Steps:
- For your safety, discharge your battery below 25% before disassembling your laptop. A charged battery may catch fire if damaged. If your battery is swollen, take appropriate precautions.
- Completely shut down your laptop (don't just put it in sleep mode) and disconnect all cables.
- Flip the laptop upside-down, and rotate it so the screen hinge faces towards you.
- Use a Phillips screwdriver to fully loosen the seven captive screws securing the base cover.
- Insert your fingernail or an opening pick into the gap between the base cover and keyboard deck, next to one of the screen hinges.
- Pry up the base cover until the clips unfasten.
- Grasp the base cover along the screen hinge edge and lift slowly to unfasten the remaining clips.
- Lift and remove the base cover.
- During reassembly, lay the base cover into the frame, inserting it into the tabs along the battery edge. Press down firmly around the perimeter to reengage all the clips.
- Because of the battery connector's design, the only way to disconnect the battery is by physically removing it.
- Use a Phillips screwdriver to fully loosen the two captive screws securing the battery connector.
- Lift the edge of the battery with the connector to disconnect it.
- You may feel a little resistance from the battery connector as it disconnects—that's normal.
- Remove the battery
- During reassembly:
- Slide the plastic tabs on the long edge of the battery into their recesses in the frame.
- Lower the battery into place so the connector goes over its socket.
- Use a spudger to gently push under the metal buckle of the camera cable connector to unclip it
- Grab the buckle and cable together and gently pull the connector straight out of its socket.
- Hold the buckle and cable together and guide the cable out of the clips holding it to the fan.
- Use the point of a spudger to push on alternating sides of the fan connector to "walk" it out of its socket until fully disconnected.
- This connector has a small marking that shows which side of the connector should be facing up. To reconnect, align the connector and use a spudger or clean fingernail to push it fully into the socket.
- Use a Phillips screwdriver to fully loosen the five captive screws securing the fan and heatsink.
- During reassembly, tighten the screws in an "X" pattern in the order labeled: bottom left, top right, bottom right, top left.
- Pick up the fan and heatsink assembly by its edges and remove it from the laptop.
- You may feel a little resistance from the thermal paste and pads between the heatsink and the components on the motherboard—this is normal.
- Before installing a new heatsink, follow this guide to clean the CPU and reapply thermal paste.
- If you're only reapplying thermal paste and not replacing the heatsink, clean the bottom of the heatsink as well.
