X-ray the laptop at the airport? Happened what?
Nope, what should happen? You do not come around and besides it is made thousands of times every day without any problems.
Laptops are classic hand luggage, which is always x-rayed
Röngten should have no influence on the device at all. Not asking for roaches will only cause you trouble, after all you could fill in enough space to blow up a plane even if the device is working properly.
It can of course occur in such a device in relation strong magnetic fields, but even these should not hurt a notebook, otherwise everyone would fall over with pacemaker if he passes it. Furthermore, you also leave your purse / clock, etc. Through the machine, and your whole magnetic cards work after that…
No. If it did, we would have destroyed tens of thousands of laptops, tablets, phones, and so on. Our x-rays, which produce our equipment, are too small to cause any damage whatsoever.
