How do I get a monitor plugged in to the laptop to work when the laptop monitor is broken? Have tried changing from BIOS but video options and not available. Help!

There is a key combination like Fn + F3, Fn + F5, Fn + F8, or Fn + F9 used to switch between the laptop and the external monitor, you will need to consult your owner's manual or go to their wed site to get this information. If you can't find it post back here with the make and model of your laptop and we will see if we can help find it.
