❓ WHEN SHOULD THE BOTTOM CASE BE REPLACED?

• A cracked case after the laptop was dropped
• A stripped thread or broken mount, so the cover lifts at the edge
• A bent cover that makes the laptop rock on the desk
• A heavily scratched or chipped underside that spoils the look when reselling
• Missing rubber feet or a damaged vent grille

🔧 INSTALLATION PROCESS

1. Power off the laptop and disconnect the power supply and all external devices
2. Place the laptop upside down on a soft, clean surface
3. Loosen the bottom cover screws (they stay in the cover)
4. Gently pry the cover up from the hinge side and release it from the clips
5. Fit the new cover, pressing the clips in all around
6. Tighten the screws and check that the cover sits flush
Installation by a technician or a person experienced in laptop repairs is recommended.
