Hi,

 

Is your notebook still in warranty?  Warranty status check webpage

 

If some ports work and others do not, then it is quite likely that the issue is hardware related. Replacing the system board would be required to resolve the issue. If the issue were operating system or driver related, then no usb ports would work.

 

 

As a workaround you can use a powered external usb hub.  If you use an unpowered hub then you are quite likely to kill another port. You must have used a usb device that drew more current (in µA).  The same thing happens to motherboards in PCs, so don't feel lonely.  You can see what I mean about the power limits of usb ports in the following image. Go into the device manager and check your usb ports power availability and power required.

 

 

Best regards,

erico

Take it back to the dealer and ask for a replacement. If one of the ports works, then the driver is  already installed.

 

There is a systemboard hardware fault.
