Sometimes some device (IBM Think Pad or even Surface PRO 4) might get some issues with USB drivers. In that case your board is not recognized in Arduino IDE and you cannot select COM port, where the board is connected.
If that happen, please first reboot your machine. Note that reboot is not always required. However it can help in most cases. If it does not help please go to FTDI site (http://www.ftdichip.com/Drivers/VCP.htm ) and download driver as shown at the picture below:
