ACER ASPIRE 315-51 and my USB 3.0 failure. Need to fix the USB since external backup disk uses it

FrankHeuvelman

I own a ACER ASPIRE 315-51 and my USB 3.0 port had a shortcut caused by a faulty wire.
When I switched on my laptop I got a message that this port was consuming too much current and was subsequentially switched off.
Because I now know what caused this shortcut I want to turn this port on again because my external backup disk uses this port so I can no longer read or write to this disk.

I measured the voltage on the +5V pin and it has a voltage of 0.53 Volts.

The data lines seem to be active.

Can I turn this 3.0 USB port on again and how do I do this?

Thank you.

Hi Frank,

Get that USB short circuit fixed at Acer Services in your country (Holland?), you may get major motherboard issues if you continue to use it. 😉
