REPAIR TIME & SKILL LEVEL:

This repair is estimated to take about 2–3 HOURS to complete and is of ADVANCED difficulty, requiring careful handling of delicate internal components and a strong understanding of laptop disassembly and reassembly.

STEPS:

Tools You Need

For this repair, you will need a Phillips screwdriver, a plastic spudger for separating the casing and unplugging connectors, isopropyl alcohol for thermal paste cleaning, fresh thermal paste for reinstallation, and a plastic card for safe prying. You may also need a heating mat if adhesive is present, though it wasn’t required in this specific video.

Use a plastic spudger to carefully separate the bottom panel from the top case.
Set the bottom panel aside for reassembly later.

Disconnect the Battery

Locate the battery connector and gently disconnect it from the motherboard.
This step is crucial to prevent power from running through the board during the repair.
Double-check that no power is flowing before proceeding.
