Dell Laptop Fan Noise When Plugged In:

There are a few things that could be causing your Dell laptop to make noise when plugged in. The most common cause is simply dust and dirt build-up on the fan blades, which can block airflow and cause the fan to work harder (and therefore, make more noise).

Other potential causes include a faulty power supply or motherboard, loose screws or hardware, or a software issue.

If you’re not comfortable opening up your laptop to clean the fan, you can try using compressed air to blow away any dust and debris. You can also try running a system diagnostic to check for any hardware or software issues.

If all else fails, you may need to contact Dell support for further assistance.

Safety Precautions

  1. Before you begin, unplug the computer and press and hold the power button for at least five seconds to ground yourself and discharge any static electricity that might damage the computer’s delicate internal components.

2. Use a plastic opening tool or your fingernail to gently pry up one corner of the service cover.

3. Lift the service cover straight up and off of the computer.

4. Remove the screws that secure the fan assembly to the bottom of the computer.

5. Gently pull the fan assembly up and out of the computer.

6. Remove any dust or debris from the fan blades and housing with a can of compressed air.

7. Replace the fan assembly and screw it back into place.

8. Replace the service cover and screw it back into place.

9. Plug the computer back in and turn it on. The fan noise should be gone.
