How to Troubleshoot an Overheating Laptop CPU

Laptops contain a central processor with a fan dedicated to cooling the processor

. Unlike desktops, space requirements limit the size and power of laptop fans, as well as the amount of ventilation. This can cause a laptop to become clogged with dust, trapping heat and overheating the CPU. If you think your laptop's CPU is overheating, there are several steps you can take to attack the problem.

Feel the bottom of the laptop and sides to see if it is warm or hot to the touch. Most CPU's can operate safely up to 65 or 70 degrees Celsius, but may overheat above that. If your laptop feels hot to the touch, there's a chance the CPU is running too hot. If it is just mildly warm, your CPU is probably fine. HP pavillion battery

Use a CPU temperature monitor to determine the exact temperature. Motherboards are installed with a CPU monitor which can be accessed during start up by entering the BIOS setup utility. (This usually requires pressing a certain key, such as delete, F1 or F2 during start up.) While checking the CPU temperature during start up can be useful, it is even better to monitor the CPU temperature during use, when it is more likely to overheat. There are several free downloads that tap into the motherboard's temperature monitor system and allow you to view the CPU temperature in real time. Speedfan and Everest are two popular temperature monitors (see Resources). If the CPU temperature is over 70 degrees Celsius, you should take steps to cool it down.

Use a screwdriver and can of compressed air to clean the dust inside your laptop. Depending on your laptop model, the panels and screws you will have to take out to access the interior will vary. Consult your laptop's manual or manufacturer's website for assistance accessing the CPU and fan. Use a can of compressed air to lightly blow away any dust inside.

Use your laptop in a cooler environment. If you use your laptop in a warm, stuffy room, or in direct sunlight, move to a cooler area. Make sure the laptop's vent (where the fan is blowing) is not covered up. IBM laptop battery

Do not overtax the computer's processor. Running multiple programs at once, and complex graphic editors or games stresses CPUs. If you often multitask or play games, consider reducing graphics settings or running fewer programs at once.

Purchase a laptop cooling station to keep temperatures on the bottom of your computer down.
