How to Clean the Fan on a Laptop

Clean the fan on your laptop by spraying the cooling vents with a can of compressed air. You can also take the bottom vent panel off of your laptop and access the fan directly. Either method will help prevent overheating, which can cause a slow laptop or a quick death of it entirely.

Cleaning the Vents With Compressed Air

Step

Place your laptop on a clean surface that you don't mind getting dirty.

Step

Locate all air vents on the bottom of the laptop. There are side vents, back vents, and vents on the bottom of the laptop. Cooling vents are identified by the copper or black fins inside the vents.

Step

Angle the can of compressed air into all of the vents and spray the vents with short bursts of air.

Taking the Bottom Panel Off to Clean the Fan

Step

Place your laptop on a clean surface that you don't mind getting dirty.

Step

Turn your computer off and disconnect the power cord. Turn your laptop over and remove the battery.

Step

Locate the removable panel on the under side of the laptop. Remove all of the screws that hold the panel in place. The panel is now easily removed.

Step

After the vent panel is removed, you can access the cooling fan. Using the can of compressed air, blow the dust off the fan with short bursts of air.

Step

Replace the panel back on to the laptop and tighten the screws. After the panel is reassembled, attach the battery and power up your laptop.
