Tools You Need

For this repair, you will need a T4 screwdriver for the back plate, a plastic wedging tool for prying open the case and components, a Phillips screwdriver for internal screws, and your fingernails or a plastic tool to safely disconnect the SSD and Wi-Fi card. It’s also helpful to have isopropyl alcohol for loosening adhesive and a heating mat is optional but not required for this disassembly.

Remove the Back Plate

• Use a T4 screwdriver to remove all screws from the back plate of the laptop.
• Insert a plastic wedging tool between the case seam on the right-hand side and gently glide along the edge until the tabs begin to pop open.
• Repeat the same process along the bottom edge to fully detach the back cover.

---

Disconnect the Battery

• Locate the battery cable and gently lift the pull tab.
• Pull the cable out from the tape side to safely disconnect the battery.
• Press and hold the power button for about 10 seconds to fully discharge any residual power in the unit.

Remove the Battery

• Unscrew the battery screws and lift the battery up using the small straps on either side.
• Carefully pull the battery out and set it aside in a safe location.

---

Disconnect SSD and Remove It

• Unscrew the SSD retaining screw to loosen it.
• Use a wedging tool to gently lift the SSD and adhesive plastic bracket.

Disconnect Wi-Fi Card

• Unscrew the retaining screw on the Wi-Fi module.
• Use your fingernail to lift and pull the Wi-Fi card out gently from the slot.

---

Disconnect Flex Cables and Fan Cables

• Unplug all flex cables connected to the main board and sideboard, as well as the left and right fan cables.
• Gently lift the protective latches on each cable connector before pulling out the ribbon cables.
• Be very delicate with these as they are fragile and can break easily.

---

Remove Heat Sink and Phillips Screws

• Remove all Phillips screws from the motherboard using a small Phillips head screwdriver.
• For the heat sink screws, unscrew them at an angle to avoid putting pressure on the CPU or GPU chips.
• Lift out the heat sink and fans once all screws are removed.

Disconnect Speaker Cables

• Gently pull the small speaker cable on the left side out from its connector.
• Repeat this step for the right speaker cable using gentle prying motions.

Remove the Motherboard

• Once all cables and screws are removed, gently pry the motherboard upward from one edge.
• Loosen any cable tension still holding the board down and slowly lift the motherboard out of the chassis.

---

Remove the Daughterboard

• Locate the daughterboard on the left side of the device.
• Release tension from the bracket and gently lift it until it pops free from its position.

---

Remove the Speakers

• Use your plastic tool to carefully pry up the speakers from their resting slots in the chassis.
• Take care not to damage the wires as you remove them from each corner of the case.

---

Detach the LCD Display from the Case

• Extend the display hinges as far as they go to loosen the screen.
• Bend back the bottom case slowly until it separates from the LCD screen assembly.
• Once the hinges are fully extended and tension is released, the LCD panel will come free.
