This is the typical way to use screen:

- Turn on your laptop, open ssh connection to the server
- On the server: type 'screen'
- screen will give you a shell, just like when you log in normally
- Do work that you need inside that shell
- If you get disconnected, such as when you turn off your laptop, screen 
will still be running on the server
- When you want to reconnect, turn on your laptop, and connect through 
ssh to the server again
- type 'screen -D -R' to resume screen where it was before you turned 
off your laptop.

It is not possible to resume the exact SSH connection when you turn off 
your laptop because networking doesn't work that way.  Instead, you must 
create a new SSH connection and then use screen to resume what you were 
doing inside the screen session.
