TF701 USB Cable Connections - Asus Transformer TF701

Hi folks,
I had one of my charging cables recently fail. Opening it up, and I could clearly see the issue (a broken wire - the black one). The problem was that I could not clearly see where this wire should be soldered. I couldn't find any info online, so I opened up another cable to see what I should be doing, and thought I should share it here.

Charging fault?

For a few days my phone hasn't been charging, and at first I thought it was a problem with the battery, but having bought a new one I've realised that when I tilted the charger to the left it would charge, but when it's just left it wouldn't, so I guess a bit of a miss-alignment.
Anyone got any ideas how I can fix this problem?
Cheers, nathaniel
try another cable and make sure it's the one that came with the phone. you should have a usb one and a ac adapter. if both are like that then you need to warranty it out.
Yeah, Ive tried it with the USB cable and the charger, I got the same result. Is there no quick fix, I'm going abroad in 9 days and quite need my phone...
There are a few discussions on bad USB connectors in these forums -- searching might provide some things to try.
From what I can remember, it's possible the pins in the connector (on the phone side) might be bent out of place -- you might want to inspect them with a magnifying glass and try to carefully bend them back if any seem out of place.
It's also possible that the connector itself is broken -- in which case you're looking at a service call.
this seems like the problem i faced. i was also facing the same problem and i read the forums here and found it as a usb port issue. so i slightly bent the usb port so that the contacts are aligned and then it started charging
Hey I would also recommend trying a new a new charger again because I have had my share of faulty chargers. Last time I had a problem charging was with a brand new cable that did not work right at the box from At&T and thought it was my battery until i tried another charger that worked. I would suggest trying the charger that is not working on another phone and see if its actually the charger or if it is your phone that is not working.

I think it is to do with the pins in the connector.
I had a search but I'm not very good on forums and I can't find anything of any use. Does anyone have a link?
Just look at the last few pages of topics, you should find something... there are threads about broken USB at least once a week.
One common conclusion is to avoid using USB cables other than the supplied one as their
plugs are a little thicker and tend to deform the phone's plug over time (I admit I always use others though, and as a result do sometimes need to wiggle the cable a tad and not move anything anymore once the connection is established... ).
I once dismounted my Hermes and tightened the plug back a bit, it helped, I've never done it with my Kaiser yet though. If you're not used to dismantling and fixing devices I'd recommend returning it for repair indeed.
I had a the opposite happen, it would charge but no data connection with my pc. If you look at your extUSB port on your phone, see if the black plastic tab is cracked (which was my case) or if the pins are shifted. whatever the issue, its obviously hardware related, take it to an At&t service center tell them whats wrong and if your in warranty they'll change it on the spot.

He got the same result using his USB cable so that would rule out the charger.

Im in England, took it to the T-Mobile shop, the service was rubish and without even looking at it they send I should send it off which would take 2 weeks. There is a crack in the black plastic tab

[SOLVED] USB Charging/discharging Issue

Recently I had this issue and god's thanks i was solved it (thank you google you too).
Symptoms:
Suddenly my phone was not able to detect that it was connected to the wall charger or USB cable to a PC, also yes charged if it was off or rebooted with the cable conected, but was never recognized as a storage device.
Believing that it was a brand new firmware bug try prinmero check permissions and then flashing it with a newer version, but none of this resolved, so I decided to google a bit and there I discovered that I had this probelma many people with various phones and that the service technician always gave the same excuses, overall the team had been wet and had to change or FLEX cable or connector microUSB. Some home made repair also I found include welding a resistance in the USB connector pins FLEX Cable. Too nasty for me but i starting playing with te idea..
All this things smells very strange to, it was not possible that so many phones of different brands have the same issue. I continue reading until lukily I found many people talking about this solution, and it's works for me.
Solution:
Look at the bottom of your phone and note that you male usb port is bended down (screen side up)
1.Remove the battery.
2.Use a pin/flat wire cutter to clean the usb port, also try(very gently) to push the tongue of the usb port upwards (towards the screen.) Do it carefully and try to let it in an horizontal position
Problem Solved!
I hope this info will be usefull to anyone, see you in space

[Q] Issue with Micro USB port

I'm having a bit of an issue with my usb port where I need to push the cable upwards (if you are facing the phones screen) in order for the phone to begin charging. It also is taking a little longer than normal. I have tried a different cable as well with the same result.
Is there anyway to repair the usb port on the HD7? I just took the case apart on the back, but the port is still shielded. Is there any instructions out there on how to replace this port?
Iron soldering or a new board, your choice.
try with the soldering, if that fails, a new board must be bought, it cost around $25-$35 online.

USB connector failure - good thing it wasn't plugged in

I just bought a new Nexus 7 (2013), it is about a week old.
Last night I left the supplied ASUS charger and micro-USB cable plugged in overnight (fortunately the cable was not connected to the Nexus.) When I woke up this morning the micro-USB plug had literally melted, with plastic oozing out of the plug housing and through the plug itself. Had the cable been plugged in it would have destroyed the Nexus USB connector. I've seen several reports on the web of this scenario but none with a clear explanation of where the "fire" started. See the attachment.
Does ASUS have a problem here? In any case my plan for now is to use a wireless charger, it is too scary to think what would have happened to the tablet had the cable been plugged in.
I've opened a case with ASUS and they've asked me to RMA the cable so they can inspect it.
First off; post this in the right section. The 2013 folks would want to see it
Second.. Is there something in the USB cable on the 2013, like an LED, etc? What in the world could cause such a short in the plug of the cable like that? Scary.
Sorry, I didn't notice there was a separate topic for the (2013) Nexus 7. I'll replicate my original post there.
There aren't any components on the cable other than a USB Type A male connector on one end and a micro-USB male on the other.

Galaxy tab S5e pogo connector pinout

Dear all,
Just wanted to avoid spending some cash on Galaxy tab S5e stand. So short research on net show some pinouts of pogo connectors, and seems that Galaxy tab S5e uses USB pins .
So took multimeter, and found that first pin (counting from USB socket side) is GND.
Number 4 is 5V . Middle two I guessed are USB D+ and D-. But whatever combination (#2D+ or opposite D-) no success. Tablet is charging but in slow charging mode (seems to be 0,5A) . That is not so bad for me , as night is long enough to charge full easily. But anyway I would like to know what middle two pins can do. I saw on net some suggestions to use resistors, so tablet would try to charge at 2A , but none diagram works. To clarify , I have official charger and via USB cable , it charges fast.
So finally question... Do you know how to make USB connection via pogo connectors (so tablet could recognize charger, and maybe use for other USB devices)?
Or what are two middle pins for?
Here photo of my Poor's man dock. During photo there was no middle pins connected, but believe me , tried many options.
Edit, as I am new user , I can not paste links, but after 10 posts , I will update.
Edit 2 as I can not paste links, but if someone interested in photo , add http by yourself...

After one month of testing , I cat tell you that it is not necessary to figure out middle pins.
The device charges slowly (somewhere was written that it is limited to 0,5Ampere), but it is ok for me as during night it will be charged full anyway.
Device also activates nicely "daily board"with clock and looks nice.
I recommend this DIY stand. Made of old ethernet socket for pins, and USB printer cable.
Below link to photo how it looks like. I plan to paint it.... someday

Shame about the slow charging limited to 500mA. I've been looking at various tablets to potentially replace my 2019 Galaxy Tab A 10.1 in the car dash. Currently (no joke intended) having a fight with things to do with hub passthrough charging and the tablet taking over the role of power supplier when the car powers down....having pogo pins as an alternate charging method might present something useful as a fix, but 500mA doesn't exceed battery usage when powered up. Have you asked anybody that owns one of the docks to crack it open and see what's inside? Back when I had a Nexus 7, the four pogo pins on the dock corresponded to power and audio out via a 3.5mm jack in the dock.
One thing to keep in mind here that Samsung supports - and requires - QC3.0 for fast charge. So, you would need a source with that standard and if you want to verify (altghough the remaining time would immediately tell you) a suitable in line power trap.
