Why do I have to take my laptop out of my bag during security screening?

"The reason you need to remove laptops and tablets from your backpack first is because of the batteries," explains Michael Sørensen, who works in the screening department and often sits in front of the security scanner. "Also, these devices are often made of thick, dense metal, making it difficult for the scanner to see what's underneath, hidden by the computer in the bag. If I notice a computer in a bag, I ask the passenger to take it out, put it next to it, and scan the entire thing again."

These items hidden by the laptop may be prohibited items in carry-on luggage, affecting flight safety.

Computer batteries have always been a headache for the aviation industry because of their danger and the risk of explosion. The US Federal Aviation Administration warns that if an overheating computer battery is placed in a bag, next to flammable items such as deodorant spray, a fire can quickly break out. The fire can spread quickly and engulf the entire plane in smoke.

Also related to electronic devices, passengers when passing through airports in the UK should be careful not to let their phones run out of battery and not be able to turn them on at the security screening gate when requested. If this happens, your items may be confiscated. This information is widely published on the UK Government website.

The website only gives a warning and no further information, but aviation experts say the reason is related to flight safety. It's best for travelers to follow the rules to avoid trouble. "Make sure your phone is fully charged when you get to the airport," says travel expert Sammy Vagabond.
