Airport security officers may ask travellers to turn on their electronic devices, such as laptops, to ensure the safety of everyone at the airport. This is because the battery and other mechanical components of electronic devices are often too dense for X-ray machines to penetrate. If a laptop doesn't turn on, it may arouse suspicion that it is a bomb. However, some travellers have reported that they have never been asked to turn on their devices at security. This may be because newer X-ray machines can create 3D images of bags' interiors, allowing security officers to see through dense obstructions.

To check for explosives
To ensure the safety of all passengers, airport security officers may ask travellers to turn on their laptops during security screenings. This is to check for explosives. Laptops are dense enough to block X-rays, and a knife or other dangerous items could slip through a scanner if hidden underneath a laptop. Therefore, removing a laptop from its bag helps security officers to see what else is in the bag.
In some cases, travellers may be asked to turn on their laptops to prove that they function normally and do not contain explosives. Some airports made powering up a laptop mandatory, while others only required it for travellers who were afraid to send their laptops through the X-ray machine. However, security experts argued that these procedures were a waste of time, as explosives could be hidden in a functioning computer. By the late 1990s, the practice of requiring laptops to be turned on had mostly disappeared.
It is important to note that the policies and procedures regarding laptop screening may vary from airport to airport and country to country. For example, in Canada, passengers are required to turn on their electronic devices if there is any sign of tampering, such as missing pieces, tape, or cracks. In the United States, the removal of laptops from carry-on baggage has been standard practice since 2001, but there are varying reports of travellers being asked to turn on their devices. Some travellers have reported being asked to turn on their laptops at airports without X-ray scanners, while others have never been asked to do so.
If a traveller is unable to turn on their laptop due to a lack of battery or other issues, the airport security officers may take the device to a special room to be plugged in or make other accommodations. Travellers should also be aware of their rights during security screenings, such as the right to request a private area for any searches or inspections.

To check for tampering
In some countries, airport security officers may ask passengers to turn on their electronic devices to check for tampering. This means that they are looking for any signs of missing pieces, tape, cracks, or other indicators that the device may have been altered. This practice is in place to ensure the safety of all passengers and staff at the airport, as laptops are dense enough that X-rays may not be able to detect potential threats.
While it is not a common occurrence, some travellers have reported being asked to turn on their laptops or other devices during security screening. This is more likely to occur at airports without X-ray scanners or with older scanning technology. In Canada, for example, passengers are required to turn on their electronics if there are signs of tampering. However, the enforcement of this rule may vary depending on the airport and the discretion of the security officers.
Some travellers have expressed concerns about being unable to turn on their laptops due to missing batteries or other issues. In such cases, security officers may escort the passenger to a special room to plug in the device or allow them to borrow a power outlet. However, it is important to note that most travellers report never being asked to turn on their devices, and some security experts have criticised the practice as ineffective, as explosives can be hidden in functioning computers.
To avoid raising suspicion, travellers are advised to ensure their laptops have an operating system installed, even if it is just a basic one. Additionally, travellers should be prepared to comply with security requests to turn on their devices, even if it means temporarily compromising the presentation of a gift or unboxing a new device. Overall, the requirement to turn on electronic devices during airport security screening appears to be an inconsistent and evolving practice, with varying enforcement across different airports and countries.

To see what else is in the bag
Since the end of 2001, it has been standard practice at U.S. airports to remove laptops from carry-on baggage. This is to ensure the safety of all people in the airport. Laptops are dense enough that X-rays can't see through them, which means dangerous items could be concealed. For example, a knife might slip through a scanner if it were tucked underneath a laptop.
In addition to removing laptops from carry-on baggage, some airports require travellers to turn on their laptops to prove that they function normally. This is to ensure that the laptop is not a bomb in disguise. However, security experts have argued that this procedure is a waste of time, as bombs could be hidden in functioning computers. By the late 1990s, this practice had mostly disappeared. Nevertheless, some travellers have reported being asked to turn on their laptops at airports without X-ray scanners.
In Canada, passengers are required to turn on their electronics if there is any tampering, such as missing pieces, tape, or cracks. This is to ensure that the device is not being used for any malicious purposes. However, one traveller noted that this requirement is often not enforced and depends on the airport and the type of scanners they have.
While it is uncommon to be asked to turn on electronic devices at airport security, it is always a possibility. To avoid any issues, travellers should ensure that their devices are charged and functional before arriving at the airport. Additionally, travellers should be prepared to submit their devices for further inspection if requested by airport security. It is important to comply with all security measures to ensure the safety of everyone at the airport.

To check it's a real device
Passengers may be asked to turn on their laptops at airport security to prove that they are functional devices and not disguised bombs. The density of laptop batteries and other mechanical components means they cannot be effectively screened using X-ray machines.
In the United States, Transportation Security Administration (TSA) officers conduct security screenings. While TSA officers are not typically law enforcement officers, they are authorised to search passengers and their baggage. Even if the initial screening reveals nothing suspicious, TSA officers can conduct further searches.
However, it is not a common practice for TSA officers to ask passengers to turn on their devices. Some travellers have reported being asked to turn on their devices at airports without X-ray scanners, while others have only been asked to place their devices in a separate tray for scanning. In Canada, passengers are required to turn on their electronic devices if there is any sign of tampering, such as missing pieces, tape, or cracks.
To avoid the inconvenience of removing a laptop from its packaging or bag, travellers can invest in TSA-approved laptop bags that unfold completely to lie flat on the conveyor belt. These bags have no additional pockets or metal fasteners that could obstruct the X-ray scanner's view. Nevertheless, TSA agents can still request that laptops be removed from these bags for further inspection.

To check for contraband
Passengers may be asked to turn on their electronic devices at airport security to check for contraband. This is because electronic devices can be large and dense enough to conceal contraband in an X-ray image. For example, a knife might slip through a scanner if it were tucked underneath a heavy laptop. Since the end of 2001, the removal of laptops from carry-on baggage has been standard practice at U.S. airports.
Transportation Security Administration (TSA) officers conduct security screenings at airports. Most TSA officers are not commissioned law enforcement officers, and their role is limited to conducting screenings of passengers, baggage, and cargo. TSA screeners can search passengers and their baggage at screening checkpoints, but they cannot arrest anyone. Other law enforcement officers, such as airport police, are also present at airports.
Even if the initial screening of a passenger's bags reveals nothing suspicious, TSA screeners have the authority to conduct a further search of the passenger or their bags. TSA officials may test liquids carried by passengers for explosives and may ask passengers to open containers during the screening process. TSA officers may also request additional screening if an alarm goes off, including a pat-down of a passenger's religious head covering or requesting the passenger to remove it. Passengers have the right to request that the pat-down or removal of a religious head covering be conducted by a person of their gender in a private area.
The requirement to turn on electronic devices at airport security checkpoints varies across airports. In Canada, passengers are required to turn on electronics if there is evidence of "tampering", such as missing pieces, tape, or cracks. However, some passengers have reported that they have never been asked to turn on their devices at airport security, even when travelling with laptops.
