Do you ever have any trouble at airports? The one time I ever had grief at an airport was a few years ago travelling with an X230 with the larger battery pack. Security seemed extremely suspicious of such an old laptop and I got stopped again later by a plain clothes security guy.

I've never had any problems! I'm surprised airport security would be so concerned about an old laptop. I'm sure they see way strange things on a daily basis.

Identical setup here, and yes, checkpoint security at an airport in Germany pulled me to the side and made me turn it on to show it was a functioning laptop
