For most things, no. But the key combination to switch to the external
monitor requires that special Fn key, which is present only on the internal

Closing the lid may cause other problems. Many laptops are set up to
enter suspend or hibernate mode when the lid is closed, unless they are
currently installed in a docking station. Apparently yours isn't,
but this operating state is one that I'm not familiar with.

Maybe it doesn't work on yours because you're not doing it the way
I suggest. You insist on closing the lid and using an external keyboard.
The key combination to switch to the external monitor may not be
Fn+F7 on your laptop. Maybe it's Fn+F2. Consult your hardware documentation.
But there should be a way. xrandr is an X-specific tool. I know of no equivalent
tool for the console. Once you switch to the external monitor with
Fn+F2, or whatever, and have verified that both text mode consoles and
the graphical console are using the external monitor, then try using
the external keyboard. If everything is still working, then try closing
If this procedure doesn't work, then I'm out of ideas. You're on your own.
