Introduction

Use this guide to replace the fingerprint sensor in your Galaxy Book Pro 15" Laptop with a genuine Samsung part.

For your safety, discharge the battery below 25% before disassembling your device. This reduces the risk of a thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

Parts

Step 1

Before you begin, power down your laptop and unplug it.
There are two kinds of rubber feet along the top and bottom of the rear case. Keep track of their position as you remove them.
Insert an opening pick between the rubber foot and the rear case.
Pry up with the opening pick to release the clips securing the foot.
Remove the foot.
Repeat this procedure for the three remaining feet.
During reassembly, press the feet into their correct slot to reinsert them. Mismatched feet won't fit correctly.

Step 2

Use a Phillips screwdriver to remove the four 4.5 mm-long screws securing the rear case.

Step 3

Apply a suction cup to the rear case, as close to the center of the bottom edge as possible.
Pull up on the suction cup with strong, steady force to create a gap between the rear case and the frame.
Insert an opening pick into the gap.

Step 4

Slide the pick along the bottom edge of the rear case to release its plastic clips.
Repeat this process for the left and right edges, but stop before reaching the top edge.

Step 5

The top edge of the rear case is lightly adhered to the frame.
Pull the top of the rear case away from the frame to separate the adhesive and release the remaining clips.
If you're having trouble separating the adhesive, use an iOpener, hair dryer, or heat gun to soften it.
Remove the rear case.
During reassembly, perform the following:
If you're using a using a genuine Samsung replacement rear case, be sure to peel off any adhesive liners from the rear case before securing the top edge's clips.
If you're reusing your rear case, you can use some pre-cut adhesive to re-adhere the top edge if your existing adhesive is no longer sticky.
This is a good point to power on your laptop and test all functions before sealing it up. Be sure to power your laptop back down completely before you continue working.

Step 6

Insert a spudger between the frame and the bottom of the battery cable connector.
Pry up and disconnect the battery cable connector.

Step 7

Use a spudger to pry up and disconnect the bottom left speaker connector from the daughterboard.

Step 8

Use a spudger to gently pry up the locking flap on the daughterboard ZIF connector for the interconnect cable.

Step 9

Disconnect the interconnect cable by sliding it out from its socket on the daughterboard.

Step 10

Use a spudger to gently pry up the locking flap on the ZIF connector for the keyboard backlight cable.

Step 11

Disconnect the keyboard backlight cable by sliding it out from its socket on the daughterboard.

Step 12

Use the tip of a spudger to pry up and disconnect the two WLAN antenna cables.
Pry under the bottom of the cable's metal head and not the cable itself.
During reassembly, these can be tricky to reconnect. One at a time, hold each connector in place over its socket and press down with the flat end of a spudger. The connector should snap into place.

Step 13

Use a spudger to pry up and unclip the antenna cables from their slots on the daughterboard.

Step 14

Use the flat end of a spudger to pry up and disconnect the fingerprint sensor's press connector from the daughterboard.

Step 15

Use a Phillips screwdriver to remove the four 3.5 mm-long screws securing the daughterboard.

Step 16

Use tweezers, or your fingers, to remove the daughterboard port bracket.

Step 17

Tilt the right edge of the daughterboard upward to separate it from its pegs in the frame.
Pull the daughterboard toward the right edge of the laptop to separate the headphone jack and the HDMI port from their recesses in the frame.
Remove the daughterboard.
During reassembly, be sure to reinsert the daughterboard at a downward angle to position the headphone jack and the HMDI port back into their recesses.
