Steps 1. Peel the tape that secures the camera-cable connector latch to the system board. 2. Open the latch and disconnect the camera cable from the system board. 3. Lift the camera cable off the system board. 4. Disconnect the left-fan cable from the system board. 5. Using the pull tab, disconnect the I/O-board cable from the system board. 6. Lift the I/O-board cable off the system board. 7. Using the pull tab, disconnect the headset-port cable from the system board. 8. Move the headset-port cable off the system board. 9. Open the latch and disconnect the power-button cable from the system board. 10. Disconnect the speaker cable from the system board. 11. Open the latch and disconnect the keyboard-controller board cable from the system board. 12. Remove the screw (M2x3) that secures the wireless-card bracket to the system board. 13. Lift the wireless card bracket off the system board. 14. Disconnect the antenna cables from the wireless-card on the system board. 15. Remove the four screws (M2x3) that secure the system-board and heat-sink assembly to the palm-rest and keyboard assembly. 16. Remove the screw (M2x4) that secures the system board to the palm-rest and keyboard assembly. 17.

NOTE: Before returning the old system board. Adhere the processor (CPU) sticker over the processor (CPU) chip surface and ensure that it is fully covered . NOTE: When replacing the system board for computers with a M.2 2230 solid-state drive installed, ensure that the M.2 2230 solid-state drive mounting bracket has been removed from the system board and installed on the new system board. CAUTION: Once the system-board assembly has been removed from the computer, follow the instructions in the tech sheet dispatched with the replacement system-board assembly. CAUTION: Do not use an alcohol wipe to clean the Element 31 thermal grease from the processor (CPU) chip which is surrounded by the processor (CPU) barrier sheet. The alcohol solution from the wipes will dissolve the Element 31 grease into conductive metal particles. If these conductive metal particles come into contact with the surface of the system board, it will cause the an electrical short when your computer is powered on. 54
