How to replace fan in hp laptop - step-by-step guide

If you own a Hewlett Packard laptop and notice that the fan is not working properly or making unusual noises, it may be time to replace it. The fan plays a crucial role in keeping your laptop cool and preventing overheating, so it's important to address any fan issues as soon as possible. In this guide, we will walk you through the process of replacing the fan in your Hewlett Packard laptop.

Step 1: Gather the necessary tools

Before you begin the replacement process, make sure you have all the necessary tools. You will need a small Phillips screwdriver, a flathead screwdriver, a pair of tweezers, and thermal paste for reapplication. It's also a good idea to have a soft cloth or an antistatic mat to protect the laptop's surface during the procedure.

Step 2: Power off and disconnect

Start by shutting down your laptop and disconnecting it from any power source. This step is crucial to ensure your safety and prevent any potential damage to the laptop or yourself during the replacement process.

Step 3: Remove the back cover

Flip your laptop over and locate the screws on the back cover. Use the small Phillips screwdriver to remove these screws and set them aside in a safe place. Gently pry open the back cover using a flathead screwdriver or your fingertips, being careful not to damage the laptop's casing.

Step 4: Locate the fan

Once the back cover is removed, you should be able to locate the fan. The fan is typically positioned near the center or side of the laptop, depending on the model. It is connected to the motherboard via a cable, so take note of its position before proceeding.

Step 5: Disconnect the fan

Using a pair of tweezers, carefully disconnect the fan's cable from the motherboard. Take your time and ensure that you do not damage the cable or any surrounding components. Once the cable is disconnected, set it aside.

Step 6: Remove the old fan

With the cable disconnected, you can now remove the old fan from the laptop. The fan is typically held in place by a few screws. Use the small Phillips screwdriver to remove these screws and set them aside. Carefully lift the fan out of its position and place it aside.

Step 7: Install the new fan

Take the new fan and align it with the screw holes on the laptop. Gently place the fan into position and secure it with the screws you removed earlier. Make sure the fan is properly seated and does not wobble or move around.

Step 8: Reconnect the fan

Reconnect the fan's cable to the motherboard using the tweezers. Ensure that the connection is secure and properly aligned. Take your time to avoid any damage to the cable or motherboard.

Step 9: Apply thermal paste

Before reassembling the laptop, it's important to apply a fresh layer of thermal paste to the CPU. This paste helps to transfer heat away from the CPU and onto the fan. Apply a small pea-sized amount of thermal paste onto the CPU and spread it evenly using a clean cloth or a plastic card.

Step 10: Reassemble the laptop

Carefully place the back cover back onto the laptop and secure it with the screws you removed earlier. Make sure all the screws are tightened but not overly tightened, as this could damage the laptop's casing. Once the back cover is securely in place, you can reconnect your laptop to the power source.
