You've done the detail work, and now it's time to go big. Grime can hide in the oddest places, like the processor's copper-colored heat sink, so make sure you explore all the laptop's nooks and crannies. Look under the ribbon cables, around the hard drive, and near the tiny circuit boards. Start at the fan, then work your way to the ducts and vents. Using the eraser-end of a pencil or tweezers, pick off any nasty deposits you come across. Now that you're inside the laptop, use a flashlight to look around for built-up dust and dirt. Again, it may be covered with dust and lint.
Remove the panel and look for the fans-they're circular and plastic, usually about the size of a quarter, with a small propeller inside. Look for a few sets of screws, underneath the laptop near the vents. Now you'll need to open up the laptop case. Don't worry if they're covered in dust and lint, we'll get to that. Fortunately, in most cases, they're near the vents that are located around the edges of your case these slats let cool air in and hot air out. But before you can clean them, you'll have to find them. Unfortunately, like all fans, the ones in your laptop will eventually end up covered in dust and dirt, and that could spell trouble.Īn occasional cleaning will keep your laptop fans spinning effectively for years. When the temperature rises above a certain level, the fans automatically come on to keep the laptop out of the red zone. In addition, all but the tiniest models have at least a single fan some bigger systems have two or even three. To mitigate this, laptop makers put in elaborate heat sinks that absorb the heat generated by the processor. Computer components-processors, graphics cards, and the like-get hot when they run.
