Hi:
Did you reinstall the operating system?
The ports on the left side are USB 3 ports and they need a driver.
The problem is, you notebook can have one of 3 different model usb 3 controllers so I don't know what driver it needs.
Go to the device manager and if a driver is needed, there should be an Other Devices category and there should be a USB controller listed there with a little ! mark next to it.
If there is, click on that and do the following...
Then click on the Details tab at the top of the USB Controller window.
Now you see a Property drop down list and it is defaulted to Device Description.
Drop down on that and select the second item on the list (Hardware ID's).
Post the top string of characters that begin with PCI\VEN.
