ID: 147250

Description:

Steps:

1. Unscrew the nine PH#0 captive screws on the bottom of the device.
2. Use a pick to run along the outside of the device popping all the clips. Prying should not be necessary.

3. Disconnect the daughterboard data cables.

4. Pull the daughterboard power cable out of its socket parallel to the motherboard.

5. Remove the M2x3 screw and cover, and disconnect the antenna cables.
6. Note: be careful on reassembly. Antenna connectors can be troublesome and are easy to damage.

7. Disconnect the touchpad, keyboard, and speakers where shown.

8. Remove the four M2x4 screws, as well as the cover over the LVDS cable (top right).

9. Detach the LVDS cable.
10. The cable is held down with adhesive. Don't be shy about pulling it off the motherboard.

11. Lift the motherboard out from the left side and pull away from the body of the chromebook.
12. During reassembly, it is much easier to insert the motherboard without the IO shield attached. The IO shield is easily inserted after the motherboard is in place.

13. Apply lateral force to the IO shield to break the adhesive holding it to the motherboard.
14. Save this IO shield to put on the new motherboard.

15. During reassembly, make sure to include a thermal pad on the CPU. Usually you can reuse the one from the previous motherboard, but it's best to have access to a new pad in case the old one is not usable.
