Before you begin, discharge your laptop battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured. Lay the device down with the lower case facing up.

Power off your laptop and disconnect the charger and any peripheries before beginning disassembly.

Unscrew the nine 5 mm Phillips #00 screws that secure the lower case.
