  • Remove the following eight screws securing the lower case to the chassis:

    • One 3 mm Phillips screw.

    • Three 13.5 mm Phillips screws.

    • Four 3.5 mm Phillips screws.

On my model, it seemed the top-left was 3.5mm and the bottom 4 were 3 mm.

Make sure you have a good quality Phillips screwdriver. Mine had removable tips and had a small play at the connection. As a result I didn't have a good feel and damaged my screws (those securing the fan and the top left in step 23). Game over for me installing new thermal paste...

Be very carefull with your screws! Especially those on the inside.

When reinstalling the battery connector/cable, placement of the connector is critical. If the connector isn't positioned accurately, contact with the battery terminals won't be completed. The battery connector cover will help you align the connector, but there will still be a little leeway as you screw the cover down. Position the battery first, to adjust the connector's position; then remove the battery and tighten the cover screws down. You may even want to try plugging the computer into the AC charger before completing the cover attachment, to ensure that battery is charging and the connector is correctly positioned.
