Sony Experia T - USB wont charge

[Android Question]

I can't get my pc or laptop to charge my phone. But when i plug the same charger into a socket it charges fine.
On previous phones a 'new software found' appeared on my pc and allowed me to charge, but nothing happens with this phone.
I have checked and the 'usb connection mode' is in MTP.
Can you help?

Are you using the same cable with the charger and the computer?

It sounds as if you're using a "power-only" cable. Some USB cables have 2 wires - power. Some have 4 wires - power and data. A 2 wire cable won't do anything but charge th phone. (If th phone didn't come with a separate cable - not one permanently fastened to the charger - you'll have to buy a 4 wire cable.

You also have to install the Sony USB drivers in the computer and laptop, but I assume you've already done that.
