activate the screen.

Fnand F1 simultaneo usly. If you have registered a password, press
any key, type the password and press Enter. If no password is
registered, press any key. The screen reactivates and allows you to
continue working.

not set for an external monitor. To do this, press Fn and F5

and F5 simultaneously again to return the display priority to its
previous setting.

advance you through the display options.
