    • Open the housing plate.

    • Be gentle with the wires still connected to the logic board so as not to ruin the cables.

    • A fixed plug connector between the logic board and upper unit will cause some resistance. Pull gently but firmly.

We are not allowed to use screwdrivers to pry open stuff. Unfortunately, that is exactly what we did in step 6 of Dissasembling the back up battery

Don't you need to replace the thermal paste?

I love my very first Mac ever, it is still working. After a couple of time living with its amnesia (forgot time and what else…) I’ve decided to replace the battery. Thanks for this helpful article. It made it easy to me to replace the battery.
