Boot and login (it helps if the laptop was set to autologin). Then press winkey+p, one time the arrow right and press enter.
If no luck, turn it off and repeat with two times the arrow key.
If still no luck, turn it off and repeat with three times the arrow key.
My laptop screen is broken and I have tried to display on an TV using the HDMI port. Since I can not see anything, I do not know what to do. I have used fn+F5, Windows+k and other key combinations without success.
