STEPS:

Tools You Need

For this repair, you will need a Phillips head screwdriver, a plastic spudger to help open the bottom case safely without damage, and a replacement CPU fan compatible with the Dell Inspiron 5468 2-in-1 laptop.

---

Flip the Laptop Over

• Place the laptop upside down on a soft surface with the hinges pointing away from you.
• Ensure the device is powered off and unplugged from any power source.
• This position gives you easy access to the bottom panel screws and internal components.

---

Remove Bottom Screws

• Use a Phillips head screwdriver to remove all the screws securing the bottom case.
• Keep the screws organized as they will need to go back into the same locations during reassembly.
• Make sure all visible screws are removed to avoid damaging the bottom panel during prying.

---

Pry Off the Bottom Cover

• Insert a plastic spudger between the seam of the bottom case and the chassis.
• Carefully work your way around the edges to release all the clips holding the panel in place.
• Lift the bottom cover off completely once all clips are disengaged.

---

Disconnect the Battery

• Locate the battery connector and gently unplug it from the motherboard.
• This step is essential to prevent electrical damage while working on internal components.
• Always handle connectors gently to avoid bending pins or damaging sockets.

---

Unplug the CPU Fan

• Identify the CPU fan connector and unplug it from the motherboard.
• Be sure to pull on the connector, not the wires, to avoid damaging the fan cable.
• This frees the fan from the board, preparing it for removal.

---

Remove the Fan Screws

• Remove the two screws that secure the CPU fan to the chassis.
• Use a magnetic screwdriver if possible to avoid losing the screws inside the case.
• Set the screws aside safely for reinstallation.

---

Take Out the Old Fan

• Gently lift the old CPU fan out of its place once unplugged and unscrewed.
• Check for any dust buildup or loose debris in the area that could have caused issues.
• Discard the faulty fan or keep it for inspection.

---

Install the New Fan

• Place the new CPU fan into position.
• Plug the fan into the motherboard before securing it to the chassis.
• This order makes the connection process easier without obstruction.

---

Secure the New Fan

• Reinstall the two screws to hold the new fan firmly in place.
• Double-check that the fan is seated properly and the cable is routed without tension.
• A secure fit ensures proper cooling and prevents vibration noise.

---

Reconnect the Battery

• Carefully plug the battery connector back into the motherboard.
• Make sure the connection is firm and flush without forcing it.
• Proper reconnection is necessary for the laptop to power on.

---

Reattach the Bottom Cover

• Place the bottom cover back onto the chassis, aligning the edges properly.
• Press down around the edges to snap the clips back into place.
• Listen for clicking sounds to confirm the panel is secured.

---

Reinstall Bottom Screws

• Replace all screws removed earlier and tighten them with a Phillips screwdriver.
• Ensure each screw is fully seated to avoid loose panels or rattling.
• Your laptop should now be completely reassembled.

---

Power On and Test the Fan

• Turn on the laptop and watch for the Dell splash screen.
• Listen to ensure the fan spins quietly without grinding.
