REPAIR TIME & SKILL LEVEL:

This repair is estimated to take about 2 to 3 hours to complete and is of moderate to high difficulty, requiring careful disassembly and attention to small parts and connectors.

STEPS:

Tools You Need

You’ll need a Phillips screwdriver, plastic pry tool, soldering iron (optional), flat metal spudger, wire snips, adhesive (B7000 recommended), and clamps or a heavy object to press the keyboard.

Remove Bottom Case Screws

Flip the ThinkBook over to access the back panel.
Use a Phillips screwdriver to remove all visible screws.
Set the screws aside in a safe container.

Pry Open the Case

Insert a plastic pry tool between the top and bottom case seams.
Work around the edges to release all internal clips.
Carefully lift the bottom panel away.

Disconnect Battery

Locate the battery connector on the motherboard.
Gently unplug it to ensure the unit is safe to work on.
This step prevents accidental power during disassembly.

Remove Battery

Unscrew the three Phillips screws securing the battery.
Carefully lift and remove the battery.
Set it aside in a safe spot.

Remove Storage Devices

Unscrew and unplug the 2.5″ hard drive.
Remove the SSD by unscrewing and gently lifting it out.
Set both drives aside.

Disconnect Wi-Fi Card

Unplug the Wi-Fi antenna cables.
You can leave the card screwed in as it won’t block keyboard access.

Disconnect Internal Cables (Right Side)

Unplug the right-hand speaker connector.
Disconnect the LCD cable at the top.
Unplug the trackpad cable, keyboard ribbon, and keyboard backlight cable.

Disconnect Internal Cables (Left Side)

Disconnect the IO board cable.
Unplug the cooling fan connector.
Leave the BIOS speaker plugged in.

Remove Cooling Fan

Unscrew the fan.
Unroute the Wi-Fi antenna cables from their clips.
Remove the cooling fan.

Unscrew the Logic Board

Remove all screws holding down the motherboard.
Gently lift the board while opening the laptop slightly to loosen the hinge.
Set the board aside.

Remove IO Board and Brackets

Unscrew the left LCD hinge screw and small bracket near the USB port.
Remove the screw holding the IO board.
Lift and remove the IO board.

Unplug the Power Button Assembly

Peel back the tape covering the power button cable.
Unplug the power button cable from the board.

Remove Power Button

Use a plastic spudger to lift the power button from the top case.
Take note of how the button sits on two plastic standoffs.

Remove Tape Covers

Peel off two adhesive layers and a protective cover blocking keyboard access.
This will expose the plastic rivets securing the rigidity plate.

Melt or Cut Plastic Rivets

Use a soldering iron at 150-180°C to melt the heads of the rivets.
Alternatively, use wire snips or a flat metal pry tool to cut off the rivet heads.
This step can take time—be thorough.

Remove Rigidity Plate

Once all rivets are cut or melted, lift and remove the rigidity plate.
Temporarily move the right speaker out of the way.

Remove Old Keyboard

Push the old keyboard up from below.
Lift it out of the top case.
Discard the worn-out keyboard.

Install New Keyboard

Lay the new keyboard face-down into position.
Press it down so it clicks onto the remaining standoffs.

Reattach Rigidity Plate

Place the rigidity plate back down onto the keyboard.
Apply adhesive (like B7000) to the bottom before placing.
Clamp or press it for 30–60 minutes.

Reinstall Power Button

Lay the power button switch and board back into place.
Make sure it aligns with the posts and arms.
Screw it in and reconnect the two cables (LED and main).

Reinstall IO Board

Reinsert the IO board and secure with screws.
Close the left hinge and screw it back down.
Route Wi-Fi antenna cables through grommets.

Reinstall Logic Board

Position the logic board back into the case.
Secure it with all screws.
Reconnect Wi-Fi antennas and place the shielding cover.

Reconnect Cables (Right Side)

Reconnect LCD cable, right speaker, and trackpad.
Peel protective layers and stick keyboard ribbons to their places.

Reconnect Cables (Left Side)

Plug in keyboard backlight ribbon.
Reconnect IO board cable, power button cable, and LED.

Reinstall Cooling Fan

Plug in and route the fan cable.
Ensure antenna wires are under the fan correctly.
Screw the fan into place.

Reinstall SSD and 2.5″ Drive

Slot the SSD into position and screw it in.
Do the same for the 2.5″ HDD.

Reinstall Battery

Slide the battery into place.
Screw it down with 3 Phillips screws.
Reconnect the battery cable.

Reattach Bottom Case

Carefully route the speaker cable to avoid pinching.
Press the bottom case on until it clicks into place.
Reinsert and tighten all screws.

Flip the laptop over and connect the charger.
Power on the laptop.
Confirm the keyboard, backlighting, and trackpad are working.
