Laptops and airport scanners
Airport security checks can be stressful, especially when you have valuable items such as laptops in your possession. It is natural to be concerned about potential damage to your laptop when passing through airport scanners. Here is some information on what to expect and some tips to help you navigate the process.
X-Ray Scanners and Laptops
X-ray scanners are commonly used at airport security checkpoints to inspect carry-on luggage and electronic devices such as laptops. While some people have expressed concerns about potential damage to their laptops from X-ray scanners, it is important to understand the technology involved and take appropriate precautions.
X-rays are a type of electromagnetic radiation with a shorter wavelength and higher frequency than visible light. They can pass through objects like plastic, skin, and tissue but not bones or metal. X-ray scanners at airports use a specific wavelength of light, and the intensity of the X-rays is too low to cause damage to laptops or other electronic devices. Laptops do not contain any photosensitive materials that would be affected by X-rays.
However, it is recommended to remove laptops from bags before placing them in the X-ray machine. This is because the dense components of laptops, such as batteries and power cords, can interfere with the X-ray image, making it difficult for security personnel to identify potential risks. By removing the laptop, security officials can obtain a clear image of its internal components.
Metal Detectors and Laptops
While X-ray scanners are generally considered safe for laptops, metal detectors may pose a risk. Metal detectors emit strong magnetic pulses that can potentially erase hard drives. If possible, request that security personnel perform a hand-check or use an X-ray machine instead of a metal detector for your laptop.
Tips for Travelling with a Laptop
- Backup your computer and set a login password for data protection.
- Fully charge your laptop's battery to ensure it can be turned on during security checks.
- Purchase a power converter suitable for the country you are visiting.
- Pack your laptop in a padded bag designed for laptops to protect it from potential impact damage during transit.
- Keep your laptop with you at all times and easily accessible for security inspections.
- If your laptop is stolen or damaged, notify airport security and the police, and file a claim with the appropriate authorities, such as the TSA Claims Management Office.

Metal detectors and laptops
When travelling with a laptop, it is recommended to send it through the x-ray machine instead of a metal detector. Although x-rays are a form of electromagnetic radiation, they are not radioactive and do not leave any lingering residue. The Earth is constantly exposed to radiation, most of which comes from the sun, and the radiation from airport x-ray scanners is much lower than the radiation your laptop will be exposed to in-flight.
X-rays are used to create images of the contents of your bag by measuring the amount of x-ray that passes through an object to calculate its density. Laptops and other electronics block x-rays, so they show up as dark objects on the image. While x-rays can theoretically affect flash storage by erasing some cells, the intensity of the x-rays used in airport scanners is too low for this to happen. Laptops also do not contain any photosensitive materials, so they will not be damaged by x-rays.
Metal detectors, on the other hand, send out a strong magnetic pulse that can erase hard drives. If you are concerned about potential damage, you can request that security perform a hand-check of your laptop instead of sending it through the metal detector.

Laptops and travel
Travelling with a laptop can be stressful, especially when it comes to airport security. Here are some tips to make the process smoother and safer for your device.
Before Your Trip
It is recommended to fully charge your laptop before your trip to ensure it has enough battery life for airport security checkpoints. Additionally, set a login password to protect your data, and back up your computer, storing the backups safely. For international travel, purchase the appropriate power converter for your laptop, and consider calling your destination hotel to check for internet access.
Packing Your Laptop
It is advisable to pack your laptop in a padded bag specifically designed for carrying laptops. Do not check your laptop in with your hold baggage, as it may not be handled with care. Keep your laptop with you at all times and ensure it is easily accessible for security inspections.
Airport Security
Most airports will require you to remove your laptop from your bag when passing through security. This is because the battery and other mechanical components are too dense for X-rays to penetrate effectively, especially with older scanning systems. By removing the laptop, security officials can get a clear scanned image of the device and its internal components.
While X-ray scanners are generally considered safe for laptops, some travellers have reported issues with their laptops after passing through airport security. These issues include fried hard drives, damaged internal WiFi sensors, and screen problems. To minimise potential damage, you can request a hand check of your laptop instead of passing it through the X-ray machine or metal detector. Metal detectors, in particular, can send out strong magnetic pulses that may erase hard drives.
In-Flight and At Your Destination
During your flight, follow the crew's instructions regarding the use of electronic devices. Usually, you will be asked to stow your laptop away during take-off and landing and adjust your power settings to conserve battery life. When you reach your destination, be cautious about where you store your laptop. Do not leave it in the overhead bin, as other luggage may be placed on top of it. Instead, keep it in a safe place, such as a hotel safe, and avoid taking it to places with excessive sand or moisture.

Airport security checks are a necessary inconvenience that can be stressful, especially when you have valuable items such as laptops. It is important to know how to navigate these checks to ensure the safety of your devices.
X-rays and Laptops
X-rays are a type of electromagnetic radiation, similar to visible light but with a shorter wavelength and a higher frequency. They are not radioactive and do not leave any lingering residue. Airport X-ray machines use a specific wavelength of light to create images of your luggage, which helps security personnel identify potential threats.
Laptops are dense with materials, and their batteries and mechanical components can be too dense for X-rays to effectively penetrate, especially with older scanning systems. This is why laptops are often removed from bags at security. However, this does not mean that X-rays will damage your laptop. While theoretically, X-rays can affect flash storage and cause data loss, the intensity of X-rays used in airport scanners is too low for this to occur. Laptops also do not contain any photosensitive materials that could be affected by X-rays.
Metal Detectors and Laptops
While X-rays are generally safe for laptops, metal detectors may cause issues. These detectors emit strong magnetic pulses that can potentially erase hard drives. If possible, request that security performs a hand check of your laptop instead.

Airport security and laptops
Airport security and procedures have changed dramatically since the terrorist attacks in the US on September 11, 2001. One of the most common requests (or demands) made by airport security staff is for passengers to remove their laptops from their bags. This is because laptops are dense with materials, and their batteries and mechanical components are too dense for X-rays to penetrate effectively, especially with older scanning systems.
Laptops are required to be screened separately from their bags so that their internal components can be viewed on the scanner. This is done to ensure that the laptop itself is not being used to conceal dangerous items.
While it is generally agreed that X-ray scanners are safe for laptops, some travellers have reported issues with their laptops after passing through airport security. These issues include damaged hard drives, poor Wi-Fi reception, and screens failing to display properly. However, it is unclear whether these issues were caused by the X-ray scanners or other factors, such as physical handling during security checks or variations in voltage when charging the device in a different country.
To minimise the risk of damage to your laptop when passing through airport security, it is recommended to keep it in a padded bag designed for laptops, separate from your other carry-on luggage. This will make it easier for security staff to screen the device and reduce the risk of accidental damage. Additionally, it is advisable to back up your laptop data before travelling and store the backups separately from your device. Fully charging your laptop before travelling will also ensure that you have enough battery life to turn on the device at the airport security checkpoint.
It is worth noting that while X-ray scanners are considered safe for laptops, metal detectors and wands may potentially damage your laptop's hard drive. These devices emit strong magnetic pulses that can erase data. Therefore, it is recommended to request a hand-check of your laptop instead of passing it through a metal detector.
