Additionally, move the logic board as little as possible while it is outside the
computer case.

You can also press the Power key (marked with a π) on the keyboard.
2 Unplug all the cables except the power cord from the computer (including the cable that
connects your keyboard to the computer).
Leaving the power cord plugged in helps protect the computer from damage
caused by electrostatic discharge. You’ll unplug the power cord later.
