Ok so my TF701 will charge just fine while connected to the wall charger, but it wont charge at all while connected to a computer. The instruction manual says it will and the general population of users agrees. However when I plug it into my computer the tablet still shows as discharging.

Yes the USB ports work fine. Tried in 4 different computers, nothing.

Anyone have any idea what is wrong?

Tab actually requires 12 to 15v to charge - hence the proprietary charger and connector . A usb port only provides 5V.

It will actually trickle charge over USB but it is extremely sloooooooooooooooooooooooooooow. If you use the tab whilst connected to USB it will discharge faster than it can charge.

The stock charger is actually only 5v, it's a USB standard. However the charger produces something like 40watts as opposed to standard USB chargers of 10-20watts.
