(Editor's note; This is from our friends at Hewlett Packard, but these tips will work with virtually any notebook device. Safe travels!)
As a frequent traveler, your notebook must be able to withstand the stresses of mobility. Bumps and bruises, minor spills and high reliance on battery power are all conditions that you’ll want your notebook to handle with ease. But it’s not all up to your notebook—there are a couple techniques, some helpful products and some buying advice that’ll help make your business travel more stress-free.
1. Stress-free screening: Make going through the x-ray machine less stressful by choosing a carrying case that enables airport officials to scan your notebook without you having to remove it from the bag. The HP Evolution Checkpoint Friendly Case zips down the middle to allow clear x-ray scanning by isolating the notebook to one side. Designed to accommodate notebooks with up to a 16-inch screen, the case also features the SafePort Air Cushion System for notebook protection.
2. Batteries with more life: You can stretch your notebook’s battery on the flight by reducing the brightness of the screen. When the aircraft lights are dim, turn down the screen brightness to as low as feels comfortable. Check out the HP customer care guide "Improving Battery Performance" for more tips on maximizing the power capacity of your HP notebook.
3. Power when you need it: If you’re a power user, don’t substitute functionality for low weight. You’ll save a lot of frustration if you choose a notebook that’s designed to handle your workload. For instance, if you work with graphics-intense applications that require processing power, a notebook geared only for mobility won't meet your needs.
The HP Elitebook 8570w Mobile Workstation, aimed at photographers and power-users, for example, has a 15.6-inch diagonal display and supports up to 32 GB of memory.  (System memory stores actively running software on the computer.) The HP Elitebook 8770w Mobile Workstation, aimed at digital-content creators, features a 17.3-inch display and supports up to 32 GB of memory. 
Because of the bigger screen size and other components, the weight of the EliteBook Mobile Workstations starts at 4.96 lbs. This compares to the HP EliteBook Folio at 3.56 lbs, designed for typical business usage. 
Weight vs. power is a trade-off that road-warrior notebook buyers need to consider.
4. Power up: Before you fly, find out if the plane has a power outlet in your seat. This will help you decide what notebook accessory to take with you. Check with your carrier to see if your seat has an outlet.
The HP 90W Smart AC/Auto/Air Combo Adapter powers your notebook and charges the internal battery simultaneously. It attaches to an electrical outlet, auto or aircraft power charger, depending on the model.
5. Keep nosy seatmates at bay: In close cabin quarters, you can prevent people from seeing what's on your screen with the HP Privacy Filter. This reduces the viewing angle of notebook displays, so people on either side of the notebook see just a black screen.
 Maximum memory capacities assume Windows 64-bit operating systems or Linux. With Windows 32-bit operating systems, memory above 3 GB may not all be available due to system resource requirements.
 Four SODIMMS for a total of 32 GB of memory is available on quad-core systems only.
 Weight will vary by configuration.
