thoughts.
you could just buy a portable charger for the battery...
RS Online has micro USB-ports, and if you fear that won't look any good it's a good opportunity to hack it into wireless charging:

Um a portable charger wouldn't be able to help me if I need to connect the phone to the computer to do things like flashing and etc
Have you tried another charger? Had the same problem and a new charger worked, phoned my provider they sent me a replacement and I just swapped the charger.

Yeah tried multiply different ones. At this point I know its a fact its the usb port because its jiggling.
So what's your plan with the broken device? RMA, selling as defective, or leaving in a drawer?
If the latter then try fixing it first - it's not the first phone with a loose micro-usb port.

Same question from me. I have the USB jig for the SG2 and wonder if it works and will reset the binary counter on the tab?
I have the Samsung TAB USB-adapter but I need an additional male USB-female micosub adapter to try the USB jig out, and before I do try to find one I wonder if someone has tried it?

Hey, well I would LOVE to have someone else repair it for me but I can't, I called samsung they wont take it because the unit is from USA, i can't send it to USA because I am not a US resident, I can't send it to Service Absolute (even using my own money) becuase they don't repair non-canadian units... So what can I do?
Flip it on Craigslist?
EDIT, nevermind, I misunderstood the question.
Great Question

I was reading this thread and I have been looking for the same answer for my Note 10.1 2014 edition. USB Jig without seeing the tech explanation and drawing upon my own technical experience clears some memory locations in flash binary that hold values for tracking flashing, maybe the boot loader and some other values. If I could see or find the tech manuals I might get a better understanding. However, this USB Jig is a technician tool of convenience and necessity to gain access and repair electronic equipment. Basically, it shuns or shorts across two pins in the USB with a load (resistors) so it isn't out of control short and manages the amount of juice or some electricity to clear those registers and reset the electronic device safely. The real technical question are all Samsung electronic circuits in phones and tablets access the same way, or is there a different pin configuration to be used, or a different sequence of steps to prep or follow up with, or almost finally can't work as the USB doesn't access the same parts of the electronic circuit. Lastly, if an experiment is done to just go ahead and use the USB Jig. Will it be a harmless attempt or will using the USB jig damage the circuits in the device? The last question is a show stopper, Dirty Harry type of question. Did you get an answer yet by experiment or by someone passing on the answer from their experience. Someone knows this answer and I am going to have it. This is how open source, crowd sourcing works.
BTW you question is valid one as now that Samsung Tablets are all on USB and people are going to continue to want to experiment with ROMS and modifications. So this answer will need to be answered in the near future. Samsung benefits from their products ability to be hacked and modified as this one of the consumer draws to buy. However, now Samsung is gaining more and more commercial success they may attempt to limit this activity. The downside for Samsung is that they end of having to respond to experiments gone bad, bad business for them. So hence their service attention to the flash binary "got ya trap and take a penalty, warranty voided", to limit those activities.

[Q] G Tablet Dock Help Help

Hi guys, wonder can anyone help me. I purchased a dock for the G Tablet from a company in Chine a few months ago. I only got round to trying it out recently and the results where not good.
The dock charges the G Tablet when the PSU is connected to it, but that is all that it does. The USB port does not work, the pens light up but the G Tab does not see them.
The network port does not do any thing when a cable is plugged in.
The HDMI also does not do anything.
I have tried it with several different versions of Android including the T&T that was on the G Tab originally.
Am I missing something ? Do I need to install certain software of certain Abroid version ?.
It wouldn't usually bother me but the dock cost me over £35 and I do not want to purchase another until I am sure this one does not work. Any help would be greatly appreciated.
PS Keep up the great work, I love this site and have tried almost every new OS that has been put on it
No specific software should have to be installed. It's supposed to just work, so I'm thinking that it's bad hardware.

[Q] When docked w/ lapdock thinks its hdmi only, goes into webtop, cant use touchpad

Hey guys, I did a search for my issue, but found no relevant solutions.
I am using a much older ROM, Gingerblur 3.1 with v 1.83 and I just bought a new lapdock. The funny thing is, all the instructions came in Spanish, but I don't think that would necessarily be the issue. The weird thing is when I open it with phone plugged in, it does not go into lapdock mode, but on the phone I get prompted to go into Webtop or multimedia mode. I go into Webtop mode and it looks like how the lapdock mode should look, however, I can not use the touchpad or a USB mouse that I plugged in. However, on the phone screen itself, it shows a mouse pad essentially, and option to go to keyboard, so it thinks its only plugged in via HDMI to a screen only. The funny thing is though, if I do not turn the phone screen on by pressing the power button, it says No Signal Input: HDMI, which implies that it knows a phone is connected via USB since that screen does not come up when the phone is plugged in. I am also not using a case so I know it is firmly plugged in with no obstructions. Someone else had the same issue with a different ROM in this thread:
http://forum.xda-developers.com/showthread.php?t=1598132&page=2
Please help! Is this a ROM issue? I was planning to switch over to the NottachTrix4G ROM, but it seems the same issue may be occurring there. I think I still have 30 days to return it, but I would love to resolve the issue. Any thanks would be much appreciated.
I had this problem. You buy from onesaleaday? Sent mine to Motorola for repair. Defective USB connector. Thread is in accessories forum. Moto couldn't find serial number in their system, but they took care of me.
Probably your documentation is in Brazilian Portuguese.......not Spanish. Look same but not same.
It is not a ROM issue.

It is in Spanish for sure, I can read Spanish. I bought it on Amazon from some reseller who had only one in stock from Bakersfield CA, which is a 2 hour drive from me. Thought it was a good idea. Should I return it? Or can Motorolla help me out with a product I did not buy from them?
I really feel like the USB is not defective, or that it at least is detecting my USB connection since it prompts the message about NO HDMI cable in place, which cannot be achieved unless the phone is plugged in. Obviously you can't test with just the USB connection alone and no HDMI, but my IT spidey senses are tingling. Could you link me to the thread you were referring to? I was looking for it but I could not find it.

Mine was doing exact same thing. There is a known issue where connectors, especially USB in lapdock do not stick out far enough to make a good connection. I called Motorola, they arranged overnight shipping both ways, no problems. Had it back in a week fully functional.

Turns out mine starts with a serial number starting with a B, but all the localization is for Mexico according to the packaging. Gonna try to see whats up with a warranty.
Edit: My B serial number was in the system, and I have files a warranty replacement request, thanks so much for your help CaelanT!

Glad I could help.
As an added note for anyone else, the shipping is handled better if you have them set up the RMA over the phone, and do not set it up yourself online.
They actually told me this themselves when I called them. I have to say, I was pleasantly surprised at the customer service being as good as it was.

however, this solution actually resolved it for me, I should have trusted my IT sleuthing skills because I knew the USB connector was working since it was charging properly, let that be a lesson to anyone else searching for a solution, if your phone is charging while plugged in, the USB connector is working properly, this is probably related to the fact that I am using nottachtrix4g which I have seen mentioned before as an issue
I had posted previously that not charging was an indication of USB failure. None of the normal USB functions were working for me. My apologies if I sent you down the wrong road.

I sent mine to Motorola as well and got it back with a message that there was not a problem with the device. I was running stock Atrix when I first tested. Nottachtrix didn't work for me either.
I was under the assumption that the Lapdock was simply a HDMI monitor and USB Host. Have since installed CM10 (epinter) and still experiencing the same issue.
**Ninja Edit: Yes I'm a noob
I connect my lapdock and it works. After a few minutes the display still works but the keyboard/trackpad are unresponsive. Any ideas?
Just wanted to post up another suspected failure - i just received my atrix(Hebrew edition) lapdock from Ben's Outlet - no charging on the usb port with my bionic (dismantled the dock location to connect the wires before modifying the casing)
I'm guessing after all the reading in the forums I've done that the only option is to warranty claim with Motorola ?
I also noticed i have no serial sticker on the bottom(but do have the hologram and another model number sticker) - I'll have to check the box for the serial unless there's another way to get the serial number?
Thanks for posting up this discussion! Saved me hours of banging my head against a wall, i really wish the thing was working though...

[Q] Root Galaxy S2 At&t without computer

Hi ,
My galaxy S2 is have a problem .... whenever i connect it to a power out / computer the power supply starts fluctuating because of which i cannot use my usb port on my phone to charge so i take out the batter and charge it with an external charger.
Is there any way i can root my phone without connecting it to my computer ?
And one more thing is there anyway i can get my USB port to work ?
I bought this phone when i was in USA but after i shifted back to India this problem started occurring.
The service center people cannot repair or replace it as its the USA version and not the International version.Some parts of International version are not compatible with this US version according to the service center guys.They also said that its IC is short circuited but i think when IC is short circuited the phone does not give display but its working all fine.
Please help me with these 2 things -
1.Rooting my phone without connecting to PC
2.Getting my phones USB port back to work
I'm guessing your USB port has a problem check out this thread
in my case the phones not charging.....
The phone reboots when the charger is connected
The answer to your question is no. Unless I've completely overlooked something.
You will need a good usb port to be able to root the phone. There have been a couple of people who have reported that they successfully replaced their own usb port, and say it is relatively simple to do. It may take a while to get a replacement port, but since the part is small, shipping to India should not be prohibitive. Replacing your own usb port seems to be the only practical fix for your problem.

where can i find a working USB port ?
Google it. Not being rude but damn...
If you have a question about when the next CD by your favorite artist comes out, you google it right? When you need to know where to find which site has the best price on that CD you google it, right?
Use that same logic here. You need a part, google it.
Also, eBay has been known to have items people want to sell that anyone can bid on. Knowing you need it shipped overseas, it would be good to make sure the seller will ship it to your location before buying it.
(Searching these forums will present you with the answer as to which part you need to look for)
