If your motherboard is causing issues such as system freezes and random crashes, this guide shows the correct way to remove the motherboard.

Before you begin, power off your device completely and disconnect from the charging adapter.
Flip the laptop over so the bottom is facing up.
Use a Phillips #1 screwdriver to remove ten 5.6 mm screws from the back panel.
Place the end of an opening tool in the seam between the bottom and top case and slide it around the perimeter to release the clips holding it together.
Use a few opening picks in the seam to keep the clips from reattaching.
Remove the back panel.

Use the point of a spudger to push on alternating sides of the battery connector to "walk" it out of its socket on the motherboard.
It may take a lot of alternating before the connector comes out. Be patient, and don't pull on the cables.
To reconnect the cable, align the connector and use a spudger or clean fingernail to push it fully into the socket.
Don't push on the cables themselves, or you may damage the connector.
Lift the battery upwards to remove it from the device.

Use the end of a spudger to push on alternating sides of the sliding connector and remove it from the socket on the motherboard.

Use a Phillips #1 screwdriver to remove the two 3 mm screws attaching the fan to the chassis.
Slide the fan out from the socket to remove it.

To disconnect the speaker cable, use the point of a spudger to push on alternating sides of the connector to "walk" it out of its socket.
Don't pull on the cables.

Slide a thin, ESD-safe pry tool or angled tweezers under the metal neck of the white coaxial cable connector (as close to the head as possible) and lift straight up from the board.
Repeat to disconnect the black coaxial cable connector.

Use a Phillips #1 screwdriver to remove the 2 mm screw securing the Wi-Fi card to the motherboard.
Slide the Wi-Fi card out from the socket.

Use a spudger or a clean fingernail to flip up the locking flap on the four ZIF connectors—this is the unlocked position.
Use tweezers or your fingers to gently pull each cable out of its socket.
Try pushing on alternating sides of the CMOS battery connector with a spudger to disconnect it from the socket.
If that doesn't work, use a pair of tweezers to firmly grip the sides of the connector and pull straight away from the socket. Hold the tweezers closer to the connector to get a better grip.
To disconnect the display connector, first, gently push the tip of a spudger under the metal buckle to unclip it, then swing it over the socket.
Next, hold the buckle and cable together and gently pull the connector straight out of its socket.
Use the point of a spudger to push on alternating sides of the power connector to "walk" it out of its socket.
Don't pull on the wires or you risk damaging the connector and device.

Use a Phillips #1 screwdriver to remove the four screws securing the motherboard to the chassis.
If your replacement board does not come with a heat sink, remove the three screws in descending order of the inscribed numbers on the heat sink.
If you aren't replacing the heat sink, loosen the screws before removing the motherboard.
Lift the motherboard from the laptop.
