Step‑by‑Step Keyboard Replacement Procedure

1. Power Down and Disconnect

Shut down the laptop completely.
Unplug the AC adapter and all external devices.
Hold the power button for 10 seconds to discharge any residual charge.

2. Remove Bottom Cover

Use a Torx T5 screwdriver to remove all screws on the underside of the chassis.
Lift the cover carefully with a plastic pry tool to reveal internal components.

3. Disconnect the Internal Battery

Locate the battery connector on the system board.
Disconnect it gently to prevent current flow to the keyboard circuit during disassembly.

4. Access the Keyboard Assembly

The keyboard is integrated into the top case.
Remove components that obstruct access, such as the speakers or internal brackets, according to Lenovo’s Hardware Maintenance Manual.

5. Release Keyboard Screws

From the underside of the top case, locate the screws marked with a small keyboard icon.
Unscrew them carefully and keep them in order.

6. Remove the Old Keyboard

Flip the laptop over and open the display to 90 degrees.
Use a spudger to release the clips along the top edge of the keyboard.
Tilt the keyboard forward, carefully disconnect the FPC ribbon from the ZIF connector, and remove the assembly.

7. Install the New Keyboard

Align the new Lenovo ThinkPad X1 Carbon Gen 2 keyboard precisely in the top case.
Reconnect the FPC into the ZIF connector and lock it.
Re‑secure all screws and retention clips.

8. Reassemble and Test

Reinstall the internal components (speakers, brackets) in their original positions.
Reconnect the battery, close the bottom cover, and secure it with Torx screws.
Power on the device and run a full keyboard diagnostic test.
