CT may be harmful to your laptop
There have been reports of a computed tomography scan being harmful to pacemakers and other medical devices:-
And putting a laptop through CT is going to deliver a generous slug of gammas to a device that is not built anywhere near as robustly as an ICD / pacemaker. To get through the casing will require more MeV than through a person, and the flux density will be higher too.
Space based devices need to be hardened against radiation flux (although low-earth-orbit radiation doses to satellites over a unit lifetime are substantially higher than one single CT). Such protection is a whole study in itself, and requires a many-tiered response to prevent failures that can range from trivial to catastrophic. The catastrophic fails occur near power supplies or motors, where the battery charging circuits or the H-bridges to drive motors fail so that the power rail is connected to ground via a low impedance circuit. Rapid, untrammelled battery discharge is one especially unwelcome result.
I whole-heartedly approve of the TSA's unrelenting efforts to keep us safe while flying, and will joyfully** endure the most undignified and invasive examinations to assure my fellow passengers that I have not shoved a bomb up my arse ... but I really do not consider this CT exam of my laptop a good idea.

** well, joyful might be an inappropriate adverb. I am not gay enough to ever be joyful about such things. But it seems the TSA will leave no turd unturned in their search for explosive devices. I salute their zeal and diligence, and wish them the best in their fruitless cavity searches.
