One of the most common mistakes is to leave your laptop (or other mobile gear) in a hot car. Inside a hot car exposed to the sun, you will find your laptop heating up extremely rapidly. Just like you won't leave people or animals in the hot car, you shouldn't leave your laptop in there either.

Most laptops have a safe operating temperature range. This tends to be between 50 to 95 degrees Fahrenheit or 10 to 35 degrees Celsius. Make sure you normalize the temperature of the laptop before using it indoors or outdoors. For example, if you intend to use your laptop outdoors, warm it up slightly to the outside temperature before starting it up.

Remember another thing besides heat - the humidity. Humidity is the amount of moisture in the air and usually the suitable range for laptops is 10 to 80%. If you have excessive humidity, you can have moisture forming on the laptop (or worse, its internal components). So be careful of humidity.

One of the most important tips is to store your important data in a removable hard drive. If you find your laptop operating in hot temperatures, it is always safer (and assuring) to know your data is backed up elsewhere.

This point tends to be overlooked - packing of the laptop. Try to pack your laptop intelligently, and insulate it against heat, direct sunlight and moisture. A good, solid laptop case will also make sure the machine is well-protected.

You should be careful of the weather too. Severe storms and cause your laptop to malfunction, especially if it is not surge protected. Make sure your mobile gear includes a surge protector and a spare battery. The surge protector helps to shield your laptop from electrical surges. The spare battery is a backup in case your main battery gets damaged.
 

Laptop surge protectors are important pieces of equipment

A laptop stand is increasingly more important as more and more folks turn to laptop usage. Ensure that you get a good model that can disperse heat that your laptop generates. The best ones include fans to help with the heat dissipation.
