Consequences of Laptop Overheating
Overheating can reduce the life of your laptop. Excessive overheating can destroy sensitive electronic components.
But wait - it gets worse. In unusual but well documented cases, physical damage to very important areas of your body can result from contact with the overheated laptop computer. In a case reported in the prestigious British medical journal Lancet, a scientist suffered burns to his penis as a result of resting an overheated laptop on his lap, even though he was fully clothed. Another study reported that use of laptops in laps can cause reduced fertility in men due to the increasing of testicular temperatures.
In the normal case, however, it is your laptop or notebook that suffers shortened life from overheating. Excessive heat can damage sensitive electronic components and dramatically shorten the life of you notebook or laptop computer. Ignoring a problem with an overheating laptop invites more significant problems down the road.
Causes of Laptop Overheating
Physical Causes of Laptop Overheating
For a properly designed laptop, the most common cause of overheating is blocked air vents. When dust blocks the fans and air vents designed to cool your laptop, overheating results. (In some cases, blocked vents and poor design are related, as some designs are excessively prone to becoming clogged with dust).
Software Causes of Laptop Overheating
In other cases, laptops overheat because the software designed to protect the laptop – specifically by controlling the operation of cooling fans – does not work properly. In some cases, this is due to problems in the computer’s BIOS, and can be cured by upgrading to the most recent BIOS. In other cases, upgrading or changing the computer’s operating system can cause this software to not function.
If, for example, you have upgraded from Windows ME to Windows XP, the system software designed to operate the fans may no longer work properly. (What’s worse, the laptop manufacturer may refuse to provide support in this instance, on the grounds that you changed the operating system and so are no longer operating the system as it was designed to operate.) In other cases, replacing Windows with Linux has led to this problem if the proper Linux utilities to control laptop cooling were not installed.
Design Causes of Laptop Overheating
In a distressing number of cases, laptop overheating results from poor design by the notebook manufacturers. Some manufacturers cram desktop CPUs into laptop configurations, and do not adequately provide for releasing the heat that these desktop CPUs create. Others simply have failed to provide ventilation and cooling systems appropriate for today’s CPU and video chips, which hold many more transistors than in the past and so generate more heat.
Several class actions have been filed against laptop manufacturers due to overheating laptops, including Toshiba and Dell. Previous class actions have led to settlements under which compensation was awarded to owners of overheating laptops who ran up repair bills trying to get the problem fixed. More class actions related to overheating laptop and notebook computers are reportedly under consideration.
Best Practices To Avoid Notebook Overheating
To avoid laptop overheating, follow these best practices:
• Clean the ventilation system of your laptop weekly with compressed air.'
• Always place your laptop on a hard surface. Never place your laptop on blankets, comforters or other soft surfaces that can block fans and air vents.
• Turn off your computer before placing it into a briefcase or a backpack. If you need to not turn it off, place it into hibernation to avoid any processes that generate heat. Do not ever place an operating laptop in a confined space where heat can build up.
• Install monitoring software such as SpeedFan that allows you to watch and track the temperatures of processors, hard drives and other components.
• Adjust your power settings so that heat generating components – such as screens and hard drives – power down relatively quickly if they are not needed. This will help avoid needless heat generation and build up.
• If necessary, use a laptop cooler or a system for elevating your computer to reduce heat buildup.
• If you have overheating issues and your laptop is under warranty, report the problems so that you build a record of the problem existing while the warranty applies.
• If you are buying a new computer, look before you leap. Study the reviews and avoid models and brands with known overheating problems.
