If the battery is the issue, disallow bringing the batteries.

Make them replaceable, and you only need to buy new batteries at the destination.

Create a standard around batteries (like palettes) and you may only need to borrow them.

This standard doesn't yet exist. This makes the ban (as a sudden thing) a non-starter. It also creates a massive burden on the economy to start acquiring such laptops. OTOH, it'd be a major boon to device manufacturers. Perhaps this is economic stimulus masquerading as security theater.
