Steps for Replacing the LCD Screen

- Remove Additional Components: If required, disconnect the DC jack/power charger component and the speakers to access the screen connectors.
- Loosen the Motherboard: Use the appropriate torx screwdrivers to loosen the motherboard slightly. This step is crucial for safely removing the LCD screen without damaging the connectors.
- Remove the LCD Connectors: Carefully open the clippers holding the LCD cables and gently disconnect them. Ensure you’re using a plastic tool to prevent any electrical shorts.
