    • Use an opening tool to pry the bottom cover from the device.

    • Use the opening tool to go around the entire perimeter, releasing the tabs that secure the cover to the frame.

    • Insert opening picks between the bottom cover and the frame to prevent the case from reconnecting.

    • Carefully remove the cover.

    • Use a Phillips screwdriver to remove the three screws securing the battery to the frame.

    • Be sure not to lose the screws, as you'll need them for the new battery as well.

    • Use the point of a spudger to push on alternating sides of the sliding connector to "walk" it out of its socket on the motherboard.

    • It may take a lot of alternating before the connector comes out. Be patient, and don't pull on the cables.

    • To reconnect the cable, align the connector and use a spudger or clean fingernail to push it fully into the socket.

    • Don't push on the cables themselves, or you may damage the connector.

    • Grip the tab at the end of the bundle cable and pull the connector slowly and steadily out of its socket to disconnect the fan cable.

    • Be careful that you do not damage the socket on the motherboard when disconnecting the fan cable.

    • Use a spudger or a clean fingernail to flip up the locking flap of the ZIF connector—this is the unlocked position.

    • Use the widest tool possible to avoid damaging the delicate hinge pins.

    • Use tweezers or your fingers to gently pull the cable out of its socket by the blue tab.

    • To reconnect, make sure the locking flap is flipped up and gently reinsert the cable. Then, flip the locking flap down to secure the cable. The cable should slide into the socket with little to no force. If you're having trouble, remove it, check that the flap is fully unlocked, and try again.

    • Use a Phillips #0 screwdriver to remove the three 3 mm screws securing the USB board to the chassis.

    • Gently remove the USB board from the frame.

    • Be careful when you remove the board that the ports are disconnected from the edge of the device.

Conclusion

To reassemble your device, follow these instructions in reverse order. Take your e-waste to an R2 or e-Stewards certified recycler.
