I recently bought a new laptop, Lenovo U310, and when I tried using the two USB 3.0 ports on the left side of the laptop, both of them don't seem to be working. I tried the USB 2.0 port on the right side of the laptop and it opens my flash drives just fine. I tried going into the BIOS with a flash drive inserted in the 2.0 port and the flash drive was identified in the boot options; however, when I tried to do the same for both of the 3.0 ports, the flash drive doesn't show up. Does this mean that the USB 3.0 ports are dead? Is there a way to check if they are truly dead. I just want to make sure before I return the laptop as I have already installed most of the programs that use for school. Is it possible that the USB ports are disabled? Is that even possible?
