Considerations
Passengers are often asked to remove laptops from laptop bags before sending them through the scanner. In late 2008, the Transportation Security Administration revised its laptop rules; its "Checkpoint Friendly" specifications designate TSA-compliant bag styles that can be sent through the scanner with the laptop inside.
Laptop Bag
A laptop bag must contain a section specifically designated for the laptop, which can be unfolded or opened to lay flat on the scanning belt. If your laptop has a simple protective sleeve (no pockets and no zippers) around it, you may leave that on the laptop as it goes through the scanner; however, you must remove the sleeve-covered laptop from your briefcase or bag.
Obstructions
To avoid issues during the screening process, make sure that there are no snaps, zippers or buckles near the laptop, or any other obstructions above or below the laptop when placed flat on the screening belt.
Packing
When packing your laptop, do not leave power cords, chargers, network cables or other accessories loose in the laptop bag, as these may cause a delay in security screening. Neat and organized bags will speed the process.
Warning
Although no longer a common practice, you may be required to turn on your laptop computer during security screening and demonstrate that it is operational. Be sure that you have the laptop fully charged or have easy access to the power cord to avoid security delays.
Misconceptions
According to the Transportation Security Administration website, you should not pack your laptop in checked luggage, as this may cause the baggage to be delayed for additional screening.
