Hello everybody, I'm happy about my ICONIA W700 I5.... untill yesterday.

I've connected an USB cable done by myself connected to a ION battery (3,7V) and it's charge circuit.

Problem is that I wrong to solder cables and I inverted positive with negative.

Battery + circuit are burned.

Now USB doesn't work. If I connect an USB dongle mass storage it's LED flash and nothing else.

I think USB controller is dead but I cannot find any electrical schematic (I should repair it)

Somebody can help finding problem on the motherbord?

 

THANKS A LOT
