Open the case and unpeel the 2 black stickers in the top corners of the keyboard.

This will reveal the 6 screws that attach the upper cover to the keyboard cover.

Use the T9 Torx screwdriver to unscrew the 2 bigger screws in the middle of each side.

Use the T6 Torx screwdriver to unscrew the remaining 4 screws.

Turn the keyboard cover over so the bottom is facing up. Manually remove the thin black covering that is attached to the bottom.

Be patient, the thin black covering might be really stuck to the bottom.

Once the thin black covering is removed, you will see 15 screws.

Use the T6 Torx screwdriver to remove the screws.

Once the screws are removed, lift off the bottom panel to access the keyboard and battery.

You are done.
