12v supply has blown my usb ports

hancor2 — Thu, 18 Jul 2013 10:11:20 GMT

I have an Acer 5738z and I stupidly plugged a 12v supply from the back of a monitor into one of my laptop's usb ports. I now have zero working usb.

Can anyone point me in the right direction for what might have blown, fried or just died?

I am guessing it will be a shop fix job, but it might be something silly like an overload shut off. I have tried a factory restore but that failed.

Thanks

USB ports would be mainboard

Thanks for reply.... Have managed to sort my issue by other means.

I wanted to get back the abilty to connect a mouse to the laptop and with blown USB was facing an unbreakable wall, so me being me and having this strange love of fiddling I stripped a USB cable from it's male end (leaving the female intact) and using a plug similar to an internal bluetooth modem I took the tiny metal connectors our and carefully wrapped them in tape and slid them onto the pins for the socket I would have plugged a BT Module into, then removing a BT USB Dongle from it's case I wrapped it in tape to isolate it and plugged it in........ Success - I now have internal BT with a BT mouse and I'm happy again.

I did have to source a schematic for the mainboard so I could work out the correct wiring order but got lucky first guess, and I had to remove some plastic parts from the inside of the palm rest so it would all fit with the laptop intact.

Hancor, you need to be writing FOR us, not TO us.
