STEPS:

Tools You Need

For this repair, you will need a Torx screwdriver set (T3, T6 sizes), a plastic pry tool for lifting the keyboard, a small flat tool for adhesive removal, and a spudger for safely disconnecting delicate connectors.

---

Remove the Keyboard Assembly

• Locate the hidden screws under the rubber feet and carefully unscrew them using a Torx driver.
• Use a plastic pry tool to lift the keyboard assembly; it’s held by magnets and an attached ribbon cable.
• Gently detach the ribbon cable and set the keyboard and touchpad unit aside.

---

Remove Protective Covers and SSD

• Carefully pry up the metallic covers; be cautious as edges can be sharp.
• Unscrew the T3 screws securing the SSD and gently remove the small M.2 SSD from its slot.
• Keep track of all screws using a magnetic tray, as magnets around the frame may attract them.

---

Disconnect and Remove Charger Connector

• Locate the charger connector assembly and carefully lift it out of place.
• Set the charger connector aside in a safe spot to avoid losing small parts.

---

Remove Heat Sink and Fan Assembly

• Disconnect the fan ribbon cable carefully by pulling it straight out.
• Unscrew and lift the heat sink, which may resist due to thermal paste adhesion.
• Set the heat sink and fan assembly aside on a clean surface.

---

Take out the Speakers

• Locate the left and right speakers and gently pry them out of the housing.
• Disconnect any attached cables as you remove each speaker.
• Place the speakers aside, keeping them organized for reassembly.

---

Remove Additional Covers and Antenna Bar

• Remove additional small protective covers by prying them from one corner and lifting carefully.
• Unscrew and disconnect the antenna bar cable and antenna assembly.
• Keep the antenna bar separated from other parts to prevent confusion.

Disconnect Display Connectors

• Locate and remove spacer bars covering display cable connections.
• Pry up display cable connectors using a spudger, carefully lifting them away from the board.
• Remove all necessary screws to free the display assembly.

---

Remove the Screen

• Support the display with one hand while unscrewing the final T6 screws securing it.
• Lift the screen up and away gently once screws are fully removed.
• Set the display aside or replace it if it’s the component you’re servicing.

---

Remove Additional Motherboard Connectors

• Remove any covers protecting the connectors near the motherboard.
• Unscrew any remaining screws around the motherboard area.
• Detach all connectors gently, ensuring no cables are snagged.

---

Take away the Motherboard

• After ensuring all screws and cables are free, lift the motherboard carefully out of the housing.
• Inspect both sides for any remaining connections or damage.
• Set the motherboard aside on an anti-static mat.

---

Remove the Audio Jack Connector

• Find and carefully disconnect the audio jack connector.
• Remove the connector completely and place it with the other small parts.
