Well, what does it do? The most useless problem report is "it isn't 
working". That tells us nothing.

Does it raise an exception? Crash? Set the laptop on fire? Something 
else?

Quite possibly. Can he send email from his laptop? If so, how? Does he 
use Gmail via their website, Outlook, something else?

Does his ISP block outgoing email on port 25? Many ISPs do, to try to 
prevent viruses from sending out spam.

Does your friend actually have a mail server running?

I recommend that you run through the example here:

https://docs.python.org/2/library/email-examples.html

and see what happens.
