3. Remove the RAM: Release the clips holding the RAM modules in place and gently pull them out.
4. Remove the wireless card: Remove the screws holding the wireless card in place and disconnect the antenna cables. Gently pull the card out.
5. Remove the fan and heatsink: Remove the screws securing the fan and heatsink to the motherboard. Disconnect the fan cable and gently remove the assembly.

Step 5: Replacing Components

1. Install the new components: Insert the new components into their respective slots or bays. Ensure they are properly seated and secured.
2. Reconnect the battery connector: Connect the battery connector to the motherboard.
3. Reassemble the laptop: Reverse the disassembly steps, starting with the fan and heatsink, then the wireless card, RAM, and hard drive. Secure the bottom cover with the screws and clips.
4. Power on and test: Connect the power adapter and turn on the laptop. Verify that all components are working correctly.
