Introduction

Use this guide to replace the motherboard in your Galaxy Book Pro 15" Laptop.

Before you begin, refer to the Samsung PC Repair Guide for safety information.

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.

Note: Some photos show the heat sink removed. This is optional, as you don't need to remove the heat sink to remove the motherboard.

    • 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.

    • 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.

Conclusion

To reassemble your device, follow the instructions in reverse order and perform the opposite actions, e.g., "reattach" instead of "removing." Skip steps that use heating and prying, and pay close attention to the 📌 bullets as you work through the steps.

Take your e-waste to an R2 or e-Stewards certified recycler.
