For your safety, discharge the battery below 25% and power down your device before disassembly.

Use a Phillips screwdriver to remove the 10 screws securing the back cover:

Seven 11.6 mm screws

Two 14.6 mm screws

One 6 mm screw

Use a Phillips screwdriver to loosen the captive screw.

Loosening this captive screw will pop up and separate the bottom-right corner of the back cover from the chassis.

During reassembly, tighten the captive screw before the rest of the screws.
