It doesn't. Check the usb socket for dirt and the existence of clean contacts.

[Q] Sensation charging cable.

Hi guys, usb cable that came with my device doesn't fit probably with my case on. Would I get the same voltage output if i use a different usb cable with the stock charger?

Yes it's just a USB cable.

Charging Cables

Do the TF200/Prime/Other cables word with the Infinity?
I'm thinking about just getting a couple of spare cables here: http://www.amazon.com/gp/product/B007GJR7GS/ref=ox_sc_act_title_1?ie=UTF8&smid=A1HKVQTYI2W24Y but want to make sure that they fit and work.
Also, (perhaps a separate thread?) Can we use any AC to USB converter (and cable) to charge the Infinity? The adapter bundled with mine was a bit more robust than normal adapters so I'm inclined to think no, but wanted to confirm before I get a spare one.
My cable from my prime works with the infinity....I also tried a cigarette to USB plug in my Jeep and it would not charge the Infinity
if anyone finds out if other USB charging adapters work successfully, could you please post about it?
much thanks

None of them will work. The charging cable for the TF700 doesn't use any the USB pins for charging. It has additional USB3-style pins hidden up inside the connector. Also, the stock charger outputs 15V which I doubt we'd find on any standard USB charger.

Actually, correcting my previous post, it can charge via a USB 2.0 connection (as on a standard USB charger) but very very slowly. The current is not enough to charge it while the screen is on. The display will read, "Not Charging" but it actually does. See the following thread for more info:

I want to extend the charging cable. Can I use any regular USB M to F cable or do I need something specific?

you need a usb 3.0 extension cord to extend the cable

Umm... did you actually test that? I went through my charger pin by pin with a multi-meter and found 5 VDC between pins 1 and 4. Look closely at the charger, it says it can supply 5VDC @ 2A or 15VDC @ 1.2 A. The only reason for switching to 15VDC would be if they had some sort of feedback signal on pins 2 and 3 going to the plug-in adapter to signal that the battery was fully charged and tell it to switch to a higher voltage/lower current mode.
ASUS standard charging cable has 5 pins instead of 4. I'm betting the feedback you're looking for actually occurs on the 5th pin.

i am using the original charger to the wall charge. even i plug it into pc the red cross still showing. any solution?
As it's stated above - The Galaxy Note 10.1 can not charge threw USB due to the high power usage, all it can do is a "status quo" on battery usage.
So if you wan't to charge the Note, plugg it directly into the wall, and if possible, avoid power extenders.

If you are using the ac charger and the original cable, then you may have a fault in either the charger or the usb cable
If you can borrow a friends usb cable test to see if that helps
If not try your friends charger.
After a while the usb cable gets damaged and when damage can show a fault in different ways
Slow charging
The red cross appears
It shows charging but the battery never goes pass say about 1%
It shows charging but instead the unit is discharging.
If you get any of these before you wipe your device try another cable if possible
I have had my replaced already and ferl I will go and get a docking unit, and a spare cable

sorry for late reply.
i did get a new charger from ebay but unfortuately the red cross is still there but nevertheless it charge slowly.. it took me about 8 to 10 hr for fully charged.
any other solution?
The probabilities are:
Charging Port is broken
Charging cable / Charging cable connector(s) is(are) broken
AC Charger is broken
Analysis:
Borrow someone else's charger & cable
Try the combination :
Other charger + your cable ==> if working then your Charger is broken
Your charger + other cable ==> if working then your Cable is broken
Other Charger + other Cable ==> if working Both Charger & Cable are broken
If all failed ==> your Charging port are broken

[Q] USB Charging port fix by crimping USB Cable?

Hello,
I was having problems with my S3 not charging when plugged into the USB charging cable. If I would wiggle the cable around, it would start charging. Then if I set the phone down, it would stop charging. I figured the USB port was loose and/or broken. However, I took an old USB charging cable and I crimped the end down to "tighten" up the small opening in the end of the USB cable. Now it charges, the USB connection to the phone is very tight and it starts charging and stays charging. Problem solved?
My question is why do I need to crimp the USB cable? Has my USB port on the phone worn out? I've taken out the motherboard and cleaned the USB port with contact cleaner (which did not help). Does the little "prong" inside the USB port wear out?
I have recently had trouble with my phone charging from non-Samsung cables (the one that came with my phone still gives me no trouble). Similar issue, I suspect my phone port is wearing out.
Luckily, I have a wireless charger and battery cover so I dont use the port much now. Only down side is that there are no cases that fit with the VZW wireless charging battery cover.

Galaxy Tab S8 plug in to charger

Hello all, I had a question about my galaxy tab s8.
I had the charging cable plugged in to the tablet and then plugged the charging plug into the outlet and a tiny spark happened and then my tablet started showing the usb notification over again for a few times. It was not plugged into usb just into the wall socket. Is there any cause for concern or should the tablet be just fine? It seems to charge fine and I dont notice anything different. Any response is much appreciated. Thanks.

I think that you have nothing to worry. May be the charger plug didn't have proper seating in the socket which resulted in the on and off connection. This may have triggered the notifications. In future, please ensure that the pin seats tightly and correctly in the socket.
