In this case, you can disable the uncommon devices such as the PCMCIA card, modem, infrared device, printer port (LPT1), or serial port (COM1) in the Device Manager, double-click the device you want to disable. In the Properties dialog box, select "do not use this device (disable)" on the "General"
