Laptops, once known as the accessory of the traveling business person, are becoming as popular as desktop PCs. For many, a computer one can take anywhere is more appealing than one anchored to an office desk.

A downside to that portability is an increase in the risk of theft and damage. Every time you travel with a laptop - be it on a flight or a trip to the store - you're at risk of losing or harming a product that worth hundreds, if not thousands of dollars. Here are some tips to help protect your computer when traveling.

Find a good computer bag

Protection is the number one factor here. A padded interior pocket for the laptop is essential and is what separates computer bags from other bags. Protection from the elements is also important. Vinyl bags provide decent water protection, but are not completely "water-proof." If you need superior water protection, try a company like Ortlieb (http://www.ortlieb.com/) that specializes in waterproof bags.

Airport security

Laptops must be removed from their bags and placed in a bin when passing through security checkpoints at US airports. Be prepared so you don't have to hurriedly remove the computer and place it in a bin. A thinly-padded sleeve will provide some protection in such instances when your laptop must be removed from its bag.

Battery life

If you're like most laptop users, you wish your battery had a longer life. To help keep the life of your battery, allow it to fully drain once you use it. Don't charge half-juiced batteries. Also, adjust your settings. Decrease the amount of time it takes for your laptop to go into "sleep" mode. Lowering the screen brightness will also save energy, as will closing unused programs and functions (especially the wireless card, which continuously looks for a signal when on).
