USB Connection When I plug in my I Phone to the computer it does not recognize it. It doesn't do anything. I have a wall charger and that works, so its not the output. I checked the cord with another I phone and that works properly. My I-tunes is a 7.6. Please help with any answers. Thanks

Some tablet brands will not recognize certain charger brands or connections.
First, try all available connections-USB-wall inverter, and direct computer connection (making sure the computer is awake and logged in). Second, try restarting your tablet. Third, try gently wiggling the connections on both ends, to see if it recognizes a charge. Finally, leave it plugged in for a few hours, even if it says it isn't charging. You may have a trickle charge-to put it simply, the cord is not giving the device enough power to qualify as a charge, but there is power traveling through the cord. If the charge level goes up a little over that time span, you have a trickle.
If these don't work, just purchase a new charger. They're sold everywhere-Wal-Mart, Target, Best Buy, 7-Eleven, name a store and they probably sell USB charger cords.
I hope I helped.

The problem very well could be that it isn't connected fully (maybe not fully plugged in). or that the USB port on your laptop is dysfunctional. The charger could even be malfunctioned. Try to charge in another USB (as not all are powerful enough to do so). If that doesn't work, you could buy a new usb cord to try that, and then if that doesn't work you may just want to stick to using the wall charger.

I have the same problem with my iPhone. The only real way and best way to get a charge on a phone is through a wall charger. Car chargers and computer/usb to charge doesn't actually do anything but "top off" the battery. They don't produce enough power to give the batter a strong charge like the wall can.
That's my best advice. Charge from the wall when at home. Use the car to top off when your on the go.

HiIn order to check quick, you might need extra battery. In your neighbor some who has multimeter you get help from them. Or your local repair shop could help you easily.

My Sony Walkman NWZ-E344 not show anything to display.
Display show only logo & i have connect pc then show "connected USB.the timer and Alarm will become invalid"
pls solve this problem?

It could be the charger, the phone's power interface, or your battery. When you plug the phone in to charge it, does it recognize the charger and show the lightning bolt symbol for charging?

If you use your computer's USB port to charge it instead of the wall charger, does it act any differently?

If it uses a separate connection for the charger, try cleaning the contacts (a toothbrush works well for this) on the phone and the charger plug. If the charger plugs into the USB port on the phone, I's suspect a bad charger.

If your iPhone is not charging when you plug it into a wall charger or into you computer's usb port, this is a usb connectivity issue and the connection just needs to be reset. All that needs to be done is plug the iPhone's cable into the phone but don't plug into the computer yet. Hold the phone's select button (the round button with the square) down for about 30 seconds or until the apple appears on the screen. your phone will reload and reset the connection and the computer should recognize the device. Allow the phone to charge for at least 30 minutes before unplugging.

you can use just the usb cord connect it to your computer to charge the adapter for the wall mount is were your problem is occuring. I had the same issue.

you have to get another usb connecter not the wall charger cable
