Introduction

Use this guide to replace a broken fan in your Lenovo IdeaPad 3-15IIL05 laptop.

You may need to replace the fan if your laptop is overheating.

Allow your laptop's battery to drain below 25% before starting this repair—a charged battery may catch fire if damaged.
Unplug all cables and fully shut down your laptop.

Plastic clips secure the back cover to the frame. You'll hear and feel the clips release.
Insert the flat side of an opening pick between the top left corner of the back cover and frame.
Angle the pick down to about 45 degrees.

Keep the opening pick angled down at about 45 degrees while sliding it along the front and side edges to help release the clips.
Slide the pick to the bottom left corner of the laptop to release the left clips.

Insert the flat end of an opening pick between the back cover and frame, to the left of the right hinge.
Pry the back cover up with the pick to release the top right clips.
Leave the pick inserted next to the right hinge.

Remove the back cover.
During reassembly, lay the back cover on the frame and press firmly around the perimeter to engage all the clips.

Use the flat end of a spudger to gently push the battery connector out of its socket on the motherboard.

Push on alternating sides of the fan cable connector with a spudger to "walk" it out of its socket.

Slide one arm of your angled tweezers under the head of the gray antenna cable connected to the WLAN card.
Gently lift straight up to disconnect the cable.
Repeat the same process to disconnect the black antenna cable.
To reattach antenna connectors like these, align the connector over its socket and press down with the flat end of a spudger. The connector should snap into place. This can be tricky and may take a few tries.

Use a Phillips screwdriver to remove the three screws securing the fan:
Two 4.4 mm-long screws
One 5.6 mm-long screw
Before installing the screws during reassembly, make sure the black and gray antenna cables aren't under the fan.
