https://www.law.cornell.edu/cfr/text/49/173.162 https://www.law.cornell.edu/cfr/text/49/173.162 (c) Manufactured articles or apparatuses, each containing not more than 100 mg (0.0035 ounce) of gallium and packaged so that the quantity of gallium per package does not exceed 1 g (0.35 ounce) are not subject to the requirements of this subchapter. For transportation by aircraft, such articles and apparatuses must be transported as cargo and may not be carried onboard an aircraft by passengers or crewmembers in carry-on baggage, checked baggage, or on their person unless specifically excepted by § 175.10. I don't know how much gallium TIM they put in these laptops but I do wonder if there is a legal risk from carrying one onboard.
