    • Use a Phillips #00 screwdriver to remove one 5.0 mm screw from the back of the laptop.

    • Use a Phillips #00 screwdriver to remove nine screws from the chassis.

    • Use a spudger or opening tool to remove the chassis and reveal the battery, fan, motherboard, and other components.

    The Wlan cable holds the base to the computer along with a little wire in the back left corner.

    • To the upper right of the battery is a connecting cable. Gently disconnect it from the palm rest assembly.

    • Confirm nothing else is connected to the battery and lift the battery completely off the palm rest assembly.

    While I did finish my battery replacement using this guide, I had to remove around 15 screws to release the midframe, not the nine listed. This is likely due to the source machine being a different h/w version than mine. It still didn't take long and wasn't much more difficult. I swapped a 68Wh dead battery with a 99Wh version. Now it lasts around 7 hours on a charge. Much better :D
