Korean Air require you to remove batteries from Dell laptops and Apple Powerbooks before bringing them into aircraft cabin.
I wonder if any more airlines will adopt this policy?
"As a precautionary measure to ensure safe air travel, Korean Air kindly requests all passengers carrying any kind of Dell laptops (including those unaffected by recall), Apple’s iBook and Powerbook models first remove batteries from the unit before bringing them to the cabin. Until further advisory is issued, these laptops cannot be carried into the cabin if batteries are not removed. "
