    You must remove one DVD drive screw and pull drive out. The remove 17 bottom cover screws to remove cover. Then reseat ribbon cable to the  mainboard to help clean the contacts to the two usb ports. Some models may have ports soldered to mainboard in which case they may be loose.

    How do I run diagnostics?

    There are no software diagnostics for intermittent usb problems like this.

    One of the biggest problems with these ports is that they easily collect lint, hair & food debris over time  that can impede proper contact.

    I suggest that you peer inside the ports with a flashlight to see if there are any visible dust bunnies or debris. Use a toothpick to try to dig it out.

    If none, you can try to help clean the contacts of dirt or corrosion, Moisten a flattened Q-tip with rubbing alcohol. Gently rub the gold colored contacts embedded in the blue or black plastic
