Battery Disconnect

Unplug all cables and fully shut down your laptop.

Insert a straightened paper clip into the micro SIM card tray hole on the right edge of the laptop.

Press the paper clip firmly into the hole to eject the tray.

Remove the tray.

Lay your laptop upside down to access the external battery.

Two sliding tabs secure the battery.

Slide the left tab, labeled 1, to the unlocked position—it'll click into place and release the left side of the battery.

Hold the right tab, labeled 2, in the unlocked position and slide the battery out of its recess.

Use a Phillips screwdriver to loosen the eight captive screws securing the back cover.

Insert the flat side of an opening pick between the bottom right edge of the back cover and frame.

Pry up the back cover to release the bottom right clips.

Leave the pick inserted in the bottom right corner.

Slide the pick to the bottom left corner to release the bottom clips.

Insert your pick in the bottom left corner and slide the pick to the first USB port to release the left clips.

Insert an opening tool between the top left corner of the back cover and frame.

Pry the back cover up to release the clips securing its top left corner.

Repeat the process on the top right corner.

Five clips secure the top edge of the back cover.

Insert an opening tool in the gap between the back cover and frame, next to one of the clips.

Push the opening tool into the gap until the clip releases.

Push the opening tool between the back cover and frame at different points along the top edge to release the remaining clips.

Remove the back cover.

Push on alternating sides of the internal battery connector with a spudger to "walk" it out of its socket.
