    • Peel back the copper ESD shielding covering the bottom of the motherboard.

    • Do not try to remove the copper shielding, as it is still attached underneath the battery.

If the speakers are to be replaced simply peel back the bottom corner to expose the speaker connection. Leave the rest of the heatsink shield alone.
