User Supplied Computer

Do not turn on your laptop until the Step 3 cable connections are complete as described below.

A VGA cable with audio line is provided for connecting the user supplied laptop to the VGA jack in the wall. In many rooms, this cable is permanently attached on the cabinet end.

Laptop users may need to provide a cable adapter specific to their model laptop.

  4. If the laptop was started prematurely or it is not displaying on the projection screen, restart the laptop. Call the IT Help Desk at x4-HELP (x4-4357) for assistance if the restart does not correct the issue.
