Enabling or disabling the USB in BIOS setup program

1. Turn on or restart your computer.
2. Press F2 when the Dell logo is displayed on the screen to enter the BIOS setup program.
   NOTE The F2 prompt indicates that the keyboard is initialized. This prompt can appear very quickly, so you must watch for it, and then press F2. If you press F2 before the F2 prompt, this keystroke is lost. If you wait too long and the operating system logo appears, continue to wait until you see the desktop. Then, turn off your computer and try again.
   The BIOS setup program is displayed.
3. On the left pane, select Settings > System Configuration > USB Configuration.
   The USB configuration is displayed on the right pane.
4. Select or clear the Enable External USB Port check box to enable or disable it respectively.
5. Save the BIOS setup program settings and exit.
