Introduction

This guide provides a quick and simple fix to one of the most common problems concerning this device. Before continuing it should be noted that this battery is a lithium ion battery. Any puncturing to the outer shell of the battery could risk a corrosive hazard as well as releasing flammable vapors.

Tools

Step 1

Before disassembling, power off the device.
There are four 11.0 mm screws located at each corner on the back of the device.
With the T5 torx screwdriver, remove these screws and set aside in a safe place.

Important note! Remove the memory chip before starting any of this.

I didn't do this, and when I put it back together the chip slipped underneath the circuit board, and I didn't notice, and when I tightened the circuit board down it munched the chip.😬🫤

Luckily it only lost the last three months or so of data!

Step 2

Using the plastic opening tool, pry apart the device around the seam.

Step 3

Observe the ribbon connecting the screen to the circuit board.
Detach the clip using the plastic opening tool and set aside the screen.

There's not enough information how to do this step. More details are needed. Do you pull on the ribbon? Exactly where do you apply the plastic tool to pry? I could not see how and where it would come out. I did not want to do it wrong, and damage something, so I left it attached while I replace the battery.

It definitely was more awkward!

More pictures of the progress as it happens, and pictures of how it looks like detached would be helpful🤩

Step 4

Using the T5 Torx screwdriver, remove the two remaining 5.0 mm screws.
Lift the board from its housing and then detach the plug coming from the battery.
