Lenovo Yoga Book X90F Speakers Replacement

Introduction

Lenovo Yoga Book X90F. Model number: Lenovo YB-J912F. This guide will help to replace the right and left speakers if there is no audio playback. The relevant troubleshooting section can be found using this link.

The speaker is responsible for audio volume and quality, so poor audio quality will require a speaker replacement.

Prior to starting the replacement, please turn the power off on the computer and disconnect any external power sources, such as the device charger.

What you need

Step 1 Bottom Screen/Keyboard

Turn off and power down the device before beginning this process. A heat gun or hair dryer will be suitable to heat the adhesive that holds down the screen. Apply heat to the entire surface area of the bottom screen.
New adhesive will be required when completing the steps in reverse order.

Edit

Step 2

Once the adhesive has been heated up, take the iFixIt suction cup and lift in a corner. The screen should be separating from the adhesive here.
While the screen is lifted, insert the ifixit opening pick to help pry off the screen.
The screen may crack easily as it is thin and fragile.

Edit

Step 3

While the screen has been lifted, insert the plastic opening picks. Heat the adhesive and follow with the screen removal tool to ensure that you are not prying it apart with excessive force.

After the screen has been opened, disconnect the ribbon connecting the bottom screen to the motherboard by gently pulling the ribbon with tweezers.
If there are black coverings on the tabs as shown in the second image, carefully remove them using a pair of tweezers.
