I tried using my USB HUB with an Power supply, but I didn't noticed the power supply was 12V. After connecting the USB HUB my Laptop shutdown, It started back again normally but now the 2 USB 2.0 ports don't work anymore. Link
Did I fried the USB ports? Is it hard to replace? They seem to be separated from the rest of the Motherboard but are together with the Headphone and Laptop AC Adapter connectors (which are fine btw)
