Connect an external monitor and then power up the laptop.
Instruction for the restore are in your users manual but try the function key combo to cycle thru the various display options. It usually goes Internal Only > Internal+External > External Only

You will need to read the users manual again to learn which Fn key combo is for the display. On mine it's: FN+F4.
