Question Lenovo Yoga 2 USB Not working

[nemanja29]

Hi, I made a short circuit on Yoga 2 13", after that laptop same sec shut down when I powered it up, everything is fine except both USBs... I tried removing the battery, putting BIOS on default, on device manager it says everything is okay, Lenovo diagnostics says USB is ok, is there something I can do or USBs are just dead?

Sounds like the USB ports are fried.

You can try to reset the motherboard fully, remove the battery and wall power, remove the CMOS battery if there is one, hold in power button for about 30 seconds. Plug in wall power only and see if the ports work after that.
