    • Use a Phillips #00 screwdriver to remove 10 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.

    Mine has 12 screws not 9. one card also to remove, (held by screw), and 2 sets of connectors

    Plus you need to put the splonger in the edge below the usb connections, not on the area highlighted in the picture above. Yeah there are way more screws than 9. You also need to remove the screws out of any m.2 ssd drives, msata drives, and wlan card. You also need to unplug each ribbon cable, and unplug and unwire the tronlights on both sides of the laptop.

    This youtube video is really helpful for this part: https://youtu.be/QxJznOkvyic?si=eDLzrheu...

    • Use a Phillips #00 screwdriver to remove the 5.0 mm screw that is securing the battery to the palm rest assembly.

    • 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

Craig Anderson -

step 5 - you need to unscrew 10 screws, not 9. You missed the one in the center.
